Icahn Enterprises L.P. did $10.02 billion of revenue in FY2024 with 37 employees. That is not a typo. IEP is a master limited partnership that Carl Icahn owns 86% of, a holding vehicle for seven business segments, and it has no careers page, no applicant tracking system, and no internship program. Its entire web presence at ielp.com is investor relations. The place where a student can actually get hired inside the Icahn empire is CVR Energy (NYSE: CVI), the Energy segment, which employs approximately 1,532 people and generated roughly $7.2 billion in net sales in 2025 running two mid-continent refineries: 132,000 barrels per day at Coffeyville, Kansas and 74,500 barrels per day at Wynnewood, Oklahoma, plus about 920 miles of pipeline and 98 crude oil transports. As of September 7, 2026, CVR Energy has 30 open requisitions, and two of them are Chemical Engineering Intern (Summer 2027) roles at Wynnewood. The Icahn Enterprises internship, in practice, is a refinery internship in a town of a few thousand people in south-central Oklahoma. One more thing: Pep Boys is no longer an Icahn business. Mavis Tire Express completed its $700 million acquisition of Pep Boys on August 20, 2026. Guides routing you to Pep Boys for an Icahn internship are out of date.

What Is an Icahn Enterprises Internship?
An Icahn Enterprises internship does not exist at the parent level. Icahn Enterprises L.P. (Nasdaq: IEP) is a Delaware master limited partnership with 37 employees, seven business segments, and no careers website. The internship that actually exists sits at CVR Energy (NYSE: CVI), the Energy segment, which operates two mid-continent petroleum refineries and a nitrogen fertilizer business. CVR employs approximately 1,532 people and generated roughly $7.2 billion in net sales in 2025. The Wynnewood, Oklahoma refinery where both Summer 2027 intern seats are posted is a 74,500 barrel-per-day complex refinery producing gasoline, diesel including renewable diesel, military jet fuel, solvents and asphalt. CVR's stated core values are Safety, Environment, Integrity, Corporate Citizenship and Continuous Improvement. Employees rate CVR 2.9 out of 5 on Indeed from 73 reviews, with pay and benefits at 3.2 (the highest category) and management at 2.3 (the lowest).
When Do Icahn Enterprises Internship Applications Open for 2027–2028?
The Icahn Enterprises parent does not recruit. CVR Energy posts internships to its own ADP career site, and the Summer 2027 cycle opened in early September 2026 with two Chemical Engineering Intern requisitions at the Wynnewood, Oklahoma refinery. CVR publishes no application deadline, no open date on the requisitions themselves (ADP's posting-date field returned null), and no program calendar. Indeed's relative timestamps place both postings around September 2, 2026. With only two seats and no deadline, these roles could fill at any point between now and spring 2027. The practical advice is to apply now, because the window's close is invisible.
Two Chemical Engineering Intern (Summer 2027) requisitions are live at CVR Energy's Wynnewood, Oklahoma refinery. Apply through cvrenergy.com/Company/Careers. With only two seats and no published deadline, early application is the only hedge against an invisible close.
Rolling review with two seats. No deadline is published, but with a 1,532-person company and only two intern openings, the class could be filled well before the calendar turns. Apply in September, not in January.
If the requisitions are still live, interviews and offers proceed. CVR publishes no timeline for its hiring process. The one public intern interview account describes a straightforward experience.
Hands-on refinery internship at CVR Energy's Wynnewood, Oklahoma complex. HSSE orientation first, then preventive maintenance, troubleshooting, instrument repairs, plant operator shadowing, and a process-improvement project with an assigned mentor.
How to read this page: our dates come from tracking previous recruiting cycles and daily posting data. Treat them as informed estimates based on historical patterns, not confirmed dates. The company's official careers page is always the most current source. If a role is posted there, go by that, even if this page suggests the window hasn't opened yet.
Why You Must Apply the Week Applications Open
Two seats. That is the whole argument. CVR Energy is a 1,532-person company with 30 open requisitions, two of which are Chemical Engineering Intern (Summer 2027). There is no published deadline, no published close date, and no way to know when those two seats fill. Unlike a Fortune 500 employer with 200 intern slots and a stated application window, CVR's program is small enough that a single week's delay could mean the difference between two available seats and zero. The requisition has been live since approximately September 2, 2026. Every week you wait is a week closer to a quiet close on a board that does not announce it. And because CVR publishes no interview timeline, no cohort announcement, and no program calendar, the first signal you will get that the window has shut is the requisition disappearing from the ADP board. Apply now, and apply to both requisition IDs (1870 and 1871), because they are two seats, not one posting listed twice.
Which Icahn Enterprises Internship Programs Should You Target?
Icahn Enterprises does not run an internship program. Its subsidiary CVR Energy runs a refinery internship at Wynnewood, Oklahoma. There is no branded program name, no cohort structure, and no early-careers landing page. What CVR does publish is a detailed requisition that describes the work, the mentor structure, and the expected outcomes.
| Entity | Program | Status (September 2026) | Key details |
|---|---|---|---|
| CVR Energy (Wynnewood, OK) | Chemical Engineering Intern (Summer 2027) | 2 live requisitions | Hands-on refinery internship: preventive maintenance, troubleshooting, instrument repairs, HSSE training, assigned mentor, process-improvement project |
| CVR Energy (Coffeyville, KS) | No intern posting | Not open | 132,000 bpd refinery with six open process engineering roles but no intern requisition as of September 2026 |
| Icahn Enterprises L.P. (parent) | None | Does not exist | 37 employees, no careers site, no ATS. ielp.com is investor relations only |
| Icahn Automotive (AAMCO, Precision Tune) | Not findable | Unresolved | Careers link routes to a Pep Boys-branded board of store-level roles. Pep Boys was sold to Mavis on August 20, 2026 |
See the two live Chemical Engineering Intern requisitions at cvrenergy.com/Company/Careers. The CVR ADP board carries all 30 open positions. Set a job alert to catch any additional intern postings if CVR opens roles at Coffeyville or in other functions.
What Are the Eligibility Requirements?
CVR Energy's live Summer 2027 requisitions state a specific set of requirements. The hard gates are major and class year. Everything else is a preference.
• Major: Chemical Engineering only. The requisition says "College student with an engineering major in Chemical." No other engineering discipline is named.
• Class year: junior or senior. "Completed or entering into their Junior or Senior year at an accredited College or University."
• GPA: 3.0 preferred, not required. "Cumulative GPA of at least a 3.0 on a 4.0 scale, preferred." If you are at 2.8 with plant or co-op experience, the requisition gives you something else to lead with.
• Work authorization: US work authorization required. "The Company will not sponsor immigration or work visas." This is stated in the requisition body, not a footer.
• Preferred experience: "Previous work and/or coursework experience with manufacturing/process engineering preferred."
• Software: "Expert technical skills in Microsoft Office Suite." That is the only software named. No Aspen, no MATLAB, no Python.
Why Does CVR Only Hire Chemical Engineering Majors?
CVR Energy's Wynnewood refinery is a complex crude-oil refinery running coking, reforming and hydrotreating units. The intern requisition lists hands-on accountabilities including preventive maintenance, troubleshooting and instrument repairs, plant-operator shadowing, lock-out/tag-out participation and Instrument Protective Function observation. This is process-engineering work in a live petroleum refinery, not a desk-based simulation role, and CVR scopes it to chemical engineering students whose coursework covers reaction engineering, thermodynamics, mass transfer and process safety at the level the refinery operates. Mechanical and electrical engineers work at CVR in full-time roles, but the summer internship is scoped to ChemE.
What Skills Does Icahn Enterprises Look For, and How Do You Build Them?
CVR Energy's intern requisition is unusually explicit about what the work is and unusually silent about what tools you need. The entire software requirement is Microsoft Office Suite. No Aspen HYSYS, no PI/OSIsoft, no MATLAB, no Python, no SAP, no AutoCAD. The signal is real: CVR is hiring for plant presence, safety judgment and process-improvement instinct, not for simulation software proficiency. The accountabilities list preventive maintenance, troubleshooting and instrument repairs, plant-operator shadowing, laboratory-technician shadowing, Instrument Protective Function observation, lock-out/tag-out participation, and facilitating a meeting. A student expecting to sit at a desk running Aspen models all summer should recalibrate. This is hands-on refinery work.
How Is Demand for Refining & Process Engineering Interns Moving Right Now?
Petroleum refining intern hiring right now: September 2026
Across US refining and process engineering intern postings · aggregate market data, all employers
September 2026 is this tracker's baseline month. The refining intern market is small by design: operators hire for specific plants, not for cohort programs. CVR's two Wynnewood seats represent a real opportunity precisely because the supply of mid-continent refinery internships is structurally thin.

Build These Skills Before You Apply
And the skills CVR asks for map directly to remote Externships where you finish a real company project before the window closes.
| Skill (from real JDs) | JD evidence | Externship that builds it |
|---|---|---|
| Process improvement & operations | Manufacturing process optimization, preventive maintenance thinking, throughput analysis | Amazon Fulfillment Center Operational Strategy |
| Energy transition & renewable fuels | Renewable diesel context at Wynnewood, energy market analysis | EIC Energy Transition Venture Capital Market Research |
| Industrial safety & controls | HSSE, instrument protective functions, safety-instrumented systems thinking | Hydroficient IoT Cyber Defense |
How close is the overlap? The Amazon operations project builds the process-improvement evidence CVR's requisition explicitly prefers, the EIC energy transition externship gives a candidate something specific to say about renewable diesel at Wynnewood, and the Hydroficient project maps to the safety-instrumented systems and industrial controls that dominate CVR's intern accountabilities.
What Is the Icahn Enterprises Application and Interview Process Like?
CVR Energy publishes no description of its intern interview format. What can be pieced together from the requisition and the one public intern account:
1. Go to cvrenergy.com/Company/Careers, not ielp.com. Follow "Career Opportunities" to the ADP job board. ielp.com is investor relations with no careers section.
2. Apply to both requisitions (client IDs 1870 and 1871). They are two distinct seats at the same site with identical descriptions, not one posting listed twice.
3. Set a job alert on the CVR ADP board. With only 30 open requisitions company-wide, the board turns over slowly and an alert catches any additional intern postings.
4. Prepare for a safety-first conversation. The requisition names safety four separate ways: HSSE orientation, safety meetings, plant safety procedures, and lock-out/tag-out. If you have OSHA 10, a plant tour, a co-op, or even a lab-safety leadership role, lead with that.
5. Expect the sponsorship question to be final. "The Company will not sponsor immigration or work visas" is in the requisition body itself.
6. Offer and logistics. CVR publishes no housing or relocation support. Wynnewood is a small town 65 miles south of Oklahoma City. Plan to arrange your own accommodation.
The one public account of a CVR intern interview, from a Process Engineering Intern at Wynnewood in 2022, describes it as straightforward: "Everybody I worked with was incredibly kind and helpful, all the way up through management." CVR publishes no interview guide, no case-study format, and no behavioural-question bank.
What the Community Says
Reddit has no usable discussion of Icahn Enterprises or CVR Energy internships. The cards below draw on first-hand, dated, role-labelled Indeed reviews, which are the only public intern and engineer accounts that exist for CVR.
The only person who has publicly described interning at the Wynnewood refinery wrote in January 2022: "Everybody I worked with was incredibly kind and helpful, all the way up through management. Excellent place to learn and work." That is a single voice from the exact site now hiring, and it is positive from the shop floor to management.
A CVR engineer in Coffeyville, Kansas wrote in November 2025: "CVR runs a good operation in KS. Everyone works hard and is rewarded for it. Would recommend working here if you can settle down in the area, not much going in Cville." Wynnewood, 65 miles south of Oklahoma City, is smaller still, and CVR publishes no housing or relocation support for interns.
CVR Energy's Indeed management rating is 2.3 out of 5 across 73 reviews, the lowest category by a wide margin. The requisition's counterweight is specific and in writing: "The intern will be assigned a mentor to assist with personal goal setting for the internship." Ask who that mentor will be before you accept.
How Do You Stand Out for a Two-Seat Refinery Internship?
Three moves, all executable before September ends. First, understand that this is a plant internship, not a simulation internship. The requisition lists preventive maintenance, troubleshooting and instrument repairs, lock-out/tag-out participation and plant-operator shadowing. If you have any plant, co-op, or manufacturing exposure, that matters more than your Aspen coursework here. Second, lead with safety. The requisition names HSSE four separate ways, and the internship opens with safety orientation before any engineering work. OSHA 10, a safety officer role in a student org, or even a detailed answer about what lock-out/tag-out is and why it matters will set you apart. Third, know what Wynnewood actually makes. This is a 74,500 barrel-per-day complex refinery producing gasoline, diesel including renewable diesel, military jet fuel, solvents and asphalt. Naming renewable diesel in the interview shows you read the company rather than the job title. And be realistic about the setting: this is a small-town refinery internship with no published housing support, two seats, and a 2.3/5 management rating on Indeed. The one public intern account from this exact site is positive. Go in with your eyes open.
What Other Companies Should You Consider?
Two peer sets matter here: the holding-company structure that explains why Icahn Enterprises has no internship, and the mid-continent refiners that compete for the same chemical engineering students.

- Valero Energythe largest independent US refiner, with a much larger and more structured internship programGuide →

FAQ
Can I still apply for a summer 2026 Icahn Enterprises internship?
No, and there was never an Icahn Enterprises internship to apply to. IEP has 37 employees and no careers site. CVR Energy, the subsidiary where the internships exist, ran its Summer 2026 cycle already. The next open cycle is Summer 2027: two Chemical Engineering Intern requisitions are live at the Wynnewood, Oklahoma refinery as of September 2026.
Does Icahn Enterprises have an internship program?
No. Icahn Enterprises L.P. is a holding vehicle with 37 employees, no careers website, and no applicant tracking system. Its entire site at ielp.com is investor relations. The internships in the Icahn group are posted by its operating subsidiary CVR Energy.
Where do I apply for a CVR Energy internship?
Go to cvrenergy.com/Company/Careers and follow Career Opportunities to the ADP job board. Apply to both Chemical Engineering Intern (Summer 2027) requisitions, client IDs 1870 and 1871. They are two seats, not one posting listed twice.
How much do CVR Energy interns earn?
CVR Energy does not publish an intern pay figure, and neither requisition contains one. Indeed shows an estimated $24.72 per hour, but Indeed itself labels this Lowconfidence and says it is modeled from similar companies and nearby locations, not from CVR data. Ask the recruiter directly.
What GPA do I need for a CVR Energy internship?
The requisition states a 3.0 cumulative GPA on a 4.0 scale as preferred, not required. If you are below 3.0 but have manufacturing or process engineering experience, the requisition explicitly names that as a preferred qualification too.
Can international students apply?
No. The requisition states in its body: "The Company will not sponsor immigration or work visas." US work authorization on a full-time basis is required.
What happened to Pep Boys? I thought Icahn owned it.
Mavis Tire Express completed its acquisition of Pep Boys from Icahn Automotive Group for approximately $700 million in cash on August 20, 2026. Icahn Enterprises retained the owned real estate plus the AAMCO Transmissions and Precision Tune Auto Care businesses. Any guide routing you to Pep Boys for an Icahn internship is out of date.
What would I actually do as a CVR Energy intern?
Refinery work. The requisition lists safety and team meetings, preventive maintenance, troubleshooting and instrument repairs, shadowing plant operators and a laboratory technician, observing Instrument Protective Function testing, possibly operating equipment, and possibly participating in lock-out/tag-out. You are assigned a mentor for goal-setting, and one graded expected result is to facilitate a meeting.
CVR Energy's two Wynnewood seats are the entire Icahn Enterprises internship. With no deadline and only two openings, the window's close is invisible. Build the process-improvement and safety evidence before you apply: a remote Externship turns "interested in refining" into a finished project a CVR application can point at.
