What Is a MasTec Internship?

A MasTec internship is a paid, 10–14 week summer placement that puts engineering and construction management students into real roles on active infrastructure projects at a Fortune 500 company with $14.3 billion in annual revenue. Founded in 1994 by the Mas family (roots trace to 1929), MasTec operates across four business segments: Communications ($3.3B), Clean Energy & Infrastructure ($4.7B), Power Delivery ($4.2B), and Pipeline Infrastructure ($2.1B). The company is NMSDC-certified as a Minority-Controlled Company and employs approximately 36,000 professionals from 300+ offices across the US, Mexico, and Canada. Interns work in both office and field settings, assisting with estimating, schedule planning, project controls, and project reporting under MasTec’s Zero Injury safety principles. CEO Jose Mas has led the company since 2007, and the Mas family holds approximately 21% ownership.

When Do MasTec Internship Applications Open for 2027–2028?

MasTec operates through multiple subsidiaries, each with its own career portal and posting schedule, so there is no single application deadline. Based on prior-cycle patterns, summer internship postings typically begin appearing in the fall for the following summer, with additional roles posted on a rolling basis through the spring. The company runs both summer and fall internship and co-op programs. For summer 2027, expect postings to appear starting around September–October 2026 on the various subsidiary career sites. MasTec’s decentralized structure means you should monitor multiple portals: careers.mastec.com, careers.wanzek.com (MasTec Civil), and careers.mastecindustrial.com.

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

MasTec’s decentralized subsidiary structure means intern roles post independently and fill independently. There is no company-wide application deadline or centralized class that fills all at once. Each subsidiary fills its intern positions as soon as qualified candidates apply. If you wait until spring 2027 to look, the MasTec Civil highway project in Florida or the Cash Construction utility job in Texas may already have its intern locked in. The company’s 33% year-over-year backlog growth to $19 billion and the July 2026 acquisition of The Superior Group ($1.65 billion, data center electrical infrastructure) signal sustained hiring demand, but individual intern seats are scarce relative to the 36,000-person workforce. Early application plus shown field-readiness is the formula.

Which MasTec Internship Programs Should You Target?

MasTec runs internship programs across at least four subsidiaries, each focused on a different infrastructure sector. Which one to target depends on your engineering interest and willingness to relocate to the project site.

See all openings across MasTec subsidiaries at mastec.com/careers, MasTec Civil careers, and MasTec Industrial careers. Each subsidiary posts independently, so check all three portals.

What Are the Eligibility Requirements?

MasTec’s internship JDs are relatively consistent across subsidiaries. Based on multiple reviewed postings from the Summer/Fall 2026 cycle:

• Enrollment: currently enrolled in a Bachelor’s program in Engineering, Construction Management, or a related field. JDs describe candidates as “ideally college students in Engineering or Construction Management degree.”

• GPA: no minimum GPA stated in any reviewed MasTec intern JD. The company does not publish a GPA threshold.

• Work authorization: not explicitly addressed in intern-specific postings. MasTec is an Equal Employment Opportunity Employer.

• Pre-employment screening: positions may be subject to background check and drug testing. MasTec’s Zero Injury safety principles are emphasized across all postings.

Does MasTec Require a Specific GPA for Interns?

No published GPA requirement exists. MasTec’s intern JDs focus on enrollment status, relevant major (engineering or construction management), communication skills, and Microsoft Office proficiency. The company’s emphasis is on field-readiness and willingness to work in construction environments rather than academic metrics. If you have a lower GPA but can point to relevant field experience, safety certifications (OSHA 10 or OSHA 30), or construction coursework, those carry weight.

What Skills Does MasTec Look For, and How Do You Build Them?

MasTec’s intern JDs are soft-skill-heavy compared to tech or finance internships. Hard technical skills like CAD, Primavera P6, or heavy equipment operation are not mentioned in the postings, even though they would be valued in practice. The JDs are framed as learn-on-the-job opportunities where Microsoft Office proficiency, communication, and attention to detail are the baseline. What this tells you is that MasTec hires for attitude, field-readiness, and relevant academic background, then trains the technical skills on-site.

Build These Skills Before You Apply

And every skill in the chart maps to a remote Externship where you finish a real company project before the window opens.

How close is the overlap? The Amazon Ops project builds the operational strategy and process optimization skills every MasTec construction intern JD asks for, the EIC Energy externship develops the energy infrastructure context that MasTec’s Clean Energy & Infrastructure and Power Delivery segments operate in, and the Breaking Games project develops the data analysis and reporting skills that project controls work requires.

What Is the MasTec Application and Interview Process Like?

MasTec’s interview process is generally fast and straightforward, consistent with the construction industry norm. Based on Glassdoor data (105 company-wide interviews) and intern JD analysis:

1. Apply at mastec.com/careers or the relevant subsidiary portal with a tailored resume. Highlight engineering coursework, any field experience (even summer labor or surveying), safety certifications, and willingness to relocate to project sites.

2. Recruiter phone screen (week 1). A 15–30 minute call covering your background, experience, motivation, and salary expectations. Expect questions about why construction and why MasTec specifically.

3. Hiring manager interview (weeks 1–2). An in-person or virtual interview with the project or operations manager. Behavioral questions about field experience, technical knowledge, construction processes, and safety awareness.

4. Some roles include a panel interview with multiple team members, combining behavioral and technical questions about procurement, sourcing strategies, and project management fundamentals.

5. Offer and onboarding. The process is fast: one Glassdoor candidate reported the entire process took one week. Housing allowance logistics confirmed for students relocating to project areas.

MasTec’s construction intern interviews do not include coding assessments, HireVue recordings, or standardized online tests. The process is conversational and behavioral, with an emphasis on field-readiness, safety awareness, and genuine interest in construction. Employee referrals can accelerate the process. Our HireVue question guide with a free AI mock tool covers the same behavioral-question pressure and format.

What the Community Says

MasTec is a recognized name in construction management and engineering forums. Here is what the community says about working there.

How Do You Stand Out at a Decentralized Infrastructure Giant?

Three moves, all executable before fall 2026. First, get OSHA 10 or OSHA 30 certified before applying. MasTec’s Zero Injury safety culture is emphasized in every JD and on the corporate site, and walking in with an OSHA safety certification signals you understand the construction industry’s top priority. Second, learn the four business segments and speak to your preferred one. MasTec operates Communications, Clean Energy & Infrastructure, Power Delivery, and Pipeline Infrastructure. Showing you know the difference between a CE&I solar farm project and a Power Delivery transmission line project demonstrates genuine interest. Third, reference MasTec’s $19B backlog and the July 2026 Superior Group acquisition ($1.65B, data center electrical infrastructure). Tying your skills to data center infrastructure, renewable energy, or grid modernization connects your application to where the company is investing. And bring a project estimating or scheduling example from your coursework. Both the MasTec Civil and Cash Construction JDs list estimating, schedule planning, and project controls as core intern responsibilities.

What Other Companies Should You Consider?

MasTec’s peer set spans specialty contractors and large-scale EPC firms, all competing for the same construction management and engineering intern talent.
