AECOM Internship 2027–2028: Programs, Deadlines & How to Apply

Last updated: August 2026

AECOM had exactly four distinct US intern requisitions live on its own job board on August 10, 2026, across a firm of 50,000+ people that ENR ranks #2 among all US design firms. That's not a small class; it's a different model. AECOM doesn't run one big summer window. It posts intern requisitions office by office, year round, with a fall cluster and a spring tail. The typical lead time runs 1 to 9 months, and late-cycle reqs were still closing in May and June 2026 for that summer's class.

So for summer 2027, expect the first postings in fall 2026.

Quick Facts

The one number: there's no application deadline because there's no single application window. AECOM posts intern reqs continuously, office by office, with a fall-weighted cluster. Your job is to set alerts and apply the week a specific req appears.

Externships are short, remote programs where you finish a real project with a real company. The Healthcare Operations Consulting Externship builds the multidisciplinary project and stakeholder communication skills AECOM's JDs ask for, and the Hydroficient IoT Cyber Defense Externship adds an infrastructure-adjacent systems project to your resume.

What Is an AECOM Internship?

An AECOM internship is a paid, office-specific placement at a $16.1 billion infrastructure consulting firm (NYSE: ACM, Fortune 500) that designs and manages projects across water, transportation, environment, energy and buildings. The firm consulted on One World Trade Center, the Intuit Dome and Mercedes-Benz Stadium.

And Glassdoor's best-rated job titles at AECOM are Engineering Intern, Intern and Intern - Hourly. Pay ranges run $17 to $35 an hour across 18 real 2025–2026 postings, with a median midpoint near $23.70.

When Do AECOM Internship Applications Open for 2027–2028?

AECOM is the anti-deadline company. It says so itself: it looks for intern talent 'year round', with 'many of our roles open in the fall.' The 2026-cycle data shows reqs still closing in May and June 2026 for that summer's class.

So what does that mean for summer 2027? Think of it as a 9-month window: fall 2026 through late spring 2027, with each individual req lasting days to weeks.

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

AECOM answers the deadline question on its own careers page: 'We continuously are looking for talent for our intern and graduate roles, year round.' Prosple's listings add that AECOM jobs 'may close before the stated closing date.' With only four live intern reqs across a 50,000-person firm on any given day, each posting is a small window.

So the firm's own advice to apply the moment you see one is the closest thing AECOM has to a deadline.

Which AECOM Internship Programs Should You Target?

AECOM doesn't run five named tracks with a brochure. It posts office-level requisitions that span the firm's engineering disciplines. Here's what real 2025–2026 postings looked like — and what the next cycle's reqs will likely mirror.

The full list shifts with each cycle. And AECOM runs the HBCU Summer Design Fellowship (8–9 weeks in Detroit, up to four fellows, architecture/urban planning/interior design) and a Graduate Development Program for entry-level hires.

What Are the Eligibility Requirements?

AECOM's eligibility rules change by requisition, so read each posting rather than assuming one bar:

• Enrollment: must be pursuing a bachelor's or graduate degree. Recent graduates heading to a master's are explicitly welcome, which is an unusual policy worth noting.

• Years of study: varies by req. Some ask for 1 year completed, others for 2 or 3. A sophomore is eligible for some AECOM reqs and not others.

• Driver's license: required on 5 of 11 JDs reviewed, with a Motor Vehicle Records check as a condition of employment. If you don't drive, that narrows your options.

• Sponsorship: not available on most reqs ('sponsorship for US employment authorization isn't available for this position now or in the future'). Two civil and dams reqs require US citizenship outright.

• Relocation: not offered on 6 of 11 reqs. Apply to the office you can already live near.

Does AECOM Have a GPA Cutoff?

No. Only one of eleven AECOM intern JDs names a GPA at all — the Dam Safety Engineering intern, which lists 'a GPA of 3.0 or higher' under preferred qualifications, not minimum. The real gates are completed coursework (1, 2 or 3 years depending on the req), and on nearly half the postings, a valid driver's license with a clean MVR.

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

Eleven real AECOM US intern JDs tell a clear story: this is a tools-and-communication company. Microsoft Office and Excel appear in 9 of 11. AutoCAD shows up in 7. But communication and engineering design calculations tie AutoCAD at 7 of 11, which means AECOM hires interns to explain their work, not just produce drawings.

And here's the gap between AECOM and the aggregated market data: Civil 3D and MicroStation appear in only about 18% of AECOM's intern postings, not the 70% the raw market numbers suggest (that's one employer's boilerplate inflating the count).

And every bar in the chart maps to a remote Externship that ends in a finished company project.

How close is the overlap? The Healthcare Operations Consulting deliverable is a stakeholder-ready operational analysis, exactly the communication-plus-analysis profile that appears in 7 of AECOM's 11 intern JDs.

What Is the AECOM Application and Interview Process Like?

AECOM's process is interview-led, not OA-gated. There's no coding assessment or standardized online test.

1. Join the Talent Network and set alerts for your target offices. For a rolling employer, this is the step that matters most.

2. Search AECOM's board filtered to offices you can commute to. Relocation usually isn't offered, so apply the week the req appears; postings carry a warning they may close early.

3. Recruiter / phone screen with AECOM's Early Careers team on background, office fit, work authorization and driver's license status.

4. Technical hiring-team interview. In person or video, roughly 30 minutes, with the hiring manager and project manager. Expect questions about coursework, projects, software you've actually used and why this discipline. Glassdoor rates difficulty at 2.6 out of 5.

5. Post-offer checks: background check, MVR review on driver's-license reqs, and a pre-employment substance-abuse test on some postings. All new hires attend an in-person Day 1 onboarding.

Glassdoor's median: 33 days from application to hire for AECOM intern roles (n=34).

And don't overlook the second door: 35% of AECOM intern interviews came through campus recruiting, not the online application.

What Students on Reddit Say

Three threads from r/civilengineering, paraphrased.

How Do You Stand Out When AECOM Posts Only a Handful of Reqs at a Time?

Three moves, starting with the alert. Join the Talent Network right now and set office-specific alerts, because AECOM's postings appear without warning and close fast — four live intern reqs across 50,000 employees is a typical day. Second, search wider than 'civil engineering intern.' AECOM's own intern titles include 'Engineering Intern,' 'Traction Power Intern,' 'Bridge Inspector Co-Op' and 'Digital Technology Specialist Intern,' and market data shows half the addressable civil-engineering intern jobs sit under titles like 'field engineer intern' and 'project engineer intern.' Third, make the interview easy for them. AECOM's process is interview-led with a 2.6/5 difficulty rating and 79% positive experience on Glassdoor. Walk in ready to talk about your coursework, the CAD software you've actually used, and one project where you turned data into a deliverable.

What Other Companies Should You Consider?

AECOM's peer group is the ENR Top 10 design firms, where summer intern reqs compete for the same civil and structural engineering students.

FAQ

Can I still apply for a summer 2026 AECOM internship?

No. Summer 2026 has already happened. AECOM's last summer-2026 US intern postings closed between 8 May and 15 June 2026. What's open right now (August 2026) is a handful of immediate-start and fall-2026 co-op reqs.

So for summer 2027, expect postings to start appearing in fall 2026 and to keep appearing through spring 2027.

When do AECOM internship applications open for summer 2027?

There's no single date. AECOM says it looks for intern talent 'year round' and that 'many of our roles open in the fall,' posting office by office rather than in one national window. Expect the first summer-2027 reqs in September through December 2026, with more appearing continuously through spring 2027.

Is the AECOM internship rolling?

More than rolling: it's continuous. Each office posts its own requisition when it needs an intern, and postings carry a warning they may close before the stated closing date. The practical move is to join AECOM's Talent Network, set alerts for your target offices, and apply the week a req appears.

How much do AECOM interns get paid?

AECOM publishes a pay range on every US posting. Across 18 real 2025–2026 intern reqs, ranges ran from $17 to $35 an hour, with a median posted midpoint near $23.70.

And civil and transportation intern reqs cluster around $20 to $28 an hour, about 19% above the $19.85 national average for civil-engineering interns.

Does AECOM require a minimum GPA?

No stated minimum. Only one of eleven AECOM intern JDs reviewed named a GPA at all: the Dam Safety Engineering req, which listed 'a GPA of 3.0 or higher' under preferred, not minimum, qualifications.

But completed years of study matter more: reqs ask for one, two or three years finished depending on the role.

What skills does AECOM look for in interns?

Across eleven AECOM intern JDs, Microsoft Office and Excel appeared in 9 of 11, AutoCAD in 7, written and verbal communication in 7, and engineering design calculations in 7.

But Civil 3D and MicroStation show up in only about 18% of AECOM's intern postings, far below what aggregated job-board data suggests.

What is the AECOM intern interview like?

There's no coding assessment. AECOM says candidates 'can expect to have an in person or video interview with our technical hiring teams.' Glassdoor's 47 AECOM intern interview reports rate difficulty at 2.6 out of 5 and the experience 79% positive, with a median of 33 days from application to hire.

Do AECOM interns get return offers?

AECOM doesn't publish a conversion rate. Its JDs state that 'successful interns may be eligible to return for additional internships,' and graduate hires enter a structured Graduate Development Program.

And community reports on Reddit describe students interning at AECOM across two or three consecutive cycles rather than converting in one shot.

AECOM doesn't give you a deadline to circle. It gives you a rolling board that updates office by office, fall through spring. The highest-value thing you can do today is join the Talent Network, set alerts for your target offices, and spend the wait on proof: a remote Externship turns 'I've taken the classes' into a finished project the week-one application can point at.
