Mott MacDonald runs a rolling, office-level internship model with no single application window. Summer-2027 reqs are already live. Pay ranges from $18 to $35 per hour depending on discipline and location, and the employee-owned culture gives interns direct exposure to staff who hold a stake in the firm’s success.
While you wait for the right Mott MacDonald req to appear, you can build relevant skills through an Externship — a short, remote professional experience program (typically 8 weeks, 5–10 hrs/week). The Center for Improving Youth Justice Data Visualization Externship builds the data-visualization and reporting skills that engineering consultancies list on every intern JD, and the Amazon Fulfillment Center Operational Strategy Externship develops the operational analytics mindset that translates directly to infrastructure project work.

What Is a Mott MacDonald Internship?
Mott MacDonald’s US internship program places students in discipline-specific roles at individual offices, working on live infrastructure projects in transport, water, energy, buildings, and environment. The company holds a 3.9/5.0 employer rating on Indeed (approximately 700 reviews) and has earned Glassdoor Best Places to Work recognition in 2023, 2024, and 2026. What makes the program distinctive is employee ownership: Mott MacDonald is one of the world’s largest wholly employee-owned companies, so interns work alongside staff who have a direct financial stake in the firm’s long-term success rather than quarterly earnings targets. The company also supports professional certification (PE, Peng, Licensed Surveyor) for early-career staff, signaling genuine investment in intern-to-career development.

What Are the Eligibility Requirements?
Mott MacDonald’s intern eligibility requirements vary by posting, but several consistent patterns appear across the listings reviewed.
• Enrollment: Must be pursuing a bachelor’s or graduate degree in a relevant engineering or science discipline (civil engineering, geotechnical engineering, geology, GIS, or computer science depending on the track).
• Class year: Typically completion of sophomore or junior year for technical internships.
• Work authorization: Not explicitly stated on all listings; confirm visa sponsorship availability for each specific posting.
• Driver’s license: Likely required for field-oriented roles involving site inspections and project visits, as is standard across AEC consultancies.
• Application limit: You may submit up to 25 applications within any 12-month period through Mott MacDonald’s Connect People portal.
Does Mott MacDonald Have a GPA Cutoff for Interns?
No minimum GPA appears in any of the Mott MacDonald intern listings reviewed. The company’s application FAQ does not mention a GPA threshold either. This is consistent with most large AEC consultancies, which weight relevant coursework, project experience, and technical skills more heavily than cumulative GPA. That said, a strong academic record never hurts, and some offices may use it as a screening factor in competitive cycles.
What Skills Does Mott MacDonald Look For, and How Do You Build Them?
Across the civil, geotechnical, geology, GIS, and digital delivery intern postings, Mott MacDonald’s JDs cluster around a consistent set of technical and professional skills. AutoCAD and Civil 3D appear in every engineering-track listing, while GIS and ArcGIS anchor the spatial analysis roles. Communication and technical writing show up across all tracks because consulting-model firms produce reports as their primary deliverable. The employee-owned culture also places a premium on teamwork and cross-disciplinary collaboration.

What the Community Says
Mott MacDonald holds a 3.9/5 rating on Indeed from roughly 700 reviews. Here is what employees and interns are saying about the experience.
The overall rating sits at 3.9 out of 5 across about 700 reviews, with work-life balance scoring 3.8 and culture at 3.7. Reviewers consistently highlight time and location flexibility and an inclusive work environment as top pros. For an employee-owned firm with 19,500 staff in 150 countries, those numbers suggest a culture that genuinely walks the talk on flexibility.
Pay and benefits land at 3.5 out of 5, and 65% of surveyed employees believe they are paid fairly. The Indeed average for interns comes in at $23.27 per hour, roughly 15% above the national average. Multiple reviewers note that the company invests in early career professionals through its ECPs network, which signals genuine retention intent rather than just a summer placeholder.
One intern review flagged that they had to keep asking for tasks and felt undervalued, with strict timesheet guidelines eating into billable learning time. On the flip side, general positive themes point to an inclusive environment that invests in ECPs. The takeaway: your experience depends heavily on the specific office and team, which is consistent with how large AEC consultancies operate.
How Do You Stand Out at Mott MacDonald?
Lead with the employee-ownership angle. Mott MacDonald is one of the world’s largest wholly employee-owned companies, and interviewers notice when a candidate understands what that means: long-term decision-making, shared profit, and a culture that prizes collaboration over internal competition. Reference a specific Mott MacDonald project (the Channel Tunnel, Delhi Metro, or Heathrow Terminal 5) and explain what you would learn from it, because this firm values cross-sector curiosity across transport, energy, water, and buildings. Finally, articulate your professional certification plan (PE, Peng, or Project Management) and ask how Mott MacDonald’s mentorship program supports it. This signals you are thinking about a career, not just a summer placement, which resonates at a firm built on long-term retention and ownership.
