Architecture Internship 2027 – Mott MacDonald

Mott MacDonald is hiring for its Mott MacDonald architecture internship in Iselin, New Jersey, part of Prelaunch, the firm’s structured summer internship programme. The placement runs from 14 June to 20 August 2027 and pays between $18 and $35 an hour, depending on location, education, experience and skills. The application window closes on 30 November 2026, so there are only a few weeks left to apply. The role sits in the firm’s Buildings market under the Architecture discipline (job reference 17019).

Mott MacDonald, a collaborative engineering consultancy, says engineering is about shaping an inclusive, resilient and sustainable future, not only solving problems. It is expanding across the US and Canada and works as a trusted consultant to clients facing complex challenges.

The Prelaunch programme

Prelaunch is a three-month development journey meant to lay the foundations for a career at the firm. Interns work beside experienced consultants, project managers, specialists, mentors and peers, and learn to think like consultants while doing meaningful work. Depending on the project, tasks may include:

• Designing solutions and refining technical designs and documentation
• Site inspections and monitoring
• Joining project and client meetings
• Analysing reports and specifications
• Exploring project and client management, and using digital tools
• Working towards sustainable outcomes
• Meeting peers through the Early Career Professionals Network

Who can apply

• Students working towards a bachelor’s or master’s degree in architecture or a related field
• Proven interest in the field through earlier internships, volunteering or memberships
• Creative thinking with a methodical, pragmatic approach to problems
• Confident communication and presentation skills, and a collaborative attitude
• Authorisation to work for any employer in the US: the firm cannot sponsor visas

The internship follows the firm’s hybrid policy, which centres on the office with at least three days a week on site, so applicants must be able to commute reliably to Iselin. Eligible interns may join the 401(k) retirement plan, and the programme includes mentoring, learning and development, and Employee Resource Groups.
