Assistant Project Manager (PMO) in London

What if you could shape a career as unique as you? At WSP, you can always find opportunities to grow and do what matters to you. Make the most of our global reach to discover new challenges and chances to work with diverse, talented individuals who will help you expand your horizons.

A little more about your role… We’re excited to be growing our Environmental Project Management team and are looking for several Assistant Project Managers to join us in our PMO team. In this role, you’ll play a key part in supporting the delivery of multi-disciplinary environmental projects, working closely with Project Managers and Technical Leads to keep projects safe, on track and within budget. You’ll gain exposure to a diverse portfolio of work across the UK, spanning both public and private sector clients. It’s a brilliant opportunity to build your core project management foundations, learning how to apply structured processes and best practice in a real project environment. You’ll get hands‑on experience across the full lifecycle, helping to troubleshoot challenges as they arise, and build the skills and confidence to progress into an Environmental Project Manager role over time.

So, if you enjoy getting into the detail, bringing order to complexity and don’t mind a spreadsheet or two (or twenty), you’ll feel right at home here. You’ll be joining a high‑performing, environmentally focused Project Management team known for its collaborative, supportive culture and strong focus on development. As we continue to grow, we’re committed to giving you the space, support and opportunities to learn, progress and build a rewarding career.
