The role

Aimsun is growing its UK team and is looking for a Senior Project Manager / Programme Delivery Manager to lead the delivery of complex, multi-disciplinary projects for our clients. You will be the main point of contact for clients and stakeholders, owning scope, programme, budget and quality from kick-off to final sign-off.

Our projects bring together transport planning, transport modelling, data science and software delivery, ranging from strategic and operational models to data platforms and real-time Digital Twin solutions for traffic management. Our clients are mostly public-sector bodies, such as national, regional and city transport authorities, alongside a growing base of private-sector clients.

You will lead teams of modellers, transport planners, data scientists and software engineers to deliver them. You don't need to be an expert in every discipline. We're looking for someone who has a strong record of delivering complex technical projects, understands enough of the detail to ask the right questions, and gets satisfaction from bringing work in on time and on budget.

You will be part of a European delivery team working across Aimsun's entities in Barcelona, Paris and London. Projects are delivered by colleagues from all three offices, so you will coordinate people, workstreams and clients across borders and time zones.
