About the company

A high-growth engineering consultancy is expanding its software team as it scales significantly over the next 12 to 18 months. This is not a maintenance role. This is an opportunity to build technically complex systems from scratch, often at the intersection of software and hardware, across cutting-edge sectors including biotech, quantum computing, heavy industry and government-backed R&D.
