Simulation Engine EngineerUp to £110,000

About the Role

Vsim builds the simulation and learning stack robots train inside. The engine is the core of it. vLab, their GPU-accelerated physics simulation, feeds vLearn, their robot learning framework, and vBot, which runs models in real time on edge hardware. You'll lead development of that core simulation and engine infrastructure, hands-on, alongside two founders who still write engine code every day.

This is a senior IC seat, not a management one. The on-site engineering team in Cambridge is early-career, and they need a senior engineer in the room. You'll build, review, unblock and mentor. There's a path into formal leadership later if you want it. The lab also has humanoid and quadruped robots, so your work can reach real hardware.

What They're Looking For

• You write exceptional modern C++ and have shipped performance-critical systems where speed is the product.
• You've built or worked deep inside a game engine or simulation engine, or a comparably complex low-level system close to the hardware.
• You're senior, and you've grown less experienced engineers through code review, pairing and clear task-setting.
• You listen. You work well with hands-on founders, debate ideas openly and don't need to go it alone.
• You want to be on site with the team in Cambridge every day, not dialling in.

About Vsim

Vsim builds GPU physics simulation and training infrastructure for robotics. It was founded in 2022 by two engineers who each spent over a decade building physics engines on Nvidia's simulation team. VC-backed with a long runway, it's a team of around 11 in Cambridge, UK, most of them engineers.
