Senior Robotics Software Engineer C++
London EC1V - Hybrid
Build software that powers unmanned systems already deployed in the real world.
At sees.ai, we’ve developed a system that is already being used to inspect critical national infrastructure - operating in live environments, not simulations.
Now, following a major contract with National Grid and recent investment, we’re scaling that system into a robust, production ready platform.
We’re looking for a Senior C++ Software Engineer to help take a working system and evolve it into something reliable, scalable, and ready for wider deployment.
The Role
This is a systems focused engineering role, not a narrow backend position.
You’ll work across the core software stack that powers our unmanned systems - contributing to everything from flight control and mission systems, through to simulation, connectivity, and operator interfaces.
You’ll be working on software that directly impacts how the system behaves in the field, with a short feedback loop between development and real world use.
This is an environment where:
You’ll balance hands on development and debugging with longer term architectural thinking as the platform evolves.
