KO2’s client is a long-established UK manufacturer of advanced scientific instruments. Universities, research centres and industry around the world use them to study materials at the nanoscale.

Their systems support research in quantum computing, dark matter and new materials, so your software will be used in cutting-edge science. The business is growing, has a stable future, and still designs and manufactures everything in the UK.

This is a new role created to grow the software team. As Senior Software Engineer, you’ll be a technical leader in an established backend team. You’ll help the Software Manager guide the team and develop less experienced engineers.

You’ll be the main technical authority for the backend software that controls the company’s instruments. It’s a Modern C++ (C++17) application running on a Debian Linux industrial PC that acts as a local edge server. It coordinates communication with pumps, valves, pressure gauges, temperature sensors and other devices, so the system reaches the state the user has asked for.
