Hybrid Real-Time Software Engineer (C/C++/C#) in Surrey

About ipTEST: ipTEST is a growing company in an exciting high technology area at the forefront of new developments powering the green revolution. We are a dedicated, engineering‑based organisation with the skills to meet the demanding needs of our growing customer base of semiconductor device manufacturers around the world. We develop solutions for testing challenging new green power technologies such as GaN and SiC, as well as for the latest generation of MOSFETs, IGBT’s, diodes, SCR’s and bipolars. ipTEST is headquartered in the UK, with applications and support facilities in Malaysia and Japan. We have a track record of investing in our people and work hard to ensure that all our staff are well informed, well trained and well‑motivated to be completely responsive to our customer needs.

About the role: ipTEST builds the software behind semiconductor test equipment, and our software is central to everything we ship. Our main product is controlled by our native desktop application, a mature, real‑time software solution with a substantial customer base.

Someone who is comfortable with the challenge of working with an established codebase, is excited by modernisation, who cares about doing things properly and wants to be part of shaping where a product goes next. The role is based in Guildford. Mostly on‑site, but we're relaxed about a couple of days from home once you're up and running. If that sounds like the kind of role you've been looking for, we'd love to talk.
