We are looking for an Embedded Software Research Engineer to join our Thales Research & Technology (TRT) team in Reading.

No two projects are the same, offering exposure to a diverse range of technical challenges and emerging technologies. If you're motivated by solving complex engineering problems, learning from experienced research engineers, and seeing your ideas shape future defence and security solutions, this role offers an exceptional environment to develop your expertise and make a meaningful impact.
