An exciting opportunity has arisen at Secure Thingz, an IAR Systems group company, working on multiple products related to our Embedded Trust solutions. We are looking for a flexible, ambitious and deadline focused team player to join us as a Senior Embedded Software Developer.  This will specifically suit someone experienced working at the “Bare Metal” level on Microcontroller devices with performance and memory constraints who also are knowledgeable on kernels and low-level operating system implementation.


You will be developing embedded software, porting software to new devices and developing and running unit test cases. You will be working with other development team members, the architecture team and silicon partners.  This will require developing solutions which work on a range of devices with advanced technologies alongside our global silicon vendor partners.

Required Skills:

  • 5 or more years prior experience with embedded system software development.
  • Excellent knowledge of low-level embedded C at a bare metal driver level.
  • Experience in developing and optimising software:
