 * Strong communication, problem-solving and stakeholder-management skills
 * The confidence to provide constructive technical feedback and challenge requirements appropriately

Experience with any of the following would be beneficial:

 * Telecommunications or mission-critical systems
 * TETRA, LTE or other wireless communication technologies
 * Protocol, RF or network testing
 * TCP/IP, UDP, serial or Bluetooth interfaces
 * API and backend testing
 * Python, Java or another automation language

You don't necessarily need direct TETRA experience. Candidates from embedded electronics, telecoms, defence, automotive, networking, IoT or other safety- or mission-critical product environments are encouraged to apply.

If you're an experienced Test Engineer who enjoys working with complex physical products and not simply web applications and wants greater ownership of quality across the full development lifecycle, apply now for further information.
