  • You will ensure that the remote ground receiver subsystems are supportable, delivering reporting, logging and tooling to quickly diagnose issues from the central control facility.
  • You will lead the development of the control and monitoring software, mentoring and coaching software engineering staff to build their understanding of distributed systems engineering. You will be working in close collaboration with the mission control and reporting team to ensure technical alignment across the subsystems.
  • You will work with 3rd party suppliers, providing feedback on delivered components and working with the supplier to resolve issues.

What we’re looking for:


  • Multiple project experience in design and development of highly resilient control software.
  • Demonstrated experience of networking, secure communication and hardware control and reporting.
