If you are great at what you do, enjoy working in a startup environment, and are passionate about developing electrical systems for leading‑edge communications satellites, we would like to hear from you.

In this position, you will be responsible for designing and delivering the C&DH subsystem for cutting‑edge communication satellites. You will own the C&DH subsystem block diagram (in alignment with electrical architects), subsystem‑level analysis, make‑buy trades, trade studies for “buy” items, technical vendor interactions, subsystem Design Verification Testing (DVT), hardware delivery, and on‑orbit support.

As a Satellite team member, you will work on a small team to develop satellites and put them in orbit. You will be a key point of contact for satellite software, mechanical, and AI&T teams. You will provide creative solutions to complex problems to push the boundaries of spacecraft design.

Job Duties And Responsibilities

• Perform technical definition, implementation, and verification of satellite avionics systems
• Define and maintain C&DH subsystem architecture and interfaces
• Conduct make/buy trades
• Represent C&DH by interfacing with the satellite systems, mechanical, software, and AI&T teams
• Collaborate on in‑house solutions to advance satellite performance and manufacturability at scale
• Make effective decisions given limited input and analysis while driving the team to produce and iterate hardware
• Design and execute box‑level and subsystem‑level test plans for design verification testing, qualification testing, and/or acceptance testing
• Prepare and deliver technical communications to company leadership and executives
• Deliver reliable, performant space avionics system for spaceflight missions
