Ground Systems Engineer

Zachary Piper Solutions is seeking a Ground Systems Integration Engineer (Active TS/SCI required) to join Quindar, the startup founded by the ex-OneWeb team that operated one of the largest constellations ever built. This is a true builder role: every week you’ll take a new satellite’s ICD, translate it into working command & telemetry inside Quindar’s cloud-native platform, and get it talking flawlessly over CCSDS, CSP, CFDP, XTCE. Think low-level protocol parsing, real-time debugging with simulators and hardware-in-the-loop, and turning raw spacecraft frames into something operators can use with a single click.

Job overview:

• Write the code (mostly Python & C ) that connects flight software to Quindar’s mission management platform
• Build command dictionaries, telemetry parsers, and automation scripts from vendor ICDs
• Debug timing issues, dropped packets, encryption handshakes (AES-256, etc.), and weird edge cases at 2 a.m. when the bird is on-orbit
• Work directly with spacecraft teams and Quindar’s platform engineers to proliferate solutions across entire constellations
  
  

Requirements

• Active TS/SCI clearance
• 3–8 years doing satellite C2, ground software integration, or hardware-software problems
• Strong Python and/or C (Rust ideal)
• Hands-on experience with CCSDS, CSP, CFDP, XTCE, MIB, COSMOS/OpenC3, or equivalent
• Willing to be at the Los Angeles, CA sit 2–3 days per week (rest is remote)
  
  

Compensation:

• Compensation: $110,000 – $170,000 equity full benefits
• Unlimited PTO (with 15 days mandatory)
