About this role
Astranis operates satellites in high orbit serving government and enterprise customers with demanding requirements around security and uptime. As a Senior Software Engineer on the Flight Software team, you would own critical pieces of the software that commands and monitors these spacecraft, working in C++ on flight computers and control board firmware. The role spans architecture decisions, implementation, testing infrastructure, and mentoring junior engineers, with your work directly supporting both commercial contracts and US Government programs.
This position suits someone with 5+ years of embedded systems experience who has shipped production software and understands the constraints of reliable, high-availability systems. You should be comfortable with communication protocols, design patterns, and collaborative development across hardware and ground control teams. Experience with real-time operating systems like VxWorks, Linux, or FreeRTOS, or background in safety-critical domains, would strengthen your candidacy, though the core requirement is solid modern C/C++ skills and a track record of delivering complex projects incrementally.
The role is based in Astranis's San Francisco headquarters and requires in-office work. Compensation ranges from $200,000 to $280,000 base salary, plus equity, comprehensive healthcare, 401(k), and flexible PTO. U.S. citizenship or lawful permanent residency is required due to export regulations governing space technology.
