Senior Software Engineer, Vehicle Software Infrastructure

Senior Software Engineer, Vehicle Software Infrastructure

Join us as a Senior Software Engineer, Vehicle Software Infrastructure at Relativity Space, where we are building rockets to serve today’s needs and tomorrow’s breakthroughs. Your work will help shape the foundation of Terran R’s software stack, influencing performance, reliability, and flight success.

Relativity Space is on a mission to better connect humanity to space. The Vehicle Software team develops safety‑critical software that runs on Terran R, spanning a distributed, real‑time control system operating under extreme conditions. The team builds new system architecture from the ground up and focuses on testing, releasing, and deploying it.

• Design, develop, and maintain mission‑critical, Linux‑based infrastructure supporting command, telemetry, simulation, and automated test systems.
• Build and extend tools for executing tests across a range of environments, including virtual machines, HIL/SIL configurations, and vehicle‑in‑the‑loop setups.
• Optimize system performance and reliability, focusing on real‑time, high‑throughput data processing in Linux environments.
• Contribute to architectural decisions, sprint planning, and roadmap discussions to ensure scalable, maintainable systems.
• Collaborate with cross‑functional teams, including avionics, ground software, and flight software to ensure smooth integration and operational readiness.
• Mentor peers, share best practices, and help foster a culture of engineering excellence across the team.

• 5+ years of professional software engineering experience, including systems or infrastructure‑level development.
• Proficiency in Rust and/or Python, with strong understanding of performance, concurrency, and systems‑level programming.
• Experience developing in Linux environments, including working with real‑time or performance‑critical systems.
• Strong foundation in networking concepts (e.g., TCP/UDP, sockets, packet routing, protocol design).
• Experience building or maintaining reliable, testable software in CI/CD pipelines.
• Ability to design and deliver robust solutions for low‑latency, high‑throughput data pipelines.

• Experience with SIL, HIL, or real‑time simulation systems.
• Familiarity with real‑time Linux kernel tuning, system observability, or performance debugging.
• Experience building tools for command and telemetry injection, test automation, or avionics/hardware development environments.
• Exposure to robotics, aerospace, embedded systems, or other mission‑critical domains.
• Ability to lead technical investigations and contribute to architectural decisions in cross‑functional teams.
• Background working on distributed systems, large‑scale simulation environments, or hybrid software/hardware testing systems.
• Strong collaboration and communication skills, especially working closely with hardware, embedded, and flight software teams.
