Senior FPGA Engineer

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known. Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. About the Team The Avionics team is responsible for the full lifecycle of Terran R’s nervous system, designing, building, testing, installing, and operating the hardware that connects and controls every major electrical system on the vehicle and ground. The team leverages close partnership between avionics design, manufacturing, and test to enable rapid iteration and feedback loops. Engineers are deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation. Now is a unique time to join: you’ll get to help shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly. About the Role As an FPGA engineer on the digital electronics team, you will analyze, design, and test custom FPGA firmware on the Terran R launch vehicle. You will oversee development for FPGAs across multiple products through the entire product lifecycle from concept to flight maturity, including initial design, board bring‑up, design verification, qualification, initial flight production, integration, and vehicle operations. You will work with cross‑functional partner teams across the company to help the team make the best possible decisions for the overall vehicle. A strong candidate for the role will have a deep technical background in electronics design and sound project management skills to ensure the hardware project is both reliable and on‑schedule to support Terran R's launch. About You Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field 5+ years of experience in FPGA development and high‑speed digital systems in mission‑critical applications such as launch vehicles, spacecraft, aircraft, or robotics Technical expertise in FPGA development across the full lifecycle: RTL design, verification, synthesis, timing analysis, and bring‑up/validation Familiarity with one or more Hardware Description Languages (HDLs) including VHDL, Verilog, or SystemVerilog Experience with hardware bring‑up, validation, debugging, and data analysis Experience working with highly cross‑functional teams (mechanical, thermal, electrical, software, etc.) to develop integrated electronics solutions Familiarity with a wide variety of FPGA toolchains and SoC platforms across industry leaders like AMD Xilinx, Intel, Microchip, etc. Nice to haves but not required Strong experience in DSP concepts in RF applications such as forward error correction, channel estimation, front end theory, and modulation schemes Familiarity with one or more code generation or High Level Synthesis (HLS) languages including SpinalHDL, Chisel, Vitis, SystemC, or Simulink Familiarity with RISC‑V development toolchain (e.g., linker scripts, compilers) Familiarity with rigorous software development processes including version and configuration control, change traceability, code coverage analysis, CI/CD build pipelines, etc. Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more. Hiring Range
