Senior RF Engineer

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Interplanetary Program was established to expand access to scientific exploration across our solar system. Its mission is to make planetary research faster more affordable and more capable than ever before by rethinking how science missions are designed built and operated. The program aims to enable scientists to send instruments to distant worlds without decades of development or prohibitive costs. By creating a sustainable model for interplanetary exploration we are transforming space science from an occasional event into a continuous process of discovery that accelerates knowledge broadens participation and inspires the next generation of explorers.

About the Role:

As an RF Engineer on Relativitys Interplanetary Program you will own the architecture design development testing and operation of next-generation high-reliability RF systems that enable deep-space communication navigation and science operations. You will work hands-on across the full lifecycle from concept and link budgets to working with ground stations (i.e. DSN KSAT etc.) through hardware bring-up environmental qualification integrated testing and flight readiness. This role partners tightly with avionics optical comms and spacecraft REs to ensure our RF subsystem integrates cleanly into the overall spacecraft bus. You will be responsible for solving engineering challenges that push the boundaries of RF technologies: designing for extreme distances measuring in AUs low-SNR environments radiation effects and highly constrained mass/power budgets. This is a highly technical hardware-first role in a scrappy hands-on environment and team where iteration speed analytical rigor and end-to-end ownership of the problem space will be critical to the success of the mission.

About You:

• Bachelors degree in Electrical Engineering Computer Engineering Physics or a related field
• 5 years of experience in RF communication system architecture analysis and/or component engineering
• Experience with 3 or more of the following:
  • RF architecture & link budgets for challenging environments
  • Selection design and/or integration of RF systems including transmitters receivers LNAs PAs frequency sources converters and front-end architecture.
  • Selection and/or design of RF passive components such as filters diplexers couplers and waveguide components
  • Antenna design analysis and modeling tools
  • Hands-on testing with RF lab equipment such as spectrum analyzers VNAs SDRs power meters and data recorders
  • Hands-on integrated testing with ground stations and/or integrated spacecraft RF systems to flow live telemetry and commanding
• Experience communicating deeply technical topics with individuals from different disciplines

Nice to haves but not required:

• Experience with space environments (radiation effects thermal extremes vacuum operation component derating)
• Prior work with deep-space spacecraft comms system design & architecture
• Prior work with deep-space ground station networks
• Experience with high-gain antennas phased arrays or gimbaled antenna systems
• Experience designing or validating RF hardware for flight qualification (TVAC vibe EMI/EMC)
