About the role

The instrument operates in two modes: a sounder mode that measures subsurface layer reflections and a radiometer mode that measures the temperature of subsurface layers over a wide footprint.
Define the instrument calibration scheme for both radar and radiometer modes
Coordinate hardware development across RF, digital, power, and mechanical disciplines, along with firmware and software development

Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity.
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.
You will co-design the instrument against science objectives and develop the flight hardware and processing implementations.
Perform spectrum licensing and frequency coordination for instrument operation and testing and support instrument calibration and on-orbit commissioning
Design of mixed-signal and digital PCBs, such as software-defined radios or board-level FPGA designs

7+ years of experience in electrical hardware development, such as software defined radios, radar transceivers, or sophisticated digital processors
Experience with analysis and modeling of radar returns and radar performance
Experience implementing radio or radar transceivers as software-defined radios
Field testing, flight testing, or spaceflight experience with radio or radar transceivers
Experience with microwave radiometry or radiometer instrument design
Hands-on experience with AMD/Xilinx RFSoC or Zynq UltraScale+ platforms
Experience with spectrum licensing and frequency coordination for experimental or space systems
Experience with polarimetric radar and full-polarimetry calibration

The Interplanetary Sciences 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.
At Relativity Space, we are committed to transparency and fairness in our compensation practices.
At Relativity Space, we're building rockets to serve today's needs and tomorrow's breakthroughs.
Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level.
