About The Position

As the Lead Engineer for the Avionics System within the Interplanetary Program, you will own revolutionizing the next generation of in-space compute and storage capability by leveraging the latest terrestrial technologies and challenging the status quo of how high-capability compute and storage are done in the space sector.
You will be responsible for delivering fully functional space-ready compute units to the flight spacecraft as well as setting up ground-based hardware twins for hardware in the loop and terrestrial based compute capability. You will be working closely with the science team to maximize capability by balancing the compute (CPU, GPU, TPU, etc..), memory, storage needs with the technical constraints of the flight spacecraft (power, thermal, EMI, mechanical, etc…). This role will also work closely in conjunction with the software team to bring up the core software infrastructure both on the spacecraft and on the ground side, and iterating with the software team to ensure the full compute system operates as intended in all environments.
This role will be a high responsibility, high autonomy, and high accountability role within a fast-paced, iterative environment, where rapid prototyping, early testing, and continuous learning are key to success. You’ll lead hands-on development campaigns to evaluate key technologies, derisk interfaces, and validate performance before full system integration. You’ll also work across internal and external teams to turn concepts into hardware, balancing agility and rigor as you move quickly from analysis to prototypes to flight-ready systems.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Physics, or a related technical field
• 7+ years designing and delivering digital, compute-centric electronic systems
• Proven experience leading design and delivery of complex electrical systems, including RF and compute-heavy projects
• Hands-on work with challenging thermal and electromechanical environments
• Strong grasp of systems engineering, interface management, and risk management principles for complex programs
• Excellent technical communication, problem-solving, and cross-disciplinary collaboration skills

Nice To Haves

• Direct architecture or EE design experience with non-volatile storage, mobile compute, and/or server class computing is a plus
• Experience with compute and storage survivability in space and radiation environments is a plus
