The role

As a Staff Avionics Hardware Engineer within the Interplanetary Program at Relativity Space, you will take ownership of the design, development, and delivery of spacecraft avionics systems from concept through flight. You will collaborate with multidisciplinary teams to create reliable, high-performance avionics that enable deep-space exploration.

This position requires a highly motivated engineer who thrives in a fast-paced environment and can execute with autonomy. You will help define the foundation of Relativity’s future interplanetary avionics architecture while setting the technical standards for future team growth. Essential Duties and Responsibilities:

Develop complete avionics systems, including architecture, design, integration, and verification, from initial concept through flight-qualified hardware

Collaborate with propulsion, guidance and control, thermal and software teams to ensure seamless integration and performance of avionics systems

Implement robust design and test processes that ensure reliability and safety for deep-space missions

Lead the technical execution of avionics hardware builds, including PCB design, harnessing, embedded systems, and environmental qualification

Coordinate with suppliers and internal stakeholders to manage component selection, testing, and delivery schedules

Maintain accurate design documentation, test plans, and reports, demonstrating strong communication and organizational skills

The team

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.

What you need

Bachelor's or Master's degree in Aerospace Engineering, Electrical Engineering, or a related technical field
7+ years of experience designing, developing, and delivering avionics or electronics for aerospace systems or similarly complex environments
Demonstrated ability to take a design from concept through production with minimal supervision
Hands-on experience with schematic capture, PCB layout, embedded software interfaces, and system-level testing
Proven track record of working cross-functionally and communicating technical information clearly to diverse audiences
Ability to work effectively in a collaborative, fast-paced team environment, demonstrating adaptability and problem-solving skills

Nice to have

Direct technical experience in Mars missions is a plus
Experience with NASA aerospace systems engineering practices in an applied / new-space manner is a plus
Experience with deep-space or high-radiation avionics systems
Background in spaceflight hardware environmental testing and qualification
