Job description

Senior Avionics Mechanical Design Engineer

Long Beach, California

At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs.

Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.

About the Team:

The Avionics team is responsible for all aspects of the electrical design on the rocket, from electronics, interconnects, associated mechanical design, testing and initial production. This team's scope includes the flight computers, power systems, RF systems, PCB design, autonomous flight safety systems, and telemetry. This team works on complex electrical systems that require modularity and flexibility, and are critical to the successful launch of Terran R, and beyond!

About the Role:

• Own the design, analysis, and test/validation of mechanical products within the Terran R avionics system. Mechanical products include electronics enclosures, vibration isolation, thermal management, and environmental protection devices.
• Collaborate with electrical engineers to design robust, high-performance printed circuit board assemblies.
• Perform preliminary sizing for static and dynamic loads and thermal environments.
• Utilize 3D modeling and 2D drafting packages to deliver detailed designs with considerations for production and test.
• Validate designs for flight through rapid prototyping, analysis, and test campaigns.

About You:

• Minimum of 5+ years of experience in a full cycle mechanical design engineering role.
• Bachelor’s degree in mechanical engineering, aerospace engineering, or related field.
• Experience with 3D computer-aided design (CAD) software.
• Experience with structural and thermal analysis.
• Demonstrated project ownership and accountability with complex, multi-disciplinary technical projects.

Nice to haves but not required:

• Experience with the design of electronic assemblies, batteries, and/or vibration isolation systems.
• Experience with finite element analysis methods.
• Applied knowledge of geometric dimensioning and tolerancing (GD&T).
• Proficient with NX/Teamcenter CAD package.

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.

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:

$159,000 - $204,000 USD
