Senior Avionics Mechanical Engineer

About 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.

About the Role:

As a Senior Avionics Mechanical Engineer you will own the design development and delivery of all mechanical hardware supporting our next-generation space science avionics platforms. This includes enclosures mounting structures thermal accommodations and interfaces to spacecraft systems. You will be responsible for ensuring the delivered Avionics can survive launch and space environments and for solving complex thermal and structural challenges in tight mass-efficient packaging.

This is a hands-on role for a self-driven engineer who thrives in a fast-paced prototype-heavy environment. You’ll work from first principles to rapidly iterate on designs perform analysis and testing and lead the delivery of flight-ready avionics mechanical systems.  

About You:

• Bachelor’s or Master’s degree in Mechanical Engineering Aerospace Engineering or a related field
• 5+ years of experience in mechanical design packaging or thermal management for aerospace or ruggedized electronic systems
• Proven ability to deliver mechanical systems from concept through qualification and flight
• Proficiency with CAD (SolidWorks NX or equivalent) and analysis tools for structural and thermal performance
• Hands-on experience building testing and debugging hardware in a lab environment
• Strong communication skills and comfort working cross-functionally in a fast-paced rapidly iterating team environment

Nice to haves but not required:  

• Familiarity with NASA or other spaceflight structural verification standards environmental testing and qualification
• Experience designing mechanical systems for spaceflight avionics or payloads
• Experience with high-density electronics cooling (conduction heat pipes cold plates)
• Knowledge of materials and processes for vacuum and radiation environments

What We Do

Relativity Space is on a mission to better connect humanity to space and the universe beyond our planet. Our medium-to-heavy lift reusable rocket Terran R will deliver customer payloads to orbit meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science exploration and innovation pioneering progress that reaches beyond the known.

Why Work With Us

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. 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.
