Salary: USD 104,000 - 143,000 / annual
Relativity Space is building rockets to serve today's needs and tomorrow's breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting growing demand for launch capacity. The company is developing a rocket, factory, and business from the ground up, with a culture emphasizing autonomy, ownership, and impact at every level.
The Launch team operates at the intersection of every major aspect of Terran R, from stages and payloads to ground systems, launch, landing, and refurbishment. Based at the Cape, this team sees first flights, historical milestones, and operates at a scale unlike anything in modern aerospace. The work evolves with every milestone: from first launch to reuse, high-cadence operations, and beyond.
As a Mechanical Engineer II on the Launch team, you will lead mechanical design projects from concept through implementation using sound engineering principles. You will coordinate technical requirements with vehicle and ground support engineering teams, develop detailed 3D CAD models, 2D mechanical drawings, fluid system schematics, and electrical system schematics. You will perform structural, dynamic, and system performance analyses using hand calculations and finite element methods (FEM). You will present design concepts and project updates to engineering and cross-functional teams, emphasizing functionality, feasibility, and safety.
This role offers exposure and responsibility unmatched elsewhere in the program. You'll define what's next in space launch and write a new playbook, not just repeat what's already been done.
REQUIREMENTS:
- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or closely related field
- Minimum 2 years of professional engineering experience in structural systems, mechanical design, fluid power systems, or related areas
- Solid understanding of mechanical engineering principles, including structural analysis and fluid systems design
- Proven ability to deliver high-quality results on schedule, including under challenging or ambiguous conditions
NICE TO HAVES:
- Experience with launch vehicle interface mechanisms, support tooling, or similar systems
- Familiarity with applicable NASA, DoD, Space Force, or related industry standards
- Working knowledge of structural materials, manufacturing methods, and fabrication processes
- Experience designing complex fluid systems (e.g., high-pressure gas, cryogenic, flammable fluids, or hydraulics)
