Spacecraft Mechanical Engineer - Own Hardware & Build

EVONA; Los Angeles (CA); On-site; USD 120,000 - 170,000; Full time

Job summary

EVONA is seeking a Mechanical Engineer to design, analyze, build, and test critical spacecraft and propulsion hardware in Los Angeles. This hands-on role involves moving between first-principles analysis and detailed mechanical design, manufacturing, integration, testing, and post-test evaluation.

You will own major spacecraft hardware and collaborate with propulsion, avionics, controls, and vehicle systems engineers in a small, ownership-driven team.

Qualifications

• B.S. in Mechanical Engineering, Aerospace Engineering or related technical discipline.
• 2+ years designing, analyzing, building, or testing aerospace hardware or similar complex systems.
• Strong CAD fundamentals with drawings, tolerancing (GD&T) and manufacturing considerations.
• Hands-on experience with flight hardware, prototype hardware, or complex test equipment.

Responsibilities

• Own mechanical design, component selection, and integration for spacecraft, propulsion systems, mechanisms, robotics, and ground-test equipment.
• Design and integrate mechatronic systems supporting key vehicle functions.
• Develop calculations, simulations, and engineering models to drive design decisions.
• Produce CAD models, engineering drawings, interface definitions, assembly procedures, and test documentation.
• Perform mechanical and structural analysis using hand calculations, FEA, Python, MATLAB, and other engineering tools.
• Work closely with manufacturing teams to take designs from concept into physical hardware.
• Plan, execute, and troubleshoot structural and mechanical testing.
• Review test data and use results to rapidly iterate hardware designs.
• Take ownership of hardware throughout the full development lifecycle.
