Principal Mechanical Engineer – Satellite Systems

We’re building the future of space access by designing and delivering high-performance satellite platforms that scale from demonstration missions to full constellations. Our integrated bus and payload approach offers customers a faster, more reliable path from concept to orbit. If you’re passionate about precision engineering and want your work to fly, we’d love to meet you.

As a Principal Mechanical Engineer, you’ll lead the mechanical design and development of our satellite platforms—from structural architecture to thermal management and system integration. You’ll work cross-functionally with avionics, propulsion, RF, and systems teams to deliver flight-ready hardware that meets aggressive performance, mass, and schedule goals.

• Own the end-to-end mechanical design of satellite structures, enclosures, and thermal systems
• Lead design trades, modeling, and analysis (FEA, thermal, vibrational, etc.)
• Drive CAD development, drawings, and GD&T to production quality
• Oversee manufacturing processes, DFM/DFA reviews, and vendor interactions
• Develop and execute environmental test plans (TVAC, vibration, shock)
• Mentor junior engineers and shape mechanical engineering best practices
• Contribute to system-level architecture and integration strategies

• B.S. or M.S. in Mechanical Engineering or related field
• 7+ years of experience designing and building complex mechanical systems; aerospace strongly preferred
• Proven flight heritage on spacecraft, aircraft, or similar high-reliability systems
• Proficiency in CAD (e.g., SolidWorks, Creo) and FEA tools (e.g., ANSYS, NASTRAN)
• Deep understanding of structural dynamics, thermal design, and materials for space environments
• Strong communication and leadership skills in a fast-paced, iterative environment

Nice to Have:

• Experience with rapid hardware iteration or satellite production lines
• Knowledge of deployables, mechanisms, and propulsion integration
• Familiarity with spaceflight qualification standards (NASA GEVS, MIL-STD-1540)

• Be part of a tight-knit team building actual spacecraft that launch and operate
• Influence the design of a scalable satellite platform from the ground up
• Competitive salary, meaningful equity, and full benefits
