Principal Mechanical Engineer Satellite Systems

Who We Are 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. Who You Are As a Principal Mechanical Engineer, you'll lead the mechanical design and development of our satellite platformsfrom 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. What You'll Do 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 What You Bring 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) What We Offer 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
