Mechanical Design Engineer

Location: Los Angeles, CA — On-site, 5 days/week

Salary: $95,000 – $180,000 + equity + annual performance bonus

Type: Full-time


A well-funded, mission-driven space technology company is moving fast and building real flight hardware. They’re hiring a Mechanical Design Engineer to own the design, analysis, and development of hardware. This is a true hands-on role at the intersection of structures, thermals, mechanisms, and aero, working shoulder-to-shoulder with GNC, TPS, test, avionics, manufacturing, and integration teams.


What you’ll do:


  • Design mechanical systems for atmospheric recovery: deployables, aerodynamic decelerators, recovery mechanisms, interfaces, and precision landing hardware
  • Own hardware end-to-end: concept → requirements → CAD → FEA → prototype → assemble → qualify → flight
  • Perform structural/thermal/mechanism analysis for extreme loads, temperatures, and dynamics
  • Lead integration across rigid structures + soft goods (e.g., paraglider/parachute-style systems) and flight hardware
  • Support and drive test campaigns (ground, wind-tunnel, and flight) and iterate quickly
  • Run design reviews (PDR/CDR) and produce clear drawings, BOMs, documentation, and work instructions


What they’re looking for:


  • 3–5 years of industry experience designing aerospace mechanical hardware
  • Strong CAD skills (SolidWorks, NX, or similar) and analysis ability (structural/thermal in ANSYS preferred; SolidWorks acceptable)
  • Experience with structures, mechanisms, deployables, and aero-structures (e.g., flaps, hinges, linkages, and ideally parachute/paraglider-adjacent components)
  • Strong understanding of load paths, interfaces, and environmental requirements for high-energy flight environments
  • Proven ability to take hardware from concept to production and/or flight
  • Comfortable with ambiguity, rapid iteration, and fast design–build–test cycles
  • Excellent documentation and communication skills


Nice to have:


  • Reentry systems, atmospheric flight vehicles, TPS interfaces
  • Soft goods integration with rigid structures
  • Hypersonic/supersonic/high aero-load environments
  • Field test experience (drop tests, flight tests, deployment tests)
  • Precision actuation / DOF-limited mechanisms in harsh environments


Benefits snapshot:


  • Equity + bonus
  • Medical, dental, vision
  • Short/long-term disability + life insurance
  • PTO + 401(k) with company match
  • Subsidized catered lunch/snacks/coffee
