Electromechanical Engineer (All-Levels)

Department: Avionics

Employment Type: Full Time

Location: Hawthorne, CA, Hawthorne, California, Hybrid

What you'll do:

• Lead the mechanical and structural design of space-qualified electronics enclosures, ensuring survival under launch random vibration, acoustic loads, and shock environments
• Select flight-proven materials, surface treatments, and staking compounds while balancing structural stiffness, thermal conductivity, electrical bonding, and outgassing limits
• Produce flight drawing packages with precise GD&T, fastener torque schedules, and electrical grounding and bonding callouts per spaceflight standards
• Collaborate closely with thermal analysis teams to verify conductive thermal paths from high-power die and board interfaces to chassis conduction decks and radiator interfaces in vacuum
• Integrate passive and active thermal control hardware, including heat pipes, thermal straps, thermal interface materials, operational and survival heater circuits, RTDs, thermistors, and multi-layer insulation (MLI) blankets
• Architect static and articulated or dynamic harness installations, including cable wrap mechanisms, service loops, twist capsules, and flex or rigid-flex jumper assemblies
• Design custom brackets, harness support trays, strain relief features, and breakout bulkheads optimized for mass, mass-elastic constraints, and design for manufacturability (DFM)
• Present and defend mechanical packaging, harness routing schemes, and thermal hardware implementations at formal milestone reviews, including PDR, CDR, TRR, and MRR 

What you'll bring:

• Bachelor’s degree in a science, technology, engineering or mathematics (STEM) related field
• 1+ years of experience designing and developing physical hardware for high-reliability applications
• Experience using 3D CAD software such as Siemens NX, Creo, or SolidWorks, including mechanical packaging, sheet metal, and machined enclosures
• Experience working with electrical harnesses, interconnects, wire routing, shielding, and grounding for complex hardware systems

• Experience applying thermal management concepts, including heat sinks, thermal interface materials, heaters, and thermal paths for hardware operating in controlled or vacuum environments
• Master’s degree in a science, technology, engineering or mathematics (STEM) related field
• Experience designing or supporting flight-qualified hardware for satellites, launch vehicles, lunar landers, space robotics, or other aerospace systems
• Experience using 3D harness routing or electrical routing tools, such as Capital Harness, Zuken E3, or NX Electrical Routing
• Experience developing rigid-flex PCB physical layouts or continuous-flex interconnects for moving mechanisms, gimbals, or deployment systems
• Experience working with spaceflight interconnect standards and requirements, including IPC/WHMA-A-620 Space Addendum and NASA-STD-8739.4
• Experience designing or implementing MLI for vacuum environments
• Experience performing bonding and grounding verification, including low-resistance or milli-ohm measurements
• Experience designing or supporting vehicle harness bundles or avionics enclosures used in operational aerospace systems
