Senior Harness Engineer

Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions.

The company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach.

Headquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry.

As a Senior Harnessing Engineer at Inversion, you will report directly to the Director of Engineering, Avionics. In this role, you will own the end-to-end design, 3D routing, documentation, and physical integration of all electrical wire harnesses for Inversion’s hypersonic reentry vehicle. You will bridge the gap between electrical schematics and physical vehicle structures, solving complex packaging, thermal protection, and electromagnetic interference (EMI) challenges. Operating with high autonomy, you will establish harness manufacturing standards, mentor junior engineers, and work directly with integration technicians to build and route flight-ready hardware.

• →Own the 3D harness routing and mechanical packaging of the entire vehicle electrical distribution system using CAD.
• →Generate 2D harness manufacturing drawings, schematics, flat patterns, nail board layouts, and bill of materials (BOM).
• →Select wire types, shielding, connectors, back shells, and over-braid materials to survive extreme aerospace environments (high vibration, vacuum, thermal, and plasma).
• →Conduct trade studies on shielding, grounding, and wire sizing to ensure proper power delivery, signal integrity, and EMI/EMC compliance.
• →Author detailed harness fabrication procedures, routing checklists, and electrical inspection plans (continuity, isolation, and dielectric testing).
• →Provide hands-on floor support during harness manufacturing, vehicle-level routing, and pin-out operations.
• →Mentor junior engineers and support technician training on aerospace-grade wire-crimping, shielding termination, and soldering techniques.

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, or equivalent technical experience.
• Typically 5+ years of hands-on experience in 3D CAD electrical harness routing and design for complex aerospace vehicles.
• Proficiency in CAD software (Siemens NX or equivalent) with specialized routing modules.
• Deep understanding of wire harness design principles, including component selection, wire sizing, shielding, grounding, and routing clearances.
• Direct experience generating production-ready 2D harness drawings with detailed standard dimensions and notes.
• Hands-on harness build experience.
• Excellent verbal and written communication skills.
• Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.

• Familiarity with aerospace harnessing and soldering standards.
• Experience designing harnesses for extreme thermal gradients, vacuum outgassing, and high-vibration rocket or reentry environments.
• Familiarity with harness electrical analysis tools, schematic capture tools, and database management systems.
• Prior experience in a fast-paced aerospace startup or small hardware integration team.
