Wiring Harness Engineer Verified today

About the Role

Design and integrate robust electrical harnessing systems for our spacecraft platforms. You will own the end-to-end cable harness architecture, design, routing, and manufacturing processes across flight and ground systems. Work closely with avionics, mechanical, and optical teams to route power, high-speed data, and optical signals reliably through tight spacecraft volumes, surviving harsh launch vibrations and thermal vacuum conditions in space.

Responsibilities

• Own the technical roadmap and architecture for electrical and optical harnessing across all spacecraft platforms.
• Create detailed harness schematics, routing diagrams, 3D CAD models, and manufacturing drawings.
• Design robust cable harness assemblies which meet strict mass, volume, and thermal constraints.
• Select space-rated connectors, wire types, shielding materials, and other harness components.
• Define comprehensive electrical harness testing protocols and lead their execution to validate flight readiness and system reliability.
• Lead prototype assembly, environmental testing (vibration, thermal vacuum), and qualification of harness hardware.
• Collaborate with mechanical and optical teams to ensure proper clearance, strain relief, and mechanical interface compatibility.
• Support integration and test campaigns on the manufacturing floor and during final spacecraft assembly.

Basic Qualifications

• Bachelor's degree in Mechanical Engineering, Electrical Engineering, Aerospace Engineering, or a related technical discipline.
• 2+ years of experience designing and routing complex wire harness assemblies for aerospace, defense, or high-reliability hardware.
• Proficiency with 3D CAD software (e.g., NX, CATIA, SolidWorks) and dedicated harness routing modules.
• Experience creating detailed manufacturing drawings, flat patterns, and engineering bills of materials (BOM).
• Hands-on experience building, prototyping, and troubleshooting wire harnesses or mechanical assemblies.

Preferred Qualifications

• 5+ years of experience designing and routing complex wire harness assemblies for aerospace, defense, or high-reliability hardware.
• Familiarity with Altium Designer for interpreting electrical schematics and defining harness pin-outs.
• Deep knowledge of space-industry harness standards, including NASA-STD-8739.4 or IPC-WHMA-A-620 space addendum.
• Familiarity with EMI/EMC shielding techniques and grounding methodologies for aerospace systems.
• Experience managing spacecraft hardware through environmental test cycles, including vibration, shock, and thermal vacuum (TVAC) testing.
• Experience designing fiber-optic harnesses, handling optical fibers, and selecting space-rated optical connectors.
• Proven ability to work in a fast-paced, high-growth startup environment with cross-functional technical teams.

Compensation

Salary range: $100,000 to $135,000 annually, depending on job-related skills, experience, qualifications, and internal equity.

Benefits include equity in Cowboy Space Corp., medical/dental/vision insurance, 401(k) retirement plan, paid time off, 10 paid holidays per year, paid parental leave, relocation assistance if applicable, daily office lunch, and fully stocked kitchen.

ITAR Requirements

To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR), applicants must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain required authorizations from the U.S. Department of State.
