Spacecraft Harness Design Engineer III - TeraWave

Spacecraft Harness Design Engineer

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

Blue Origin is pioneering the future of space-based communications with Tera Wave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.

Responsibilities include but are not limited to:

• Design, develop, and release spacecraft wire harness assemblies for bus, payload, and integration applications across the Tera Wave satellite constellation
• Develop Bundle Interconnect Diagrams (BIDs) and Wire Interconnect Diagrams (WIDs) in coordination with LRU/box owners across all subsystems (avionics, propulsion, GNC, RF payload, optical payload, solar array, thermal)
• Produce harness engineering drawings including harness assembly drawings, installation drawings, and connector pin assignment drawings
• Create and maintain 3D harness routing models in Creo/Windchill, performing interference checks, bend radius verification, and mass/length estimation
• Work to harness specifications, workmanship standards, and design requirements aligned with Blue Origin command media
• Select connectors, backshells, contacts, and interconnect hardware appropriate for the space environment (vacuum, thermal cycling, radiation, vibration)
• Define connector keying, clocking, and pin assignments to ensure proper mating and prevent misconnection during integration
• Specify shielding termination methods (360° backshell termination, pigtail, drain wire) based on EMI/EMC requirements and signal type
• Perform harness-related analyses including voltage drop, wire derating, current capacity, weight estimation, and thermal dissipation
• Support EMI/EMC analysis for harness segregation planning — separate power, signal, and RF runs per the Electromagnetic Effects Control Plan
• Coordinate with manufacturing engineering on harness fabrication — support make/buy decisions, develop build instructions, and resolve production issues
• Support harness fabrication to specified workmanship standards
• Develop test procedures for harness acceptance testing (continuity, hipot, insulation resistance, megohm)
• Support vehicle integration and test — troubleshoot harness anomalies, process redlines, and support connector mate/demate operations
• Design harnesses for manufacturability and rate production — minimize harness variants, standardize connector families, and optimize for assembly time at constellation scale (5,408 satellites)

• Bachelor's degree in Electrical Engineering, Aerospace Engineering, Mechanical Engineering, or related technical field
• 5+ years of experience in spacecraft or satellite harness design, cable routing, or electrical integration
• Demonstrated experience producing harness assembly drawings, installation drawings, and connector pin assignment documentation
• Hands-on experience with BID/WID development and interface coordination across multiple subsystems
• Proficiency with electrical harness CAD tools (Creo Cabling / Routed Systems, Zuken, Capital Harness, Mentor/Siemens, or equivalent)
• Working knowledge of harness fabrication standards
• Understanding of EMI/EMC principles as applied to harness segregation, shielding, and grounding
• Familiarity with connector systems used in space applications (Micro-D, Nano-D, D-sub, circular MIL-DTL-38999, MIL-DTL-83513, etc.)
• Ability to read and interpret electrical schematics, Block diagrams, and interface control documents
• Strong attention to detail and ability to manage multiple concurrent harness designs in a fast-paced environment
• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a…
