Spacecraft Harness Design Engineer III - TeraWave

Applications will be accepted on an ongoing basis until the requisition is closed.

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.

As a Harness Design Engineer III, you will help lead Bundle Interconnect Diagrams (BIDs) and Wire Interconnect Diagrams (WIDs) development for assigned subsystem areas, serve as a technical point of contact for subsystem interface coordination, and mentor junior team members. This is expected to operate with a high degree of autonomy.

• Independently lead BID/WID development for assigned subsystem areas (e.g., EPS/power distribution, GNC/navigation, and/or payload interfaces)
• Produce and conduct peer reviews of harness drawings
• Serve as technical point of contact for assigned subsystem interfaces – coordinate directly with LRU/box owners
• Lead harness analysis packages (voltage drop, derating, mass estimation) for assigned areas
• Support the Harness Design Lead in defining harness architecture and design standards
• Mentor Level I and Level II engineers on harness design best practices and Blue Origin command media

• Create detailed harness assembly drawings, installation drawings, and connector pin assignment documentation
• Perform harness analysis including voltage drop calculations, current derating analysis, and mass estimation
• Conduct 3D harness routing and clearance verification using spacecraft CAD models
• Define harness segregation requirements for power, signal, and RF interfaces to ensure EMI/EMC compliance
• Specify connector types, wire gauges, shielding requirements, and termination methods for all harness branches
• Support harness design reviews and coordinate resolution of design issues with cross‑functional teams

• Collaborate with manufacturing engineering to ensure harness designs are optimized for production
• Support harness fabrication shops during build activities including first article reviews and nonconformance disposition
• Participate in spacecraft integration and test activities to verify harness installation and functionality
• Develop harness installation procedures and work instructions for integration teams
• Support troubleshooting of harness‑related issues during spacecraft assembly and test

• Bachelor's degree in Electrical Engineering, Aerospace Engineering, Mechanical Engineering, or related technical field
• 7+ years of experience in spacecraft or satellite harness design, cable routing, or electrical integration
• Extensive experience producing harness assembly drawings, installation drawings, and connector pin assignment documentation
• Strong 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)
• Solid knowledge of harness fabrication standards
• Strong understanding of EMI/EMC principles as applied to harness segregation, shielding, and grounding
• Expert 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
• Demonstrated ability to lead technical discussions and coordinate with cross‑functional teams

• Experience with Creo Cabling / Routed Systems and Windchill PLM for harness configuration…
