Job summary

Blue Origin is seeking an electrical harness designer to own the mechanical design and analysis of harness routing, installation hardware, and support brackets for spacecraft. You will develop 3D routed harness models, 2D drawings, and interconnect diagrams while applying GD&T and structural FEA.

Responsibilities include design optimization, BOM management, and collaboration with manufacturing to ensure producibility and test readiness for national security missions.

Qualifications

• B.S. degree in Mechanical, Aerospace, Electrical, Electromechanical Engineering, or a related technical field.
• 2+ years of experience designing and integrating wire harnesses for spacecraft, launch vehicles, aircraft, or similar high‑performance systems.
• Experience with 3D CAD‑based electrical and mechanical routing; Creo and Creo Routed Systems are preferred.
• Experience creating harness schematics, system interconnect diagrams, block interconnect diagrams, or wiring interconnect diagrams.
• Experience designing harness installation hardware and support brackets.
• Working knowledge of GD&T implementation and tolerance analysis in accordance with ASME Y14.5.
• Experience performing structural FEA and engineering hand calculations for brackets, supports, fasteners, or similar mechanical hardware.
• Knowledge of aerospace structural design criteria, margins of safety, material allowables, and fastener analysis.
• Ability to interpret mechanical and electrical interface requirements and integrate harnesses within complex vehicle assemblies.
• Familiarity with applicable harness workmanship and design standards, including IPC/WHMA‑A‑620 and NASA‑STD‑8739.4.
• Strong mechanical design, analytical, problem‑solving, and technical communication skills.
• Ability to be self‑directed, manage multiple priorities, and work effectively across engineering disciplines.

Responsibilities

• Develop and analyze electrical harness designs as part of a cross‑disciplinary engineering team.
• Create and maintain system interconnect diagrams, block interconnect diagrams, wiring interconnect diagrams, and schematics.
• Design and integrate 3D electrical harness routing on spacecraft vehicle assemblies.
• Develop 2D flattened harness drawings, harness installation drawings, detail drawings, and assembly drawings.
• Design harness support hardware, including brackets, clips, clamps, standoffs, shields, and related mounting provisions.
• Apply geometric dimensioning and tolerancing in accordance with ASME Y14.5 to harness hardware, brackets, installation interfaces and drawings.
• Perform structural FEA and engineering hand calculations for harness brackets and support hardware, including static strength, stiffness, fastener loads, vibration response, and margins of safety.
• Conduct design and analysis trade studies to optimize harness routing, support spacing, installation accessibility, mass, manufacturability, and structural performance.
• Select and integrate harness components, including connectors, backshells, wire, cable, RF coax, shielding, sleeving, clamps, and attachment hardware.
• Support electrical and mechanical configuration management, including engineering bills of material and product lifecycle management.
• Evaluate harness designs for bonding, grounding, shielding, separation, bend radius, thermal considerations, and protection from abrasion or mechanical damage.
• Define and verify design requirements through analysis, inspection, test, and similarity.
• Support test planning, test execution, data review, nonconformance resolution, and hardware troubleshooting.
• Collaborate with manufacturing and integration teams to ensure designs are producible, inspectable, and installable.
• Communicate design and analysis results through technical reports, design reviews, and certification documentation.
