Avionics Harness Mechanical Design & Analysis Engineer II Verified today
About the role
This position is part of Blue National Security, focused on launch and spacecraft systems for national security missions. You will design, analyze, integrate, and test avionics routed interconnect systems for the Blue Ring hybrid solar-electric and chemical-propelled spacecraft.
You will own the mechanical design and analysis of electrical harness routing, installation hardware, and support brackets. You'll work in a cross-disciplinary team with electrical, mechanical, structural, manufacturing, and systems engineers to develop reliable electrical harness installations for harsh space environments.
Your 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 per ASME Y14.5 to harness hardware, brackets, and installation interfaces
- 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
Minimum 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 per 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
Preferred qualifications
- Experience with Creo Schematics, Zuken, Windchill, or similar CAD and PLM tools
- Experience with ANSYS or comparable structural FEA software
- Experience developing free-body diagrams and hand calculations for launch, random vibration, shock, fatigue, and fastener loading
- Experience routing and installing RF coaxial cable, high-speed data cables, fiber optics, or other specialty interconnects
- Experience designing lightweight sheet-metal, machined, or additively manufactured harness brackets
- Experience supporting environmental testing, including vibration, shock, thermal vacuum, and qualification or acceptance testing
