Spacecraft Harness Engineer - Millennium Space Systems

Job Description

At Millennium Space Systems, a Boeing Company, we deliver affordable, high‑performance space systems for exacting customers. We work in an open environment where ideas are shared across all disciplines, and there are ample opportunities for advancement based on excellence.

As a Lead Spacecraft Harness Design Engineer, you will work with a small team on exciting and fast‑paced space missions. In this role, you will provide electrical wiring interconnect systems (EWIS) for our advanced research, development, and prototype division. You will support iterative R&D environments and transition missions into high‑rate production, managing complex interfaces and innovating as needed.

• Development & analysis of EWIS architectures for multiple programs and bus configurations, ranging from experimental LEO small sats to MEO constellations and GEO vehicles.
• Generation of subsystem or unit‑to‑unit electrical block diagrams.
• Definition and documentation of signal connectivity through cross‑functional coordination for spacecraft harness or printed wiring board design.
• Selection of harness components and hardware, including connectors, backshells, and wire/cable based on applicable satellite mission requirements and industry standards.
• Performance of voltage drop analysis, power current derating, and capacitance circuit analysis for harness and printed wiring boards.
• Development and analysis of PCB designs, determination of board form factor, schematic capture, board stack, component placement and trace routing.
• Generation of rigid or rigid‑flex PCB, PCB Assembly Drawings, fabrication & assembly output files (Geber, ODB++, etc.).
• Generation harness schematic diagrams, wire diagrams, and wire harness assembly drawings.
• Preparation and generation of harness acceptance testing procedures, including test scripts for cable testers.
• Participation in critical programmatic milestones (PDR, CR, etc.), preparing data packages, conducting design reviews, and closing any liens from the Milestone Decision Authority (MDA).
• Support assembly and testing of Flat Sat and flight harnesses while reporting on cost and schedule performance.
• Capture of as‑built, mock‑up harness builds to produce 2D/3D form boards.
• Support creation, maintenance, or update of harness design, assembly, and test standards and command media.
• Support proposals and business development efforts as the responsible engineering authority (REA).
• Management of external suppliers and subcontractors for harness and printed circuit board delivery.

• Bachelor’s or higher degree in Electrical Engineering or related technical discipline.
• Level 2:
  Minimum 2 years of relevant engineering experience with a bachelor’s degree, or possession of a higher degree with no work experience.
• Level 3:
  Minimum 5 years of relevant engineering experience with a bachelor’s degree, or 3 years with a higher degree.
• Ability to create detail‑oriented designs while maintaining higher‑level design requirements.
• Excellent communication skills and ability to work effectively with others.
• Ability to work independently with limited technical oversight.
• Ability to create and revise technical documents for programmatic or strategic tasks.
• U.S. citizenship required; ability to obtain and maintain a U.S. security clearance.

• Active DoD TS/SCI clearance.
• Experience with the design and delivery of spacecraft or aircraft wire harnesses and/or printed circuit boards; rigid‑flex PCB design preferred.
• Experience with early life‑cycle satellite engineering, spacecraft integration and test, and launch operations.
• Experience with Earned Value Management Systems (EVMS).
• Proficiency using harness design software (Mentor Graphics, E3 Zuken, or CATIA) and Microsoft Access and Visio.
• Proficiency using PCB design software (Nexus Zuken or Siemens Xpedition).
• Knowledge of harness design standards for spaceflight (MIL‑HDBK‑83575, MIL‑HDBK‑863, SAE AS50881, etc.).
• Knowledge of PCB design standards (IPC‑2221, 2222, 2223, IPC‑A‑600, etc.).
• Knowledge of military connector, wire, and contact standards for aerospace (MIL‑DTL‑38999,…
