Company:

Millennium Space Systems

Millennium Space Systems (MSS), a part of Boeing Defense, Space and Security (BDS), is a fast, agile small satellite company focused on national security space. Our missions have direct impact to global security, like missile warning and Earth observation.

Our team is curious, bold and innovative. We take risks, innovate and explore new techniques and technologies. We influence change because we challenge the status quo. And when we watch our satellites launch, we know each one of us made it happen.

Millennium Space Systems (MSS) has an exciting opportunity for a Spacecraft Harness Engineer (Level 2 or Level 3) to join the MSS team in El Segundo, CA!

You will be working in missions with continuous changing requirements and expectations, typical of research & development (R&D) environments, and support transitioning missions into high-rate production.

We are looking for talented individuals who can manage complex interfaces and are willing to innovate. Talented individuals with strong foundations in cable & harness design and/or printed wiring board design, such as rigid printed circuit board or flex-based circuit board for our interconnect solutions.

Our engineers possess a strong foundation and knowledge of space vehicle, spacecraft, and/or payload logical architecture. From proposal creation to designing schematics to working hands on in the harness lab to watching a satellite being pushed onto a truck and taken to the launch site, you’ll have a hand in it all. 

Strong communication and organizational skills are critical to success in this position, along with the ability to build strong relationships, collaborate in a cross-functional environment, and utilize problem-solving skills to proactively identify and manage risks and opportunities.

• Generation of subsystem or unit-to-unit electrical block diagrams.
• Definition and documentation of signal connectivity through cross functional coordination with system, subsystem, and product engineers for spacecraft harness or printed wiring board design.
• Selection of harness components and hardware, such 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 board form factor, schematic capture, board stack determination, 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 the development of harness test scripts for cable testers.
• Participation of critical programmatic milestones (Preliminary Design Reviews, Critical Design Reviews, etc.) including the preparation of data packages, conduction of design reviews, and closure of any liens from the Milestone Decision Authority (MDA).
• Support assembly and testing of FlatSat and flight harnesses while reporting on cost and schedule performance.
• Capture of as-built, made on assembly mockup harness builds to produce 2D/3D formboards.
• Support with the creation, maintenance, or update of harness design, assembly, and test standards and command media.
• Support in proposals and business development efforts as the responsible engineering authority (REA).
• Management of external suppliers and subcontractors for harness and printed circuit board delivery.
