Cable Harness Engineer

Job Details

Job ID: 11024

New ideas are all around us, but only a few will change the world. That’s our focus at JPL. We ask the biggest questions, then search the universe for answers—literally. We build upon ideas that have guided generations, then share our discoveries to inspire generations to come. Your mission—your opportunity—is to seek out the answers that bring us one step closer. If you’re driven to discover, create, and inspire something that lasts a lifetime and beyond, you’re ready for JPL.


Located in Pasadena, California, JPL has a campus-like environment situated on 177 acres in the foothills of the San Gabriel Mountains and offers a work environment unlike any other: we inspire passion, foster innovation, build collaboration, and reward excellence.




As a Cable Harness Engineer you will be working for JPL’s Spacecraft Mechanical Engineering Section, which is responsible for the architecture of mechanical engineering designs and solutions that enable unprecedented missions and science acquisition.  You will work with a team that leads the development of mission enabling technology and end-to-end mechanical systems for all JPL projects and missions.


  • Provide cable engineering expertise to the harness design, fabrication and integration.
  • Assure the integrity of the harness from inception through delivery.
  • Investigate, plan, design and develop harness to meet technical requirements in compliance with programmatic constraints including cost and schedule.
  • Support senior engineers and be a part of design teams to develop requirements, design, oversee fabrication and integration of harnesses for a variety of JPL spacecraft and instrument flight projects.
  • Deliver and provide periodic status updates to project engineers and group supervisor as required.
  • Pro-actively communicate and co-ordinate with engineers, designers, analysts including multiple other subsystems to negotiate interfaces.
  • Interact with others to perform cross-disciplines trade studies and analysis of alternatives through application of discipline-specific expertise.
  • Prepare and present harness subsystem design, architecture and implementation plans at various design team meetings and reviews. 


Required Skills:

  • Bachelor's degree in Mechanical, Electrical, Material Science, Aerospace Engineering or related technical discipline with typically a minimum of 3 years of related experience; Master's degree in similar disciplines with a minimum of 1 year of related experience; or PhD in similar disciplines with 0 years related experience.
  • Has broad knowledge in one or more of the following areas:
    • Develop requirements including verification & validation methods at the subsystem level.
    • Communicate and negotiate interfaces with all other sub-systems (Structural, Thermal, Propulsion, Electrical Systems Engineering, Avionics, etc.).
    • Architect harness design to meet project and technical requirements.
    • Detailed design of flight and ground support cable harness assemblies.
    • Prepare and release drawings to fabricate and integrate harnesses.
    • Develop implementation plans and manage cost and schedule for task.
  • Extensive understanding and wide application of principles, theories, concepts and techniques in in design development of wire harness designs including:  ability to interpret pertinent harness requirements from electrical wiring schematics to create wire lists, designing Faraday enclosures, create harness assembly drawings, select parts and materials for flight harness assemblies, perform trade studies, prepare mass estimates, coordinate fabrication, assembly, testing and qualification of hardware.
  • Has extensive knowledge of industry and/or academic practices and standards across a range of applications related to electrical connectors and wire for spaceflight applications, including Mil-Aerospace standards such as MIL-C-38999, MIL-C-24308, Mil-83513, and MIL-STD-1553. Pertinent practices include selection of wiring based on current de-rating, voltage drop analysis, shielding effectiveness, temperature environment, outgassing and mechanical strength.

Desired Skills:

  • Detailed and hands‐on based knowledge of fabrication processes and workmanship criteria for flight and ground support harness in accordance with JPL D‐8208, NASA 8739.4 and SAE AS50881 and IPC/WHMA-A-620A.
  • Familiarity with software tools such as NX, Microsoft Access, ECAD tools.
  • Experience with engineering oversight of integration of harnesses on flight hardware.
  • Familiarity with flex printed cables. Experience in developing mechanical harness routing solutions for dynamic applications including across articulated joints and hinged-line deployments.
  • Ability to construct a detailed hardware task plan, managing and executing plan through delivery to customer.
  • Technical expertise in capabilities, selection and qualification of components used in flight spacecraft cable harness designs.  Components include connectors, backshells, wire, contacts, splices, solder, overshields, terminal lugs and coax products.
