About The Position

Katalyst is seeking a 3D Harness Engineer to own spacecraft harness design and 3D routing. This role involves translating electrical schematics and interconnect requirements into harness routing through integration and test. The engineer will develop detailed 3D harness routing models in SolidWorks, create parametric models of harness and interconnect components, and develop wire lists, connector pin maps, drawings, and harness specifications. The position requires defining harness architectures that meet electrical and environmental requirements and collaborating with electrical and mechanical teams to deliver reliable interconnect systems. Support for qualification, acceptance testing, vehicle integration, troubleshooting, and design iteration is also expected.

Requirements

Bachelor's degree in Mechanical Engineering, Electrical Engineering, or a closely related engineering discipline from an accredited institution.
3+ years of professional experience with 3D CAD harness routing and hands-on CAD library management.
Expert-level proficiency with SolidWorks, including 3D Routing, parametric part and assembly modeling, drawing detailing, and SolidWorks PDM Professional.
Strong understanding of electrical and mechanical harness design principles, including wire and cable selection, connectorization, pin mapping, grounding, shielding, voltage drop, controlled impedance, and EMI/EMC considerations.
Experience developing complex interconnect systems and translating wiring diagrams, schematics, and electrical requirements into complete 3D designs and manufacturing documentation.

Nice To Haves

Experience designing harnesses for spacecraft, aircraft, robotics, or similarly complex aerospace or electromechanical systems.
Working knowledge of applicable harness workmanship and design standards.
Experience with SolidWorks Electrical Schematic and bidirectional electrical-to-mechanical design workflows.
Strong understanding of electrical failure modes and mitigation techniques, including interference, voltage drop, thermal effects, crosstalk, grounding, bonding, and shield termination.
Knowledge of industry standards and regulations related to wire harness design, such as IPC/WHMA-A-620 and/or NASA-STD 8739.4A
Experience automating harness design workflows using SQL, Python, or other scripting languages.
Familiarity with radiation effects on avionics, cabling, and materials is a plus.

Responsibilities

Own spacecraft harness design and 3D routing of spacecraft harness, translating electrical schematics and interconnect requirements into harness routing through integration and test.
Develop detailed 3D harness routing models in SolidWorks, including cables, wires, connectors, backshells, clamps, and other harness hardware, and maintain the associated routing libraries within a PDM-managed environment.
Create parametric 3D models of harness and interconnect components, including connectors, backshells, clamps, brackets, and other hardware.
Develop accurate models from drawings, specifications, or physical hardware when existing CAD models are not available.
Develop wire lists, connector pin maps, drawings, and harness specifications while maintaining traceability between electrical design intent, 3D routing, and manufacturing documentation.
Define harness architectures that meet electrical and environmental requirements, including current capacity, voltage drop, grounding, bonding, shielding, EMI/EMC, thermal effects, radiation exposure, and space charging considerations.
Work across electrical and mechanical teams to trade routing configurations and deliver reliable, testable, and cost-effective interconnect systems.
Support qualification, acceptance testing, vehicle integration, troubleshooting, and design iteration.
