Job Description

Design robust, serviceable, and manufacturable wire harnesses and connector systems for electronic products across prototype through high-volume production, ensuring electrical performance, mechanical reliability, testability, and cost‑effective assembly while collaborating closely with electrical, manufacturing, test, and supplier teams.

Our Team

We are part of a dynamic engineering division focused on innovation in connector systems and electronic components. Our team blends cross‑functional expertise in design, manufacturing, and quality assurance to deliver industry‑leading solutions that meet customer needs.

What You Will Do

• Architect end‑to‑end wire harness and connector solutions that meet signal, power, mechanical, environmental, and regulatory requirements while optimizing manufacturability and serviceability.
• Define connector selection, pinouts, wire gauge and insulation, shielding, shielding terminations, sealing/strain relief, and routing strategies that ensure signal integrity, EMI control, and long‑term reliability.
• Produce detailed harness schematics, assembly drawings, cut‑lists/BOMs, harness build procedures, and supplier‑ready documentation that enable repeatable production and test.
• Create and release detailed CAD models, engineering drawings with GD&T, and BOMs that enable repeatable supplier builds and in‑house assembly.
• Ensure product lines meet Mil‑spec qualifications, during yearly audits, design changes and process improvements.
• Collaborate with vendors, customers, and shop personnel to resolve design and production issues.
• Mentor junior engineers and help maintain interconnect part libraries, standard connector families, and drawing/templates to accelerate new product development.

Who You Are (Basic Qualifications)

• Bachelor’s degree in Electrical Engineering, Mechanical Engineering, or related discipline.
• 3+ years of mechanical design experience in electronics product development or aerospace & defense environments.
• Proficient with 3D CAD (SolidWorks, Creo, or equivalent) and generating production‑ready 2D drawings with GD&T.
• Strong understanding of tolerancing, materials, coatings, and mechanical design for harsh environments.
• Familiarity with interconnect and assembly standards and inspection criteria (e.g., IPC/WHMA‑A‑620, UL/CSA requirements) and experience supporting test plans and manufacturing release.
• Experience creating clear engineering documentation (BOMs, change notices) and working with cross‑functional teams to release production designs.

What Will Put You Ahead

• 3+ years of hands‑on wire harness/cable assembly and connector design experience in electronics product development or electronics manufacturing.
• Experience with high‑volume manufacturing scale‑up, supplier qualification, and process control for cable harness production.
• Practical knowledge of crimping, soldering, overmolding, potting, shielding practices, and common connector types (board‑mount, circular, rectangular, power, FFC/FPC) used in electronic products.
• Background in EMI/EMC mitigation for cable/connector systems, including shielding topology, drain wires, and connector gaskets.
• Experience specifying and validating harnesses for harsh environments (temperature cycling, ingress protection, salt spray, vibration/shock) and supporting regulatory or industry certifications.
• Experience with PDM/PLM systems, structured change control (ECOs), and scripting/automation to generate BOMs and harness cut‑lists.
• IPC/WHMA‑A‑620 design experience, supplier auditing experience, or prior work in automotive/aerospace/industrial electronics domains.
