We are looking for a hands-on Connector & Interconnect Design Engineer to own the full lifecycle of custom electrical interface development - from concept and CAD modeling to drawings, testing, and supplier coordination. This role sits at the intersection of mechanical and electrical engineering, and requires someone who can think in 3D, design for manufacturability, and validate to real-world performance requirements. You will be the technical owner of connector and interface programs, working closely with electrical, mechanical, and manufacturing teams to bring novel interconnect solutions from whiteboard to production. Responsibilities: - Own 3D CAD modeling and 2D detailed drawings for custom connectors, overmolds, and electromechanical interfaces - Design housings, contacts, strain reliefs, and sealing features with a focus on mechanical precision and DFM - Create complete manufacturing packages: GD&T drawings, tolerancing, material callouts, and assembly instructions - Perform connector power calculations: contact resistance, current derating, temperature rise, and mating force analysis - Collaborate with EE to ensure interfaces meet signal integrity, shielding, and power delivery requirements - Develop and execute validation test plans: mating cycles, pull-out force, vibration, thermal cycling, and environmental exposure - Define acceptance criteria, document results, and drive corrective actions - Manage custom connector programs end-to-end: RFQ, supplier selection, tooling milestones, and qualification - Support prototype builds, first article inspections, and bench-level troubleshooting - Maintain engineering documentation, BOMs, and revision history in PLM systems Requirements: - Bachelor's or Master's degree in Mechanical Engineering, Electrical Engineering, or related field - 5+ years of experience in connector design, electromechanical packaging, or interconnect engineering - Strong 3D CAD proficiency (CATIA, SolidWorks, Creo, or equivalent) - you will be in CAD every day - Demonstrated experience designing custom components: housings, overmolds, contacts, or electromechanical assemblies - Ability to create complete, manufacturing-ready 2D drawings with proper GD&T - Solid understanding of connector electrical fundamentals: current rating, contact resistance, derating, and power dissipation - Experience developing validation test plans and executing qualification testing - Comfortable working with external suppliers and contract manufacturers across the full development cycle - Hands-on mindset - you prototype, test, and troubleshoot hardware yourself Bonus Qualifications: - Experience with a wide variety of connector technologies and contact interface types - Background in robotics, defense, medical devices, aerospace, or other precision electromechanical systems - Familiarity with injection molding, insert molding, and overmold design for production - EVT/DVT build support experience in a hardware startup environment - Exposure to reliability engineering: FMEA, Weibull analysis, or accelerated life testing - Familiarity with PLM tools (Enovia, Windchill, Agile, or similar) The US base salary range for this full-time position is between $145,000 - $200,000 annually. The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.
