This is a highly hands-on role focused on designing, building, and validating harnesses that operate in demanding environments. You'll work across electrical, mechanical, and test teams to deliver reliable, lightweight, and production-ready harness solutions, while also contributing to test infrastructure like fixtures and system test racks. This role requires speed, autonomy, and a strong bias toward execution, Harness Design & Ownership * Own end-to-end design of UAV wiring harnesses: concept prototype production. * Design for power, high-speed signals, RF, and mixed-signal systems under tight size, weight, and power constraints * Rapidly iterate on harness layouts, routing, and packaging with mechanical and electrical teams * Full harness design including connectors, shielding strategies, wire types, and protection schemes for harsh environments (vibration, temperature, EMI) * Drive design decisions with a focus on reliability, manufacturability, and field serviceability Build, Integration & Validation * Lead bring-up and integration of harnesses into full vehicle systems * Define and execute validation: continuity, insulation resistance, shielding effectiveness, and system-level functional checks. * Identify and fix issues quickly during integration and flight test cycles Production & Scaling * Work directly with technicians and vendors to transition harnesses from prototype to production * Define build processes, QA checks, and acceptance criteria * Troubleshoot production issues (opens/shorts, intermittent faults, connector failures, shielding gaps) * Continuously improve harness designs based on production and field feedback Failure Analysis & Debugging * Own root-cause analysis of electrical interconnect failures in lab, production, and field * Use oscilloscopes, DMMs, hipot testers, and other tools to diagnose complex issues * Drive corrective actions quickly and prevent recurrence Documentation * Create and maintain harness drawings, pinouts, and build docs * Keep documentation lightweight, accurate, and usable by technicians * Maintain revision control without slowing down development speed ## Related Videos - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [How To Test A Ball of Mud](https://www.wearedevelopers.com/videos/173-how-to-test-a-ball-of-mud) - [Empowering Democratic Processes: Building a Hybrid Voting Platform](https://www.wearedevelopers.com/videos/1163-empowering-democratic-processes-building-a-hybrid-voting-platform) - [How I Built QA from Scratch in a Scaling Startup - no fluff real life story](https://www.wearedevelopers.com/videos/2041-how-i-built-qa-from-scratch-in-a-scaling-startup-no-fluff-real-life-story) - [Reusing apps between teams and environments through Containers](https://www.wearedevelopers.com/videos/107-reusing-apps-between-teams-and-environments-through-containers) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) ## Related Articles - [Should senior developers refuse interview coding challenges?](https://www.wearedevelopers.com/magazine/29-should-senior-developers-refuse-interview-coding-challenges) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [What is a Test Plan: Guide to Test Planning](https://www.wearedevelopers.com/magazine/191-what-is-a-test-plan-guide-to-test-planning) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [How to Write a CV and Interview if You Don't Fully Qualify For The Job](https://www.wearedevelopers.com/magazine/183-how-to-write-a-cv-and-interview-if-you-don-t-fully-qualify-for-the-job)
