Cssmerge Staff Engineering Technician responsible for building, retrofitting, and readiness of development vehicles. Independently debug complex mechanical, electrical, and firmware issues and collaborate with engineering teams.
Responsibilities
We are hiring a Senior Engineering Technician to own the build, retrofit, and readiness of our development vehicles. This is not a standard vehicle technician role; you will take a vehicle from bare platform through installation, functional check, and sign-off, often before a documented procedure exists. You must be capable of working independently to debug complex, cross-disciplinary failures across mechanical, electrical, and firmware layers when documentation is sparse. You will work closely with our engineering teams, translating frontline issues into actionable feedback. This is a full-time, in-person opportunity in our SF HQ for builders who thrive in unstructured, fast-paced environments.
Take vehicle builds from bare platforms through installation, functional check, and sign-off Integrate custom compute units and complex sensor stacks.
Make routing, mounting, grounding, and serviceability decisions.
Build prototype cable harnesses, and verify terminations, pinout, and continuity.
Lead vehicle retrofits and maintain as-built records Independently execute complex hardware-software bring-up and debug sessions
Triage and resolve frontline engineering issues, identifying root causes for intermittent electrical or firmware faults.
Write work instructions and checklists for junior technicians Coordinate scheduled service and vehicle preparation for test Train junior technicians and review their work.
Collaborate closely with cross-functional engineering teams to drive design-for-serviceability improvements.
Help maintain our shop space, where assembly of production parts happens, keeping the space clean and organized.
Qualification
Ability to read wiring diagramsProficiency with handExperience with autonomous vehicles
Required
5+ years of hands-on experience in vehicle integration, automotive or EV service, electromechanical assembly, or fabrication.
Proven ability to work independently and troubleshoot from first principles in unstructured engineering environments.
Experience debugging cross-disciplinary systems (mechanical, electrical, and software) at a systems-integration level.
Ability to read wiring diagrams, schematics, mechanical drawings, and BOMs, and to flag a discrepancy rather than build around it.
Working knowledge of vehicle electrical systems, including low-voltage power distribution, fusing, grounding, connectors, and CAN bus.
Proficiency with hand, shop, and automotive tools, and with a multimeter, oscilloscope, and soldering iron.
Experience writing procedures or documentation that others work from.
Ability to handle many simultaneous projects and tasks.
Must be able to safely lift up to 50lbs and stand for long periods of time.
Experience with autonomous vehicles, EV, motorsport, aerospace, or heavy equipment is a plus.
High-voltage safety training for EV work is a plus Experience with CAN tooling, vehicle bus analysis.
Command line or Linux experience is a plus Experience with Solidworks or other CAD software is a plus.
