Associate Electrical Engineer - Vehicle Wiring

About the role

We are seeking an Associate Electrical Engineer to join our electrical team and grow into ownership of the high-voltage wiring that powers our self-propelled battery-electric railcars and vehicles. This is a full-time, 100% in-office role based in St. Louis, MO.

Responsibilities

• Harness Build & Installation: Build wire harnesses, assemble panels and backplanes, and install high-voltage vehicle wiring on the shop floor, working from run lists, schematics, and BOMs — learning the product, its failure modes, and correct installation practice by doing the work alongside experienced technicians and engineers.
• High-Voltage Safety Practice: Work safely around high-voltage systems — proper isolation, PPE, and lockout/tagout — and flag hazards that could delay a build or compromise safety.
• Schematic & Drawing Interpretation: Read and interpret electrical schematics, wire run lists, and technical drawings, and correlate them accurately to the physical build.
• Harness Documentation: Grow into ownership of harness documentation — wire run lists, harness drawings, connector and pinout definitions, and revision control — so the next person can build and service the vehicle correctly.
• Outsourcing & Vendor Coordination: Manage the outsourcing of harness fabrication — preparing the documentation package, sourcing and qualifying suppliers, and validating delivered work against spec.

Requirements

• Bachelor's degree in Electrical Engineering or a closely related field — or equivalent hands-on high-voltage and vehicle-wiring experience in lieu of the degree.
• Foundational understanding of high-voltage electrical systems and safe practice around them, including proper isolation, PPE, and lockout/tagout.
• Ability to read and interpret electrical schematics, wire run lists, and technical drawings, and to correlate them to a physical build.
• Hands-on aptitude with vehicle wiring and harness assembly — comfortable on the shop floor with fabrication tools and electrical diagnostic equipment, or a clear track record showing you will get there quickly.
• Attention to proper installation and documentation methods — doing the wiring right and recording it right so the next person can build and service it.
• Willingness to spend the first six months hands-on as a technician before growing into the engineering and documentation scope.
• Willingness to expand into technical areas beyond your area of expertise; ability to develop innovative and novel approaches.
• Open-minded and comfortable working in a teaming environment as an individual contributor.
• Fluent in both written and verbal English.
• U.S. Person (immigration or work visa sponsorship will not be provided).

Qualifications

• Exposure to EV powertrains or high-voltage battery management systems (BMS) — our railcars are battery-electric vehicles, so EV and HV experience translates directly.
• Familiarity with wire-harness engineering tooling — harness drawing and documentation software, connector and pinout definition, and revision control of electrical documentation.
• Experience working with external fabrication vendors and suppliers — preparing a documentation package, sourcing, and validating delivered work.
• Familiarity with industrial communication protocols such as CAN bus.
• Internship, co-op, or academic-project experience with vehicle wiring, high-voltage systems, or hands-on electrical fabrication.
• Experience with electric vehicles, autonomous rail systems, or other unmanned systems.

Benefits

• Medical coverage: We cover 100% of employee medical premiums, plus low-cost dental and vision options.
• Vacation: Full-time employees enjoy unlimited paid time off.
• Equity: Full-time employees receive equity in the company.
• Parental leave: New parents receive paid time off to spend quality time with their family.

Pay

Base salary: $60,000 - 80,000 plus equity.
