Avionics Engineer

At TerraFirma, we’re redefining how the world moves earth for construction. Founded by former SpaceX engineers and backed by Bain Capital Ventures, TerraFirma is automating construction to make it faster, cheaper, and safer. Job Overview You will design and maintain the electrical systems that enable reliable remote operation of construction equipment, including wiring harnesses, circuits, and system integration for drive‑by‑wire machines in rugged outdoor environments. The role is hands‑on, spanning fabrication, lab and field troubleshooting, and vendor collaboration to streamline builds. Responsibilities Design wiring harnesses, circuits, and systems to enable reliable control of drive‑by‑wire machinery in high vibration, dirty, outdoor environments. Drive improvements to designs to simplify builds and installs, reduce wiring ambiguity, add practical test points, and make field service faster and more repeatable. Support vehicle builds and retrofits by unblocking installation issues, improving harness routing/packaging, and iterating rapidly based on shop and field feedback. Create and maintain wiring diagrams, harness drawings, assembly/installation procedures, test procedures, bills of materials, and suitable alternates to eliminate uncertainty. Assemble and install harnessing and circuits for development testing and operational use in the field. Use measurement equipment to troubleshoot electrical systems on the bench and in the field; own root‑cause investigations, implement immediate fixes, and drive sustainable long‑term solutions. Develop and maintain working relationships with manufacturers to streamline production and improve build and install quality over time. Basic Qualifications B.S. in Electrical or Computer Engineering. Practical experience working on electrical systems. Preferred Skills & Experience Circuit design fundamentals and component selection experience. Experience designing and qualifying systems for high vibration and/or outdoor environments. Experience using electrical measuring equipment (oscilloscope, multimeter, signal analyzer, etc.). Experience building wiring harnesses and assembling circuit boards (preferably to industry or other recognized standards). Strong understanding of fail‑safe design principles. Experience designing, setting up and debugging computer networks (Ethernet, CAN bus, Cellular, WIFI, etc.). Experience creating clear installation/test documentation for technicians and partners (photos, diagrams, checklists, acceptance tests). Additional Requirements Comfortable with working in a fast‑paced startup environment. Must be willing to relocate to Austin, TX if not within commuting distance. Must be willing to work extended hours or weekends when needed to support critical deadlines. Compensation & Benefits Base compensation will vary based on factors such as relevant experience and education. Salaries and leveling will be determined on a case‑by‑case basis if an offer is extended. Our total compensation package also includes equity in TerraFirma.
