Traysar is the world's first subterra defense tech company building autonomous platforms to penetrate, map, and secure subterranean environments.
About Traysar Traysar was founded in 2025 by second time tech founders, recipients of the Israel Defense Prize, and engineers from elite military units, the Boring Company and SpaceX. Backed by Lux Capital and the founders of Anduril, the leading autonomous defense company, Traysar is reclaiming Western Deterrence by developing and deploying technologies for the 5th domain of warfare: the underground. Job Summary Traysar is seeking a highly motivated and experienced founding Electrical Engineer to join our team. The machines you design and are responsible for getting built will be used to destroy hundreds of miles of tunnels currently used for terrorist activities. The candidate will work with a mechanical engineer (hydraulics) and report to an electromechanical engineer (team lead). RESPONSIBILITIES: - End-to-end ownership of motor design, power distribution, and machine control systems. - Development and tuning of motor controllers, actuators, drive logic, and safety interlocks. - Production of detailed schematics, wiring diagrams, and harness layouts. - Selection of motors, drivers, batteries/power supplies, and all electrical components. - Build and test control loops, sensor interfaces, and low-level firmware. - Validation of electrical systems during prototype builds and field tests; troubleshooting and system optimization. - Close collaboration with the electro-mechanical lead to implement subsystem requirements and ensure seamless integration with hydraulics, chassis, and autonomy modules. BASIC QUALIFICATIONS: - 7+ years of work experience. - Degree in any field of engineering or equivalent training. - Experience with 3D CAD modeling and 2D drawing specifications. - Experience with heavy equipment hydraulic systems (tractors, excavators, mining systems). PREFERRED SKILLS AND EXPERIENCE: - Strong background in motor control, power electronics, and high-current distribution for mobile machinery. - Experience designing electrical and control systems for hydraulic or heavy-equipment platforms. - Proficient in schematic design, wiring and harness development, and integrating motors, drivers, sensors, and low-level control firmware. - Comfortable debugging electrical systems under load and working with ruggedized, vibration- and shock-tolerant components. - Able to own the full electrical stack from concept through field testing and integrate tightly with mechanical and hydraulic subsystems. If there is a fit, we'll schedule two technical interviews. For the second one you will prepare a short presentation about something you built that you are proud of. Those who pass the technical interviews will proceed to a third and final interview on-site.
