Senior Prototype Cabling Engineer

Atomic Machines is building the Matter Compiler™, the first in a new class of AI-native, all-digital manufacturing systems that build working machines directly from code. The Matter Compiler™ is aimed at micro-machines: motors and gears the size of a grain of sand, robots small enough to work inside the body, cooling built directly into the chips that run AI, and the many devices like them that have been waiting on a way to build them. Its first product is PrimeSwitch™, an electromechanical power relay the size of a button battery that carries 150 amps continuous current and opens in 50 microseconds, about a thousand times faster than a conventional contactor. Founded by Jeff Holden — serial entrepreneur, ex-Amazon SVP and Uber’s first Chief Product Officer — the company has raised $250 million to date. Atomic Machines is based in the San Francisco Bay Area, with offices in Emeryville and Santa Clara. About The Role: Atomic Machines is hiring Electrical Integration Engineers (Electromechanical Focus) to design, build, document, and troubleshoot the electrical systems used in our custom manufacturing equipment. You will own the electrical integration of electromechanical modules and subsystems, from selecting and interfacing sensors, actuators, and third-party electronics through first-article build, bring-up, validation, and documentation. Interconnect design is an important part of the work, alongside prototype implementation, fixture development, physical integration and packaging, and troubleshooting across electronics, wiring, firmware, and mechanisms. You will work closely with electrical, mechanical, embedded systems, and manufacturing engineers to turn early prototypes into reliable, repeatable, and serviceable designs. What You’ll Do: • Select and integrate sensors, actuators, third-party electronics, power components, cables, connectors, and communication interfaces. • Design and build prototype interconnects, fixtures, and subsystem test setups. • Collaborate with mechanical engineers on packaging, routing, retention, access, serviceability, and assembly strategy. • Troubleshoot issues spanning electronics, wiring, firmware, configuration, and mechanical behavior. • Create and maintain ICDs, interconnect and cable drawings, work instructions, and bring-up procedures. What You’ll Need: • 5+ years of relevant engineering experience, or equivalent substantial hands-on experience. • Experience building, bringing up, or troubleshooting electromechanical hardware. • Experience with crimping cables • Ability to read schematics, block diagrams, pinouts, interface documents, and component datasheets. • Experience integrating and bringing up sensors, actuators, electronics, and wiring within an electromechanical module or machine. • Experience troubleshooting issues across electronics, wiring, sensors, actuators, and firmware using schematics, datasheets, and common lab equipment (oscilloscopes, logic analyzer, multimeters, etc) • Experience creating and maintaining electrical integration documentation, including ICDs, interconnect diagrams, cable drawings, pin tables, and work instructions. • Hands-on experience building, modifying, and testing prototype wiring, cable assemblies, fixtures, or electromechanical hardware. • Strong documentation and cross-functional communication skills. • A bachelor's degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, Mechatronics, or a related field (associate's, bachelor's, or trade/technical program), or equivalent hands-on experience. Bonus Points For: • Experience with robotics, automation equipment, scientific instruments, or other complex electromechanical systems. • Familiarity with motor control, grounding, shielding, EMI, or ESD. • Experience working with cable vendors, electronics vendors, or contract manufacturers. The compensation for this position also includes equity and benefits.
