What You’ll Do

• Own small and medium-sized hardware projects from initial problem definition through design, prototyping, testing, documentation, and release.
• Design and improve mechanical components and assemblies for our robots and supporting hardware, including enclosures, brackets, mounts, junction boxes, cable-management components, and manufacturing tools.
• Create and maintain CAD models, engineering drawings, BOMs, assembly instructions, and other documentation needed to turn prototypes into repeatable builds.
• Design, assemble, and debug electrical systems such as wiring harnesses, power and communications assemblies, breakout boxes, interface boards, and diagnostic tools.
• Develop fixtures and test equipment for manufacturing, incoming inspection, quality control, hardware validation, and troubleshooting.
• Work closely with our manufacturing and operations teams to identify recurring problems and develop tools, design changes, and processes that make our robots easier to build and test.
• Support robot builds and hardware bring-up in our Brooklyn lab, particularly when new designs or unexpected issues require engineering judgment.
• Help establish lightweight but effective hardware-development practices, including design reviews, revision control, test procedures, build documentation, and release processes.

What You Bring

• A degree in mechanical engineering, electrical engineering, mechatronics, robotics, or a related discipline—or equivalent experience demonstrated through things you have designed and built.
• Experience designing, building, and debugging electromechanical systems through internships, project teams, research, professional work, or substantial personal projects.
• Proficiency with a mechanical CAD package such as SolidWorks, Onshape, Fusion 360, or a similar tool.
• Experience creating physical prototypes using techniques such as 3D printing, machining, sheet-metal fabrication, laser cutting, or basic shop tools.
• Comfort working with electrical schematics, wiring diagrams, connectors, sensors, power distribution, and low-voltage electrical systems.
• Hands-on experience using common lab and shop equipment, such as multimeters, oscilloscopes, bench power supplies, soldering tools, crimpers, and basic fabrication equipment.
• A systematic approach to testing and troubleshooting, with the ability to move from symptoms to root cause rather than relying on trial and error alone.
• Strong written and verbal communication skills, particularly when documenting designs, explaining tradeoffs, or coordinating work across teams.

Bonus Skills

• Experience with robots, industrial automation, autonomous vehicles, manufacturing equipment, or other complex electromechanical products.
• Experience designing wiring harnesses, cable assemblies, electrical enclosures, or industrial control panels.
• Familiarity with industrial communications and interfaces, particularly Ethernet, CAN, and USB.
• Experience designing simple PCBs, interface boards, or microcontroller-based test devices.
• Familiarity with Python, embedded programming, Linux, or scripting for test automation and hardware diagnostics.
• Experience with design for manufacturing and assembly, tolerance analysis, sheet-metal design, environmental sealing, thermal management, or ruggedized hardware.
• Experience working with machine shops, contract manufacturers, fabrication vendors, or component suppliers.
• A portfolio, project page, or collection of photographs showing hardware you have personally designed, built, tested, or repaired.

Expected Compensation
