R&D Engineering Technician

Responsibilities

• In building robots for the home, we are tackling a true grand challenge in robotics: dexterous mobile manipulation in unstructured environments. To make this possible, we are building across the entire robotics stack, and a lot of that work happens at the bench.
• Assemble, wire, and bring up robotic systems and subsystems including actuation and perception hardware, following engineering drawings and work instructions
• Execute test plans and procedures developed by engineers; collect, log, and organize test data
• Build, maintain, and improve test fixtures and jigs
• Run standard test equipment (oscilloscope, multimeter, logic analyzer) under engineering direction, to triage and debug issues
• Support cross disciplinary triage spanning mechanical, electrical, firmware, and software systems, escalating findings to the responsible engineers
• Document build logs, write standard operating procedures, and surface recommendations to engineers
• Perform soldering, crimping, rework, and light fabrication to support prototyping and repair
• Maintain lab equipment, tools, inventory, and consumables; keep the workspace organized, calibrated, and safe
• Provide feedback and work on improvements to robot assembly, bringup, and QA processes
• Use basic scripting (Python) to run test routines or parse data where it speeds the work

Requirements

• 2+ years of hands on experience building and testing robots (or complex electromechanical systems - those are robots too!)
• Ability to read and work from schematics, mechanical drawings, BOMs, and work instructions
• Comfort with soldering, crimping, hand tools, and basic mechanical/electrical fabrication and assembly
• Familiarity with standard diagnostic tools (oscilloscope, multimeter, logic analyzer)
• Strong, detail-oriented record keeping and a habit of clear documentation
• Comfort working in a fast-moving prototype environment
• Exposure to protocols including CAN, Ethernet, USB, MIPI
• Hands on experience with actuators, cameras, microcontrollers
• Soldering and rework to IPC standards
• Comfortable with agentic coding tools (Claude Code, Codex, etc.)
• Prior experience in a robotics startup
• Even if you don't meet every single requirement, we encourage you to apply. Studies show that women and underrepresented groups often hold back unless they meet 100% of the criteria - we don't want that to be the reason we miss out on great talent.
