Qualifications

• B.S. in Electrical Engineering, Computer Engineering, or a closely related field (completed, or completing within the next year).
• 0 to 3 years of professional experience. Internships, co-ops, senior design, and serious personal or team projects count.
• Hands‑on soldering and electronics assembly experience.
• Comfortable with basic lab equipment: oscilloscopes, DMMs, and bench power supplies.
• Basic C/C++ or Python, and some experience with microcontrollers (STM32, Arduino, Teensy, or similar).
• Good documentation habits and clear written and verbal communication.

• Run bench tests on motors, motor drivers, sensors, and power boards.
• Write simple bring-up and test code in C/C++ or Python.
• Debug boards at the bench and on the robot.
• Assemble and rework small boards in house: fine-pitch SMD soldering, solder paste and stencils, reflow, and pick-and-place.
• Build wiring harnesses, cables, test fixtures, and component kits for each robot build.
• Inspect incoming boards and parts, and help with full robot builds and system checkout.
• Track parts, lead times, and BOMs so builds don’t wait on missing parts.
• Keep clear records: test reports, build logs, and revision history.
• Learn schematic and PCB design from our senior engineering mentors and design partners.
• Take on more of the hardware design as you build your track record.
