Electrical Engineering Intern

Arn Autonomy•South San Francisco, CA
•Onsite

About The Position

Arn Autonomy is seeking an Electrical Engineer Intern to join the team building GRID, their rebar-tying mobile robot. The intern will design, prototype, test, and integrate multi-layer PCBAs for a robot that operates on live construction sites. This is a hands-on, cross-disciplinary role involving collaboration with mechanical, software, and manufacturing teams, with mentorship from senior engineers and a high degree of autonomy. Interns who perform well may have opportunities to take on larger projects as GRID scales.

Requirements

  • Completed a bachelor's or graduate degree from an accredited program in Electrical Engineering, Robotics, Mechatronics, Computer Engineering, or a similar field, with no ongoing coursework.
  • Working knowledge of circuit design theory and core electrical engineering principles.
  • Hands-on experience with oscilloscopes, DC power supplies, and multimeters from coursework, labs, or personal projects.
  • Ability to analyze problems and work with teammates to find well-reasoned solutions.
  • A self-starter with proven examples of self-directed learning, who stays productive with minimal support.
  • Available to work full-time (40 hours/week) for an internship lasting at least six months.
  • Authorized to work in the United States.
  • Must be based in the Bay Area or willing to relocate for the internship.

Nice To Haves

  • Experience with PCB design software such as Altium, KiCad, or Eagle, including multi-layer layout.
  • Prior prototyping or firmware experience on microcontrollers (C/C++ or similar).
  • Basic scripting in Python or MATLAB for test automation and data analysis.
  • Familiarity with motor drives, battery and power systems, CAN or other field buses, and sensor interfacing.
  • Exposure to mobile or outdoor robotic platforms, or to rugged, environmentally sealed electronics.
  • Prior internship, co-op, or substantial project experience (robotics clubs and competition teams count).
  • Ability to rapidly learn, evaluate, and adopt new AI tools and platforms as project needs evolve.

Responsibilities

  • Design and prototype multi-layer PCBAs for GRID's subsystems, including motor drives, sensor interfaces, power distribution, and test fixtures.
  • Assemble, power up, and debug boards on the bench using oscilloscopes, DC supplies, and multimeters.
  • Perform root cause analysis on issues found during bench testing and system integration.
  • Work with mechanical and software engineers to integrate electronics, wiring, and harnesses into field-ready assemblies that withstand outdoor dust, vibration, temperature swings, and weather.
  • Build test setups and procedures, and take part in field testing of GRID on construction job sites.
  • Deliver schematics, layout reviews, engineering studies, test results, and architecture documents so designs are traceable and reproducible.
  • Generate and present design concepts, and run design reviews with team members.
  • Work alongside mentors to develop reliable electrical designs for a range of robotic tasks.
  • This internship covers design, assembly, manufacturing, and test. The mix of responsibilities will depend on the project and team, giving broad exposure to robotics hardware development.

Benefits

  • Work on a real product: your designs ship on GRID, a robot deployed on live construction job sites.
  • Hands-on experience in electrical design, integration, testing, and debugging on real hardware.
  • Collaborate with mechanical, software, and manufacturing engineers in a small, fast-moving team.
  • Mentorship and professional development from senior engineers.
  • Kaiser Gold HMO health plan
  • Relocation support
  • Daily lunches
  • Flexible PTO
  • Dog pets
