Electrical Engineering Intern

About the Company

Arn Autonomy is building autonomous, non-humanoid robotic systems to construct infrastructure in extreme, unstructured environments, starting with next-gen construction job sites. Our vision is to disrupt the $16 trillion global construction industry by pioneering a new Deep Tech philosophy that blends robotics, AI, and systems engineering at the frontier. Our flagship product, GRID, is an autonomous rebar-tying robot deployed with rebar and concrete contractors on live job sites.

About the Role

We're seeking an Electrical Engineer Intern to join the team building GRID, our rebar-tying mobile robot. You will design, prototype, test, and integrate multi-layer PCBAs for a robot that works on live construction sites, and you will see your boards go from schematic to running hardware in the field. This is a hands-on, cross-disciplinary role: you'll work alongside our mechanical, software, and manufacturing teams, with mentorship from senior engineers and a high degree of autonomy. Interns who grow with us may have opportunities to take on larger projects as GRID scales.

Responsibilities

• PCBA Design & Prototyping: Design and prototype multi-layer PCBAs for GRID's subsystems, including motor drives, sensor interfaces, power distribution, and test fixtures

• Bring-Up & Debug: 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

• 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

• Testing & Validation: Build test setups and procedures, and take part in field testing of GRID on construction job sites

• Documentation: Deliver schematics, layout reviews, engineering studies, test results, and architecture documents so designs are traceable and reproducible

• Design Reviews: Generate and present design concepts, and run design reviews with team members

• Learning from Senior Engineers: Work alongside mentors to develop reliable electrical designs for a range of robotic tasks

• Role Variability: This internship covers design, assembly, manufacturing, and test. Your mix of responsibilities will depend on the project and team, giving you broad exposure to robotics hardware development

Required

• 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, so you can commit to the internship full time and in person

• 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

This is an in-person role, five days a week, in the San Francisco Bay Area. You must be based in the Bay Area or willing to relocate for the internship.

Preferred

• 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

Benefits

Why join us:

• 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

We're a startup moving fast, and being in the room together is how we build.

• Kaiser Gold HMO health plan

• Relocation support

• Daily lunches

• Flexible PTO

• Dog pets
