Electrical Engineering Intern

About the CompanyArn 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 RoleWe'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. ResponsibilitiesPCBA Design & Prototyping: Design and prototype multi-layer PCBAs for GRID's subsystems, including motor drives, sensor interfaces, power distribution, and test fixturesBring-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 integrationSystem 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 weatherTesting & Validation: Build test setups and procedures, and take part in field testing of GRID on construction job sitesDocumentation: Deliver schematics, layout reviews, engineering studies, test results, and architecture documents so designs are traceable and reproducibleDesign Reviews: Generate and present design concepts, and run design reviews with team membersLearning from Senior Engineers: Work alongside mentors to develop reliable electrical designs for a range of robotic tasksRole 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 RequiredCompleted 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 personWorking knowledge of circuit design theory and core electrical engineering principlesHands-on experience with oscilloscopes, DC power supplies, and multimeters from coursework, labs, or personal projectsAbility to analyze problems and work with teammates to find well-reasoned solutionsA self-starter with proven examples of self-directed learning, who stays productive with minimal supportAvailable to work full-time (40 hours/week) for an internship lasting at least six monthsAuthorized to work in the United StatesThis 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. PreferredExperience with PCB design software such as Altium, KiCad, or Eagle, including multi-layer layoutPrior prototyping or firmware experience on microcontrollers (C/C++ or similar)Basic scripting in Python or MATLAB for test automation and data analysisFamiliarity with motor drives, battery and power systems, CAN or other field buses, and sensor interfacingExposure to mobile or outdoor robotic platforms, or to rugged, environmentally sealed electronicsPrior 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 BenefitsWhy join us:Work on a real product: your designs ship on GRID, a robot deployed on live construction job sitesHands-on experience in electrical design, integration, testing, and debugging on real hardwareCollaborate with mechanical, software, and manufacturing engineers in a small, fast-moving teamMentorship and professional development from senior engineersWe're a startup moving fast, and being in the room together is how we build.Kaiser Gold HMO health planRelocation supportDaily lunchesFlexible PTODog petsArn Autonomy is an Equal Opportunity Employer.
