We’re looking for a Prototype & Test Engineering intern to help bring a new electromechanical product to market. You’ll be part of a small, mission-driven team and work on multiple parts of the system. You’ll build and deploy prototypes to users, run critical tests, and support failure analysis in hardware-software integrated systems.

This role requires being on-site 5 days in our San Francisco office. It will last 8-10 weeks (fall 2026).

What you'd do

Build and test complex electromechanical systems for a new product, including sensors, pumps, and electronics.
Collaborate with product team to deploy systems to real users
Collaborate with sensor, mechanical, electrical, and software engineering to review sensor data and field feedback, identify root cause of issues, and determine corrective actions
Reproduce and characterize failure cases on the bench to confirm root cause and validate that corrective actions hold.
Track and report findings from troubleshooting to the engineering and product team.
Engineering background with ability to troubleshoot complex systems.
Experience with hands-on prototyping of mechanical and electrical systems.
Experience using lab and diagnostic tools such as multimeters, oscilloscopes, and command-line utilities to characterize and debug hardware-firmware systems.
Familiarity with AI tools (e.g.
Claude) for debugging, scripting, or documentation is a plus.
Strong written and verbal communication skills.
BS or expected BS in engineering or equivalent. MS preferred.
