  • Give feedback to and work closely with cross-functional and direct team members.
  • Contribute outside of your field, participating in design reviews, building user interfaces, and teaching.


  • Project history demonstrating expertise in robotics and automation firmware development.
  • Expertise at every stage of firmware development: design, implementation, testing, deploying and debugging
  • Fluency in C / C++
  • Experience developing software on an embedded real time operating system (FreeRTOS a plus)
  • Familiarity with CAN, modbus, I2C, SPI, RS485, and similar
  • Experience implementing build tools and unit tests
  • Troubleshooting integrated systems and large electromechanical devices, including the use of tools such as oscilloscopes and multimeters.
  • Juggler of challenging tasks with limited documentation and tight deadlines
  • A lovable human being with an attitude and style
  • Someone looking for significant equity ownership in a high growth company
  • Someone that is open to working on-site (following appropriate safety procedures) in San Francisco for testing and debugging. Remote work encouraged when possible during COVID WFH regulations.
