The job description

Tech stack. C programming fundamentals, microcontroller basics (GPIO, timers), UART debugging, Git workflows, basic lab equipment (multimeters, oscilloscopes), datasheet reading, code review participation, unit testing

About the role

You will start your firmware career on a team shipping real physical devices, learning embedded engineering from people who have debugged everything you are about to encounter for the first time. Junior firmware engineers here do genuine, valuable work from the first month: peripheral drivers, bug fixes, test automation, and board bring-up support, all with close mentorship and careful code review. You will be expected to ask questions constantly, read large amounts of existing production code, and develop professional habits early: testing on real hardware, writing clearly, and owning your mistakes completely. Engineers who learn fast, stay curious about the hardware beneath their code, and care about craft advance quickly on this team.

What you will achieve

Ship your first production firmware contributions within the first two months, progressing from well-scoped driver fixes to independently owned small features
Build strong embedded fundamentals rapidly: clean C code, careful register manipulation, thoughtful debugging technique, and pull requests that reviewers trust
Contribute meaningfully to team velocity through test automation additions, HIL test coverage, documentation improvements, and lab tooling fixes
Develop genuine hardware awareness by participating in board bring-ups, reading schematics alongside code, and understanding how firmware affects physical behavior
Earn increasing scope and responsibility by demonstrating reliability: hitting commitments consistently, asking for help early, and following through completely

What you will bring

Must-haves

0 to 2 years of professional experience; strong internships, co-ops, or personal projects with microcontrollers and real hardware all count fully
Solid C programming fundamentals: pointers, memory layout, bitwise operations, and demonstrated comfort reading other people's embedded code
Basic microcontroller knowledge: GPIO configuration, timers, interrupt concepts, and UART communication, from coursework or hands-on projects
Ability to read component datasheets and extract the specific information needed to configure a peripheral correctly
Hands-on inclination toward physical hardware: breadboarding experience, basic soldering skills, or clear enthusiasm for working with real devices
Strong communication habits: asking precise questions, writing readable code with useful comments, and giving honest, timely status updates
BS in Electrical Engineering, Computer Engineering, or a closely related field

Nice-to-haves

Personal projects built with STM32, ESP32, Arduino, or similar platforms: designed, debugged, and documented by you
Familiarity with I2C and SPI communication protocols from coursework, projects, or prior internships
Experience with a real-time operating system such as FreeRTOS or bare-metal scheduling from school or hobby work
Contributions to open-source embedded projects or active, helpful participation in embedded community forums
