  • Test on real hardware and in simulation mode, and document the work
  • Use Git with clear commits and code reviews

Qualifications:

  • 0–3 years of embedded firmware experience (strong project or internship work counts)
  • Proficiency in C/C++ for embedded systems
  • Hands-on experience with Teensy 4.x (or similar ARM Cortex-M boards) and FreeRTOS
  • Solid grasp of electronics fundamentals, including reading schematics, using a multimeter, oscilloscope, or logic analyzer, and working with GPIO, ADC, PWM, and timers
  • Experience with Git
  • Reliable, present, and curious; comfortable working with hardware on-site and accepting an essential role

Preferred Qualifications:

  • Experience with medical, biomedical, or safety-critical devices
  • Familiarity with signal processing or sensor data acquisition
  • Basic Python or C# for testing and tooling
  • Comfort with unit testing and simulation

Education: Bachelor’s degree in electrical engineering, computer engineering, or a related field

Compensation offered will be determined by factors such as location, level, job-related knowledge, skills, and experience. Range is $70-$80 per hour.
