Embedded Firmware Developer

Fresh Consulting is recruiting for an unnamed client building a noninvasive cardiac diagnostic platform. The Embedded Firmware Developer will develop, maintain, debug, test, and document device firmware and coordinate its operation with desktop software.

What you'll do:

• Develop, maintain, and debug firmware for a Teensy 4.x-based system
• Build and manage real-time tasks using FreeRTOS
• Control and monitor hardware such as valves, sensors, and actuators
• Implement communication between the firmware and host software (serial/UART, SPI, I2C)
• Add logging and live debugging so the firmware state can be inspected in real time
• Test on real hardware and in simulation mode, and document the work
• Use Git with clear commits and code reviews

What they're looking for:

• 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
• Bachelor's degree in electrical engineering, computer engineering, or a related field
• 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

Benefits:

• Employee benefits at 100%, including Medical, PTO, Holiday Pay, and a 401K Plan.
