Embedded Firmware Engineer

We're looking for an Embedded Firmware Engineer who thrives at the boundary between hardware and software. You'll write the C/C++ firmware that runs on our STM32-based wearables, debug tricky hardware-software interactions on the bench, and work closely with our hardware and research engineering teams to turn novel signal-processing ideas into reliable, real-time, low-power code on real devices.

You'll have ownership over meaningful chunks of the firmware stack from day one, with plenty of room to grow into deeper specialization (low-power design, BLE, signal processing) or broader ownership across the firmware platform. If you like seeing your code run on hardware you can hold in your hand - and you want that hardware to do something genuinely new - this is a great seat.

WHAT YOU'LL DOFirmware Development

• Design, write, and maintain C/C++ firmware for STM32 (ARM Cortex-M) microcontrollers powering Neurable's wearable EEG devices
• Build and refine RTOS-based applications using FreeRTOS, Zephyr, or similar - including thread-safe task design, synchronization, and inter-task communication
• Implement and optimize peripheral drivers and integrations across I2C, SPI, UART, and USB
• Partner with Research Engineers to translate Python-based signal-processing prototypes into efficient, real-time C/C++ implementations that fit within MCU constraints

Hardware/Firmware Integration & Debug

• Bring up new hardware revisions alongside the hardware team, validating firmware against schematics and bench measurements
• Debug complex hardware-software interactions using oscilloscopes, logic analyzers, and multimeters
• Drive root-cause analysis on tricky bugs - reproduce, document, and fix issues that span the firmware/hardware boundary
• Contribute to board bring-up tasks including basic soldering and minor rework as needed

Reliability & Collaboration

• Participate actively in code and design reviews, bringing a test-first mindset and an eye for reliability
• Work in Git with clean branching, focused pull requests, and clear commit history
• Document firmware behavior, debug findings, and reproduction steps so your teammates can build on your work
• Engage with AI-assisted development workflows to move faster without sacrificing quality

Do you have experience in Version control?, * Bachelor's degree in Electrical Engineering, Computer Engineering, Biomedical Engineering, Computer Science, or a related field

• 2+ years of full-time experience in embedded systems or firmware development
• Strong proficiency in C/C++ for resource-constrained environments, with hands-on experience on STM32 or comparable ARM Cortex-M microcontrollers
• Practical understanding of RTOS primitives (tasks, semaphores, mutexes, queues) and thread-safe programming; experience with FreeRTOS, Zephyr, or similar real-time operating systems
• Hands-on experience with I2C, SPI, UART, and USB
• Ability to read and debug complex electronic schematics and use standard lab equipment (oscilloscopes, logic analyzers, multimeters) to troubleshoot hardware/software interactions
• Proficiency with Git (branching, merging, pull requests)
• Strong root-cause analysis skills and the ability to clearly document reproduction steps for complex bugs
• Ability to communicate technical details clearly across hardware, firmware, and research teams

Nice to Have

• Understanding of ADC/DAC operations and the challenges of working with high-sensitivity analog signals
• Experience translating Python-based signal-processing algorithms into optimized real-time C/C++ for embedded environments
• Experience using DMA for efficient data transfer
• Experience implementing low-power modes (Sleep/Stop/Standby) for battery-operated wearables
• Working knowledge of BLE (Bluetooth Low Energy) stacks and power profiling
• Proficiency with common hand tools and basic soldering for board bring-up or minor rework
• Background or interest in biosignals, neurotechnology, or wearable medical devices

How We Work

• A test-first mindset and active participation in code/design reviews to maintain high reliability
• Demonstrated ability to ramp up on unfamiliar systems quickly
• Willingness to engage with AI-assisted workflows as part of how we build

Neurable's pioneering software and hardware technology enables electroencephalography (EEG) devices to be utilized outside of controlled lab environments on a large scale. This is an opportunity to join a high-impact company, collaborate with a world-class team, and work on technology that will redefine human-computer interaction. The firmware running on our wearables is what makes high-quality EEG outside the lab possible - and that's where you come in.
