Embedded Firmware Engineer
Neurable Mid-Level (2-4 Years) | On-Site | Full-Time
ABOUT NEURABLE
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 β and that's where you come in.
THE ROLE
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 β and you want that hardware to do something genuinely new β 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 β 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 β 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
WHAT WE'RE LOOKING FORRequired
- 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
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
WHAT WE OFFER
- Competitive base salary commensurate with experience
- Equity participation in a high-growth neurotechnology company
- Comprehensive health, dental, and vision benefits
- A collaborative, mission-driven team working on genuinely novel technology
- Direct access to leadership and meaningful impact from day one
- The chance to see your firmware running on hardware that's redefining how people interact with computers
