About the role

Key responsibilities & impact

Develop and improve EEG and biosensing wearable firmware
Own firmware releases end to end, including scope, code freeze, QA and regression cycles, release notes, and inter-team communications
Maintain and extend shipping STM32 firmware while bringing up new platforms
Design and debug BLE protocols, throughput, latency, connection reliability, and field connection issues
Integrate Bluetooth audio codecs and I2S/PDM microphone and speaker paths alongside continuous sensor streaming
Implement biosignal acquisition for EEG, PPG, and fNIRS front ends, including sensor presets, on-device filtering, stream formats, and telemetry
Configure PMICs, fuel gauging, low-power and sleep modes, and battery-life improvements
Perform field debugging across firmware, hardware, and app layers using logs, RTT capture, crash reporting, and product analytics
Develop manufacturing and factory-test firmware, flashing flows, test-time reductions, and internal tooling
Bring up new hardware, peripherals, PMICs, batteries, and sensors using datasheets, schematics, and measurements
Collaborate with mobile app, cloud, QA, research, customer care, and contract manufacturing teams across time zones
Write architecture notes, protocol specifications, release documentation, and onboarding material

Requirements

What you’ll need

5+ years of embedded firmware development in C and scripting in Python
Experience with RTOS (ThreadX, Zephyr, etc.) or bringing up an unfamiliar vendor SDK
Experience with PCB communication protocols: I2C, SPI, UART, JTAG/SWD, etc.
STM32 experience is an asset
Experience owning firmware releases, including versioning, branching, and release criteria
Ability to drive firmware projects independently
Ability to design firmware architecture and create scalable firmware protocols
Experience with secure bootloaders and firmware update mechanisms; MCUboot or comparable, image signing, rollback protection, and encryption
Experience with BLE, including protocol design and debugging real-world connection problems
Ability to read schematics and component datasheets, bring up an eval board, take measurements, and provide feedback on circuit design
Comfortable with J-Link / ST-Link, SWD, SWO/RTT, logic analyzers, and oscilloscopes
Willingness to learn and practice meditation
Experience with consumer audio and Bluetooth audio stacks is a bonus
Experience with biosignals on wearables or medical-device firmware is a bonus
Familiarity with analog and digital signal processing and sensor front ends is a bonus
Low-power design, PMICs, and fuel gauging experience is a bonus
Familiarity with software development life cycle, agile methodology, CI/CD, and hardware-in-the-loop testing for embedded is a bonus
Experience working with contract manufacturers or offshore engineering partners and factory test systems is a bonus
