• Collaborate with hardware, software, and neuroscience teams to ensure seamless system integration.
• Debug, optimize, and ensure high code quality through testing (unit tests, system tests) and detailed documentation.
• Troubleshoot complex hardware and firmware issues using tools like oscilloscopes, logic analyzers, and debugging software to optimize performance and reliability.
• Stay current with advancements in embedded systems, biofeedback technology, and neurofeedback research to drive product innovation.

Qualifications:

• At least 3+ years in embedded firmware development (preferably in healthcare, neurofeedback, or wearable devices).
• Bachelor's/Master's in Electrical, Computer, Biomedical Engineering, or a related field.
• Proficiency in C/C++, embedded firmware architecture, and microcontrollers (STM32, nRF52, ESP32).
• Experience with RTOS, DSP for biomedical signals (EEG), and low-power firmware for battery devices.
• Strong debugging skills (oscilloscopes, logic analyzers) and communication protocol development (Bluetooth LE, Wi-Fi, SPI, I2C, UART).
• Strong problem-solving, documentation, and communication skills in English.

Preferred Skills (Nice-to-Have):

• Knowledge of EEG/PPG signal processing, neurofeedback, and regulatory standards (IEC 62304, FDA, CE).
• Experience with ML in embedded systems, Python/MATLAB for signal analysis, and hardware design.
• Leadership/mentorship experience in technical teams.

What We Offer

• Full-time position with a competitive salary.
• Start ASAP with benefits per regulations.
• Work Environment: Dynamic, innovative, and collaborative.
• Opportunities: Advance neurofeedback tech, collaborate with experts, and drive innovation.

Key Contributions
