Senior/Staff Firmware Engineer

Company Overview:

BrightAI is a high-growth Physical AI company transforming how businesses interact with the physical world through intelligent automation. Our platform processes visual, spatial, and temporal data from billions of real-world events—captured through edge devices, mobile sensors, and large-scale cloud infrastructure—to deliver intelligent, real-time decisions.

Responsibilities

• Design, implement, and maintain embedded firmware with a strong emphasis on ultra-low power consumption.

• Develop drivers and low-level firmware for microcontrollers (MCUs), sensors, and wireless modules (e.g., BLE, Zigbee, LoRa).

• Collaborate with hardware engineers to define power budgets and validate low-power designs.

• Implement and test power management techniques such as sleep modes, clock gating, and dynamic voltage scaling.

• Perform power profiling and debugging using tools such as oscilloscopes, logic analyzers, energy analyzers and current probes.

• Optimize code size and execution efficiency in resource-constrained environments.

• Ability to work in a no-OS or lightweight RTOS environment

• Participate in design reviews, code reviews, and contribute to technical documentation.

• Ensure compliance with industry standards and best practices for embedded development.

• Lead the integration of embedded communication protocols like I2C, SPI, and UART, facilitating robust data exchange across various embedded system components.

Skills and Expertise:

• BS/MS degree in Computer Science, Electrical Engineering, Computer Engineering, or a related field.

• 7+ years of experience in embedded software development, with a strong emphasis on low power design.

• Proficiency in C/C++ for embedded systems.

• Hands-on experience with low-power microcontrollers (e.g., ARM Cortex-M series, nRF52, Ambiq, MSP430).

• Familiarity with RTOS concepts and experience with lightweight operating systems (e.g., FreeRTOS or Zephyr).

• Deep understanding of hardware/software interaction and power management techniques.

• Deep familiarity with source control (Git) and development workflows.

Bonus Criteria:

• Experience with wireless communication protocols (BLE, Zigbee, LoRa, etc.).

• Knowledge of PCB schematics and the ability to work closely with hardware engineers.

• Familiarity with version control systems (e.g., Git).

• Experience with scripting languages (Python, Bash) for test automation.

• Prior work on battery-operated or energy-harvesting devices.

• Advanced skills in designing optimized solutions using C for embedded systems with stringent resource constraints.

• Strong background in math-based programming, with the ability to apply linear algebra for complex tasks like digital signal processing and machine learning.

• Experience in developing AI/ML solutions, with hands-on expertise in frameworks such as Edge Impulse, OpenCV and PyTorch for embedded applications.

• Deep experience in system architectures, including event-driven and modular design approaches, as well as abstracting hardware layers (HAL, sensor fusion, application layers).

• Proven experience in developing, maintaining, and scaling CI/CD pipelines, particularly with tools like GitHub Actions, to ensure high-quality, automated build and release processes.
