Responsibilities
- Design, implement, and maintain embedded firmware and low-level software components for resource-constrained hardware platforms
- Develop and debug hardware abstraction layers, device drivers, and board support packages for custom silicon and peripherals
- Integrate and configure real-time operating systems (RTOS) to meet latency, power, and memory requirements
- Write automated tests including unit, integration, and hardware-in-the-loop tests to validate firmware behavior across expected and error conditions
- Instrument firmware with logging, metrics, and alerting to support observability and production reliability
- Collaborate with hardware engineers, silicon teams, and product partners to define firmware interfaces and resolve cross-disciplinary dependencies
- Participate in code reviews to improve firmware quality, identify common embedded software defects, and share knowledge with peers
- Analyze and optimize firmware for power consumption, memory footprint, and real-time execution performance
- Own embedded software components end-to-end, including responding to production issues and maintaining code health through deprecation of obsolete implementations
- Produce clear technical documentation for firmware interfaces, bring-up procedures, and system behaviors to support current and future contributors
Minimum Qualifications

- 5+ years of experience developing embedded firmware or low-level software in C or C++
- Experience with real-time operating systems (RTOS), bare-metal programming, or embedded Linux environments
- Experience developing or debugging device drivers, hardware abstraction layers, or board support packages for microcontrollers or SoCs
- Experience writing automated tests and using debugging tools such as JTAG, oscilloscopes, logic analyzers, or serial debuggers to isolate and resolve firmware defects
- Experience analyzing and optimizing embedded software for power, latency, or memory constraints
Preferred Qualifications
- Experience with sensor fusion, signal conditioning, or ADC/DAC interfacing
- Experience with optical sensor integration and signal processing
- Experience with communication protocols commonly used in embedded systems such as SPI, I2C, UART, USB, or Bluetooth Low Energy
- Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
- Experience with power optimization for battery-constrained wearable or portable devices
- Experience developing firmware for low power analog sensors
- Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
- Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
- Familiarity with continuous integration workflows adapted for embedded targets, including cross-compilation and hardware-in-the-loop testing pipelines
- Experience with embedded software development for consumer electronics, wearables, or IoT devices
