- Extend and maintain unit tests, integration tests, and hardware-in-the-loop tests
- Design and develop embedded firmware for IoT devices
- Integrate hardware with IoT communication protocols and cloud services
- Optimize power consumption and data transmission for network efficiency
- Collaborate with hardware, software, and network teams to ensure interoperability
- Maintain and update firmware for security and performance improvements
- Document design specifications, test results, and deployment procedures
- Feature delivery and quality
- Requirement refinement to release implementation, code reviews, verification, and documentation
- Debug complex issues across firmware, CAN, SPI, I2C, UART, and power-management domains
- Support the product roadmap for LTE CAT 1, LTE-M, Cat-1 Bis, CAT 4, NB-IoT
- Support the product roadmap for BLE, RFCOMM, WiFi
- Support the roadmap for location technologies like GNSS, WiFiSCAN
- Simulation and tools
- Build and maintain simulators, emulators, and test harnesses in C#, Python, and C to accelerate development
- Create protocol simulators and hardware abstraction layers for off-target testing
- Documentation and process
- Produce clear programming documentation, API references, and design specs
- Contribute to configuration management, release notes, and firmware change control
- Collaborate with systems engineering on requirements, traceability, and verification evidence
Additional responsibilities as needed to support the team and company goals.
