About the role

  • Lead the refactoring and restructuring of an existing embedded firmware codebase into a modular, maintainable C-based architecture.
  • Develop and maintain sensor processing logic, including filtering and normalization of noisy data.
  • Optimize firmware performance and resource usage to support evolving hardware platforms.
  • Design and implement robust connectivity logic to handle unstable networks, offline scenarios, and reconnects.
  • Build local data caching and synchronization mechanisms for reliable data delivery.
  • Implement and maintain OTA firmware update mechanisms for deployed devices.
  • Collaborate closely with hardware engineers during board bring-up and platform changes.
  • Support testing and validation across firmware and hardware lifecycle phases.

Requirements

  • 7+ years of professional experience in embedded firmware development.
  • Strong experience writing production-level C (and working knowledge of C++).
  • Hands-on experience with ARM-based, Linux embedded systems.
  • Proven background working on IoT devices and sensor-based systems.
  • Experience maintaining and improving legacy firmware systems.
  • Comfortable operating independently on system-level problems.
  • Must Have Experience
  • Advanced proficiency in C and understanding of C++
  • Strong knowledge of memory management, pointers, concurrency, and resource constraints.
  • Experience with Embedded Linux (user-space applications, BSP familiarity).
  • Hands-on experience with AWS IoT Core, including MQTT and device connectivity.
  • Experience designing offline-first systems (local caching, store-and-forward, reconnect logic).
  • Familiarity with OTA firmware updates (custom solutions or tools like Mender / Yocto).
  • Experience working with Wi-Fi–enabled embedded devices.
  • Experience working with Bluetooth or Bluetooth Mesh
  • Knowledge of industrial communication protocols (I²C, SPI, UART)
  • Experience with sensor data filtering, debouncing, or signal normalization
  • Desired - Not Required
  • Familiarity with MQTT-based mesh or distributed systems
  • Exposure to AWS Greengrass or containerization on embedded devices
  • Experience supporting hardware cost-down initiatives or porting firmware to constrained platforms (e.g. ESP32, STM32)
