  • Debug and resolve complex system-level issues across hardware and firmware boundaries
  • Establish and enforce best practices around code quality, testing, and documentation
  • Influence the technical roadmap by evaluating and introducing emerging embedded and IoT technologies
  • Communicate complex technical concepts clearly to non-technical stakeholders

What We’re Looking For

Essential Experience

  • 10+ years of experience in embedded firmware development , ideally within IoT or sensor-driven products
  • Deep expertise in low-power embedded systems deployed in production environments
  • Strong experience with LoRa and BLE , including performance tuning and protocol optimisation
  • Proven experience implementing OTA update mechanisms on embedded devices
  • Proficiency in C/C++ on embedded platforms (e.g. ARM Cortex-M)
  • Experience working with RTOS and bare-metal systems (Zephyr exposure is a plus)
  • Strong background in RF systems , including antenna tuning and large-scale deployments
  • Advanced debugging skills using oscilloscopes, spectrum analysers, and JTAG tools

Highly Valued

  • Experience with Cellular CAT M-1 and NB-IoT
  • Familiarity with Nordic platforms and associated SDKs
  • Background in vibration analysis, signal processing, or predictive maintenance systems
  • Proven ability to deliver complex projects end-to-end in resource-constrained environments

Key Attributes

  • First-principles thinker with a strong engineering foundation
  • Comfortable operating in ambiguous, greenfield, or “first-of-its-kind” problem spaces
  • Relentless focus on quality, performance, and continuous improvement
  • Clear communicator who can bridge technical and non-technical teams
