Stelvio Group is working with a high-growth technology business operating at the intersection of embedded systems, IoT, and transportation technology . They are looking to appoint a Principal Embedded Systems Engineer to play a critical role in scaling next-generation sensor platforms used in demanding, real-world environments.
This is a senior, hands-on role with genuine technical influence. The position can evolve into a leadership path or remain deeply technical, depending on the individual.
What You’ll Be Doing
- Architect, design, and implement firmware for next-generation IoT sensor platforms
- Lead development of ultra-low-power strategies for battery-powered, remote devices
- Own and optimise wireless communication stacks , including LoRa and BLE
- Design and refine signal filtering and processing solutions for noisy, industrial environments
- Define firmware architecture and system-level requirements in collaboration with hardware and product teams
- 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
