What You'll Bring

- Experience in system engineering of multidisciplinary hardware products
- Background working with communication products, embedded systems, hardware or RF
- A natural problem-solver who works well both independently and in a team




- Quick to get to grips with new, complex IoT concepts and weigh up alternative approaches
- Comfortable operating on projects that demand real technical depth across disciplines

Also Valued

- Comfortable in a Linux setting
- Experience with Atlassian tools and/or Azure DevOps
- Curiosity about applying agentic AI to discovery and innovation work
- Coding ability in C, C#, Java or Python
- Familiarity with RF technologies such as BLE, WiFi, LTE-M or LoRa

If you want genuine cross-disciplinary ownership on a technically rich product, this is a role where that scope is real.
