Want real influence across every discipline of a connected hardware product, rather than staying boxed into one layer of the stack?

We're working with a fast-growing connected-device business building an advanced IoT hardware product with real system architecture and connectivity complexity. They need a Senior System Engineer to shape requirements across system, hardware, embedded, ATE, software and integration, contribute to design decisions in each discipline, and lead proof-of-concept and field testing.

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 environment
• 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
• Some backend or serverless systems knowledge
• Exposure to cloud infrastructure for IoT products

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