Outside IR35 Contract Opportunity — Lead Embedded Software Engineer

Location: Central Birmingham

Sector: Next-Generation Consumer Electronics

Contract: Outside IR35 | Competitive Day Rate

Join a cutting-edge product development team shaping the next generation of smart home technology. This is your chance to work with a forward-thinking company that’s redefining how people interact with connected devices — from prototype to production. This is a 100% hands on role (you will not be managing) but will contribute to the strategy.

You’ll be joining a fast-paced, innovation-driven environment where your expertise in Embedded C/C++ and STM32 microcontrollers will help bring intelligent, connected home products to life.

What You’ll Be Doing

Enhancing and extending functionality of existing drivers
Integrating low-level embedded systems with cloud technologies and mobile applications
Taking ownership across the full product lifecycle, from prototype through to production

Key Skills & Experience

Strong background in Embedded Linux and C++ development
Hands-on experience with BLE and Wi-Fi connectivity
Knowledge of OTA firmware updates
(Bonus) Experience with telemetry data syncing
Familiarity with or interest in AI Cursor / Codex or similar AI-assisted development tools
Exposure to cloud-based integrations

Why Join?

Work outside IR35 on a high-impact project in consumer electronics
Collaborate with a passionate, cross-functional team pushing boundaries in home innovation
Gain experience with the latest AI-assisted development tools and cloud-connected ecosystems

If you’re an embedded engineer who thrives on innovation and wants to make an impact in the world of connected products — this is the contract for you. This could suit either a high performing Embedded Software Engineer with just a few years experience in the above but strong academic background and a willingness to embrace new technologies and work in a fast paced environment.

It could also suit a very experienced engineer providing you are open to embracing new technologies, ways of working and contribute in a fast paced environment. The OTA experience is particularly of interest.

Apply now to be part of something truly next-generation.
