The Opportunity

Our client, a market-leading engineering solutions group operating across the UK, Europe and the US, is embarking on a major digital transformation – and this is your chance to shape it from the ground up.

They are building a brand-new customer-facing portal designed to revolutionise how clients interact with their suite of products. This is a truly greenfield project — no legacy constraints, no inherited codebases, and complete freedom to architect something exceptional using the latest cloud and web technologies.

This role offers genuine technical autonomy and the chance to influence architecture, tooling, and development standards within a collaborative, forward-thinking engineering function.

The Role

As a Full Stack Developer, you’ll take a leading role in designing, building, and scaling a high-performance web platform that connects complex IoT infrastructure with a clean, intuitive customer interface.

Roughly 80% backend and 20% frontend, this position will see you working end-to-end across:

• Creating intuitive, responsive interfaces using ReactJS and React Native.

• Building secure, scalable integrations with IoT telemetry systems, ensuring real-time data ingestion, storage, and visualisation.

• Implementing modern DevOps practices, CI/CD pipelines, and observability tools to support high availability and performance.

• Collaborating directly with stakeholders to define requirements, design architecture, and guide delivery strategy.

• Mentoring junior engineers and contributing to technical direction and engineering culture.

This is a highly visible, strategic role — where you’ll shape both the technology and how it’s delivered.
