Senior Software Developer - Industrial Automation Environment

We are seeking a Senior Software Developer to play a key role in designing, building and maintaining core software applications that support advanced automated materials handling, warehouse automation and robotics-led production environments.

This is a software-led position, focused on developing production-grade applications, platforms and user interfaces. While the software operates within an industrial setting, the primary responsibility is software engineering - not hardware configuration or PLC programming.

You will join a team responsible for modernising an existing technology stack, contributing to the transition from Python/Django to C#/.NET and Blazor. This role offers ownership across application design, architecture, and long-term maintainability, alongside close collaboration with engineering teams to ensure software aligns with real-world systems.

Experience designing and maintaining long-running, production-grade systems

Ability to build fault-tolerant applications interacting with external systems and data sources

Strong debugging, troubleshooting and problem-solving capability

What This Role Offers

The opportunity to work on real-world, high-impact systems combining software, robotics and automation

Ownership of critical applications that directly influence operational performance

Involvement in a large-scale technology modernisation programme
