Offre d'emploi Senior Software Developer .Net & Blazor

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.

• Design, develop and maintain core software applications used in automation and production environments
• Lead hands-on development in C#/.NET, contributing to system migration and platform evolution
• Build and enhance operator-facing applications, dashboards and visualisation tools displaying real-time system data
• Own application logic, workflows and behaviour within production systems
• Contribute to overall software architecture, technical standards and development best practices
• Implement and maintain version control and CI/CD pipelines using GitHub
• Ensure applications are reliable, maintainable and resilient, with a strong emphasis on fault handling and diagnostics
• Collaborate with controls, robotics and mechanical engineers to ensure seamless integration with physical systems
• Support testing, commissioning and deployment of software releases
• Mentor junior developers and contribute to technical decision-making within the team

• Strong commercial experience with C# and .NET
• Experience building user interfaces and application logic using Blazor or similar frameworks
• Background in Python, ideally within Django environments (particularly for legacy systems or migrations)
• Hands-on experience with GitHub, including branching strategies, pull requests and CI/CD workflows
• Strong understanding of clean code principles, maintainability and scalable software design

• Experience developing software for industrial, manufacturing, automation, logistics or IoT environments
• Understanding of how software interacts with PLC-controlled or machine-driven systems (no PLC programming required)
• Comfortable working in environments where uptime, reliability and performance are critical

• 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

• 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
• A collaborative, multidisciplinary environment with exposure to cutting-edge automation technologies
• Influence over technical direction, standards and best practices

This role is:

• A hands-on senior software development position
• Focused on building robust, scalable applications
• Product and platform oriented
• Embedded within a real-world automation environment

This role is not:

• A PLC programming position
• A controls engineering or systems integration-only role
• A pure web or SaaS-focused development job
