• Create conceptual, logical and physical designs, and document them with use cases and diagrams.

Engineering and delivery

• Build and maintain enterprise applications in C# and .NET 8+, across back end, APIs and user interfaces.
• Lead modernisation onto .NET 8, 9 and 10.
• Own application performance, scalability and reliability, including monitoring, logging and observability.
• Oversee SQL Server design, optimisation and high-volume data processing.
• Drive CI/CD, DevOps practices and automated build, test and deployment.

Leadership and quality

• Mentor and develop Software Engineers I and II, and help build a high-performing team.
• Work with architects, product owners and business stakeholders within Agile delivery and SDLC governance.
• Identify technical risks early and drive mitigation.

• Git or TFS, and experience on Agile and DevOps projects.
• Cloud services experience on Azure or AWS.
• A good understanding of networking and security principles.
• Proven technical leadership: mentoring developers and leading code reviews.
• Retail experience.
• Practical use of AI-assisted development tools, such as GitHub Copilot, Claude or similar, to improve productivity and code quality.
• Clear communication and strong stakeholder engagement, turning business needs into technical solutions.

Advantageous

• Exposure to .NET 9 and 10.
• Domain-Driven Design (DDD) and CQRS.
• Event-driven architecture with Azure Service Bus, Kafka, RabbitMQ or similar.
