.NET Developer

Over the past 30 years, we’ve grown from humble beginnings with a single computer into a diversified, global, technology-enabled lottery and prize draw company (ASX: JIN). Today, Jumbo operates across Australia, the UK, Canada and the US, bringing together technology, creativity and purpose to create premium digital experiences people love.

Based in Galgate, Star Vale is dedicated to strengthening the fundraising power of charities, not‑for‑profits, and hospices across the UK. We combine specialist lottery management with a genuine commitment to helping organisations maximise their impact, so more communities receive the support they deserve.

We’re looking for a .NET Web Developer to join us in this hands‑on build‑and‑migrate role. You will be rewriting existing PHP websites in .NET, integrating them with our business systems, and helping shape how we structure our shared architecture going forward. Working closely with cross‑functional teams, you will support day‑to‑day business needs, solve complex technical challenges, and contribute to high‑quality engineering practices through code reviews, documentation, and collaborative solution design.

Your daily work will centre on maintaining, modernising, and progressively transforming our legacy .NET systems while supporting the smooth running of core business operations across Star Vale. You can expect to:

• Design and build ASP.NET Core websites targeting modern .NET versions (including .NET 10)
• Migrate Laravel and Code Igniter sites to the .NET platform while preserving functionality, SEO, and data integrity
• Work with Umbraco CMS — extending existing implementations or building new sites where appropriate
• Integrate websites with core .NET business systems and SQL Server databases
• Write and maintain EF Core data access code, including migrating data from MySQL to SQL Server
• Document business logic and edge cases from existing PHP sites before decommissioning
• Contribute to shared architecture decisions, internal libraries, and coding standards
• Write clean, tested, maintainable code and participate in code reviews

• Solid commercial experience with C# and ASP.NET Core (or strong ASP.NET MVC experience with a clear path to Core)
• Experience with Entity Framework Core (or EF) and relational databases (SQL Server)
• Comfortable working with front‑end fundamentals (HTML, CSS, JavaScript) alongside server‑rendered .NET views or Razor Pages
• Experience migrating or integrating systems between different platforms or frameworks
• Ability to read and understand PHP (Laravel and/or Code Igniter) well enough to translate existing functionality into .NET — you won't be writing new PHP, but you'll need to understand what’s there
• Good understanding of web fundamentals: routing, authentication, forms, SEO basics (URL structure, redirects)

• Migration Mindset:
  Confidence to evaluate legacy code, challenge outdated practices, and guide non‑technical stakeholders through modernized technical solutions.
• Problem Solver:
  Highly resourceful with strong initiative, able to own projects independently from requirements‑gathering to deployment.
• Communication:
  Excellent people skills to liaise effectively between technical teams, external auditors, and cross‑departmental stakeholders.

• Experience with Umbraco CMS
• Experience with Blazor
• Familiarity with Azure or other cloud hosting for .NET applications
• Experience leading or contributing to a platform migration or legacy system modernization
• Understanding of REST API design, for connecting websites to internal business systems
• Ability to work within agile environments, including Kanban and Sprints.
