• Collaborate with BAs, testers, solution architects, and product owners
• Document APIs and technical decisions to support maintainability

What you'll need to succeed

• Strong commercial experience with .NET Core / C# (.NET 5/6; .NET 8/10 exposure highly regarded)
• Hands-on experience building APIs on Microsoft Azure (App Services, Functions, Azure SQL, etc.)
• Solid Entity Framework Core experience
• Advanced SQL Server / T-SQL, including stored procedure development and performance tuning
• Proven experience integrating with or modernising legacy systems (10–20+ years old)
