Senior Dotnet Developer

Job Title : Sr. .Net Developer

Location : Leeds, UK

Work mode : Hybrid - 2-3 days weekly from office

Job type : 6 months fixed term contract

Skills : Strong C# / ASP.NET Core

We at Coforge are looking for an experienced Senior .NET Developer in Leeds, UK.

The project includes work around payment processing, error handling, idempotency, duplicate-payment prevention, retries, recovery and reconciliation with downstream systems.

We’re specifically looking for someone who is still very hands-on technically and can talk clearly about what they have personally designed and built, rather than just describing wider team activity.

The role is very hands-on and will involve helping build a new Azure-hosted payment capability from the ground up. We’re looking for someone who can take ownership of technical work, work closely with architecture, Cloud/DevOps, security and QA, and move quickly from design into build.

The key skills we need are:

• Strong C# / ASP.NET Core
• REST API development
• Entity Framework Core
• SQL Server / Azure SQL
• Dependency Injection / SOLID principles
• Unit and integration testing
• Git / code review / CI/CD
• OAuth 2.0 / OpenID Connect / JWT
• Azure experience, ideally including:
• Docker / containers
• Azure Container Apps or similar
• Azure Key Vault
• Managed Identity
• Application Insights / monitoring
• React experience would be useful
• Payments, transaction processing, reconciliation or financial-services experience would be a strong advantage

Shortlisted candidates may be asked to complete a practical coding exercise as part of the process.
