The Role

We’re hiring a Senior Software Developer with 5+ years of hands-on C# / .NET experience. This is a pure individual contributor role with no people management. You’ll spend your days writing code: building backend services and APIs on Azure, owning SQL Server performance, and shipping through automated CI/CD pipelines. You’ll use AI coding tools every day, because that’s how we build.

What You’ll Do

• Design, build and maintain backend services and microservices in C# / .NET
• Build and maintain REST APIs that are well documented, versioned and reliable
• Write and optimize SQL Server queries, stored procedures and schemas, and fix performance issues when they come up
• Develop, deploy and run cloud applications on Microsoft Azure
• Work in Azure DevOps day to day: Git repos, pull requests, pipelines and boards
• Own CI/CD for your services, including automated builds, tests and deployments
• Write unit, integration and regression tests so changes ship with confidence
• Use AI coding tools like GitHub Copilot, Claude Code, Cursor or Codex across your workflow, from writing code to reviewing it and generating tests
• Work in two-week sprints with product, QA and other engineers

Must-Have Skills

• 5+ years of professional backend development with C# and .NET
• Strong SQL Server experience, including query writing and performance tuning
• Hands-on experience building and deploying applications on Microsoft Azure
• Proven experience building and maintaining REST APIs
• Daily working experience with Azure DevOps (Git, pipelines, development workflows)
• Experience setting up and maintaining CI/CD pipelines
• Solid automated testing habits across unit, integration and regression tests
• Experience building backend microservices
• Regular, hands-on use of AI coding tools (Copilot, Claude Code, Cursor, Codex or similar). You use them daily and know where they help and where they don’t.
• Comfortable working in Agile / Scrum sprints

Nice to Have

• Experience with .NET 10
• Swagger / OpenAPI for API documentation
• Background in FinTech, financial services or trading software
• Experience using AI for code reviews and test generation
• Desktop application development experience
• Datadog or similar monitoring and observability tools

• Competitive salary, industry-benchmarked and USD-pegged
• AI-first engineering culture where AI tools are part of the stack, not an afterthought
