• Take full ownership of the development lifecycle, from architecture and implementation through to deployment, monitoring, and maintenance.
• Design and implement secure, performant, and well-optimized RESTful services.
• Build and maintain cloud-native solutions, preferably on Azure.
• Work with ORMs (e.g. EF Core), SQL Server, and/or NoSQL databases to manage and optimize data persistence.
• Implement and maintain CI/CD pipelines to support continuous integration, automated testing, and deployment.
• Write clean, maintainable, and testable code following best practices in OOP, SOLID principles, and domain-driven design.
• Participate in Agile ceremonies including sprint planning, retrospectives, and daily stand-ups.
• Contribute to architectural decisions and code reviews, and promote shared engineering standards across backend and frontend teams.

What you have

• 7+ years of professional experience as a Full Stack Developer.
• Strong proficiency in C#, .NET 8+, ASP.NET Core, and Angular.
• Solid understanding of software architecture, design patterns, and microservice principles.
• Proven experience building and maintaining RESTful APIs and integrating them with web frontends.
• Experience with ORMs (e.g. Entity Framework Core), LINQ, and database optimization for relational (SQL Server, PostgreSQL) and/or NoSQL (Cosmos DB, MongoDB) data models.
• Exposure to Domain-Driven Design (DDD), CQRS, or Event-Driven Architecture.
• Familiarity with cloud infrastructure, preferably Microsoft Azure.
• Solid understanding of frontend-backend integration, authentication flows, and API design.
• Experience with CI/CD tools such as Azure DevOps, GitHub Actions, Jenkins, or IaC.
• A strong commitment to high-quality user experiences, even in backend-driven features.
• A track record of owning features and systems end-to-end throughout the full development lifecycle.
• Comfortable working in product-driven, fast-paced environments with cross-functional teams.
• Direct experience directing AI agent code generation workstreams (Claude Code, Cursor Agent, or GitHub Copilot Workspace) in a production delivery context.

Education

A bachelor's degree in Computer Science, Software Engineering, or a related field would be of great value, but if you're passionate and your experience backs up your abilities, talent outweighs degree every time.
