The Role

Write clean, maintainable, well-tested code and contribute to evolving engineering standards and best practices

Troubleshoot and resolve production issues across the fullstack from database to UI

Bachelor’s degree in Computer Science, Computer Engineering, or related field with 5+ years of fullstack development experience

Proven experience with .NET Framework and modern .NET (ASP.NET Core, ASP.NET MVC)

Strong hands-on experience with MSSQL (T-SQL, query optimization, indexing, stored procedures), including schema design, query optimization, and performance tuning

Solid experience developoing APIs (REST/Web APIs); experience with GraphQL, ideally using Hot Chocolate is an asset

Proficiency with React.js, JavaScript/TypeScript and modern frontend development practices

Experience working in multi-tenant or enterprise software environments is an asset

Experience with cloud platforms (AWS, Azure, or GCP)
