Work in a modern TypeScript-based stack using object-oriented principles and design patterns
Collaborate closely with architects, product managers, and fellow engineers to turn product requirements into robust, maintainable code
Write clean, testable, and reusable components with a strong focus on quality (unit tests, TDD mindset)
Contribute to internal tools that improve engineering quality and developer experience

Your profile

You have strong software engineering fundamentals and enjoy solving algorithmic or mathematical problems
You are fluent in OOP concepts and design patterns (e.g., Factory, Strategy, etc.)
You understand and follow SOLID principles
You have strong proficiency in TypeScript, with familiarity in other object-oriented languages (e.g., C#, Java) as a nice-to-have
2+ years of professional experience in designing and delivering production-ready applications
Good communication skills and a collaborative mindset
