At Materialise Medical, we develop advanced 3D medical planning tools that empower clinicians and researchers to create patient‑specific treatments. We are now looking for a front‑end software engineer who is passionate about well‑structured, object‑oriented code and clean architecture.

• 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

Nice to have

• Experience with 3D rendering, computational geometry, or scientific visualization
