The challenge

Design, build and ship full stack applications on a microservices based architecture, with REST APIs as the integration backbone and a DXP/CMS layer (Optimizely, Umbraco or equivalent) powering the content experience.

• Design scalable system architectures and microservices based solutions with cross functional teams
• Optimize SQL and NoSQL databases for performance and scalability
• Streamline delivery with GitHub workflows and actions
• Guide technical implementation, drive architectural decisions and mentor more junior developers

✅ Requirements

• 3+ years as a C# .NET developer (.NET Framework and .NET Core)
• Hands on experience with React and Next.js (mandatory)
• Hands on experience with a DXP/CMS platform: Optimizely, Umbraco or equivalent
• Solid REST API knowledge and proven experience designing scalable architectures and microservices
• Proficiency in SQL and NoSQL databases, including optimization
• Familiarity with DevOps tooling, specifically GitHub workflows and actions
• Technical leadership: proven ability to guide teams, make architectural decisions and communicate clearly
