You will collaborate closely with front-end and app developers to deliver high-quality APIs. Your code should be reliable, readable, and clean—prioritizing maintainability over overly complex solutions.

• Gather and assess technical and design requirements.
• Build scalable and dependable code.

Requirements & Skills

• Proven experience as a Backend Developer.
• In-depth knowledge of backend and server technologies.
• Hands-on experience with server-side programming languages such as C#, Java, or PHP (preference for .NET frameworks).
• Working knowledge of RESTful applications.
• Experience with Entity Framework Core.
• Familiarity with DTO patterns, dependency injection, and Swagger/OpenAPI.
• Hands-on experience with database technologies such as PostgreSQL and NoSQL (e.g., MongoDB).
• Knowledge of manipulating file systems on servers and client-side devices.
• Experience with testing (integration and unit tests).
• Working understanding of HTML, CSS, and JavaScript (desirable but not required).
• Excellent analytical and time management skills.
• Strong problem-solving abilities.
• BSc in Computer Science or equivalent experience.
• Experience with OAuth2/OIDC (desirable but not required).
