- Make pragmatic technical decisions and actively contribute to the evolution of the architecture.
- Work with existing code and gradually improve or modernize solutions where it brings real value.
- Use AI tools throughout the development process, from requirements analysis to implementation, while critically reviewing and validating the results.
- Work closely with AI Engineers to integrate AI-powered functionality with backend services.
- Own features end-to-end - from clarifying requirements through implementation and testing to deployment and monitoring.
- Collaborate with Product, QA, DevOps and other Engineers.
- Share knowledge, participate in code reviews and contribute to improving the way the team works.
Requirements:
- 3+ years of experience developing backend applications with C#/.NET.
- Strong knowledge of C#/.NET and experience independently implementing production features.
