- Design and implement scalable data access strategies utilizing relational (SQL Server) and NoSQL databases, including MongoDB.
- Implement and maintain enterprise search solutions using technologies such as Apache Solr.
- Write clean, testable, and maintainable code with proper documentation.
- Take full ownership of testing your own code—unit, integration, and performance testing—as part of a Shift Left / No QA team setup.
- Collaborate with product managers and other teams to understand requirements and deliver customer-focused features.
- Use AI development tools (required)—including GitHub Copilot, Claude, or similar—to assist with code generation, refactoring, documentation, and development speed.
What you should bring:
- 5+ years of experience in enterprise or SaaS software development.
- Strong hands-on experience with: C#,.NET Core, Web API, and experience with migrating applications to.NET Core 8.
- Entity Framework (EF Core or EF6) Mongo DB, SOLR SQL Server – writing queries, stored procedures, indexing, and performance tuning.
- Solid understanding of object-oriented programming, design patterns, and enterprise architecture.
- Experience with DDD, CQRS, and clean layering of business logic and data access.

- Comfortable with Git and working in a modern development environment (CI/CD, Agile).
- Strong debugging and troubleshooting skills.
- Excellent communication skills (written and verbal) in English.
- Experience working across multiple teams or squads.
- Experience with modern frontend frameworks, specifically Angular (version 20 or later is highly desirable).
- Required: Active daily use of AI development tools like GitHub Copilot, Claude, or similar in your workflow.
Bonus points:
- Real-world experience building AI-powered features (e.g., smart forms, intelligent search, NLP features).
