You’ll be involved in modernizing foundational systems and administrative tooling, while collaborating closely with multiple product teams during their migration journey.

- Design, build, and maintain backend services using C# and .NET Core, focusing on shared and reusable platform components.

- Model, query, and optimize relational databases using SQL Server, PostgreSQL, or similar technologies.

- Develop and maintain Angular-based frontend components, including form-heavy and data-driven administrative screens.

- Apply RxJS and reactive programming patterns to handle async flows and state management.

- Work with messaging systems (RabbitMQ) to support asynchronous, event-driven communication.

- Use logging, search, and observability tools (Elastic stack or similar) to improve system visibility and reliability.

- Leverage AI-powered development tools (such as GitHub Copilot, Cursor, or similar) to improve productivity and code quality.

- Participate in architectural discussions around microservices, scalability, and system design.

- Support and guide teams during legacy-to-modern architecture migrations, providing hands-on technical input.

- Strong experience with C# and .NET Core.

- Solid experience with Entity Framework / EF Core, including query analysis and optimization.

- Strong knowledge of Angular, including modules, directives, dependency injection, and component communication.

- Strong SQL fundamentals and ability to write and reason about SELECT queries.

- Experience using AI-assisted development tools (Copilot, Cursor, AI-enabled IDEs).

- Ability to reason about code quality, performance, and best practices, not just write code.

- Comfortable discussing architecture and real-world trade-offs, especially in microservices contexts.

- Advanced English for technical discussions with international teams.

- Experience with platform or shared-services architectures.

-Exposure to microservices and distributed systems.

- Experience with cloud environments (AWS, Azure, or similar).

- Familiarity with CI/CD pipelines and DevOps practices.

- Background in enterprise or large-scale SaaS products.

- Platform-focused engineering team supporting multiple product squads.

- People First. We are all about people!

- Challenge yourself. There’s always room for improvement and continuous improvement is in our essence.

- Make it happen. Be ready to take challenges as they come. It’s all about attitude and commitment.

- We’re in this together. We work as a team, thrive as a team, and evolve as a team.

- Averaging on awesome. We work hard to deliver high-quality services and look forward to exceeding expectations.

- Keep it real. We promise you honesty, transparency, and openness, regardless of the situation.
