Product that needs your engagement
You will be at the heart of building a new generation web-based application fully powered by AI technologies. This product is envisioned as a cutting-edge tool that redefines how professionals interact with complex data and workflows. We’re not just adding AI features into an existing app — we are designing an AI-first experience from the ground up, where automation, personalization, and intelligence are embedded in every interaction. The application will combine scalability, intuitive UX, and deep AI integration to create a solution that is both technically robust and delightful to use.

Your future team of professionals
You will join an ambitious and growing team that values collaboration, ownership, and thoughtful engineering. You will work closely with Backend and Frontend Engineers, a Product Manager, and a QA Engineer, contributing to the development of the product and helping shape its technical direction as the team continues to grow.

Your future challenges & opportunities
Opportunities
Direct involvement in the launch of a new product, with real impact on architecture and technical decisions.
Hands-on experience building DWH integrations and MCP-based AI pipelines — one of the most in-demand skill sets in 2026.
Work at the intersection of backend engineering and AI, expanding expertise beyond traditional .NET development.
Opportunity to define integration patterns and technical standards from the ground up, rather than maintaining legacy code.
Exposure to the full product lifecycle: from data modeling and API design to production deployment and optimization.

Challenges
Proactively learn and adopt MCP, a recently introduced standard, keeping pace with a fast-evolving ecosystem.
Design and implement DWH integrations with careful data modeling and schema planning — early mistakes can be costly.
Balance product launch deadlines with the need to maintain clean, scalable, and maintainable architecture under pressure.
Work across multiple technical domains simultaneously: data pipelines, API development, and AI tool integration.
Validate and responsibly apply AI-assisted development tools, avoiding over-reliance on generated output.

Impact you will make
Design, build, and maintain scalable back-end services and APIs using C# and the .NET ecosystem, ensuring high performance, reliability, and maintainability.
Ensure security, performance, and reliability across server-side components by applying SOLID principles, established design patterns, and back-end best practices.
Write clean, testable, and well-documented code that meets team coding standards and supports efficient code reviews.
Collaborate closely with front-end developers to design and integrate RESTful or GraphQL APIs that power seamless user experiences.
Participate in code reviews and contribute to the continuous improvement of team engineering practices and standards.
Optimize application performance, database queries, and system throughput to handle high-load environments efficiently.
Conduct thorough testing and debugging to deliver high-quality, production-ready software.

Skills we are looking for
At least 5 years of experience as a .NET Developer (ASP.NET Core, Entity Framework Core), preferably in a tech-focused environment.
Higher education in Computer Science, Information Technology, or a related field (relevant certifications are a plus).
Deep understanding of software principles: SOLID, IoC, OOP, design patterns, and client/server architecture.
Experience designing and building RESTful APIs and microservices.
Experience with version control using Git and collaborative workflows (branching, pull requests, reviews).
Familiarity with authentication concepts and secure application development (OAuth2, JWT).
Experience with relational databases and ORM tools (SQL Server, PostgreSQL, Entity Framework Core).
Experience with testing frameworks (xUnit, NUnit, Moq).
Knowledge of Docker/docker-compose and basic CI/CD processes.
Performance optimization skills: profiling .NET applications, identifying bottlenecks, and improving throughput.
Ability to effectively use AI-assisted development tools (GitHub Copilot, ChatGPT, etc.), understand their limitations, and responsibly apply them in the development workflow.
