About the Project
We are looking for Senior .NET and React Developers to join a project focused on building modern web applications.
The team follows an AI-first, agent-driven development approach, where engineers use AI-assisted tools as part of their daily workflow to plan, develop, test, and review solutions.
We are open to both full-stack engineers and candidates specializing in backend or frontend development separately.
Backend Requirements
Strong commercial experience with C#, modern .NET, and developing web applications and APIs.
Solid understanding of cloud-based architectures and backend system design.
Experience with AWS is a plus but not mandatory.
Candidates primarily focused on Python, Java, Rust, mobile, or desktop development may be less aligned with the current technology stack.
Frontend Requirements
Strong commercial experience with React.
Relevant experience with Vue.js is also valuable.
Ability to build modern, visually polished, and user-friendly web applications.
Experience with data-rich interfaces, dashboards, analytics, or real-time information displays is highly desirable.
Full-Stack Opportunities
Full-stack developers are also welcome, provided they combine strong frontend capabilities with practical experience in .NET backend development.
Engineering Approach
Work within an AI-first, agent-driven development environment.
Integrate AI tools into everyday development workflows.
Translate business requirements into actionable tasks and technical solutions.
Drive implementation with the support of AI-assisted tools.
Follow structured, specification-based development processes, including planning, implementation, testing, and code review.
Be comfortable using AI as a core productivity tool rather than relying exclusively on traditional development approaches.

Modern .NET
