About the Role

Join an international enterprise project for a US-based client in the Government Asset Management domain. The team is building a large-scale web application used to manage and track government-owned assets while meeting strict security, compliance, and audit requirements.

This is a backend-oriented Full Stack role with approximately 60% .NET / 40% Angular. Although backend development is the primary focus, we're looking for an engineer who can take ownership of the frontend architecture and establish a solid foundation for future development.

AI is an integral part of the engineering workflow. We expect developers to actively leverage AI-powered tools on a daily basis to improve productivity, code quality, and software delivery.

Requirements

• Design, develop, and maintain scalable backend services using .NET and C#.
• Develop and maintain Angular applications for enterprise web solutions.
• Build and own the frontend architecture, including project structure, reusable components, shared libraries, and engineering standards.
• Create a frontend foundation that enables other developers to easily extend the application with new features.
• Design and implement REST APIs and integrate frontend and backend components.
• Participate in architecture discussions and technical decision-making.
• Work with AI-powered development tools as part of the daily engineering workflow.
• Collaborate closely with cross-functional engineering teams throughout the software development lifecycle.

Must Have

• 5+ years of commercial software development experience.
• Strong expertise with .NET and C#.
• Strong hands-on Angular experience.
• Proven ability to build Angular applications from scratch, including project structure, architecture, reusable components, and shared modules.
• Experience developing complete frontend features, not only maintaining existing functionality.
• Experience building and maintaining production-grade enterprise web applications.
• Strong understanding of software architecture, design patterns, and engineering best practices.
• Experience working with REST APIs, microservices, and cloud-based applications.
• Ability to work independently and take ownership of technical solutions.
• Practical experience using AI-powered development tools such as Cursor, GitHub Copilot, Claude, ChatGPT, Windsurf, or similar.
• Experience integrating AI services and APIs into applications.
• Upper-Intermediate or higher English.

Nice to Have

• Experience with Azure or AWS.
• Experience with AI agents, MCP, RAG, or prompt engineering.
• Experience designing scalable frontend architectures for enterprise applications.
• Experience mentoring developers or leading frontend initiatives.

What We’re Looking For

We are not necessarily looking for an AI Engineer. We are looking for a strong Senior Full Stack Developer who actively embraces modern AI-driven development practices, learns quickly, and is excited about building software in a new way.

The ideal candidate is technically strong, highly independent, curious about AI, and comfortable working directly with clients and stakeholders.
