The Role
Hybrid (3 days onsite / 2 days remote)
We are looking for a Senior Full Stack Developer who works AI-first: someone who uses AI tools and AI-driven development methods as a natural part of how they build software, and who helps the whole team do the same. You will design and ship full-stack features across our .NET backend and modern frontend, and drive the adoption of AI-driven development practices (including AI-DLC) across the engineering team.
This is a hands-on engineering role, not a people-management role. You will lead AI initiatives and automation projects, and act as a technical reference and multiplier for the team. This is not a data science position: we are looking for engineers who build production software with AI.
Key Responsibilities
- Build and maintain full-stack features end-to-end: C#/.NET Core APIs and modern frontend applications (Angular, React, or TypeScript-based stacks)
- Use AI-driven development workflows daily (Claude Code, Claude, Cursor, and similar tools) to design, implement, test, and review software, and define how the team applies them
- Apply and evolve the AI-DLC (AI-Driven Development Lifecycle) across the team: practices, guardrails, standards, and reusable playbooks
- Design and implement automation initiatives that improve team productivity and product quality
- Contribute to MCP (Model Context Protocol) server setups that connect AI tools to internal systems
- Help define data security practices for information shared with external AI services
- Contribute to architecture decisions and share knowledge through code reviews, pairing, and internal training
Requirements
What You Bring
- 5+ years of full-stack development experience, with strong C#, .NET Core, and Web API skills
- Solid frontend experience with Angular (preferred), React, or TypeScript
- Demonstrated, day-to-day experience working AI-first with Claude Code, Claude, Cursor, or similar tools, not just occasionally
- Hands-on experience with AI-driven development methods (AI-DLC or equivalent), and a clear point of view on where AI helps and where it needs human control
- Experience with MCP or other ways of connecting AI tools to systems is an asset
- Good judgment on AI data security and responsible use of AI tools
- Experience with SQL Server and with Azure or AWS
- Ability to share knowledge and coach peers on AI-assisted workflows
- Professional working proficiency in English and French
Tech Stack Backend: C#, .NET, .NET Core, Web API, REST, Entity Framework
Frontend: Angular, React, TypeScript AI Tools: Claude Code, Claude, Cursor, MCP Cloud & Data: Azure (Azure DevOps), AWS, SQL Server
