.NET Developer – AI Integration

We're developing an AI-powered assistant for a major client, integrated into Microsoft Teams, that helps users accomplish more with less effort. This isn't research — it's a production system that you'll build, scale, and continuously improve.

You'll work hands-on with .NET and Python, using Azure services, and be a core contributor in shaping how the solution evolves.

What you need to have:

• 2-3 years of hands-on software development experience
• Solid experience in .NET (C#) — this is your main long-term stack
• Good working knowledge of Python or readiness to use it where needed
• Familiarity with Azure, DevOps workflows, and backend APIs
• An advantage: Some experience with React/web UI
• Strong problem-solving skills, self-management, and clear communication
• Very good command of English and Estonian

What you'll need to do:

• Work on production-grade systems, not just prototypes
• Understand how the system works, identify conceptual issues, and propose improvements
• Switch between tools as needed, while staying grounded in .NET
• Integrate AI technologies into practical use cases
• Collaborate closely with the team to find the best solutions for clients' business needs
• Write clean, scalable, and unit-tested code

What is in it for you?

• Comfortable office in Tallinn or Tartu, with parking available
• A culture of autonomy, trust, and entrepreneurship
• Being part of a large group of engaged experts
• Flat organization and the possibility to work very closely with decision-makers
• Opportunities for training, self-development, learning through a community of analysts, and applying the latest research
• Healthy work-life balance with flexible hybrid working options
• Supplementary health insurance
• Opportunities to engage in a variety of sports, including volleyball, football, and badminton, along with sports compensation
• Participating in enjoyable team events, hikes, and other engaging activities at Helmes
