Type: Full-time
Company: Hatkom ApS (Tagart)About Tagart
Tagart is a product company, a spin-off of Hatkom ApS, a Danish Outsourcing company
Tagart builds an AI control layer for enterprise workflows — a unified orchestration platform that connects natural language interfaces with existing business systems.
We integrate OpenAI-powered agents with MCP (Model Context Protocol) servers to securely route natural language requests into APIs, GraphQL layers, and internal data sources. Our clients use Tagart to automate fund services, SaaS operations, and complex multi-system workflows.We’re looking for a full-stack engineer to strengthen the product team and help scale the architecture beyond the current MCP integration layer.
What you’ll work on
- Build and extend Tagart’s NestJS + Next.js stack (TypeScript, GraphQL, Prisma, PostgreSQL, Docker)
- Implement and connect MCP servers to wrap third-party APIs (e.g., Business Central, internal REST/GraphQL)
- Develop frontend interfaces for orchestrating AI agents and visualizing business workflows
- Work with OpenAI’s Agent SDK, SSE streaming, and multi-agent execution graphs
- Contribute to system architecture, logging/observability (OpenTelemetry, Winston, CloudWatch), and performance tuning
- Collaborate closely with the CTO and founding team to shape product direction and technical standards
We’re looking for
- Strong experience with TypeScript, Node.js (NestJS), and React (Next.js)
- Solid understanding of SQL databases, ORMs (Prisma), and API integration
- Familiarity with GraphQL (code-first schema design)
- Strong communication and ownership mindset — able to design, build, and ship features end-to-end
- Bonus:
- Experience with AI APIs (OpenAI, Anthropic) or agent frameworks
- Exposure to multi-tenant SaaS and enterprise integrations
- Background in data orchestration, workflow engines, or business automation
Why join Tagart
- Early engineering role in a deep-tech AI platform solving real enterprise problems
- Opportunity to shape the architecture, tooling, and roadmap
- Tight, senior founding team with strong engineering and product DNA
- Direct exposure to client pilots and production use cases
