Your tasks

HUB.KI is the newest spin-off of the JAAI Group: a sovereign AI platform that enables companies to create, share, and productively deploy AI assistants, digital employees, and automated workflows. GDPR-compliant, European, and deployable from SaaS to on-premise. Something big is taking shape here, and you can help build it from the start. As an AI Engineer, you build the platform that brings AI agents into companies. Every day, you work on the question of how AI agents can create real business value and turn those answers into product features. Your playground: state-of-the-art technologies such as Computer Use, Browser Use, MCP, and tool integrations that turn language models into action-oriented digital employees.

• Agent Platform: You develop and shape the platform on which companies create and run their AI agents, from simple assistants to autonomous digital employees that act across multiple steps, systems, and data sources
• State-of-the-Art Agent Technologies: You evaluate, integrate, and develop the latest approaches in Agentic AI, including Computer Use, Browser Use, MCP, tool calling, and multi-agent architectures
• Tool Integrations: You build the bridge between AI and the real working world through integrations with SharePoint, Outlook, Confluence, Teams, and other enterprise systems that enable agents to take action
• LLMs & Models: You orchestrate state-of-the-art language models (OpenAI, Anthropic, Google, Mistral, open source) and optimize their use through prompting, RAG, and smart model selection
• Coding Assistants: You develop, test, and document while making the most intensive use of LLM-based coding assistants
• End-to-End: You take responsibility across the full development lifecycle in a small, high-impact team with short decision paths and direct influence on the product

Your profile

• You hold an excellent Master's degree in Computer Science or have a comparable background
• You live and breathe AI agents: Agentic AI, tool use, multi-agent systems, Computer Use, and Browser Use are not buzzwords to you but technologies you actively work with
• You have extensive and up-to-date knowledge of LLMs: models, benchmarks, frameworks, and agent-based architectures are familiar territory
• You have experience with RAG systems, prompting strategies, and agentic systems
• You have very strong programming skills, ideally in Python and TypeScript with React/Next.js
• You get the maximum out of LLM-based coding assistants: parallel sessions, MCP tools, Agent.md, workflow automation, and you are constantly looking for ways to become even more productive
• You ideally have experience with or interest in technologies for running complex software systems, such as Docker, Kubernetes, and CI/CD pipelines
• You are excited to take real ownership in a young team and help shape a product
• You have a strong sense of responsibility and identify risks early on
• Through your motivation and self-discipline, you achieve a high quality standard, deliver results on time, and motivate other team members
• You use modern tools, including AI, to work more efficiently
