About us
We don't just look at the numbers; we are particularly looking for people who distinguish themselves through talent and motivation. So, if you believe this position is a perfect fit for you and we can benefit from each other, even if you don't (yet) meet all the criteria, we still look forward to your application.
As an AI Engineer, you will build the platform on which AI agents are deployed in companies. You will deal daily with the question of how AI agents create real added value – and implement the 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 capable digital employees.
- Agent Platform: You will develop and design the platform on which companies create and operate 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 will evaluate, integrate, and develop the latest approaches in agentic AI – Computer Use, Browser Use, MCP, Tool-Calling, and multi-agent architectures.
- Tool Integrations: You will build the bridge between AI and the real world of work: integrations into SharePoint, Outlook, Confluence, Teams, and other enterprise systems that enable agents to act.
- LLMs & Models: You will orchestrate state-of-the-art language models (OpenAI, Anthropic, Google, Mistral, Open Source) and optimize their use through prompting, RAG, and intelligent model selection.
- Coding Assistants: You will develop, test, and document with intensive use of LLM-based coding assistants.
- End-to-End: You will take responsibility for the entire development cycle – in a small, powerful team with short communication lines and direct impact on the product.
Your Profile
- You have a very good Master's degree in Computer Science or a comparable background.
- You live and breathe AI agents: Agentic AI, Tool Use, Multi-Agent Systems, Computer Use, and Browser Use are not buzzwords for you, but technologies you work with.
- You have comprehensive and up-to-date knowledge in the field of LLMs – models, benchmarks, frameworks, and agent-based architectures are familiar to you.
- You have experience with RAG systems, prompting strategies, and agentic systems.
- You have very good programming skills, ideally in Python and TypeScript with React/Next.js.
- You get the most out of LLM-based coding assistants: parallel sessions, MCP tools, Agent.md, workflow automation – and are constantly looking for ways to be even more productive.
- You are eager to take on real ownership in a young team and help shape a product.
- You have a high sense of responsibility and recognize risks early on.
- Through your motivation and self-discipline, you achieve a high standard of quality, deliver results on time, and motivate other team members.
- You use modern tools, including AI, to work more efficiently.
- Ideally, you have experience or interest in technologies for operating complex software systems, such as Docker, Kubernetes, CI/CD pipelines.
Why Us?
- Successful since 2017 – and today the core of a young group of companies with over 100 highly motivated and talented individuals.
- Short decision-making processes, the opportunity to contribute and make a difference.
- AI thrives on exchange: We organize events like the THINK REACTOR Meetup and regularly attend community gatherings like AI Tinkerers. Come by and get to know us!
- Access to all current AIs and AI tools (e.g., Cursor, Claude Code, Codex).
- Modern offices at the headquarters in Bremen and co-working spaces in Hamburg and Oldenburg.
- Company fitness, BusinessBike, and our own company boat.

JAAI's focus is on programming scalable AI solutions that create immediate added value for our clients. As soon as an AI solution is market-ready and records its first customers and revenues, it is spun off into a subsidiary and scaled there. To secure the growth of the spin-offs, equity is granted in the subsidiaries and strategic partners are brought on board.
Working in the JAAI Group is characterized by open communication. Problems are solved collaboratively in teams of top specialists from the fields of AI agents, natural language processing (LLMs), computer vision, big data, and robotics, as well as experienced IT managers and architects. Our mission: “Unlock Human Talent”. AI opens up new possibilities for the full potential of human talents by automating repetitive and time-consuming tasks.
