combines the two core competencies of Data Science and Software to deliver a unique service offering, bringing together a team of experts in data analytics, statistics, programming, databases and project management. Datahouse is a wholly owned subsidiary of the Wüest Partner Group

What you'll do

• work with the AI Solution Architect to design and build the shared AI foundations behind the Wüest Partner Group's products. That includes agent frameworks, tool and data integrations, evaluation pipelines and governance. You make sure they can be reused across companies and use cases
• own the technical side of projects where AI agents plan, use tools and carry out multi-step workflows. You see them through from design to production
• set the standards for evaluation, guardrails, human-in-the-loop design, security (permissions, prompt injection, etc.), cost and latency control
• define reference architectures, reusable components and best practices across the AI engineers, including the right use of retrieval and context engineering
• review designs and code, mentor engineers and raise the technical bar
• take part in scoping, effort estimates and technical pre-sales, and explain trade-offs (autonomy versus control, quality, cost, risk) in plain terms
• Work with clients and the group:
• assess new models, agent frameworks and protocols such as MCP, and decide what is ready for production

Qualifications

• 5+ years in software, data or ML engineering, including significant hands-on experience building LLM-based systems in production
• Proven experience with agentic systems: tool and function calling, multi-step and multi-agent orchestration, state and memory management, and integration with APIs and enterprise systems
• A clear method for evaluating and testing non-deterministic systems
• Solid understanding of retrieval and context engineering as building blocks, not an end in themselves
• Strong Python skills and very good software engineering practice (APIs, CI/CD, containers)
• Experience setting technical direction for others, as a tech lead, staff engineer or similar
• Awareness of data protection and regulatory requirements (Swiss nDSG, EU AI Act)
• Excellent English language skills; German is a plus
