Job Description

About this role

Enterprise software is going through its biggest shift in decades. Applications are moving from deterministic workflows to intelligent, agentic systems that understand context, remember preferences, and act on behalf of users. This isn’t a future prediction — it’s happening now, and Columbus is building at the frontier of it.

We’re hiring three senior engineers to form the core of our Group AI engineering team. Together, you’ll design and build the next generation of AI-powered systems that will transform how thousands of people work — across the Nordics and beyond. You’ll work directly with the VP Group AI. No layers. No committees. You build, you ship, you learn.

This is not a consulting engagement or a proof-of-concept. It’s production engineering at enterprise scale, on the Microsoft platform, using the most advanced AI models available today.

We are looking for someone who have/is

• Strong expertise in LLM application design, including prompt engineering, agent frameworks, and evaluation
• Good undetstanding of data as a foundation for AI driven Insights
• Experience building scalable, production-grade AI systems, with focus on context management, cost optimization, and real-world deployment
• Proven ability to design multi-agent architectures where AI systems collaborate effectively
• Hands-on experience with Microsoft 365 ecosystem (Graph, Teams, SharePoint) and cloud-native platforms like Azure
• Solid background in data and retrieval systems, including vector search, embeddings, document databases, and RAG architectures
• Skilled in building robust, event-driven and API-based systems with strong focus on reliability, security, and enterprise compliance

You have hands-on experience with Microsoft Graph, Teams, SharePoint, and the broader Microsoft 365 ecosystem. In addition, you possess expert knowledge of AI Security and AI Governance as they relate to automation, integrations, and enterprise-scale AI solutions.

AI Infrastructure

You bring extensive experience with document databases, vector search technologies, and embedding models. You understand RAG architectures, including chunking, reranking, hybrid search, and citation grounding, and can design data governance frameworks that meet enterprise compliance requirements such as DLP, auditing, and retention. You have experience building scalable knowledge retrieval systems, supported by expert knowledge of AI Security and AI Governance.
