AI Engineer

Own the commercial layer that turns predictive output into something a commercial team actually uses. If you like building agentic AI systems and shipping them as real, production grade applications people touch every day, read on. Your new role You'll join our newly established data, insights and AI team in GCX, turning predictive intelligence into GenAI powered tools the commercial frontline relies on. You'll design and build agentic workflows and RAG pipelines, and take them from prototype through to secure, scalable production, working across the full stack from backend orchestration to the interfaces business users interact with. You'll operate within Lundbeck's federated AI engineering model, where GCX leads commercial use cases, domain-specific engineering and business outcomes. The role will work closely with the Enterprise AI Solutions & Engineering team, leveraging shared AI platforms, architecture patterns, engineering standards and reusable capabilities, while ensuring commercial solutions are production-ready and aligned with enterprise requirements. Your responsibilities will include: Generative AI and agentic development

• Designing and building commercial GenAI applications on enterprise LLM platforms
• Building commercial agentic AI workflows
• Developing and optimizing RAG architectures for business and technical use cases
• Integrating vector databases and semantic search to improve knowledge retrieval accuracy
• Building AI copilots, assistants and workflow automation
• Applying prompt engineering, evaluation and tuning to improve response quality, and optimizing model usage cost

Integration and orchestration

• Implementing Model Context Protocol (MCP) integrations to connect LLM applications with tools, data sources and business systems
• Designing reusable orchestration patterns across APIs, databases, files and enterprise knowledge repositories
• Designing context management, memory and tool calling strategies for AI agents
• Collaborating with the Enterprise AI Solutions & Engineering team to align commercial AI solutions with enterprise architecture, platform standards, security requirements and production readiness practices
• Contributing domain-specific patterns and learnings back into shared enterprise AI capabilities where relevant

Backend and frontend development for AI use cases

• Developing scalable backend services using Python (FastAPI, Flask or Django), RESTful APIs and microservices
• Designing and optimizing SQL databases for application and reporting needs
• Implementing authentication, authorization, logging and secure coding practices
• Building responsive web applications and dashboards using React/Next.js and TypeScript
• Integrating AI powered experiences into enterprise applications, working closely with product and business stakeholders

Operations (long-term)

• Containerizing services and deploying via cloud platforms
• Managing environments and automating deployment through CI/CD
• Monitoring performance, reliability and security in production
• Interpreting and visualizing model outputs for internal stakeholders, explaining AI concepts in plain terms

Your future team You'll join GCX's newly established data, insights and AI team, responsible for the commercial intelligence layer: building competitively differentiating predictive intelligence loops. We stay close to the business to make sure what we build actually gets used, in service of reaching millions of people living with serious chronic diseases. The team is young enough that you'll help shape its culture and ways of working. This is a build from scratch opportunity, not a seat on an established team. The position is based in Copenhagen, Denmark. What You Bring To The Team
