Senior AI Engineer
As a Senior AI Engineer in Genmab’s AI Lab, you’ll sit at the intersection of software engineering and applied AI. This role is about building robust, production-ready tools, using large language models (LLMs), agent-based frameworks, and modern cloud infrastructure to support drug discovery, clinical trials, and data-driven decision-making.
You’ll join a small, hands-on team working directly with domain experts across the company. Your focus will be to turn high-potential AI prototypes into scalable, useful tools that make an impact across the business from the lab to the field.
This is an engineering-focused role, not a traditional data science position. You’ll need to be comfortable designing systems, writing code, deploying to production, and supporting ongoing use all while staying aligned with Genmab’s mission to improve patients’ lives.
Responsibilities
- Architect and build multi-agent systems using frameworks like A2A or MCP to enable autonomous and human-in-the-loop workflows (e.g. document drafting, data analysis).
- Develop backend services with Python and FastAPI, and create light frontends with Streamlit or React when needed.
- Integrate systems with graph and vector databases (e.g. Neo4j, Pinecone) and Genmab’s data infrastructure on AWS.
- Embed AI tools (e.g. GitHub Copilot, Replit) into internal developer workflows to increase efficiency and adoption.
- Own the path from prototype to production, ensuring tools are reliable, secure, and scalable—avoiding throwaway solutions. Collaborate across teams, understanding business needs and translating them into technical solutions with real-world value.
- Explore and apply emerging AI technologies, sharing insights internally and supporting a culture of learning and experimentation.
Requirements
- 8+ years of experience in software or ML engineering, including 1+ year working with applied LLMs (e.g. RAG, agents, context engineering).
- Strong software engineering skills with Python (FastAPI, backend development) and some experience with JavaScript/TypeScript (React/Next.js) preferred.
- Familiarity with one or more agent frameworks (e.g. LangGraph, LangChain, AutoGen, AgentSDK) and orchestration libraries.
- Understanding of ML fundamentals: transformers, embeddings, vector search, and evaluation methodologies.
- Experience working with cloud infrastructure and dev ops tools for production deployment (preferably AWS).
- Strong communication skills able to collaborate with scientists, engineers, and business teams.
- A self-starter with a strong sense of ownership, eager to explore new technologies and solve meaningful problems.
- Interest in life sciences or the biotech/pharma space is a big plus—but domain expertise is not required on day one.
