About the opportunity
Join QIAGEN Digital Insights, a global leader in bioinformatics software and knowledge solutions that help scientists transform complex molecular data into actionable biological insights. As an AI/ML Engineer, you will become part of a growing team developing next-generation AI solutions that support research across genomics, transcriptomics, and precision medicine.
Working closely with scientists, bioinformaticians, knowledge engineers, and software developers, you will design and deploy production-grade AI systems powered by Large Language Models (LLMs), agentic workflows, and advanced NLP technologies. This role offers the opportunity to work with cutting-edge technologies while contributing to products that make a meaningful impact on life science research and healthcare innovation.
Your tasks:
Design, develop, and maintain scalable AI services and MCP servers that enable access to QIAGEN's scientific data platforms, including Biomedical Knowledge Base, OmicSoft, IPA, and QCI.
Build and deploy high-performance microservices using Python, FastAPI, Docker, and asynchronous programming patterns.
Integrate and optimise Large Language Models through prompt engineering, Retrieval Augmented Generation (RAG), and vector-based retrieval approaches.
Develop robust ETL pipelines and data transformation frameworks across diverse biomedical and scientific data sources.
Enhance NLP and information extraction workflows, including entity recognition, relationship extraction, and scientific content processing.
Train, evaluate, and improve machine learning models that support literature curation, data acquisition, and knowledge discovery.
Contribute to software quality, observability, reliability, testing, and continuous improvement of production AI systems.
Your profile:
Core Technical Skills
Strong Python development skills, including asynchronous programming patterns (async/await), and experience building scalable microservices using FastAPI and Docker.
Expertise in MCP server development or protocol-driven system design, data API integrations (REST, GraphQL, and custom authentication), and robust testing practices including unit testing, integration testing, and error handling.
LLM & AI Systems
Hands-on experience working with leading LLM platforms (OpenAI, HuggingFace, Claude), including prompt engineering at scale, token management, cost optimisation, and structured output generation using frameworks such as Pydantic.
Proven knowledge of retrieval-augmented generation (RAG), vector embeddings, and agentic AI workflows using frameworks such as LangChain and LangGraph.
NLP & Machine Learning Fundamentals
Solid understanding of NLP concepts, including tokenisation, part-of-speech (POS) tagging, semantic and syntactic parsing, together with practical familiarity with embedding models such as Cross-Encoders, Bi-Encoders, and sentence-transformers.
Knowledge of core machine learning principles, including model training, evaluation metrics, and dataset management, with experience using PyTorch or TensorFlow (or a strong willingness to learn).
Domain & Practices
Degree in Computer Science, Bioinformatics, or a related discipline (or equivalent practical experience), with experience working with scientific or biological data considered advantageous.
Strong understanding of software engineering best practices, including version control, CI/CD pipelines, and code review processes to support high-quality software delivery.
