Senior AI/ML Data Engineer 

Job Description
Senior AI/ML Data Engineer
The Senior AI/ML Data Engineer owns the production pipelines that turn unstructured text and documents into reliable, model-ready data for our team's Generative AI and Natural Language Processing (NLP) applications and services. Key focus areas will include engineering data products built from licensed scientific literature, patents, clinical trials, and more. You'll build and maintain ingestion and parsing pipelines for unstructured or semi-structured text data with data-quality checks built in, govern data lineage and usage compliance for AI applications, and configure the search indices built on this data. You'll also build shared pipeline components and deployment patterns used across the team. These data products support critical use cases spanning early-stage scientific research to post-market surveillance, including systematic literature reviews, competitive intelligence, target identification, and safety monitoring.
You'll work directly alongside the data scientists and scientific subject matter experts who use your data. You will have the autonomy to propose better ways to build, see your work accelerate research, and ultimately help bring therapeutics to patients. As you grow, you'll have opportunities to expand into emerging areas, such as large language model (LLM)-powered document parsing and metadata enrichment. The position is embedded within a cross-disciplinary team of data scientists, bioinformaticians, and engineers dedicated to using cutting-edge AI/ML and data science techniques to drive drug discovery and development.
What you will:
Pipeline delivery: Build and run production pipelines hands-on that turn unstructured text into reliable data products, and drive the technical execution of complex data initiatives
Requirements validation: Partner closely with stakeholders to clarify requirements and critically examine them for assumptions, feasibility, consistency, and completeness throughout the design lifecycle
Engineering standards: Shape modern data engineering practices across the team, including pipeline design patterns, data modeling conventions, schema governance, and resource optimization
Solution design: Write technical specifications that weigh architectural options, trade-offs, and risks, recommending the best-fit tools and approaches
Data quality and reliability: Embed automated validation checks, dataset versioning, and pipeline monitoring across data products, and establish robust data lineage to ensure traceability
Pipeline maintenance: Maintain and continuously improve production pipelines through dependency and platform upgrades, refactoring, and technical debt reduction
Data partnerships: Coordinate with upstream data providers and downstream data consumers to establish data contracts, dependencies, and validation datasets
ML productionization: Partner with the MLOps team to turn experimental ML pipelines into robust, production-grade workflows
AI-enabled development: Integrate coding agents into team workflows, such as automated pipeline-failure triage and fixes, with appropriate human oversight
Knowledge building: Mentor team members through design discussions and constructive code reviews, and translate technical knowledge into clear, comprehensive documentation and onboarding materials
What you should have
5+ years of professional experience in data engineering
3+ years of experience building and operating production-scale data pipelines using Python, SQL, and Spark (or similar distributed frameworks)
Experience with workflow orchestration and CI/CD tools (e.g. Airflow, GitHub Actions)
Experience processing semi-structured or unstructured text data (e.g. XML, JSON, or scanned documents) in production environments
What we offer:
Exciting work in a great team, global projects, international environment
Opportunity to learn and grow professionally within the company globally
Hybrid working model, flexible role pattern
Competitive salary & incentive pay
Pension and health insurance contributions
Internal reward system and referral scheme
5 weeks annual leave, 5 sick days, 15 days of certified sick leave paid above statutory requirements annually, 40 paid hours annually for volunteering activities, 12 weeks of parental contribution

Additional job details
In addition to building and maintaining our suite of tools, our team consults on how software capabilities, data products, and AI/ML can support the projects of our 5,000+ stakeholders (scientists, engineers, regulatory liaisons, data scientists, etc.) across our multi-national organization. We strive to enhance data science, NLP, and AI literacy across these groups.
As part of our work, our team has opportunities to coauthor internal and external presentations, white papers, manuscripts, and/or open-source code releases. We invest in your professional growth by providing access to specialized learning platforms, opportunities to attend industry conferences, participation in internal communities of practice, and the chance to learn the science of drug discovery and development directly from domain experts.
