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.\nYou'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.\nWhat you will:\nPipeline 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 \nRequirements validation: Partner closely with stakeholders to clarify requirements and critically examine them for assumptions, feasibility, consistency, and completeness throughout the design lifecycle \nEngineering standards: Shape modern data engineering practices across the team, including pipeline design patterns, data modeling conventions, schema governance, and resource optimization \nSolution design: Write technical specifications that weigh architectural options, trade-offs, and risks, recommending the best-fit tools and approaches \nData quality and reliability: Embed automated validation checks, dataset versioning, and pipeline monitoring across data products, and establish robust data lineage to ensure traceability \nPipeline maintenance: Maintain and continuously improve production pipelines through dependency and platform upgrades, refactoring, and technical debt reduction \nData partnerships: Coordinate with upstream data providers and downstream data consumers to establish data contracts, dependencies, and validation datasets \nML productionization: Partner with the MLOps team to turn experimental ML pipelines into robust, production-grade workflows \nAI-enabled development: Integrate coding agents into team workflows, such as automated pipeline-failure triage and fixes, with appropriate human oversight \nKnowledge building: Mentor team members through design discussions and constructive code reviews, and translate technical knowledge into clear, comprehensive documentation and onboarding materials \nWhat you should have\n5+ years of professional experience in data engineering \n3+ years of experience building and operating production-scale data pipelines using Python, SQL, and Spark (or similar distributed frameworks) \nExperience with workflow orchestration and CI/CD tools (e.g. Airflow, GitHub Actions) \nExperience processing semi-structured or unstructured text data (e.g. XML, JSON, or scanned documents) in production environments \n\nWhat we offer:\nExciting work in a great team, global projects, international environment\nOpportunity to learn and grow professionally within the company globally\nHybrid working model, flexible role pattern\nCompetitive salary & incentive pay\nPension and health insurance contributions\nInternal reward system and referral scheme\n5 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\nCafeteria for tax free benefits according to your choice (meal vouchers, sport, culture, health, travel, etc.), Multisport Card\nVodafone, Raiffeisen Bank, Foodora, and discount programs\nUp-to-date laptop and iPhone\nParking in the garage, showers, refreshments, massage chairs, library, music corner\nAdditional job details\nIn 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.
