Core Technologies: Proficiency with Python and SQL; hands-on experience with Snowflake, AWS (e.g., S3, Lambda), Amazon Redshift, Apache Spark, and Apache Airflow. Familiarity with MongoDB, Oracle, Teradata, and/or SQL Server.
Data Engineering Skills: Strong track record building ETL/ELT pipelines, integrating diverse sources, orchestrating workflows, and implementing data quality, lineage, and governance. Proven performance tuning and scalability practices.
Statistical & Analytical Expertise: Solid grounding in statistics, experimental design, and advanced analytics, with the ability to translate business problems into data science solutions and validate outputs rigorously.
Healthcare Data Expertise: Hands-on experience working with EMR/EHR, claims, laboratory, and epidemiological datasets, with a strong understanding of healthcare data models, standards, and challenges.
Analytics & DS Fundamentals: Ability to translate business logic into technical requirements and analytical datasets; experience supporting feature engineering and model operations; proficiency in data manipulation, cleansing, and interpretation; ability to analyze results and present findings.
Business & Domain Context: Ability to bridge data science, epidemiology, and business context, ensuring solutions are impactful and aligned with commercial and healthcare objectives.
Communication & Collaboration: Clear written and verbal communication to convey complex methods and outcomes to technical and non-technical stakeholders; comfortable working cross-functionally and in cross-cultural environments.
Operational Excellence: Experience with support/maintenance projects, ticket handling, and change management; experience with Git and CI/CD workflows.
Agentic AI & Advanced AI Systems: Experience designing or working with Agentic AI frameworks, multi-agent systems, or autonomous decision pipelines, including orchestration of AI agents for complex problem-solving.
Model Enablement: Partner with Commercial Data Science and Advanced Analytics teams to translate business logic into technical requirements; prepare analytical datasets and features; optimize queries and data flows for model training, scoring, and monitoring.
Applied Analytics: Conduct analyses using HCP and de-identified patient-level healthcare data to generate disease insights, lead generation, targeting, segmentation, and field alerts; maintain scalable analytical assets for recurring use cases.
Methods & Tools: Contribute to predictive modeling workflows (e.g., regression, classification, clustering, time series); support development and optimization of ML tools that improve patient finding and HCP identification; build dashboards and reports in Tableau, Power BI, Qlik, or Databricks/Dataiku notebooks.
Collaboration: Work with Commercial partners and the internal AI community to identify value-driving opportunities and share best practices; support ad hoc analyses and production operations as needed.
Big Data & Distributed Computing: Knowledge of Hive, Spark, Scala, HDFS; designing solutions for large-scale distributed environments.
APIs & Integration: Experience with HTTP requests/responses and RESTful services for data ingestion and application integration.
Visualization & BI: Experience with Tableau, Qlik, Power BI, and Excel-based reporting.
Domain & Tools: Working knowledge of Salesforce/Veeva CRM, data governance practices, and data mining algorithms; consulting, healthcare, or biopharma experience; hands-on work with EHR, claims, and lab data ecosystems.
ML Enablement: Experience operationalizing ML pipelines (training, scoring, monitoring) and optimizing data flows for model performance in Databricks or Dataiku.
When we put unexpected teams in the same room, we unleash bold thinking with the power to inspire life-changing medicines. In-person working gives us the platform we need to connect, work at pace and challenge perceptions. That's why we work, on average, a minimum of three days per week from the office. But that doesn't mean we're not flexible. We balance the expectation of being in the office while respecting individual flexibility. Join us in our unique and ambitious world.
At AstraZeneca's Alexion division for Rare Diseases, you'll find an environment where innovation thrives! Our commitment to patients drives us forward every day. Here you'll be part of a team that values diversity of thought as much as diversity of people. We believe in empowering our employees through tailored development programs that align personal growth with our mission. With a rapidly expanding portfolio in a dynamic biotech atmosphere combined with the resources of a global biopharma leader—your career here is more than just a path—it's a journey towards making a difference where it truly counts.
