It operates at the intersection of clinical operations, data science, digital platforms, external partners, and global regulatory expectations, requiring solutions that are scalable, compliant, user-centered, and trusted across diverse stakeholders.\n\nDigital platforms, data products, and AI-enabled capabilities are increasingly essential to improving clinical trial planning, execution, monitoring, and decision-making. This role helps deliver responsible technology solutions that strengthen data quality, reduce operational complexity, support audit readiness, and enhance the experience of clinical teams, investigators, and participants while keeping participant safety at the center of the domain\n\nAs a Sr. Associate, AI and Analytics Data Engineer, you will be part of a global team responsible for engineering the trusted, scalable, and governed data foundation for a major AI-driven platform serving the Clinical Development and Operations domain. You will design and build reusable data products, pipelines, and processing frameworks that integrate complex clinical, operational, and external data; enable advanced analytics, machine learning, and generative AI use cases; and meet enterprise expectations for security, privacy, quality, lineage, reliability, and regulatory compliance.\n\nJoin our diverse team in making an impact on patient health through the application of cutting-edge technology and collaboration.\n\ndescription\n\nDesign, build, test, and operate scalable batch and streaming data pipelines that ingest, standardize, and integrate clinical, operational, scientific, and external data for a major AI-driven clinical platform.\n\nDevelop curated, reusable, and well-documented data products and feature-ready datasets that enable analytics, machine learning, generative AI, and agentic AI use cases.\n\nImplement robust data modeling, transformation, metadata, lineage, and master/reference data patterns across data lake, lakehouse, warehouse, and application-serving layers.\n\nEngineer automated data-quality controls, reconciliation, observability, alerting, and recovery capabilities to support trusted and reliable AI outcomes.\n\nOptimize pipeline performance, scalability, availability, and cloud cost while supporting high-volume and diverse clinical data workloads.\n\nApply DataOps, continuous integration and continuous delivery, infrastructure-as-code, automated testing, and version-control practices across development and production environments.\n\nPartner with clinical domain experts, data scientists, machine learning engineers, architects, security, privacy, and platform teams to translate AI use-case needs into production-grade data solutions.\n\nEmbed security, privacy, consent, access controls, auditability, and applicable regulatory requirements into data-engineering designs and delivery practices.\n\nTroubleshoot complex data and production issues, perform root-cause analysis, and drive sustainable remediation and operational improvements.\n\nContribute to engineering standards, reusable frameworks, technical documentation, code reviews, and mentoring that improve delivery consistency and platform adoption across teams.\n\nBASIC QUALIFICATIONS\n\nBachelor’s degree in Computer Science, Data Engineering, Software Engineering, Information Systems, Engineering, or a related discipline.\n\n3+ years of hands-on data engineering or software engineering experience designing, building, deploying, and supporting production-grade data pipelines, data platforms, or data-intensive applications.\n\nAdvanced proficiency in Python and SQL, including object-oriented programming, complex query development, data transformation, performance tuning, automated testing, debugging, and reusable framework development.\n\nHands-on experience implementing scalable batch and streaming pipelines using technologies such as Apache Spark, Databricks, Airflow, Kafka, or comparable distributed data-processing and orchestration tools.\n\nExperience with cloud data engineering services, preferably Amazon Web Services, including object storage, serverless compute, data integration, cataloging, messaging, monitoring, identity, and access-management capabilities.\n\nExperience designing data-lake, lakehouse, and warehouse solutions using platforms such as Snowflake or Databricks, including partitioning, file formats, schema evolution, workload optimization, and cost-performance management.\n\nStrong knowledge of dimensional, relational, canonical, and domain-oriented data modeling, with experience creating curated data layers, reusable data products, and application-ready datasets.\n\nExperience integrating structured, semi-structured, and unstructured data through extract-load-transform and extract-transform-load patterns, application programming interfaces, event streams, files, and database connectors.\n\nExperience implementing data-quality controls, reconciliation, schema validation, metadata management, lineage, observability, alerting, error handling, restartability, and service-level monitoring.\n\nProficiency with software engineering and DataOps practices, including Git, branching strategies, code reviews, unit and integration testing, continuous integration and continuous delivery, environment promotion, and release automation.\n\nUnderstanding of secure data-engineering patterns, including role-based access, encryption, secrets management, data masking, privacy controls, audit logging, retention, and regulated-data handling.\n\nStrong analytical, production troubleshooting, root-cause analysis, technical documentation, and communication skills, with the ability to deliver independently and collaborate across global product, platform, architecture, analytics, and clinical teams.\n\nPREFERRED QUALIFICATIONS\n\nAdvanced degree in Data Engineering, Computer Science, Data Science, Information Systems, Engineering, or a related discipline.\n\nExperience engineering data for enterprise artificial intelligence and machine learning platforms, including feature pipelines, model-training and evaluation datasets, embeddings, vector stores, semantic data preparation, retrieval-augmented generation, and model monitoring.\n\nExperience with medallion or layered lakehouse architectures, open table formats such as Delta Lake, Apache Iceberg, or Apache Hudi, and distributed processing of high-volume datasets.\n\nExperience building reusable ingestion and transformation frameworks, metadata-driven pipelines, data contracts, schema registries, and self-service data capabilities.\n\nExperience with infrastructure as code, containerization, and orchestration technologies such as Terraform, Docker, and Kubernetes.\n\nExperience with application programming interface development, event-driven architecture, microservices, and operational data-serving patterns that support real-time AI and analytics applications.\n\nKnowledge of clinical development and operations data, including clinical trial management, electronic data capture, safety, laboratory, site, monitoring, document, submission, and regulatory data.\n\nFamiliarity with clinical and healthcare data standards and controlled terminology, including Clinical Data Interchange Standards Consortium standards, Health Level Seven Fast Healthcare Interoperability Resources, or equivalent industry models.\n\nExperience working in a regulated life-sciences environment with data integrity, validation, privacy, consent, audit readiness, and computerized-system compliance expectations.\n\nCloud, data platform, or data engineering certifications in Amazon Web Services,
