AWS Snowflake – Senior Data Engineer - Contractual role
Manager / Senior Manager
LEVEL | EXPERIENCE | DOMAIN | CORE PLATFORM |
Manager / Senior Manager | Manager: 12–14 years | Life Sciences preferred | AWS | Snowflake | Data Engineering |
Role purpose
Lead the engineering and implementation of enterprise-scale cloud data platforms using AWS and Snowflake. The role combines deep hands-on data engineering with technical leadership: translating architecture and business requirements into production-grade solutions that are scalable, secure, performant, supportable and cost-efficient.
Life Sciences / Pharma / Biotech / MedTech experience is preferred, particularly in regulated, high-volume or analytics-intensive data environments.
What you will own
• Design, build and optimize enterprise-scale data pipelines across AWS and Snowflake, spanning ingestion, transformation, consumption and operational monitoring.
• Engineer batch, near-real-time and streaming patterns for structured, semi-structured and unstructured data; translate solution architecture into detailed engineering designs and deployable components.
• Build reusable frameworks, utilities and engineering patterns rather than one-off pipelines; design for scalability, resilience, maintainability and operational support.
• Own technical delivery across design, build, testing, migration, deployment and production stabilization.
Core engineering accountabilities
Snowflake engineering — Build and optimize databases, schemas, tables, views, warehouses and data-sharing patterns; use Snowpipe, Streams & Tasks, Dynamic Tables and Snowpark where appropriate; optimize SQL, compute, concurrency, storage and cost; implement RBAC, masking and access policies.
AWS data engineering — Engineer solutions using relevant services such as S3, Glue, Lambda, Step Functions, DMS, Kinesis, IAM and CloudWatch; integrate cloud, SaaS, API, enterprise and on-premise sources; implement monitoring, logging, recovery and operational resilience.
ETL / ELT & integration — Design complex ETL/ELT pipelines, source-to-target mappings, transformation logic, reconciliation controls and orchestration; establish restartability, exception handling, auditability and standardized integration patterns.
Data modelling & quality — Implement logical and physical models for operational, reporting, analytics and AI use cases; automate completeness, validity, consistency, uniqueness and reconciliation controls; enable metadata, lineage and observability.
DevOps & engineering standards — Establish CI/CD, Infrastructure as Code, automated testing, version control, code review and release-management practices; improve engineering productivity through reusable components and automation.
Life Sciences experience – preferred
Experience with data platforms supporting one or more of the following domains is a strong advantage:
• Clinical Development / Clinical Operations
• Clinical Data Management & Biostatistics
• Pharmacovigilance / Drug Safety
• Regulatory Affairs
• Research & Discovery
• Medical Affairs
• Manufacturing & Quality
• Commercial / Patient Data
• Real-World Data / Real-World Evidence
The individual should understand that Life Sciences data engineering is not only about moving data. Data quality, traceability, lineage, controlled access and reproducibility can be as important as engineering performance. Experience in environments subject to GxP, 21 CFR Part 11, GDPR or other applicable privacy/regulatory requirements is advantageous.
