Data Engineer (Snowflake)

Key Responsibilities

• Design, build, and operate end-to-end data pipelines (ingestion → transformation → serving) on Databricks and/or Snowflake, following medallion/layered architecture patterns
• Configure and administer workspaces/accounts — compute policies, resource sizing, environment setup, and access hierarchy — per the SDP reference architecture
• Implement data governance controls: catalogue and schema design, RBAC, row/column-level security, data masking, and lineage tracking
• Set up CI/CD and infrastructure-as-code for pipeline deployment and environment promotion (dev → test → prod)
• Configure monitoring, telemetry, and audit logging to meet SDP's central observability and security posture requirements
• Support UAT, integration testing, and parallel-run validation during migration and go-live
• Produce handover documentation (runbooks, access lists, escalation procedures) for agency operations teams
• Work directly with GovTech's SDP Central Team, agency stakeholders, and Principal (Databricks/Snowflake) solution architects throughout delivery

Required Technical Skills — Snowflake

• Virtual warehouse sizing, scaling, and cost/performance tuning

• Snow pipe and Snow pipe Streaming for continuous ingestion
• Snow park (Python/Scala) for in-warehouse data engineering
• Role-based access control (RBAC), secure data sharing, and object tagging for governance
• Query profiling and performance optimization (clustering keys, materialized views, caching)
• Time Travel, zero-copy cloning, and Snowflake's native data protection features
• Minimum 5 years of hands-on experience in Data Engineering, Data Platform Engineering, or related disciplines.
• Minimum 3 years of hands-on experience with Snowflakes involving data pipeline

Required Technical Skills — Common

• Strong SQL and Python (PySpark or general-purpose) for data engineering
• Data modeling — dimensional design, star/snowflake schemas, semantic layers
• CI/CD pipelines (e.g., Azure DevOps, GitHub Actions, GitLab CI) for data engineering workflows
• Infrastructure-as-code (Terraform preferred) for provisioning cloud data platform resources
• Hands-on experience on at least one hyper scaler — AWS, Azure, or Google Cloud
• Understanding of data security and compliance frameworks applicable to government/public-sector environments

Preferred Qualifications

• Databricks Certified Data Engineer Associate/Professional
• Snow Pro Core, or Snow Pro Advanced: Data Engineer
• Prior experience delivering on a government or regulated-sector data platform, or exposure to compliance frameworks such as IM8 is an add o n
• Experience working as part of a System Integrator (SI) delivery team alongside a platform Principal is an add on
