Data Engineer (Snowflake)
Summary
Builds and operates end-to-end data pipelines on Snowflake (and Databricks) for GovTech's Singapore Data Platform, covering warehouse sizing and tuning, ingestion via Snowpipe, governance (RBAC, masking, lineage), CI/CD with Terraform, and monitoring, then hands over runbooks to agency operations teams.
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
