This is a hands‑on senior engineering role at the intersection of data engineering, Data DevOps, cloud platform engineering, and production reliability. The role owns Data Platform infrastructure and automation within the data domain while partnering with enterprise Infrastructure and Security teams on underlying cloud, networking, identity, and security services.

You will own major platform capabilities end to end — from architecture and automation through production operation, reliability, and continuous improvement.

Responsibilities:

• Own the Data DevOps framework, standards and automation across Snowflake and AWS RDS/Aurora database platforms.
• Establish source‑controlled schema versioning, database migration workflows, environment promotion, deployment validation, and deployment rollback practices.
• Implement Snowflake CI/CD and database deployment using schemachange or equivalent tooling.
• Implement automated schema migration and versioning for AWS RDS/Aurora databases using Flyway or equivalent tooling.
• Automate Snowflake roles, grants, policies, and supported configuration through Infrastructure as Code.
• Reduce routine direct production changes through repeatable, auditable deployment workflows.
• Establish platform standards for dbt and Apache Airflow / Amazon MWAA.
• Build and maintain reusable CI/CD patterns for transformations, pipelines, dependencies, configuration, testing, and environment promotion.
• Partner with Data Engineers and Data Quality Engineering to provide platform capabilities for automated validation and quality gates.
• Improve release traceability, deployment consistency, rollback, and production readiness.
• Enable metadata, lineage, and quality information to integrate with DataHub and monitoring platforms.
• Build reusable Infrastructure‑as‑Code capabilities using Terraform.
• Standardize deployment and configuration across AWS Glue, S3, EKS, MWAA, DataHub, and Grafana.
• Develop consistent GitOps and CI/CD workflows using GitHub Actions.
• Manage Kubernetes‑based data‑platform services using EKS, Helm, and source‑controlled configuration.
• Automate environment provisioning, configuration management, secrets, access controls, and infrastructure promotion.
• Own the operational health of shared data‑platform services.
• Build shared monitoring and observability capabilities using Grafana and CloudWatch.
• Establish actionable alerts, runbooks, service‑health measures, and escalation procedures.
• Implement least‑privilege access, service identities, secrets management, and separation between individual and automated production access.
• Support DataHub platform engineering and technical integrations for metadata, lineage, quality, and governance enablement.
• Build reusable templates, modules, deployment workflows, standards, and tooling for Data Engineers.
• Lead data platform architecture decisions and evaluate trade‑offs across reliability, performance, maintainability, security, and cost.
• Monitor platform utilization and identify opportunities to improve performance and cloud cost efficiency.

Basic Qualifications:

• Bachelor’s degree from an accredited, not‑for‑profit, in‑person University or College.
• 7+ years of experience in Data Platform Engineering, Data Engineering, Software Engineering, DevOps, SRE, Cloud Engineering, or a related discipline.
• Demonstrated experience building and operating production data platforms.
• Hands‑on production experience with Snowflake, including schema management, security, CI/CD and deployment automation.
• Strong experience with Infrastructure as Code, Terraform, CI/CD, and AWS data platform services including Aurora/RDS, S3 and Glue.
• Experience with dbt and Apache Airflow, preferably Amazon MWAA.
• Production experience with Kubernetes, preferably Amazon EKS, and deployment tooling such as Helm.
• Strong scripting or software‑development skills, preferably Python.

Preferred Qualifications:

• DataHub or similar metadata/catalog platforms.
