- Oversee the operational health, security, backup, and scalability of PostgreSQL (AWS RDS/Aurora) and Snowflake environments to ensure high availability and reliability.
- Act as a database performance escalation point, diagnosing and resolving critical production issues with minimal downtime.
- Collaborate closely with software engineers to review database schemas and SQL queries, enforcing best practices before production deployment.
- Contribute to data architecture decisions and ensure systems are designed for efficiency, scalability, and long-term maintainability.
Requirements:
- 5 years of experience in Database Administration, Database Engineering, or a data-focused engineering role with strong database ownership.
- Deep expertise in PostgreSQL, particularly in AWS environments such as RDS or Aurora, including performance tuning and optimization.
- Strong hands-on experience with Snowflake, including data ingestion, query optimization, and cost/performance management.
- Advanced SQL skills, including query profiling, execution plan analysis (EXPLAIN), indexing, and schema optimization techniques.
- Proven experience building and maintaining ETL/ELT pipelines using tools such as dbt, Airflow, AWS Glue, or Python-based solutions.
- Strong experience with AWS Database Migration Service (DMS) for data synchronization and migration workflows.
- Proficiency with Git and collaborative development workflows.
- Bonus: experience with Python scripting, CDC tools (e.g., Debezium), streaming systems (Kafka, Kinesis), observability tools (Datadog, CloudWatch, Grafana), and compliance frameworks (SOC 2, TCPA, CTIA).
Benefits:
- 100% remote work with full flexibility to work from anywhere.
- Highly competitive USD salary aligned with top-tier market standards.
- Paid time off to support rest, recovery, and work-life balance.
