• Triage and resolve CPU/IO/locking/replication incidents; analyze slow query logs and EXPLAIN/EXPLAIN ANALYZE plans to produce immediate mitigations and long-term fixes.
• Plan and execute zero-downtime schema changes with safe rollback paths (online DDL, gh-ost / pt-online-schema-change, pg_repack, logical replication, trigger-based backfills).
• Partner with application teams to remove N+1 queries, tune indexes, and rewrite inefficient predicates; design partitioning and retention for high-write tables.
• Design, execute, and regularly validate backup and disaster-recovery procedures.

Ownership

• Act as an expert in infrastructure design, performance, and operations across multiple systems and services.
• Promote shared ownership of infrastructure by driving documentation, tooling, and process improvements.
• Monitor and optimize system performance, ensuring reliability while protecting teams from burnout.

Leadership & Collaboration

• Build relationships with engineering teams, product managers, and cross-functional partners to ensure infrastructure supports company goals.
• Contribute to defining strategic technical direction, setting infrastructure roadmaps, and guiding prioritization.
• Advocate for best practices in reliability, security, and cost management.
• Ensure knowledge is shared within the team, reducing single points of failure.

• Experience with observability and monitoring tooling (Datadog, CloudWatch, or similar), including slow query and error log analysis.
• Ability to diagnose connectivity issues affecting database access (security groups, VPC routes/TGW, VPN, DNS).
• Scripting and automation skills (Python, Bash, or similar).
• Excellent communication and collaboration skills.

Additional skills that are a plus:

• Experience with Teleport (or similar DB proxying) and IAM DB authentication.

• Familiarity with data infrastructure (Airflow, Databricks) and messaging/streaming systems (RabbitMQ, Kafka, DynamoDB, MongoDB).
• Knowledge of network security, vulnerability management, and incident response best practices.
