• Own the day-to-day administration, support, and scheduled release of the Microsoft SQL Server environment. • Install, configure, upgrade, and patch SQL Server instances across production, testing, and development environments. • Monitor database health, capacity, and performance; proactively tune queries, indexes, and configurations. • Implement and maintain backup, recovery, and high-availability strategies. • Administer database security, access controls, and user management. • Serve as the point of contact for incoming database requests from internal teams. • Execute ad-hoc queries against production and non-production databases. • Plan and execute recurring production data releases across multiple product lines and database servers. • Collaborate with development, infrastructure, and operations teams to resolve database issues and support a smooth end-user experience.

• Operate and evolve multi-region CockroachDB clusters and PostgreSQL instances across production, staging, and development. • Investigate contention, serialization retries (SQLSTATE 40001), and range hotspots in the transaction paths behind bets, wagers, settlements, and payouts. • Diagnose leaseholder placement, monotonic-key write pressure, and cross-region latency that turn one query into several network round trips. • Trace a slow query to its execution plan, the plan to optimizer behavior, and the behavior to the schema or application call path that caused it. • Catch plan regressions after statistics changes, schema changes, data growth, or releases, then turn the fix into a safer rollout pattern. • Assess schema-change and backfill risk before it reaches large tables: lock behavior, retry pressure, capacity impact, and rollback path. • Plan capacity, scaling events, and version upgrades that customers don't feel. • Build database observability with Prometheus, Grafana, Mimir, Loki, and Snowflake: dashboards backed by real queries, alerting on leading indicators, and SLO tracking. • Connect database symptoms to application behavior and business events so alerts point at causes. • Join the on-call rota for the data layer, lead incident analysis when the database is part of the failure, and drive blameless postmortems toward durable fixes. • Instrument the system to surface degradation before it becomes an incident. • Build Go and Python tools that make incidents easier to understand: log collectors, explain-plan analyzers, migration checks, capacity models, and runbook generators. • Automate provisioning, configuration, backup, and recovery with Terraform and other infrastructure-as-code tools. • Work with platform engineering on CI/CD, deployment safety, and change management for database-touching services. • Use Claude Code, Codex, and similar harnesses in daily work to investigate incidents, generate probes, draft runbooks, and write tooling. • Keep the harness grounded in logs, traces, metrics, and source code, and verify its output against production facts before you ship it. • Implement and audit access controls, authentication, authorization, and encryption in transit and at rest. • Support data-protection, audit-logging, and retention requirements for a regulated gaming platform. • Build a database center of excellence: documentation, standards, and reusable patterns that other teams build against. • Mentor engineers on database fundamentals, distributed-systems behavior, and operational discipline. • Read CockroachDB and PostgreSQL internals when a problem needs a code-level answer, and bring what you learn back to the team.
