Lead the design and evolution of highly available, scalable, secure, and operationally efficient SQL platforms that support mission-critical workloads at enterprise scale.

Provide deep technical leadership in relational database internals, including query planning, query optimization, storage engines, indexing, replication, transactions, concurrency control, and performance tuning.

Diagnose and resolve complex production issues across large SQL installations, including performance degradation, query regressions, replication issues, availability incidents, capacity constraints, and operational bottlenecks.

Build and influence sophisticated tooling, automation, and platform capabilities that improve database reliability, performance, observability, developer productivity, and operational simplicity.

Partner with application engineering teams to design, review, and optimize database architectures for complex distributed systems and high-throughput workloads.

Establish technical standards, best practices, reference architectures, and operational patterns for relational database usage across the organization.

Influence senior engineering leaders, architects, product teams, and business stakeholders by clearly communicating technical strategy, trade-offs, risks, and execution plans.

Mentor principal and senior engineers, raising the technical bar across database engineering, distributed systems, performance engineering, and production operations.

12+ years of software engineering, infrastructure engineering, or database engineering experience, with significant depth in relational database systems.
