The Database Engineer role is critical to building and evolving Chess.com's database infrastructure that supports millions of daily chess games, user interactions, and a large-scale social network. This position designs and builds high-performance, scalable database systems while driving automation, tooling, and architectural improvements across Chess.com's hybrid infrastructure combining bare-metal datacenters with cloud services. The role requires deep expertise in database internals, data modeling, distributed systems, and software engineering practices to build resilient systems that deliver optimal user experiences across Chess.com's global platform.

What you'll do

Design and architect database systems optimized for Chess.com's specific workloads including real-time gaming, puzzle systems, and social graph traversal

Build internal tooling and automation to improve database deployment, migration, and operational efficiency, simplifying work streams for the broader engineering organization

Develop data pipelines and ETL processes for analytics, machine learning features, and cross-system data synchronization

Engineer multi-regional database architectures capable of handling massive volumes of chess games, user data, and social network interactions with minimal latency

Solve complex data modeling challenges including chess game storage optimization, puzzle attempt tracking, and large-scale social graph representation

Drive database platform evolution evaluating and implementing new technologies, storage engines, and architectural patterns with a bias toward continuous improvement

Build observability and performance tooling providing deep visibility into database behavior, query patterns, and capacity trends

Collaborate with product engineering teams to design optimal schemas, access patterns, and data layer integrations, ensuring the right people have the information they need

Implement infrastructure-as-code practices for database provisioning, configuration, and lifecycle management with high first-time-right quality

Participate in on-call rotation to ensure 24/7 database availability and contribute to incident post-mortems

Expert-level proficiency with MySQL (Percona) including internals, storage engine behavior, replication topologies, and performance optimization

Strong software engineering skills with proficiency in Python and/or Go for tooling, automation, and data pipeline development

Experience designing and building data pipelines using streaming or batch processing frameworks

Strong experience with Redis for caching architectures, pub/sub systems, and high-performance data structures

Advanced Linux systems knowledge with understanding of kernel behavior, I/O patterns, and hardware optimization for database workloads

Experience with distributed systems concepts including CAP theorem trade-offs, consensus protocols, and partition tolerance

Proficiency with infrastructure-as-code tools (Terraform, Ansible, Pulumi) for database infrastructure automation

Experience with monitoring and observability platforms (Datadog, Prometheus, PMM) for building database observability solutions

Strong understanding of query optimization including execution plans, index design, and workload analysis

Preferred Skills

Gaming industry experience with understanding of real-time gaming database requirements and low-latency data access patterns

Deep MySQL internals knowledge including InnoDB internals, buffer pool tuning, redo/undo logs, and MVCC behavior

Experience building database proxies or middleware (ProxySQL, Vitess, custom solutions) for connection management and query routing

MySQL replication expertise including GTID-based replication, multi-source replication, and replication lag optimization

Cloud database architecture experience with AWS (RDS, Aurora) and/or GCP (Cloud SQL, AlloyDB) for hybrid database strategies

Experience with ScyllaDB and/or Cassandra for high-throughput, low-latency distributed workloads

Knowledge of MySQL sharding and partitioning strategies for large-scale data distribution and query performance

Experience building zero-downtime migration tooling (pt-online-schema-change, gh-ost) for schema evolution at scale

Container and Kubernetes experience for database operator development and cloud-native MySQL deployments

MySQL backup and recovery expertise including Percona XtraBackup, point-in-time recovery, and disaster recovery procedures

Track record of accumulating wins — History of successful project delivery and measurable infrastructure improvements

Open source contributions to MySQL ecosystem tools, drivers, or infrastructure projects
