About The Position

WorkOS builds tools and services for developers to help them implement authentication, identity, authorization, and overall enterprise readiness. We’re a fully distributed team with employees across North American time zones. We’re well-funded, having raised $100m in funding from top investors including Greenoaks Capital, Lachy Groom, and Lightspeed Ventures. Our fast-growing customer base includes rapidly growing SaaS companies like OpenAI, Cursor, Perplexity, Vercel, Plaid, and hundreds of others. About the Infrastructure Team The Infrastructure team ensures the WorkOS platform remains fast, reliable, and resilient at scale. We build the systems and practices that keep everything running smoothly—handling hundreds of millions of requests, minimizing downtime, and continuously improving service performance. Our team works across the stack and collaborates closely with product engineering teams. As a Database Reliability Engineer on this team, you'll bring specialized database expertise to the Infrastructure organization. You'll own the full lifecycle of database management, from design and capacity planning through performance optimization and disaster recovery, ensuring data durability and scalability as WorkOS grows. As a Database Reliability Engineer, you'll be the expert our engineering teams turn to for everything database-related. You'll work across the stack to ensure our PostgreSQL infrastructure (and related data stores) can support WorkOS's growth, from query optimization to capacity planning to incident response. You'll combine the mindset of a software engineer with deep database administration expertise to build automation, improve observability, and make our data layer self-healing wherever possible.

Requirements

5+ years of experience running PostgreSQL in production at scale, with strong knowledge of internals (WAL, MVCC, vacuum tuning, query planner, indexing, replication).
Solid software engineering skills. You write production-quality code, not just scripts. Experience with Python, Go, Ruby, or similar languages.
Experience with infrastructure-as-code and configuration management (Terraform, Ansible, Chef, or similar).
Strong SQL skills and the ability to review and optimize complex queries for high-throughput, low-latency environments.
Experience with database high-availability patterns: streaming replication, connection pooling (PgBouncer), failover automation (Patroni or similar).
Familiarity with cloud database services on AWS (RDS, Aurora, DynamoDB, ElastiCache) or equivalent platforms.
Experience with monitoring and observability tools (Datadog, Prometheus, Grafana, or similar) applied to database workloads.
Comfort with on-call responsibilities and a track record of effective incident response.
Strong written and verbal communication skills. You document your work and share context proactively.
A proactive, ownership-driven mindset. When you see something broken, you fix it. When you see a pattern of toil, you automate it.

Nice To Haves

Experience with other data stores beyond PostgreSQL (Redis, DynamoDB, ClickHouse, Elasticsearch).
Familiarity with Ruby on Rails or Django and how ORMs interact with the database layer.
Experience with database migration tooling and blue-green or zero-downtime migration strategies.
Contributions to open-source database tooling or the PostgreSQL ecosystem.
Background in security-sensitive environments, particularly around data encryption, access controls, and compliance requirements.

Responsibilities

Own the reliability, performance, and scalability of WorkOS's PostgreSQL infrastructure.
Analyze and implement best practices for our database clusters, including replication, connection pooling, high availability, and disaster recovery.
Build and maintain observability for database metrics (query performance, replication lag, connection saturation, storage growth) and ensure we meet our database SLOs.
Provide database expertise to product engineering teams through migration reviews, query optimization guidance, and schema design consultation.
Develop automation and self-service tooling that enables engineers to safely interact with databases without bottlenecking on the DBRE team.
Participate in on-call rotations and lead incident response for database-related production issues, performing root cause analysis and implementing permanent fixes.
Plan and manage database capacity, forecasting growth and ensuring our infrastructure can handle increased workloads.
Collaborate with SREs to roll out infrastructure changes to production environments, with a focus on minimizing risk to the data layer.
Document operational procedures, runbooks, and architectural decisions so learnings become repeatable actions and eventually automation.
Drive improvements to backup and recovery strategies, regularly testing and validating disaster recovery procedures.
