TLDR

Optimize high-volume PostgreSQL OLTP databases and strengthen production readiness through testing, monitoring, recovery, and incident response.

As the Senior Database Architect, you will provide technical leadership for the design, performance, scalability, and reliability of our production database environments. You will partner closely with Software Engineers, Platform Engineers, Product Managers, and other technical stakeholders to evaluate existing database architectures, identify opportunities for improvement, and establish database engineering best practices across our products.

A primary responsibility of this role is to optimize and maintain our high-volume OLTP databases, with a strong emphasis on PostgreSQL. You will assess existing environments, identify performance and scalability bottlenecks, and drive improvements across schema design, indexing, partitioning, query performance, replication, and database configuration. You will also provide guidance to engineering teams as they design and implement new database-backed features.

You will help strengthen production readiness by establishing and improving practices around performance testing, release validation, monitoring, alerting, backup and recovery, high availability, access controls, and incident response. You will play a key role in troubleshooting complex production issues, performing root-cause analysis, and ensuring database changes are thoroughly tested before deployment.

This role requires someone who can combine deep hands-on database expertise with strong technical judgment and communication skills and someone who can assess an existing environment, make practical recommendations, and partner with engineering teams to implement scalable, reliable solutions.
