We conduct monthly financial reviews as a team so everyone has a pulse on the health of the business and publish what we are building in our weekly changelog. As a Senior Platform Engineer focused on datastores, you'll be the team's expert on PostgreSQL, OpenSearch, Kafka, and Redis. You'll work closely with our platform engineering leader, and with product engineers to shape how their features store and query data. Own the performance and reliability of PostgreSQL, OpenSearch, and Redis in production. Lead capacity planning and load testing so we know our limits before a customer's worst day finds them. Set standards for schema changes, migrations, indexing, and query patterns, and build checks that catch problems before they ship. Review data-heavy changes from product teams and teach the patterns behind your feedback. Partner on multi-region data replication and recovery with the Infrastructure side of Platform. We care about impact, ownership, and technical judgement. Degrees and big-name logos are not required. 5+ years building and running production systems, with significant time on datastore performance and reliability. Experience supporting multi-tenant systems at scale, including tenant isolation,



noisy-neighbour protection, and keeping one customer's traffic spike from degrading service for everyone else. Deep knowledge of PostgreSQL internals: locking, MVCC, query plans, indexing, vacuum, and connection pooling. Experience with capacity planning and load testing for web services. You write production-grade software, and you're comfortable working in an application codebase, not only in the database. Experience with Rails, ActiveRecord, and Sidekiq at scale. Experience with cross-region replication and database failover. Established a load testing baseline and capacity plan, so we know our limits before customers find them. Ruby on Rails, PostgreSQL, OpenSearch, Redis, Sidekiq, AWS Lambda, ECS, Kafka, DynamoDB Frontend: Infrastructure: AWS, OpenTofu/Terraform (IaC), Datadog We're building something category-defining and want teammates who crave ownership, love solving hard problems, and thrive in a high-bar, high-impact environment. Competitive compensation and early equity in a quick-growing, venture-backed company. Comprehensive medical, dental, and vision coverage. 3 weeks of vacation, plus unlimited sick and mental health days, and a company-wide end-of-year shutdown to recharge. $500 stipend for home office setup. Unlimited token usage and access to AI tools. As we build out the team, we may use AI to support parts of our interview process, like reviewing assessments, but it's a tool that helps our people, not a substitute for their judgement.
