Your Role

- The Online Storage team is a foundational infrastructure team within Zip's Engineering organization. We own and operate the core storage, search, and permissions infrastructure that powers everything Zip's product teams build—spanning relational databases (Aurora RDS), caching layers (Elasticache, MemoryDB), DynamoDB, S3, OpenSearch, and the permissions framework that ensures every user sees exactly the data they're authorized to see.

- As a Senior Software Engineer and Site Tech Lead, you will be the senior technical voice in Toronto for both the Storage and Search domains. You will partner closely with Online Storage leadership in San Francisco, drive technical execution across the Toronto cohort, and play a hands-on role in re-architecting foundational systems to support Zip's global expansion. Your technical leadership will raise the bar for the engineers around you while directly shipping work that enables Zip to serve enterprise customers across multiple continents.

You Will

- Serve as the site tech lead for the Online Storage team in Toronto, providing technical direction and day-to-day guidance to engineers across the Storage and Search domains.

- Evolve Zip's search infrastructure—including OpenSearch, search APIs, and Global Search—from a fragmented set of systems toward a unified, intelligent, and measurable search platform.

- Evolve Zip's core storage stack—Aurora RDS, Elasticache, MemoryDB, DynamoDB, and S3—to support multi-region, multi-cell architectures as Zip expands across the US and EU.

- Drive complete cell isolation: eliminate cross-cell database and search connections so that a failure in one cell cannot cascade to another.

- Mature disaster recovery posture across every stateful system, validating RTO and RPO targets through practiced fire drills rather than aspirational documentation.

- Improve the performance and debuggability of Zip's data layer, giving engineers across the org clear tooling to diagnose and resolve regressions quickly.

- Collaborate with the SF-based Online
