About the role
- Operated Zello's MySQL and MongoDB clusters to documented availability targets, with automated backups, regularly tested restores, and failover the on-call team trusts under real incident pressure.
- Cut latency or capacity cost on at least one critical database workload through measurable performance work - index strategy, query tuning, schema changes, or sharding.
- Extended our Observability coverage so incidents are diagnosed in minutes rather than hours, with dashboards and alerts the team actually uses.
Responsibilities
- Design, deploy, and operate highly available MySQL and MongoDB clusters across our cloud environments
- Participate in the Platform on-call rotation, lead incident response for data-tier issues, and write postmortems that drive durable change.
- building agents, automation, and developer-enablement tooling that scale the team's reliability work
- replication, sharding, backups, point-in-time recovery, and failover drills you've actually run, not just designed on paper.
- Design, deploy, and operate highly available MySQL and MongoDB clusters across our cloud environments; replication, sharding, backups, point-in-time recovery, upgrades, and disaster recovery.
Requirements

Nice to have
- You communicate clearly under pressure and after the fact.
- You bring an opinion on managed vs. self-managed databases, and can defend the trade-off based on availability, cost, and operational burden.
- 7+ years in SRE, DevOps, platform, infrastructure, or database reliability roles, with at least 3 years owning production databases.
- BSc in Computer Science or equivalent practical experience.
- ScyllaDB/Cassandra or Elasticsearch experience is a plus
- You've shipped meaningful work on at least two of bare metal Linux, containerized workloads (Docker, Kubernetes, or similar), and a major cloud (GCP preferred
- AWS or Azure equivalent is fine).
