Validate the customer's backup and disaster recovery strategy by defining RPO and RTO requirements, executing a timed restore drill including oplog replay, and producing a signed-off DR runbook
Stand up comprehensive observability and SLOs for the customer's MongoDB environment, covering availability, replication lag and p95 latency metrics, wire alerts to the customer's on-call systems, and author runbooks addressing top failure modes including stepdown, oplog window collapse, stuck chunk migration and disk pressure
Work collaboratively with the customer's stakeholders to communicate findings, recommendations and implementation timelines throughout all phases of the engagement
Lead best practice reviews and knowledge transfer sessions with the customer's database and engineering teams to build internal capability

Nice to have:

Background in aviation, aerospace or safety-critical industries where high availability and disaster recovery are paramount
Experience designing failure mode runbooks and incident response procedures
Familiarity with cloud-based MongoDB deployments (Atlas) alongside on-premises architectures
