Position Title : MongoDB Engineering Standards Specialist
Duration : Contract until Oct 31, (possible extension)
Location : Downtown Toronto or Scarborough (2-3 days onsite)
Responsibilities :
MongoDB Engineering Standards
- Design replica set and sharded cluster topologies tailored to workload (R / W patterns, data growth, latency, multi-AZ / region).
- Schema and index design aligned with document modeling patterns (subdocuments, bucketization, extended reference, outlier pattern).
- Capacity planning (IOPS / CPU / RAM / Storage), performance tuning (indexes, query plans, connection pools, WT cache).
- Backup / restore strategy design
- Security hardening : RBAC, client certs / TLS, encryption-at-rest (KMIP / KMS), auditing, least-privilege, IP allowlists / NSGs, CIS benchmarks.
- Observability : metrics, logs, and tracing integrations (MongoDB exporters / agents).
- Release management & lifecycle : rolling upgrades, feature compatibility versions (FCV), patching cadence, maintenance windows.
