Responsibilities
- Reduce Azure Cosmos DB request-unit consumption by optimizing queries, indexes, partitioning, point reads, batched reads, and storage choices.
- Prioritize and deliver targeted, measurable performance fixes quickly, using larger redesigns only when smaller changes are insufficient.
- Fix hot partitions and size limits through partition-key, document, indexing-policy, and API-contract changes.
- Execute zero-downtime data migrations and repartitioning across all environments, including sovereign clouds.
- Move large, binary, unbounded, or rarely queried content to Azure Blob Storage or comparable storage when appropriate.
- Reduce database pressure through batching, request coalescing, caching, retry budgets, load shedding, and graceful degradation.
- Establish throttling budgets and caching strategies with product and partner teams.
- Own telemetry, dashboards, alerts, and measurable targets for RU usage, partition skew, availability, and latency.
- Develop AI skills and use agentic tools to identify Cosmos DB issues and accelerate engineering fixes.
- Serve as a Designated Responsible Individual in the 24/7 on-call rotation, lead data-tier incident response, mentor engineers, and represent the team with the Azure Cosmos DB product group.

- Preferred: master’s degree with 8+ years of experience, bachelor’s degree with 12+ years of experience, or equivalent experience.
- Preferred: 4+ years building or operating large-scale distributed databases, including partitioning, indexing, and query performance.
- Preferred: experience addressing throttling, hot partitions, cross-partition queries, data migrations, repartitioning, rate limits, quotas, and noisy-neighbor isolation in production.
- Preferred: deep hands-on Azure Cosmos DB knowledge covering RUs, physical partitions, hierarchical partition keys, indexing, point reads, ReadMany, change feed, consistency levels, multi-region accounts, autoscale, SDK retries, and diagnostics.
- Preferred: proficiency in C# and .NET plus experience with Azure Functions, Service Bus, Azure Cache for Redis, and API Management.
