Responsibilities
Lead the Cosmos DB Migration
Migration Strategy: Design and execute zero-downtime migration paths from legacy databases (PostgreSQL, MongoDB, or others) to Cosmos DB
Architectural Redesign: Lead the "lift and shift" vs. "refactor" decision-making process. You will redesign relational or legacy NoSQL schemas into optimized, partitioned Cosmos DB models
Tooling & Automation: Build or implement data migration pipelines (using Azure Data Factory, Change Data Capture, or custom Spark jobs) to ensure data integrity and consistency during the transition
Validation & Cutover: Establish rigorous testing frameworks to validate data parity, latency benchmarks, and failover reliability before final cutover
Cosmos DB Operations & Scale
RU Optimization: Post-migration, you will be responsible for tuning Request Units (RUs) and indexing policies to ensure the new system is more cost-effective and performant than the old
Partitioning Mastery: Implement complex partitioning strategies (including hierarchical partitioning) to eliminate hot spots in our most high-traffic collections
Global Distribution: Configure multi-region write capabilities to ensure Perplexity users have sub-10ms latency regardless of their location
Qualification
Required
8+ years of software engineering experience, with a proven track record of leading large-scale database migrations
Cosmos DB Specialist: Prior experience operating cosmos DB at scale
Migration Experience: You have successfully moved production workloads with zero or near-zero downtime at a previous high-growth company
Systems Expert: Strong understanding of distributed systems, CAP theorem, and how to manage data consistency across a migration boundary (e.g., dual-writing, shadow reads)
Backend Proficiency: Strong coding skills in Python, Go, or TypeScript, with the ability to build custom migration scripts and service-level abstractions
