MongoDB Architect / Developer
Exp:8+ Years
Bangalore, Hybrid
Key Responsibilities
Legacy Data Migration — DART Onboarding (10%)
Your responsibilities:
- Design the MongoDB ingestion layer — bulk-write strategies, upsert logic (idempotent re-processing), write-concern tuning for batch loads, and temporary staging collections for validation before promoting to production.
- Build aggregation-based data-quality checks — validate that DART-sourced documents meet JSON Schema rules
- Implement a dead-letter collection for records that fail validation or API enrichment — with metadata capturing failure reason, retry count, and source XML reference for manual remediation.
- Optimize bulk-load performance — tune batch sizes, ordered vs. unordered inserts, index builds (background vs. foreground), and temporary index suppression during large migrations to maximize throughput.
- Track lineage — maintain full audit trail from DART Oracle source → S3 raw XML → enriched JSON → MongoDB document, enabling traceability for compliance and data-quality investigations.
Schema Design, Data Modelling and implementation (40%)
MongoDB Atlas Administration & Operations (5%)
Indexing & Query Optimization (5%)

- 3+ years designing schemas for complex, deeply nested document structures (not simple flat CRUD collections).
