Build Kafka producers/consumers and manage schema evolution and idempotent message handling.
Create and maintain BullMQ queues/workers for jobs, retries, and DLQs.
Optimize reliability, performance, and observability (metrics/tracing/logs).
Lead development verticals and come up with database design

REQUIREMENTS

3+ years with Node.js and Express in production.
Strong foundation in database and system design — schema design, indexing, normalization, and consistency models.
Hands-on with PostgreSQL sharding/partitioning and online data migration.
Experience designing Kafka topics and consumers with idempotency and replay safety.
Proficiency with Redis/BullMQ (rate limits, retries, concurrency, DLQs).
Solid TypeScript/JavaScript and testing skills.
Experience with monitoring, profiling, and tuning (p95 latency, connection pools).
