Senior Scalability & Platform Engineer / SRE

We are hiring a senior scalability engineer to help prepare a modern microservices backend for high-concurrency production usage. This role is focused on backend performance, reliability, capacity planning, async workflow design, database scalability, and observability.

This is not a generic DevOps-only role. We are looking for someone who can reason deeply about how backend systems behave under load: database pressure, queue depth, retries, rate limits, stuck jobs, async workflows, API latency, and failure recovery.

Responsibilities

• Analyze backend architecture and identify scalability bottlenecks across APIs, services, database, cache, queues, storage, and third-party integrations.
• Design and execute load tests for high-concurrency user flows.
• Tune Postgres queries, indexes, connection pools, pagination, and transaction patterns.
• Design reliable queue/background-job systems with retries, idempotency...
