📋 Description

• Own the services that keep Strata's customers unblocked — support, exception-handling, and remediation backend. • Build backend for Expert-in-the-Loop (HITL) queue — APIs to surface low-confidence documents, capture decisions, and resume workflows. • Design and implement scalable APIs in NestJS/TypeScript and/or FastAPI/Python using Domain-Driven Design (DDD). • Implement event-driven workflows over SQS with DLQ patterns, exponential backoff, and idempotent processing. • Model and optimize PostgreSQL schemas (Aurora) with migrations, indexing, and strict tenant isolation. • Write runbooks for services owned and participate in on-call rotation alongside SRE. • Collaborate with SRE on SLOs, dashboards, and incident response; with Customer Success on support needs.

🎯 Requirements

• 6+ years backend engineering in production, shipping and operating real services (not just prototypes). • Strong in at least one, comfortable in both: Node.js/TypeScript (NestJS or equivalent) and Python (FastAPI). • REST API design, validation, auth, and clean error handling. • Deep PostgreSQL — schema design, migrations, query optimization, indexing, and multi-tenant isolation / row-level security. • Event-driven & async patterns — message queues (SQS, Kafka or equivalent), DLQs, retries, idempotency, and designing for partial failure. • AWS proficiency — Lambda, ECS/Fargate, S3, SQS, API Gateway, RDS/Aurora. • Reliability mindset — you design for SLOs, instrument for observability (structured logs/metrics/traces, correlation IDs), and have carried a pager. • Testing discipline — unit + integration + e2e testing (pytest/Jest, moto/localstack, SuperTest), and CI/CD experience. • Security awareness — authn/authz, rate limiting, input validation, secrets management, and audit logging. • English proficiency : B2+ required (C1 preferred).
