Type: Full-time (India – Hyderabad) Experience: 1–3 years or proof of 2–3 production deployments About the role : Own backend services built with Django + DRF that are secure, scalable, and observable . You’ll design clean REST APIs, optimize PostgreSQL , use Redis for smart caching, and ship with Docker → Gunicorn → Nginx . Experience with microservices , SSO , and JWT is essential. Responsibilities: Design, build, and document REST APIs (versioning, pagination, filtering, rate-limits, idempotency). Model data and optimize queries in PostgreSQL (indexes, migrations, query plans). Implement Redis caching strategies (per-view, low-level cache, keys & TTLs, cache-aside/write-through). Set up OpenAPI docs with Swagger UI / ReDoc ; keep docs in sync with code. Productionize services using Docker , Gunicorn , Nginx ; automate deploys. Architect and maintain microservices ; handle service discovery, contracts, and resilience. Implement AuthN/AuthZ : JWT (access/refresh/rotation), SSO (OIDC/SAML) for first-party & third-party clients. Build for scale & reliability : background jobs, retries, timeouts, circuit breakers, health checks. Add metrics, logs, and traces; fix performance bottlenecks and improve latency. Collaborate via Git/GitHub (PRs, reviews, trunk-based or GitFlow). Must-Have Skills : Django 4+/DRF deep knowledge (serializers, viewsets, permissions, throttling, signals). PostgreSQL mastery: schema design, indexing strategies, EXPLAIN/ANALYZE, locking basics. Redis & caching patterns; session/token blacklisting; rate-limiting. Auth: JWT (short-lived tokens, refresh flow, rotation) and SSO (OIDC/SAML) fundamentals. API Docs: OpenAPI 3 with drf-spectacular or drf-yasg ; Swagger/Redoc . Deployments: Docker & Docker Compose, Gunicorn + Nginx production setup. Microservices concepts: API contracts, backward compatibility, message vs request/response, resiliency. Git/GitHub proficiency (branching, code reviews, Actions/CI basics). Track record of 2–3 real deployments (links or proof). Good to Have : FastAPI (for high-perf micro-endpoints) CI/CD: GitHub Actions; Jenkins exposure Task queues: Celery / RQ; scheduled jobs Observability: Sentry, Prometheus/Grafana, ELK/OpenSearch Security: OWASP, Secrets management, CORS/CSRF best practices
