Associate Architect Backend; NestJS​/TypeScript​/Microservices

We at Confiz are hiring an Principal Backend Engineer with strong expertise in backend technologies, system architecture, and performance optimization. Join our team to design and build scalable, secure, and high-performing backend systems that power exceptional digital experiences for global enterprises..

• Own microservices in NestJS (Type Script): define module boundaries, version APIs, and ship resilient, well-tested services.
• Design internal communication: implement REST/gRPC/event-driven patterns (e.g., request/response, pub/sub), handle retries, timeouts, backoff, and circuit breakers.
• Implement secure JWT auth: access/refresh life cycles, rotation, audience/issuer validation, revocation/blacklisting, and token storage best practices.
• Deliver payment integrations: integrate with gateways (e.g., Stripe/Adyen/Braintree), implement idempotent operations, handle captures/refunds/disputes, and reconcile via signed webhooks.
• Build and consume webhooks: define payload contracts, verify signatures/HMAC, ensure idempotency, and implement robust retry and DLQ strategies.
• Enable real-time features with Web Sockets: use NestJS Gateways/Socket.
  
  IO or ws for presence, notifications, and fan‑out at scale; secure and rate‑limit connections.
• Use Redis/Valkey effectively: design cache keys/TTLs, apply cache‑aside/write‑through, implement distributed locks, queues/streams, pub/sub, and mitigate hot keys.
• Containerize and run locally: craft efficient multi‑stage Docker builds, add health checks, and orchestrate multi‑service dev stacks with docker‑compose.
• Quality & reliability: write unit/integration/e2e tests (Jest/Supertest), add schema validation (class-validator/OpenAPI), and instrument with logs/metrics/traces.
• Collaborate across teams: review PRs, write concise design docs, and partner with product, frontend, and data to deliver measurable outcomes.

• 5+ years building backend systems; 5+ years NestJS + Type Script in production.
• Strong Docker and docker‑compose skills (multi‑stage builds, image slimming, health checks).
• Solid microservice design: domain boundaries, API versioning, idempotency, saga/choreography, and eventual consistency (outbox/inbox).
• Hands‑on JWT implementation in distributed systems.
• Demonstrated payment experience (idempotency keys, reconciliation jobs) and webhooks (HMAC/signatures, replay protection, retries).
• Built and scaled Web Sockets features in production.
• Proficiency with Redis/Valkey for caching and real‑time patterns; strong SQL fundamentals (Postgre
  
  SQL/MySQL) and practical ORM experience (TypeORM/Prisma).
• Testing mindset with meaningful coverage and CI checks; working knowledge of security best practices (OWASP, secrets management, least privilege).
• Comfortable with telemetry (structured logs, metrics, tracing) and on‑call ownership.
• Kong Gateway (or similar API gateway) for routing, auth, rate limiting, and observability.
• Kubernetes/Helm; service meshes (Istio/Linkerd).
• Event platforms (NATS/Kafka/Rabbit
  
  MQ) and streaming patterns.
• Graph
  
  QL (Apollo/NestJS) including subscriptions.
