Software Engineer II

Responsibilities:
Build, ship, and operate backend services at scale for ZoomInfo's flagship products.
You'll work mostly in Node.js/TypeScript (NestJS preferred), design APIs, optimize data access on MongoDB/Redis, and deploy to the cloud (GCP preferred or AWS) with a focus on reliability, performance, and security.
Design and implement backend services and REST/GraphQL APIs in Node.js/TypeScript (NestJS preferred).
Own features end-to-end: design, coding, tests, code reviews, docs, and production rollout.
Model data and optimize queries in MongoDB; use Redis for caching and throughput.
Containerize and deploy via Docker/Kubernetes; automate with CI/CD.
Monitor and troubleshoot using logs, metrics, and traces; improve latency and reliability.
Collaborate with Product/Engineering to break down work, estimate, and deliver on time.
Participate in on-call rotations and post-incident reviews; contribute to runbooks.
Requirements:
2+ years of software engineering experience with building backend services in Node.js/TypeScript.
Hands-on with NestJS/Express/Fastify and strong API fundamentals (versioning, pagination, idempotency, and auth).
Practical experience with MongoDB (schema design, indexes) and Redis (caching patterns, TTL/evictions).
Cloud experience on GCP (preferred) or AWS; Docker; basic Kubernetes; CI/CD (GitHub Actions/Jenkins, etc.).
Testing skills with Jest/Playwright/Cypress; solid debugging in production.
Working knowledge of observability (logs/metrics/traces) and basic SLO concepts.
Good communication and collaboration; bias for clean, secure, well-documented code.
Nice to have:
Kafka or Pub/Sub; feature flags and canary/blue-green deployments.
Performance profiling, load testing, and cost-aware design.
