  • 5–8 years of software engineering experience, with a B.S. in Computer Science or equivalent.

  • 3+ years building backend services in Node.js/TypeScript

  • Hands-on with NestJS/Express/Fastify, and strong API fundamentals (versioning, pagination, idempotency, 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.)

  • Working knowledge of observability (logs/metrics/traces) and basic SLO concepts

  • Strong interpersonal skills, with the ability to collaborate effectively across teams.

  • Demonstrated critical thinking, problem-solving, and troubleshooting abilities.

  • A sense of ownership, growth mindset, and intellectual curiosity.

    • Nice to have

  • Experience with Confluent Cloud or similar data streaming platforms is a plus.
