Backend Engineer (Node.js)

About the role

Join our backend team to build the APIs and services powering customer-facing products across fintech, healthcare, and e-commerce clients. You'll work on systems that handle real traffic, real money, and real edge cases — and you'll have the autonomy to make the architectural calls that get them right.

What you'll do

• Design, build, and maintain REST and GraphQL APIs in Node.js / TypeScript
• Model data thoughtfully in Postgres with attention to indexing and access patterns
• Build event-driven workflows and background jobs (BullMQ, Kafka, or similar)
• Own observability — logs, metrics, traces — for the services you ship
• Write integration and end-to-end tests that catch the bugs that matter
• Participate in architecture reviews and propose improvements with a written RFC

What we're looking for

• 3+ years building production Node.js services
• Strong TypeScript and modern JavaScript fundamentals
• Production experience with Postgres (or another relational database)
• Comfort with Docker and at least one cloud (AWS, GCP, or Azure)
• Practical understanding of REST API design and HTTP semantics
• Async-friendly written communication style

Nice to have

• Experience with Redis, BullMQ, or other queue systems
• Background in distributed systems or event-driven architecture
• Familiarity with Prisma, Drizzle, or other type-safe ORMs
• Open-source contributions
