Korea-Based Node.js Backend Developer

I’m growing a customer-facing web product and need a backend engineer here in Korea who lives and breathes Node.js. Your main responsibility will be owning our REST API layer: designing new endpoints, shaping data models, and keeping latency low even as traffic climbs. What you’ll do day-to-day • Plan and implement new micro-services in modern Node.js (Express/Nest or comparable frameworks). • Model clean, scalable database schemas and write the queries that power them. Whether we end up on PostgreSQL, MySQL, or MongoDB, you’ll guide the decision with real-world arguments. • Integrate third-party services, payment gateways, and internal tools through well-structured interfaces. • Write thorough unit and integration tests, automate builds in a CI/CD pipeline, and monitor production performance. Collaboration & workflow We’re a small product team operating on Korean business hours, so quick Slack/Zoom feedback loops and readable Git commits matter more to us than heavyweight processes. You’ll work directly with me (product) and our React front-end dev to ship weekly iterations. What I’m looking for • Deep Node.js expertise and confidence in building secure, versioned REST APIs. • Solid grasp of relational and NoSQL schema design. • Practical experience with Docker, GitHub Actions (or similar), and cloud deployment on AWS, GCP, or Azure. • Comfortable communicating in either Korean or English; you must already be based in Korea for timezone overlap and occasional on-site workshops in Seoul. If you’re excited to architect a backend from the ground up, keep it humming in production, and have a real voice in tech choices, let’s talk.
