■ Position Title : Software Engineer(Supply Chain Systems)
■ General Responsibilities :
1. WMS Development: Design and develop core Warehouse Management System (WMS) features, including inventory tracking, order fulfillment, warehouse operations, and internal logistics workflows used daily across U.S. logistics centers.
2. Event-Driven Data Processing: Architect and implement event-driven pipelines to reliably process high-volume order, inventory, and operational data across distributed systems.
3. External Integration & Data Synchronization: Integrate with external sales channels and platforms (e.g., Shopify) using webhooks, APIs, and ETL pipelines while ensuring reliable, real-time data synchronization across systems.
4. Supply Chain Data Architecture: Design and structure the foundational data models and workflows required to support end-to-end supply chain and import/export operations.
5. Cross-Team Collaboration: Collaborate with U.S. and Korean teams to identify operational challenges, coordinate technical solutions, and improve internal processes.
■ Qualifications
- 5+ years of professional software development experience using TypeScript.
- Strong backend/server-side development experience with Node.js.
- Experience with event-driven architectures and message queue systems (e.g., Inngest, Redis, Pub/Sub, BullMQ).
- Experience building data synchronization pipelines using webhooks, APIs, and ETL processes.
- Experience integrating with external platforms at scale, including handling API limitations such as ratelimits, quotas, retries, and authentication flows while maintaining data consistency across distributed systems.
Non-Negotiable Technical Stack
- TypeScript / Node.js (5+ Years): Must be a core backend/systems engineer, not a front-end developer who occasionally writes a basic Node API.
- Event-Driven Architecture & Message Queues: Deep, hands-on production experience with Inngest,
- Redis, BullMQ, Kafka, or RabbitMQ. They must understand asynchronous distributed systems.
- Data Pipelines: Proven success building robust Webhook, API, and ETL data synchronization pipelines.
- Integrations at Scale (Data Integrity): Experience handling heavy external system connections— specifically dealing with complex retry logic, rate limits, authentication, and maintaining strict data idempotency (preventing database race conditions or corrupted warehouse states).
■ Preferred Qualifications
- Experience developing Warehouse Management Systems (WMS) or fulfillment/logistics platforms.
- Experience developing Shopify apps or integrating with e-commerce platforms.
- Experience with PostgreSQL and database optimization for high-volume workloads.
- Experience with serverless backend platforms (e.g., Cloud Functions, Firebase, Supabase, Hasura).
- Strong communication and collaboration skills in cross-functional team environments.
- Ability to read and write technical documentation in English and/or Korean.
