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. ■
