This role leads the evolution of a mission-critical operational platform used to manage warehouse workflows, shipping processes, inventory tracking, and internal operational tooling.

The current system grew quickly to support business growth and now needs a modern architecture that can scale. Much of the logic currently lives in Google AppScript, AppSheets, and Sheets-based workflows, and is being migrated to a Node.js API and PostgreSQL data platform.

You will take ownership of the backend systems that power day-to-day warehouse operations, such as building robust APIs, designing workflow logic, and creating systems that improve throughput, visibility, and operational reliability.

This is a high-impact, hands-on engineering role where the software you ship directly affects how efficiently products move through the warehouse and how internal teams manage operations.

Sample Projects:

Backend Modernization & Service Migration - Core business logic currently runs in a legacy scripting environment with reliability and observability limitations.

Data Model & Persistence Upgrades - Operational data currently lives in lightweight tooling not designed for scale.

Operational Workflow Rebuilds - Several high-volume workflows require redesign to support increased complexity and transaction scale.

End-to-End Visibility Enhancements - There is a clear opportunity to extend system visibility across the physical fulfillment chain.
