The Opportunity
Our client, a rapidly growing, venture-backed logistics and fulfillment company, is building a next-generation, custom Warehouse Management System (WMS) from the ground up — along with the full ecosystem of operational systems that surround it. This is not just a WMS: the scope includes the end-to-end operational technology stack, spanning real-time inventory control, order management, carrier and EDI integrations, 3PL connectivity, and ERP-adjacent workflows. The platform will replace the current operations stack and transform how the company manages warehouse operations at scale.
What you'll do
As a Senior Full-Stack Engineer (frontend-oriented), you will be the primary owner of the React PWA that replaces 10 warehouse floor scanner applications, as well as the admin/back-office web app. These interfaces are used by warehouse workers all day, every shift, on handheld Android scanners — the UX must be fast, reliable, and error-resistant. You will implement designs produced by the Product Designer with precision, contribute to API design and backend work, and be a full participant in every layer of the system. This is a high-craft, high-impact role where what you build is immediately visible and felt on the warehouse floor.
