Our values Care about people first Strive to add value always Lead with integrity Have fun every step of the way 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 Tech Lead, you are the most critical technical hire on this project. You will own the system architecture, define the data model, set engineering standards, and lead a small team of senior engineers through a complex greenfield build. You will work directly with the Technical Project Manager and our client leadership to translate operational requirements into a robust, scalable system — and you will write production code every day alongside your technical leadership responsibilities. This is not a management role; it is a deeply technical lead role on a fast-paced, high-stakes build.
