Senior Software Engineer - LinOS Connect

Most of the food on a grocery shelf spent part of its life in a cold chain, and Lineage runs the largest one in the world. Getting food from a farm or a plant to a store without ever breaking temperature is a genuinely hard problem, and we solve it thousands of times a day. We build the software that makes it happen. Connect is Lineage's own Warehouse Management System, the system of record for warehouse inventory, orders, and customers. This position is to join the Connect engineering team that builds the integration with LinOS, our platform for automating and improving warehouse operations end to end with data science algorithms. This is software with a physical consequence. Get a release right and a facility moves more product with fewer mistakes; get it wrong and trucks wait at the dock.
