Description At Amazon we deliver billions of packages every year, in addition to the many packages delivered by 3rd party carriers like UPS. Our Last Mile organization is responsible for the customer experience of receiving the delivery, and by taking ownership of that we can innovate in that space: Same Day delivery, delivery into your garage or car, and delivery by robot, to name a few. We can continue to surprise & delight customers by bringing their packages to the place they are most convenient and expected, on time, and with the lowest delivery cost to us. The Channel Allocation & Cycle Planning team plans which packages will be dispatched earlier vs later, and which by alternate methods such as robots, walkers, bikes, motorbikes, or stores to pick them up. We can reduce cost by sending a load of packages to a remote distribution point and having delivery routes leave from there. Our systems make the best decisions on how each package in our network is delivered, complying with traffic limitations (no trucks in a zone), size restrictions, and grouping packages together for efficiency. We are looking for a Software Development Engineer who loves solving hard problems in a collaborative environment, has high standards for quality and maintainability, and is looking to grow into a space where they can have high impact on customers. You will work with other engineers on our team and in adjacent teams, as well as with research scientists, senior engineers, and product managers, to develop software to automatically create the best package plans, which are used all over the globe, multiple times, every day. Our team is dedicated to diversity & inclusion.
