Description
Build the routing engine behind every Amazon delivery. Planet-scale pathfinding that runs a trillion route calculations a day at microsecond latency, shaping how millions of packages reach customers safely and on time, every day.

We're seeking a Software Development Manager to lead the Transit Intelligence team in Bellevue. The team owns the road network and routing foundation for Amazon Last Mile: road network construction and vending, pathfinding and transit time estimation. These systems compute how long it takes to get from A to B and what the safest path is, at two extremes of scale at once. Navigation needs answers in milliseconds in real time; route planning needs the full origin-by-destination product, adding up to over 1.2 trillion pathfinding calculations across the fleet each day.

The SDM will lead a team of software engineers building the algorithms and infrastructure behind this scale: effective precomputation, succinct graph representation...
