Top SchoolJason Falk is a senior engineering manager based in New York with 8 years of focused experience leading feed infrastructure and developer tooling at Nextdoor and prior leadership roles across startups and large retailers.

Jason has moved between IC and leadership roles—VP engineering to lead backend to manager—bringing product-driven engineering discipline to fast-paced environments like Jetblack/Walmart, Goldbelly, and Arrivalist.
