Senior/ Staff Frontend Engineer, Picnic - New York City

Who We Are
Picnic is reinventing lunch at work. We partner with top local restaurants and batch hundreds of orders at a time to deliver high-quality, individually packaged meals—without fees or tips. The result is a seamless, affordable, and joyful experience for employees, and a more sustainable model for restaurants.
We recently launched, and early signals have been exceptionally strong. Picnic has been adopted organically by companies across a wide range of industries, with customers discovering and advocating for the product before any marketing. Since launch, we’ve grown incredibly fast and are now entering the 10 → 100 scale phase as we expand across major North American markets.
Picnic owns the full stack that powers workplace food delivery: kitchens, courier operations, routing and batching systems, operations tooling, and client applications. This vertical ownership allows us to tightly integrate software, logistics, and operations to deliver reliable, cost-efficient service at scale.
