Full Stack Engineer

At Guac, we’re solving grocery food waste with predictive ML. We predict exactly how much of each product will sell, helping grocery retailers order/produce the perfect amount of inventory.

The grocery industry is enormous (it accounts for 4% of GDP) — and grocery food waste is a huge cost to grocers’ bottom lines, but also to our planet.

Today, we’re working with major supermarket chains in the US (you’ve probably shopped at some of them before), and we’ve scaled to 7-figures in ARR. We’re also backed by leading investors such as Y Combinator, 1984 Ventures, Collaborative Fund, and angels from Instacart and Citadel Securities.

We’ve brought together an exceptional team from Palantir, BCG, Oxford, Cambridge, and MIT to solve intellectually challenging problems and tackle food insecurity & waste with technology.

We’re looking for talented engineers in NYC to join our mission.
