Toast is driven by building the restaurant platform that helps restaurants adapt, take control, and get back to what they do best: building the businesses they love.
SEAR at Toast focuses on two things: actionable intelligence collection, analysis, and delivery to engineers, and hunting the adversaries who would damage and defraud Toast, its customers, and its partners. We bake security into every layer of our products, from the first sprinkle of an idea to the final serving of a fully‑baked solution. Our team is tasked with searching out and degrading the operations of persistent, motivated attackers.
Like master chefs, we blend cutting‑edge technology with strategic thinking, implementing bespoke and industry‑standard solutions for intelligence processing at scale. By joining SEAR, you'll be part of the kitchen crew that keeps our customers' trust from going stale. You'll tackle complex challenges that have real‑world impact, helping to serve up a safer, more secure digital experience for businesses that count on Toast every day. It's not just about pattern‑matching – it's about crafting a recipe for digital trust that keeps our customers coming back for more.
