Senior Software Engineer, Orders Pricing

Toast creates technology to help restaurants and local businesses succeed in a digital world, helping business owners operate, increase sales, engage customers, and keep employees happy. 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. We are looking for a Senior Software Engineer to join the Orders Pricing team.

Orders Pricing team owns how every order is priced — the rules, discounts, taxes, and service charges that determine what a guest pays. Our pricing engine has to be exactly right, every time, across an immense scale of traffic and every surface an order touches, from the cloud to the point of sale. The pricing engine is a critical part of the company strategy as we expand into new verticals, encountering new complexities and pricing rules.

Why this team? Correctness at Scale: Pricing has to be exactly right on every order, every time. Getting it wrong costs restaurants and guests real money — accuracy is non-negotiable.

Hard Problems: Discounts, taxes, and service charges stack into complex rules — we turn that complexity into a fast, reliable engine. Leadership and Ownership: You’ll drive significant projects end-to-end and help grow the engineers around you.
