Software Engineer II, Earnings

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 a rapidly growing company that's revolutionizing how the restaurant industry does business by pairing technology with an extraordinary commitment to customer success. We help restaurants streamline operations, increase revenue, and deliver amazing guest experiences through our platform that combines restaurant point of sale, team management, guest-facing technology, and award-winning customer support. Join us as we empower the restaurant community to delight guests, do what they love, and thrive. We're looking for an engineer to help build and scale Toast's earnings platform — systems that calculate tips and employee earnings for restaurant locations across Toast's network. You'll work on highly visible, mission-critical infrastructure that powers Tips Manager, one of Toast's growing products, while laying the groundwork for a broader earnings calculation platform that will determine paychecks for employees everywhere Toast operates. In this role, you'll gain hands-on experience with event-driven systems built on Kotlin, gRPC, Apache Pulsar, and DynamoDB. We're building a new source of truth for employee earnings — from real-time tip pooling and redistribution to wage calculation and earnings retrieval — and we care deeply about getting the math right: our systems directly influence what employees take home. If you're excited to build calculation infrastructure where correctness and scale matter in equal measure, and where the work has a real impact on product revenue and employee livelihoods, we'd love to hear from you. About this roll*: As a Software Engineer on our team, you will: • Help shape our tip and earnings calculation platform — building the systems that determine how restaurant employees are paid, starting with Tips Manager and expanding toward a full earnings source of truth. • Build, run, and improve core backend services alongside a collaborative, supportive team. • Be a part of the organization with a strong focus on engineering culture and full end-to-end ownership. • Participate across the full development lifecycle — design, estimation, implementation, testing, debugging, and deployment — while learning and applying best practices for building correct, reliable calculation systems at scale. • Ship code that directly impacts Tips Manager revenue and the accuracy of earnings for restaurant employees across Toast's network. • Partner with product and design to influence what we build and how we build it. • Participate in thoughtful code reviews, both giving and receiving feedback. Do you have the right ingredients*? • Experience with one or more object-oriented programming languages (such as Java, Kotlin, or similar). • An appreciation for precision and correctness — when the output drives someone's paycheck, getting the calculation right matters. • Willingness to monitor, troubleshoot, and improve system performance through logging and metrics. • Ability and motivation to learn quickly and apply knowledge to solve real problems. • A hunger to take on challenging problems where correctness and scale go hand in hand. Above all, we’re looking for a strong engineer with solid fundamentals. This role is for a current vacancy. Leverage cutting edge AI tools to enhance your development workflow, improve velocity, and help pioneer new approaches to building - contributing to a culture of innovation and productivity across the team.
