The posting

Now, more than ever, the Toast team is committed to our customers. We’re taking steps to help restaurants navigate these unprecedented times with technology, resources, and community. Our focus is on building the restaurant platform that helps restaurants adapt, take control, and get back to what they do best: building the businesses they love. And because our technology is purpose-built for restaurants, by restaurant people, restaurants can trust that we’ll deliver on their needs for today while investing in experiences that will power their restaurant in the future.

Are you ready for a change?

We are looking for an experienced software engineer to play a critical role in further scaling and developing Toast’s cloud platform and infrastructure. Toast’s platform processes billions of requests per day from hundreds of internal services and hundreds of thousands of mobile devices; these numbers grow exponentially year over year as we add new restaurants and capabilities to the platform. Our team is responsible for developing secure, observable, highly available, large-scale shared services and infrastructure.

About this roll* (Responsibilities)

  • Architect, design, and deliver ultra-reliable, high-performance services and infrastructure used by millions
  • Uncover and resolve performance bottlenecks across infrastructure, databases, and APIs
  • Define and enable adherence to engineering best practices, coding standards, and architectural guidelines
  • Collaborate closely with the Product team to influence features, technical direction, and long-term product vision

Do you have the right ingredients?

  • Hands-on experience building and operating complex, mission-critical, large-scale distributed systems in the Cloud
  • Expertise in asynchronous messaging, event-driven architecture, APIs, and integration patterns
  • Track record of delivering clean, maintainable, and resilient code that stands the test of time
  • Proficiency in Java or Kotlin preferred (experience in other modern programming languages also valued)
  • Exceptional communication and collaboration skills, with demonstrated ability to align and inspire cross-functional teams
  • A demonstrated record of mentoring junior team members and enhancing the team's effectiveness

Tech Stack

Our team builds and operates on a modern, cloud-native stack with heavy use of AWS, developing services and shared libraries in Kotlin and Go backed by PostgreSQL and DynamoDB. Infrastructure is provisioned and managed with Terraform. We oversee Toast’s sharded PostgreSQL databases, own and drive the organization’s use of Apache Pulsar to enable event-driven architecture at scale, and provide developers with tools and services to easily schedule recurring jobs. Our systems also power customer engagement, integrating with SMS and email providers to reliably deliver millions of messages per day.

We embrace AI-driven software development at Toast across the lifecycle from design and implementation to testing and production monitoring.

How Toast Uses AI in its Hiring Process

Throughout the hiring process, our goal is to get to know you. We use AI tools to support our recruiters and interviewers with tasks like note-taking, summarization, and documentation of interviews to ensure they can be fully focused on your conversation. All hiring decisions are made by people. We ask that you complete interviews and assessments on your own, without real-time AI tools, recording, or transcription bots, unless we tell you otherwise in advance.

Our Approach to Hybrid Working

We embrace a hybrid work model that fosters in-person collaboration while valuing individual needs. Our goal is to build a strong culture of connection as we work together to empower the hospitality community, regardless of location.

People Are the Secret Ingredient in Our Recipe for Success

At Toast, our employees are our secret ingredient—when they thrive, we thrive. The restaurant industry brings together people with a wide range of backgrounds, experiences, and perspectives, and we value that same breadth at Toast. We strive to build a culture grounded in authenticity, respect, and humility, where every Toaster has a real opportunity to grow, contribute, and do their best work—raising the bar in delivering exceptional experiences for our customers and each other.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
