Bready* to make a change?

We are looking for a Senior Software Engineer to play a meaningful role on the payments team responsible for processing payments on behalf of our restaurants and ensuring that restaurants are paid in a timely manner. Our payments system is built as a set of Java microservices deployed to AWS, interacting with thousands of Android tablets using modern payments hardware, as well as partners through our API. Payment processing is a key source of Toasts revenue and also the lifeblood of our customers: we process multiple millions of dollars in transactions per day. Our payment processing systems operate in a highly secure environment with zero downtime, with our engineers practicing strong discipline to keep things running smoothly.

About this roll*:

  • Craft, build and maintain highly resilient, flexible and scalable architecture
  • Learn from our scaling problems, and implement solutions to those problems
  • Diagnose performance bottlenecks and implement optimizations
  • Review code to ensure technical implementations meet functional requirements
  • Mentor and guide less experienced engineers

Do you have the right ingredients*?

  • Respectful, empathetic, and humble
  • Build impactful systems that are critical to customer success
  • Passion for building great software
  • Balance getting things done with making things just right

*Bread puns encouraged but not required

Our Tech Stack

Our products run on a stack that ranges from guest and restaurant-facing Android tablets to backend services in Java to internal, guest-facing and restaurant-facing web apps. Our backend services follow a microservice architecture written using Java 8 and DropWizard; we use AWS extensively, ranging from S3 to RDS to Lambda. We have our own platform for dealing with user management, service elevations and robust load balancing. We store data in a set of sharded Postgres databases and utilize Apache Spark for large scale data workloads including query and batch processing. The web front-end is built using Angular and ES6. Our main point of sale application is an Android application written in Java and Kotlin. For data between tablets and our cloud platform, we operate RabbitMQ clusters as well as direct tablet communication to the back end.

"I looked at a lot of start-ups during my last job search and Toast was by far the most exciting. It was instantly obvious to me how the product is useful to people and why someone might want to buy it. The proof of that has been in the way we have grown and the excitement we have already generated. However, what really excites me about the company is that I feel like we are just scratching the surface in terms of what we can accomplish. There are SO many untapped opportunities around our product and as we continue to grow, I am excited about being able to explore them more.​"
