About this roll* (Responsibilities)

Do you have the right ingredients*? (Requirements)

Our Tech Stack

Our products run on a stack that ranges from guest and restaurant-facing Android tablets, to backend Kotlin and Java services, to internal, guest-facing, and restaurant-facing web apps. Our backend services follow a microservice architecture written using Kotlin/Java and DropWizard; we use AWS extensively, ranging from DynamoDB to RDS to Lambda. We have our own platform for dealing with user management, canary deployments, 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 React 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 rely on Pulsar event driven architecture along with some RabbitMQ clusters as well as direct tablet communication to the back end.

We believe learning new AI tools empowers us to build for our customers faster, more independently, and with higher quality.

The people who thrive here are those who embrace changes that let us build more for our customers; it’s a core part of our culture.
