As a Senior Infrastructure Engineer on the Compute & Storage Platform team in Toast, you will design, build, and operate the foundational distributed systems powering the Toast platform as the company expands into further international markets and broadens its product offerings to encompass retail shopping.
You will bridge the gap between core infrastructure and cutting-edge product development—building low-latency state and storage systems, scalable compute clusters, and high-throughput streaming pipelines. Your work will directly enable Toast product delivery across our Product Development Life Cycle (PDLC).

1. Core Infrastructure & Automation
2. Storage & Compute Operations
3. Systems Reliability & Observability
Our Tech Stack
Toast’s commercial products run on a stack that ranges from guest and restaurant-facing Android tablets to backend microservices, guest- and restaurant-facing web apps, payment systems, event buses, and more.
The Infrastructure Engineering group manages Toast's infrastructure via the AWS API, using configuration management tools like Terraform, Ansible, and internally developed clients using Python and Go. We rely heavily on Datadog and Splunk for monitoring and observability and on FireHydrant for alerting and incident response.
Infrastructure Engineering provides the products and services to support, deploy, and monitor our product suite, which uses a microservice architecture written using JVM and Node.js apps. AWS products are also in heavy usage, ranging from S3 to RDS, DynamoDB, ECS, Lambda, and many others. We have our own platform for user management, service discovery/elevations, and load balancing. We use Apache Spark for large scale data workloads including query and batch processing. The main Toast POS application is an Android application written in Java and Kotlin. For data synchronization between tablets and our cloud platform we operate RabbitMQ and Apache Pulsar clusters as well as direct tablet communication to the applications' RESTful and GraphQL APIs.
Why Join Us?
You will be at the ground floor of building the data-storage systems that powers our flagship products. You'll solve complex, high-scale infrastructure challenges at the intersection of distributed storage and compute.
