About nesto and Nesto Cloud

nesto is Canada’s leading provider of mortgage technology and financing solutions, managing $73B+ CAD in residential and commercial mortgages, with 1,000+ team members across 12 offices nationwide. You will be working on Nesto Cloud, Canada’s most advanced cloud platform, delivering end-to-end technology solutions for lenders in the digital age.

About the team 

Several major tech projects are progressing in parallel at a high delivery pace. Structured by squads, the tech teams are working on different products and nesto experiences based on strong algorithms and AI to meet business objectives. Our technology allows customers to shop and access mortgage products by enabling them to complete their mortgage applications and transactions digitally.

From the very beginning, we created a modern, cloud-native tech platform (based on Google Cloud) adhering to the industry's highest standards in terms of development and operation processes. Our front-end is written in Typescript with React and our back-end in Go, in the form of loosely coupled docker-containerized microservices, well decoupled via RESTful APIs and pub-sub queues, and isolated behind different API gateways. Those containers are orchestrated using Kubernetes, instrumented with Datadog. Our CI/CD pipelines are automated using Google Cloud Build and Codefresh and our infrastructure is managed using Pulumi.
