Life at Nesto Cloud
At Nesto Cloud, you'll build the future of lending alongside some of the country's top developers, AI engineers, and mortgage experts. You'll work with a modern tech stack and AI-driven development frameworks designed to help you innovate, grow your skills, and accelerate your career.
About the role Since the beginning, we've been committed to creating a modern and cloud-native tech platform (based on Google Cloud) that adheres to the industry's highest development and operation standards. Our front-end is written in TypeScript with React, and our back-end is in Go, consisting of loosely coupled Docker-containerized microservices communicating via RESTful APIs and pub-sub queues, and isolated behind different API gateways. These containers are orchestrated using Kubernetes and monitored with APM via Datadog. Our CI/CD pipelines are automated using GitHub Actions, ArgoCD, and our own open-source config management tool Joy. All infrastructure configuration is managed using Infrastructure as Code via Pulumi (similar to Terraform, but using a rich and extensible programming language and API, in our case, TypeScript), ArgoCD and Crossplane.
We strive to implement the best emerging DevOps practices, such as GitOps, Internal Developer Platforms, and Infrastructure as Code. We believe that DevOps goes beyond the mere automation of pipelines; it should encompass all areas of the business, empowering its actors and stakeholders to actively contribute to the organization's overall success.
