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.

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 in Go, which consists of loosely coupled docker-containerized microservices communicating via RESTful APIs and pub-sub queues. 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.

You will apply software engineering principles to operations, focusing on the core SRE objectives of stability, performance, and automation. Crucially, you will act as a force multiplier by empowering our development teams.

• →Service Reliability & Observability: Drive SRE efforts to enhance the platform's overall resilience, uptime, performance, and stability.
