About You
You are a builder at heart — curious, pragmatic, and motivated by hard infrastructure problems. You thrive in early-stage environments where speed and ownership are critical. You act as a driver, not a passenger, and you want to be part of a small team where your contributions have outsized influence.
You love designing systems that scale across clouds, automating everything you can, and building platforms that make other engineers more productive.
You care deeply about reliability, security, and operational excellence.

Our platform runs on AWS as a multi-tenant SaaS product — you'll help extend it to support customer-owned cloud deployments across AWS, GCP, and Azure over time.
You'll design deployment automation, build internal tooling, and support enterprise customer deployments, sitting at the intersection of platform reliability, customer delivery, and engineering productivity.

Work with enterprise customers to deploy Clarasight into their cloud accounts.
Build tooling and documentation that makes deployments scalable and repeatable.
Reliability & Observability
Design monitoring, logging, and alerting across distributed environments.
Establish best practices for security, networking, and access management.
Engineering Enablement
Build internal tooling that makes it easier for product engineers to deploy and operate services.
Help define DevOps and CI/CD best practices.
You'll Be a Great Fit If You…
Have 4+ years in infrastructure, platform engineering, or DevOps.
Have strong hands-on AWS experience and familiarity with IaC tools like Terraform.
Have built CI/CD pipelines and automated deployment systems.
Have designed or operated production systems in cloud environments.
Thrive in fast-paced, early-stage startup environments.
