Improve developer experience and engineering productivity by building tools and workflows that make it easier for engineers to develop, test, and ship software.

Maintain infrastructure automation with Ansible, Terraform, and Terragrunt.

Improve the reliability and performance of our CI/CD workflows.

Find the causes of slow builds, failed pipelines, and flaky tests.

Develop internal tools, improve test infrastructure, and occasionally work on product features.

Improve observability across our infrastructure and delivery workflows using OpenTelemetry, ELK.

Leverage AI to improve engineering workflows by building cloud-based agent tools and helping teams adopt effective practices.
