Site Reliability Engineer (USA Only - 100% Remote)

About Us

Since 2013, we've been building a CRM that gets out of your way and helps your team sell more, faster. No manual data entry, no 10-click workflows. Just communication-first sales software designed to help you succeed and scale. We're bootstrapped and profitable which means we answer to our customers and play by our rules. We're proud of our 120-person, 100% remote team, focused on building Close so that no small, scaling business fails because it can't figure out sales.

The Platform

• Multi-terabyte MongoDB, PostgreSQL, and Elasticsearch clusters
• Tens of thousands of pods running on multiple Kubernetes clusters
• Telemetry on Grafana's LGTM stack and ClickHouse processing over 130 TB a month
• CI/CD pipelines that build Docker images, run automated tests, and deploy to our clusters
• A well-documented public API that is consumed by our front-end TypeScript app as well as numerous integrations
• Infrastructure heavily automated using Terraform, Ansible, and other AWS tools
