close - Site Reliability Engineer (USA Only - 100% Remote)
Requirements
• Senior 1 & 2 level candidates should have 5+ years of experience building modern infrastructure systems. • Staff level candidates should have 8+ years of experience. • The buck stops with you! You are the kind of person who is respected as an expert on the systems you run. • You have been the final point of escalation in the support of mission critical production systems • You are familiar with some of the following technologies: AWS, Terraform, Kubernetes, Ansible, MongoDB, PostgreSQL, Elasticsearch • You have a strong grasp of common networking and data transfer protocols such as DNS, HTTP, TCP • You are able to speak and write in English • You are located in the USA (ET, CT, MT, PT) • Contributed open source code related to our tech stack. • Have experience maintaining very large databases • Has been through a successful disaster response • Have experience with multi-region architectures • Have run MLOps systems
Responsibilities
• Automate our databases' full lifecycle. Provisioning, scaling, failover, retirement — multi-terabyte MongoDB, PostgreSQL, and Elasticsearch, handled by the platform instead of by hand. • Drive static credentials out of the system wherever they live. Move us toward short-lived, identity-based auth across services and infrastructure, shrinking the blast radius every quarter as Close moves upmarket. • Push downtime and disruption to new lows. Maintenance, deploys, and disaster recovery that customers never feel — building on a system that hasn't needed scheduled downtime in 4 years. • Harden our multi-region disaster recovery. Make failover faster, more automatic, and more trustworthy, so a regional outage is a non-event. • Own the telemetry and CI/CD backbone the whole company runs on. The Grafana LGTM + ClickHouse pipeline processing 130 TB a month, and the GitHub Actions + ArgoCD path that goes merged-to-production-to-rolled-back in 10 minutes. • A rock in the storm. With hard-won expertise gained through battles won and lost, you build robust systems from quality components fit to underpin mission-critical applications. You value simplicity over familiarity and resilience over speed, and you take pride in composable, maintainable tools. • Fluent across the infrastructure stack. You've worked with a wide range of tools and systems: CI/CD (GitHub Actions, ArgoCD), configuration management (Ansible, Terraform), databases (Elasticsearch, MongoDB, PostgreSQL, ClickHouse), cloud (Kubernetes, AWS), and telemetry (Loki, Tempo, Grafana, Mimir/Prometheus, OTEL). You pick the right tool for the problem rather than retreating to what you know. • The final point of escalation. The buck stops with you. You're respected as an expert on the systems you run, and you've been the last line of support for mission-critical production systems. You have a strong grasp of common networking and data transfer protocols like DNS, HTTP, and TCP. • Battle-tested. You've carried the pager for something with real customer impact, debugged incidents where the system didn't behave the way the runbook said it would, or come through a successful disaster response. You're drawn to the systems where edge cases actually matter. • Senior or Staff level. Senior 1 & 2 candidates have 5+ years building modern infrastructure systems; Staff candidates have 8+ years. You're comfortable in a fast-paced, fully distributed team where you manage your time well and communicate clearly in English. You're based in the USA (ET, CT, MT, PT).
