Full Job Description
You will
  • 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.


You are
  • 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.
  • Working with AI in your day-to-day. You use AI tools in your own workflow to ship faster and reason about unfamiliar parts of the system. We fund the use of AI tools (Claude Code, Codex, and other best-in-class developer tools) and treat learning and experimentation as part of the work. Bonus if you've run MLOps systems or scaled Temporal - both are live for us as we grow the agent platform.
  • 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).


Benefits
  • Compensation: Competitive pay plus an organization-wide goal-based bonus
  • Paid Time Off: ~5 weeks of PTO to start. Plus a 1-week all-company Winter Holiday Break and paid US holidays. You'll earn 2 extra days for every year you're with Close.
  • 80% Work Option: Work with your manager to choose between a standard 5-day week or a 4-day week at 80% pay
  • Parental Leave: Paid leave for primary and secondary caregivers
  • Sabbatical: A 1-month paid sabbatical every 5 years with the team
  • Healthcare (US residents): Two medical plans with Close covering 99% of your premium, plus Dental, Vision, HSA, FSA, and company-paid Long-Term Disability
  • 401k (US residents): We match your contributions up to 6%, vested immediately
