Responsibilities

  • ▹Automate the databases' full lifecycle: provisioning, scaling, failover and retirement of multi-terabyte MongoDB, PostgreSQL and Elasticsearch, handled by the platform instead of by hand
  • ▹Drive static credentials out of the system, moving toward short-lived, identity-based auth across services and infrastructure
  • ▹Push downtime and disruption to new lows for maintenance, deploys and disaster recovery that customers never feel
  • ▹Harden multi-region disaster recovery to make failover faster, more automatic and more trustworthy
  • ▹Own the telemetry and CI/CD backbone: the Grafana LGTM + ClickHouse pipeline processing 130 TB a month, and the GitHub Actions + ArgoCD path

Requirements

  • ▹Senior or Staff level: Senior 1 & 2 candidates have 5+ years building modern infrastructure systems; Staff candidates have 8+ years
  • ▹Fluent across the infrastructure stack: 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)
  • ▹Build robust systems from quality components, valuing simplicity over familiarity and resilience over speed
  • ▹Be the final point of escalation and last line of support for mission-critical production systems
  • ▹Strong grasp of common networking and data transfer protocols like DNS, HTTP and TCP
  • ▹Use AI tools in your day-to-day workflow
  • ▹Battle-tested: carried the pager for something with real customer impact, debugged incidents off-runbook, or come through a successful disaster response
  • ▹Comfortable in a fast-paced, fully distributed team, managing time well and communicating clearly in English
  • ▹Based in the USA (ET, CT, MT, PT)
