Senior Site Reliability Engineer

The Opportunity

Two mature SaaS products, two separate stacks, US and EU regions, tens of millions of end users, and no one fully owning reliability yet. That is your seat. In 90 days you will have both environments mapped, SLOs and alerting live, and an on call rotation running, plus one measurable win on uptime or cloud spend. You report straight to the CTO, so your decisions set the standard for how a small, AI heavy team scales.

What You'll Own

• SLOs for the paths customers feel first (SDK delivery, login, the product builder, AI features), backed by alerts people actually act on

• Kubernetes, networking and autoscaling on GCP and/or AWS across both regions, with upgrades that land quietly and cloud plus LLM spend trending down

• The data layer: ClickHouse alongside Postgres or MySQL, with replication, backups you have actually restored, and capacity that stays ahead of growth

• Infrastructure as code across cloud, networking and Cloudflare, until nothing important is configured by hand

• Incident leadership: rotation design, response, root cause, and the follow through that stops repeats

• A release pipeline that lets the team ship several times a week, with progressive rollouts and rollbacks in minutes

• Enterprise readiness: tenant isolation, rate limiting, dedicated environments, and the controls and evidence behind SOC 2
  

What We're Looking For

• 7+ years in SRE, DevOps or platform engineering, including 3+ owning production for a SaaS product

• Deep hands on GCP and/or AWS

• Kubernetes in production: deploys, networking, scaling, version upgrades

• Terraform or an equivalent IaC tool used on real production systems

• ClickHouse or another columnar database in production, plus PostgreSQL or MySQL

• Experience running distributed, multi region systems and leading incidents end to end

• CI/CD with progressive delivery and a proven rollback strategy

• C1 or C2 English, comfortable walking engineers and executives through infrastructure tradeoffs
  

Nice to Have

• Daily use of AI coding agents (Claude Code or similar) in infra work

• Depth in the Grafana stack: Prometheus, Loki, OnCall

• Hands on time in a SOC 2 or ISO 27001 audit

• Operating embedded JavaScript or mobile SDKs at high volume
