About the role

Key responsibilities & impact
  • Managing large fleets of EC2-based VMs, disks, and networking for data-intensive workloads
  • Improving operational tooling around deploys, schema changes, backups, restores, and incident response
  • Working closely with ClickHouse engineers to turn database-level needs into infra-level solutions
  • Reducing operational load by identifying repeat pain points and eliminating them through code and self-healing automation
  • Participating in on-call and incident response, with a strong focus on making incidents rarer over time
  • You’ll have room to design and automate, not just respond to alerts.

Requirements

What you’ll need
  • Prior experience with ClickHouse or other OLAP databases
  • Strong experience operating production infrastructure on AWS
  • Hands-on experience with VM-based systems (EC2), not just managed PaaS
  • Experience automating infrastructure using tools like Terraform, Ansible, or similar
  • Solid understanding of Linux systems (disk, memory, networking, failure modes)
  • Experience supporting stateful systems (databases, queues, storage systems, etc.)
  • Ability to debug and reason about performance and reliability issues in production
  • You’re comfortable owning systems end-to-end, including on-call responsibilities

Benefits

Comp & perks
  • Transparency: Everyone can read about our roadmap, how we pay (or even let go of) people, our strategy, and how we work, in our public company handbook. Internally, we share revenue, notes and slides from board meetings, and fundraising plans, so everyone has the context they need to make good decisions.
  • Autonomy: We don’t tell anyone what to do. Everyone chooses what to work on next based on what's going to have the biggest impact on our customers, and what they find interesting and motivating to work on. Engineers lead product teams and make product decisions. Teams are flexible and easy to change when needed.
  • Shipping fast: Why not now? We want to build a lot of products; we can't do that shipping at a normal pace. We've built the company around small teams – autonomous, highly-efficient groups of cracked engineers who can outship much larger companies because they own their products end-to-end.
  • Time for building: Nothing gets shipped in a meeting. We're a natively remote company. We default to async communication – PRs > Issues > Slack. Tuesdays and Thursdays are meeting-free days, and we prioritize heads down building time over perfect coordination. This will be the most productive job you've ever had.
  • Ambition: We want to solve big problems. We strongly believe that aiming for the best possible upside, and sometimes missing, is better than never trying. We're optimistic about what's possible and our ability to get there.
  • Being weird: Weird means redesigning an already world-class website for the 5th time. It means shipping literally every product that relates to customer data. It means building an objectively unnecessary developer toy with dubious shareholder value. Doing weird stuff is a competitive advantage. And it's fun.
