About the role

Key responsibilities & impact
  • Plan and execute infrastructure migrations, the kind where the wrong call takes the product down.
  • Be the last line of defence when things break: diagnose it, fix it, and make sure it doesn't happen again.
  • Use quantitative data (error logs, cloud metrics) and qualitative data (support tickets, user reports) to identify the highest-leverage reliability improvements.
  • Build and maintain the scripts, workflows, and cloud architecture that the product runs on.
  • Work closely with product engineers to review new features before they ship, ensuring they meet the reliability bar before they reach production.
  • Own the reliability standard across your product area, so new features and onboardings don't break what's already working.

Requirements

What you’ll need
  • Solid TypeScript. Expert level. If you don't have this, you shouldn't apply.
  • Serious cloud experience. Google Cloud or equivalent, at depth.
  • Deep database knowledge. Not just querying, but designing.
  • Production ownership. When something breaks, you're the one who fixes it.
  • Fullstack capability. You'll be designing and building features alongside our product engineers.
  • Genuine obsession with learning. Everyone says this. We mean it differently.
