  • We work in-person in Sydney, Australia, and hire globally.

How we work

  • User-first: We build what people want. We invest time to understand our users and focus on adding value instead of extracting value.
  • High agency, high ownership: We own outcomes end-to-end. When something goes wrong, we take responsibility and fix it.
  • Urgency: We prioritize ruthlessly, increase leverage, and move at an exceptional pace.

What you'll do

  • You’ll be our first dedicated site reliability engineer, owning reliability and core platform decisions as we scale to hundreds of millions of users.

Example projects

  • Improve uptime and reduce RTO across critical services.
  • Orchestrate and harden GPU clusters serving millions of AI generations per day.
  • Implement platform-wide observability (metrics, tracing, alerting) and enforce SLOs.
  • Optimize AWS infrastructure and reduce cloud spend without sacrificing performance.

What you'll bring

  • 5+ years operating production systems at scale.
  • Strong AWS experience (infra-as-code, high-scale compute, K8s/ECS or similar).
  • Deep observability and incident response experience.
  • CI/CD and deployment pipeline expertise.
  • Familiarity with our tech stack: TypeScript, Next.js, React, TailwindCSS, tRPC, Postgres, Temporal, AWS.
  • You write code and fix root causes, not just symptoms.
  • Hunger to win. This is not going to be easy.

What we offer

  • Top-of-market compensation with meaningful equity upside.
  • Real ownership from day one. Work on important problems and see the impact of what you ship.
  • Fast-growing scope. As your impact grows, your responsibility and compensation should grow with it.
  • A company card for food, coffee, tools, and anything that helps you do your best work.
  • Daily team lunch and dinner at the office.
  • An unlimited workspace budget to build your ideal setup.
  • Visa sponsorship and relocation assistance for people moving to Sydney.

How we think about comp

We raise the ceiling for exceptional performers , not the floor. As your impact grows, your compensation should too.

  • The listed range is cash + equity, with superannuation on top.
  • We review compensation every 6 months.
  • Bonuses reward past impact, and raises reflect your new level.

Our interview process

  • Intro call: 15 minutes to align on the role and company.
  • Founder interview: go deep on what you’ve built, how you think, and how you work.
  • Technical interview: 1 hour of system design and technical discussion. No live coding.
  • Paid work trial: spend 3 days with us in Sydney working on a real problem. We cover travel and accommodation, if needed.
  • Offer: if it’s a strong fit, we move quickly.
