Help engineers fix what matters. You’ll work closely with PMs, designers, and engineers to build fast, reliable backends that power real‑time infrastructure insights for thousands of engineers.

• GMT2 to GMT-6 time zone
• Strong TypeScript experience. You know how to track down memory leaks and performance issues.
• You can write complex PostgreSQL queries, understand query plans and know when to reach for indexes, window functions, or CTEs. You’ve debugged deadlocks, optimized slow queries and can untangle gnarly data models.
• You move fast. You get a dopamine hit every time you release to production and jump on issues without hesitation.
• You’ve built something from scratch that you’re proud of.
• You’ll thrive in an amazing, experienced, hardworking, respectful, supportive, and fun team.

• Scaled to support customers with thousands of GitHub organizations and tens of thousands of repositories. This has required us to overhaul our APIs, interfaces, onboarding processes, infrastructure, and more.
• Automatically fixing infrastructure issues. With infrastructure changes there’s a lower tolerance for AI‑generated slop – there’s not the same safety nets in terms of testing and the risk is often higher. We’ve been iterating on our system that combines the AI‑generated changes with our best‑in‑class static analysis engine to robustly open good‑quality PRs to fix the most important issues for our customers.
• Built the Issue Explorer – a frontend and backend system for surfacing infrastructure issues at scale. We had to balance performance, UX, and data complexity to let enterprise customers filter, group, and chart tens of thousands of issues across their entire codebase.

• Customer not customer: It is all about seeing us and the customer as one. We like to be a part of the user’s team and help them however we can. If the user is not successful then we will not be either so we try to walk in their shoes. Its more than work – we build relationships and community with users and customers.
• Open is our core: Put yourself out there. Show your learning. Transparency builds confidence. Encourage sharing the good and the bad. The best decisions are made when everyone has access to all the data. Be straightforward and kind. Feedback is about your work, not your person.
• Lets JEDI: Lets Just Effing Do It! Own it and move fast. A good plan fiercely executed now is better than a perfect plan later. We ask for help and unblock each other. The main thing is to keep the main thing the main thing.

$600B is spent on cloud each year but no one knows the cost until it’s too late. We’re changing that.

Since launching Infracost in 2021, we’ve been pulled by engineers who all want to Shift FinOps Left. We enable them to proactively find and fix cloud cost issues before they hit production. We plug directly into developer workflows (like GitHub and Azure Repos), show cost impact in pull requests, enforce tagging and FinOps best practices and even generate PRs to fix issues automatically.

We’re backed by Sequoia, YC and trusted by Fortune 500 enterprises. You’ll join a small experienced and supportive team that’s shipping fast solving real infrastructure problems and having fun while doing it.

Whether you’re an engineer tackling complex systems (e.g. parsing massive Terraform repos, scaling real‑time systems), a product manager shaping strategy from real customer pain points or a customer success lead working directly with users; there’s meaningful work here for you. If you care about cloud efficiency, great UX and helping teams move faster and smarter we’d love to work with you!
