Quick Summary

Overview

We started by building infrastructure to run CI workloads really fast.

Technical Tools
Office ManagerAdministration & Office Support
  • We started by building infrastructure to run CI workloads really fast. Our first product helps companies run GitHub Actions substantially faster and cheaper by owning and operating our own global fleet of bare-metal machines rather than renting generic cloud VMs.

  • Today, we orchestrate tens of millions of Firecracker VMs each week, running CI for 7,000+ companies and tens of millions in ARR. We’ve grown 20x in the past 12 months.

  • We operate thousands of bare-metal machines across multiple regions, regularly schedule 100k+ vCPUs concurrently, and run a petabyte-scale Ceph cluster that we manage ourselves.

  • We’ve raised $58.5M from Seed to Series B, led by Google Ventures (GV) & Peak XV Partners, and we’re intentionally building a small, but exceptional team.

  • Blacksmith was founded by a team with deep systems and scaling experience, including building search/ads infrastructure at Faire, and operating large distributed systems at Cockroach Labs. Our GTM is led by Jon Boyer, formerly Head of Sales at Zapier.

  • We're now extending the same CI infrastructure into a broader platform: running agent sandboxes at scale and building our own background coding agent on top of it.

As Office Manager, you will own the day to day operations and workplace experience for the Blacksmith San Francisco office.

This is a crucial role. We are an in-person team and we want everyone to enjoy the environment they work in. Your role will deliver an experience that means people want to come in, and guests leave feeling impressed.
