Skills: CI/CD
ABOUT BLACKSMITH - 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 10,000+ companies and tens of millions in ARR. We’ve grown 20x so far in 2026. - We operate thousands of bare-metal machines across multiple regions, regularly schedule 300k+ vCPUs concurrently, and run a petabyte-scale Ceph cluster that we manage ourselves. - We’ve raised $125M from Seed to Series C, led by Sequoia, 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. OUR DEVELOPER MARKETER At Blacksmith, we ship a lot: new products, new features, and a steady stream of engineering work worth showing off. But the more we build and the faster we move, the wider the gap between what Blacksmith can do and what developers know it can do. Closing that gap is the job. We're looking for a Developer Marketer who is equally at home in a codebase and a content calendar to own how developers find, understand, and adopt Blacksmith. You'll be embedded with our engineering team, with a front-row seat to what we’re building and why it matters. You’ll also work closely with the founders and growth team to shape how we launch and how developers discover us.
