About the role
Own and drive the architectural direction for our new product(s). These new products don’t exist in the industry today. You will be designing and building the next generation of AI native developer tooling. Expertise in building products that customers love. You’ll have come from a background where you have set and led the technical direction of a product from an early stage and developed that product through to one which is recognized industry wide as delivering an exceptional customer experience.
What they're looking for
- Track record of leading through influence and shaping technical direction while operating as an individual contributor
- Strong communication skills, with the ability to explain complex technical concepts to engineers, leadership, and non-technical stakeholders
More about this role
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 10x so far in 2026.
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.
