About the role
What we're looking for:
We need someone with 5+ years of experience who has owned products end-to-end, from ideation through launch, in a startup or high-growth environment. You should be comfortable building 0-to-1 products in ambiguous spaces and have a track record of shipping developer tools or engineer-facing products that set a high bar for user experience. Bonus points if you've worked in developer tooling, AI-powered products, or have experience building coding agents or CI/CD platforms.
What you'll do:
- Own entire product surfaces end-to-end — from early ideation and systems design through to shipping and iterating with customers
- Build and evolve next-generation developer tools (including Codesmith, our background coding agent) — designing workflows, UI, and infrastructure that let engineers delegate coding tasks to AI
- Work closely with founders to formulate product ideas, validate them, and bring them to market in days, not months
- Make critical architectural and systems design decisions across the full stack that will define products for their lifetime
- Prototype and iterate rapidly on AI-powered features — from natural language interfaces to automated fix generation — owning everything from prompt design to backend service to UI
- Ship polished, high-performance product surfaces across analytics, observability, and agent platforms where engineers interact daily

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 month, running CI for 3,000+ companies and hit ~$10M in ARR in less than 2 years. We’ve already more than 5X’d revenue since the start of 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 Capital, 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.
