Developer Marketer

About the role

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.

What you'll own

Documentation as a product

For many developers, our docs are their first real impression of our products.

-

Keep them accurate and informative as our products evolve, and cut anything that doesn't earn its place.

-

Redefine how they look and read.

-

Make them as useful to coding agents as to the people using them.

Launch machinery

We have an exciting roadmap of products and features shipping rapidly, and each one deserves to land.

-

Plan and run launches of every size, from new products to new features, moving fast without cutting corners.

-

Build a repeatable playbook for each launch day and beyond: the announcement, media kit, social posts, email blasts, customer communications, and follow-up content in the weeks thereafter (e.g., real metrics and customer quotes).
