The posting

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 https://docs.blacksmith.sh/ 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).

- Help enable our sales team to speak to what's new as soon as it ships.

- Track engagement and adoption metrics after a launch to keep refining the strategy over time.

Social media presence

- Publish a regular and engaging stream of content on X, LinkedIn, etc.

- Identify the most interesting work our engineers are doing and turn it into something worth sharing.

- Create high-quality and engaging short videos and graphics.

- Join the conversation: engage with the developer ecosystem on our socials, building brand awareness and bringing back product feedback to our team.

Technical writing and customer stories

- Help our engineers convey what they’re building in written form and edit until the message lands.

- Collaborate with Growth to identify and fill gaps in topics where developers and AI search can't find us yet.

- Surface insights from real customer experiences https://www.blacksmith.sh/customers and results to feed back into our messaging, content, and proof for what we’re building.

What this role isn't

- A sales-materials job (i.e., not primarily pitch decks and sales enablement).

- Paid, brand or demand-gen marketing.

- Community management or events.

- Writing a strategy doc and relying on others to build and ship it.

YOU'RE A GOOD FIT IF YOU

- Are technical. You've built software and can read a PR or design doc and explain why it matters. Some of the best people for this role are developers seeking a more creative outlet or marketers who code.

- Can deeply understand our product and roadmap well enough to demo it from memory.

- Have shipped things that resonate with developers: docs, launches, videos, threads, posts.

- Write engaging and convincing copy with a point of view (and like a developer speaking to developers).

- Are “chronically” online and know what's trending on developer X and Hacker News.

- Have a high motor. You spot problems and fix them without being asked.

- Enjoy working in person 5 days a week in SF or NYC.

BONUS

- You've run launches at a developer tools or infrastructure company.

- You make videos and graphics yourself, or are eager to learn with agentic tools.

- You've built and maintained an audience of your own.

- You have experience testing and measuring what works (from social media engagement to customer success metrics).

HOW WE HIRE

- An intro call, then 1-2 conversations with a founder or member of the team.

- On-site: we give you an example product / feature in the morning, you plan and build its launch (assets, launch-day posts, week-one and week-two plan), and we review it together at the end of the day

COMPENSATION AND BENEFITS

- Medical, Vision, and Dental insurance.

- Competitive base + equity.

- 401k match.

- Unlimited PTO.

- Annual offsite.

- Early-exercise stock options

- 12 weeks fully paid parental leave (US)

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
