Job Description:

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 2,000 companies and hit ~$10M in ARR in less than 2 years. We operate thousands of bare-metal machines across multiple regions, regularly schedule 50k vCPUs concurrently, and run a petabyte-scale Ceph cluster that we manage ourselves. We’ve raised $13.5M across Seed and Series A, led by Google Ventures (GV), 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. What you’ll own Product Marketing Translate complex technical features into clear customer value. Build collateral (case studies, decks, one-pagers) that help prospects and customers understand why they should choose Blacksmith. Drive customer education through docs, email campaigns, and onboarding guides. Growth & Demand Generation Define and track core growth metrics: weekly inbound leads, pipeline created, and conversion rates. Build repeatable demand channels beyond launches (ads, content distribution, email campaigns, partnerships). Experiment with paid acquisition and measure ROI rigorously. Brand & Content Carry forward a high bar for quality, creativity, and personality in our brand. Own social presence (X, LinkedIn) and ensure consistency with our voice. Drive thought leadership: blogs, podcasts, PR placements, and founder amplification. Create compelling customer stories, launch videos, and product announcements. Events & Partnerships Run high-ROI events and conferences with a tighter filter on spend vs. return. Build relationships with influencers, creators, and ecosystem partners where it makes sense. Collaborate with design and creative partners on swag, landing pages, and experiences. Team & Leadership Build and lead a small but high-leverage marketing team across product marketing, events, growth, and content. Set up clear goals, reporting, and accountability (weekly lead tracking, campaign ROI, etc.). Partner with founders on GTM, sales, and fundraising announcements. What we value Taste and quality : You believe that details matter, from landing pages to launch videos. Bias to action : You proactively identify problems and take them to the finish line. Originality : You’re not here to copy what everyone else is doing. You bring creativity and bold ideas. Team player : You can lead with conviction but also collaborate, listen, and adapt. Marketing is a team sport, not a solo performance. Data-driven : You can back up intuition with metrics and know how to measure what matters. 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)
