About the role

The role

We're looking for a world-class Head of Marketing to own growth and marketing end-to-end at Blaxel — demand gen, brand, content, PLG-ops, analytics, and automation. You'll move fast, test often, and build the foundation for scalable growth in a new category of cloud computing.

This is a hands-on role today with the path to lead the function tomorrow. We need someone who thinks like a mini-founder, wears many marketing hats, and earns the right to hire under them by proving channels first.

What you'll do

Working with cofounders and leveraging AI as much as possible, you'll build the marketing function from the ground up — across demand gen, brand, content, and PLG.

  • Launch and iterate on demand gen campaigns to hit our lead goals.
  • Sharpen brand, positioning, and messaging with the founders: what we say, who we say it to, and how it shows up across the funnel.
  • Build ICP lead lists and execute multi-channel outreach, mixing manual personalization plus AI scale.
  • Own analytics and attribution. Rigorously track what works, double down on it, kill what doesn't.
  • Own the PLG funnel (landing pages, signup, activation). Run experiments, find leaks, lift conversion.
  • Ship distribution plays beyond the funnel: community, dev events, GEO (generative engine optimization), PR.

Who you are

  • Player-coach. Today you'll roll up your sleeves and execute. Tomorrow you build the team under you. You don't hire before you do the work.
  • A generalist athlete. You've owned multiple marketing functions at a startup: content, demand gen, positioning, comms, ops.
  • Proven recent experience driving measurable growth at a cloud / platform / AI / ML / infrastructure company selling to developers, ideally in earlier stages.
  • Execution machine. Bias for action, experimentation, and rapid iteration. You thrive on a high-velocity, results-oriented team.
  • Deeply AI fluent. You use AI as a force multiplier on real marketing knowledge, not a substitute for it. You can explain why something works, not just what an LLM said about it.
  • Data-driven. Proficient with analytics, attribution, and using performance data to drive decisions.

Why us?

  • Build a category: You'll be shaping the growth engine for a new category of cloud computing, at the cutting-edge of AI infrastructure. The playbook for marketing to both humans and AI agents has yet to be written. You'll help us win the top 1% of AI companies of our generation.
  • Fast growth: We're growing extremely fast, and a substantial proportion of our revenue already comes from AI agents directly using us. We have strong customer love and close to zero churn on the product.
  • Direct impact & autonomy: You'll have the autonomy to build systems your way, with the full backing of the founders.
  • Tier-1 backing: We're repeat founders & backed by the best in the business (First Round, YC), giving us the resources and network to build a generation-defining company.
  • Competitive compensation: We offer a top-tier salary and comprehensive benefits, as well as some equity

About Blaxel

Blaxel is the perpetual sandbox platform for AI agents that need to run code fast. We let you keep infinite, secure code sandboxes on automatic standby while co-hosting your agents for near instant latency. This is enabled by our own technical backbone: a 25ms cold-start serverless compute engine.

Now processing billions of requests, we power the coding agents and background AIs for top AI startups & scaleups like Webflow or HumanBehavior. We solve the agentic infrastructure problems that traditional clouds aren’t built for, such has running AI code securely, statefully and with ultra-low latency — so that AI companies can focus on building generational products.

We raised a $7.3M seed round, led by First Round Capital.
