Head of Growth

About the Role We're a seed-stage AI infrastructure company backed by top-tier investors, building the testing and sandbox layer for AI agents and agent-facing software. Our platform lets engineering teams train and validate AI agents against realistic, stateful "twins" of third-party services — safely, repeatably, and without touching production. We're a small, high-velocity team at the very start of our journey, and we're looking for a Head of Growth to join us on-site in San Francisco and own everything that drives awareness, adoption, and revenue. This is a founding-team-level role. You'll work directly with the co-founders, shape our go-to-market strategy from scratch, and have an outsized impact on the company's trajectory. If you thrive in zero-to-one environments, are energized by the AI/ML developer tooling space, and love turning early traction into repeatable growth, we'd love to talk. What You'll Do Own the full growth funnel — from top-of-funnel awareness to activation, retention, and expansion. Define and execute a go-to-market strategy targeting AI/ML engineers, platform teams, and developer tooling buyers. Build and run demand generation programs across channels (content, SEO, developer communities, partnerships, paid, etc.). Establish core growth metrics, set targets, and report on performance with a data-driven mindset. Work closely with the founding team to translate product capabilities into compelling narratives and positioning. Identify and develop partnerships, integrations, and community relationships that accelerate distribution. Lay the foundation for a growth function — processes, tooling, and eventually a team — as the company scales. What We're Looking For Required: 2–8 years of experience in growth, marketing, or equivalent leadership roles — ideally at a high-growth startup. Proven track record of driving measurable pipeline or user growth, not just running campaigns. Comfortable operating as a generalist: you can write copy, run an experiment, read a dashboard, and present a strategy in the same week. Strong communicator who can distill complex technical products into clear, compelling messages for developer audiences. Entrepreneurial mindset — you take ownership, move fast, and figure things out. Based in or willing to relocate to San Francisco, CA; this is a fully on-site role. Nice to Have: Familiarity with or hands-on experience in the AI/ML or developer tooling space. Experience marketing to software engineers, platform/DevOps teams, or technical buyers. Prior experience at or knowledge of companies in the AI testing, agent infrastructure, or DevTools ecosystem. Location This is a fully on-site role based in San Francisco, California, USA . Visa sponsorship is available for qualified candidates. Compensation & Benefits Compensation details will be discussed during the interview process and will be competitive for a seed-stage company at this stage of growth. Equity will form a meaningful part of the package given the seniority and early-stage nature of the role.
