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.
