Your impact

We're looking for a Founding Growth Lead who is equally hands-on in driving the market expansion and accelerating adoption across the developer ecosystem. This is a critical, cross-functional role that will own the entire growth funnel, from developer awareness and acquisition to engagement and retention. You will be the architect of a technical growth engine, integrating product, engineering, and marketing to drive sustained developer adoption, accelerate activation and retention, and translate product adoption into revenue growth.

What you’ll do

• Define and build the growth function from the ground up, establishing the technical infrastructure, frameworks, and repeatable processes that will scale
• Develop and execute strategies to create, engage, and grow our audience across marketing channels (Google, Linkedin, Meta, Reddit, X, etc.) and all possible developer touchpoints
• Partner with product and engineering leadership to influence roadmap prioritization, pricing, and packaging strategy using growth data, funnel analysis, and user insights to inform monetization decisions and conversion optimization
• Build a thriving developer ecosystem, fostering community engagement and advocacy
• Coordinate high-impact product launches that generate significant visibility, leveraging newsletters, podcasts, press, publications and other outlets
• Create viral campaigns leveraging product capabilities to reach and convert developers
• Drive SEO, content strategy, and performance marketing initiatives across every channel where developers discover, evaluate, and adopt new tools
• Build and maintain marketing infrastructure, tracking, dashboards, attribution tooling
• Own technical content, from blog posts and landing pages to demo script and onboarding flows

What you’ll bring

• Former founder or seasoned growth leader with experience scaling early-stage, high-growth companies
• Strong product or engineering background with technical fluency, able to design and implement technically driven growth systems
• Deep analytical skills: comfortable with growth modeling, cohort analysis, A/B experimentation, funnel diagnostics, and data-driven decision-making
• Track record of running product launches and campaigns that directly accelerated adoption and revenue
• Hands on experience managing performance marketing budgets, paid channel strategy, and attribution across the full funnel
• Thrive in ambiguity and see constant change as opportunity, not obstacle
• Naturally spend nights and weekends hands-on with the latest technical innovations
• Bring ideas and solutions, not org charts and territory-building
• Consider marketing as a product surface that can be engineered and automated
• Prior exposure to a product-led growth strategy and usage-based business model
• BA/BS degree or higher, with technical degrees a plus

Candidates must be based in the SF Bay Area or willing to relocate (you will be working on-site in our South Bay office a few days a week).

The US base salary range for this full-time position is $190,000 - $270,000 + bonus + equity + benefits.
