You will have wide latitude to set the marketing vision, from narrative and content to demand and category creation, working directly with the founders in a fast-paced, high-ownership environment. Responsibilities • Own and shape the overall marketing strategy, narrative, and brand voice. • Design and execute creative, out-of-the-box campaigns that stand out in a crowded market. • Lead SEO and GEO strategy to drive organic discovery and growth. • Create technical content credible to engineers, across blog posts, launches, paid experiments, and events. • Build the product marketing motion as the company shifts toward product-led growth. • Measure and report on pipeline influenced and demand created. Requirements • A hybrid marketer who is both highly creative and technically fluent. • Experience marketing developer tools, infrastructure, or AI products to technical buyers. • Strong understanding of SEO and GEO. • A track record of inventive, memorable marketing campaigns and programs built from scratch. • Experience at a pre-Series C startup; former founder or first marketing hire is a plus. • Bias for action and the ability to operate independently in a fast-moving environment. • Able to work onsite in San Francisco five days per week.
