ABOUT THE ROLE Semgrep has a large and growing base of developers and security engineers who use our product every day, many of them before they ever talk to sales. This role exists to turn that organic adoption into a scalable, measurable growth engine. As our first dedicated PLG Growth Marketer, you'll own the motion that converts free users into pipeline: building the programs, experiments, and cross-functional alignment needed to identify high-intent users, accelerate their path to value, and route the right signals to sales at the right time. You'll sit within the Global Campaigns & Growth Marketing team and work closely with Product, Lifecycle, RevOps, and Sales to connect in-product behavior to marketing motion. This is a high-impact, high-visibility role for someone who is equally comfortable in data and strategy, and who knows how to build in an environment where the playbook is still being written. LOCATION EXPECTATIONS Our expectation is that this role will be hybrid - requiring 2-3 days a week in our San Francisco office. WHAT YOU'LL OWN FREE-TO-PAID CONVERSION - Define and own the free-to-paid funnel from activation through opportunity conversion, with clear KPIs at every stage. - Identify and prioritize the highest-value cohorts within Semgrep's free user base based on product usage, engagement signals, and firmographic data. - Build programs including in-product, email, paid, and direct outreach that move high-intent users toward demo and sales engagement.

ACTIVATION & ONBOARDING - Map the activation journey for new free users and identify where drop-off occurs. - Partner with Product and Lifecycle to develop onboarding touchpoints including in-product messaging, triggered emails, and targeted campaigns that reduce time to value. - Work closely with the Product team to design and run experiments across acquisition and activation stages from first touch through feature adoption using shared data to prioritize what to test and act quickly on results. - Run experiments to improve activation rates across key user segments (developers, AppSec engineers, platform teams). GROWTH EXPERIMENTATION - Build and maintain a structured experimentation roadmap: hypotheses, tests, results, and iteration. - Run A/B and multivariate tests across onboarding flows, landing pages, in-produc ...
