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 interest into a scalable, measurable top-of-funnel engine.

As our first dedicated PLG Growth Marketer, you'll own everything pre-sign up: building the campaigns, experiments, and content needed to drive awareness, increase free product sign-ups, and get developers and security engineers in the door. You'll sit within the Global Campaigns & Growth Marketing team and work closely with Product, Lifecycle, and Web to connect marketing motion to free product adoption. A key part of this role is partnering with the Product Growth and Engineering teams to facilitate a clean handoff of new sign-ups, ensuring the users marketing brings in are set up for the activation and adoption work those teams own downstream.

This role is for someone with high agency, strong experimentation instincts, and a bias toward building and testing fast.

LOCATION EXPECTATIONS

• Our expectation is that this role will be hybrid - requiring 2-3 days a week in our San Francisco office.

• Own campaign strategy and messaging end to end, from concept through execution and reporting.
• Build mini-campaigns tied to specific features, use cases, and product moments to drive targeted acquisition.

MESSAGING & CONTENT

• Develop and own top-of-funnel messaging that speaks to developers and security engineers in a way that resonates.
• Create and test content across formats including ads, landing pages, email, and organic social to drive awareness and sign-ups.

• Run experiments across acquisition channels, landing pages, CTAs, and campaign messaging.
• Document learnings and share them broadly so the team compounds on what works.
• Reporting & Measurement
