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.

What You'll Own

Top-of-Funnel Campaigns

• Develop and execute campaigns across paid, organic, and owned channels designed to drive awareness and free product sign-ups.

• 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.

Landing Pages & CRO

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.

• Stay close to what competitors are doing and use that to sharpen our positioning and messaging.

Experimentation

• Build and maintain a structured experimentation roadmap: hypotheses, tests, results, and iteration.

• 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

• Own top-of-funnel reporting: traffic, sign-up volume, channel performance, and campaign attribution.

• Define and track KPIs that tie marketing activity to free product growth.

• Present performance and learnings to product and marketing leadership on a regular cadence.
