Learn more at semgrep.dev . 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.

Requirements

Have 4+ years of experience in growth marketing, product marketing, or a hybrid role at a B2B SaaS company with a developer or technical audience.
Have hands-on experience with a PLG or developer-led GTM motion and understand how free users behave differently from traditional MQLs and how to build programs accordingly.
Are deeply data-driven. You know how to instrument a funnel, build a cohort analysis, and turn behavioral data into a marketing program.
Are comfortable working with product and engineering teams. You don't need to code, but you speak their language and can translate between technical behavior and marketing action.
Have built or contributed to PQL frameworks and understand how to align marketing, sales, and product around a shared definition of user readiness.
Are a strong experimenter: you know how to design a test, avoid common pitfalls, and learn fast from the results.
Have experience with tools to gather product analytics; Marketo for lifecycle; Salesforce for pipeline tracking; and intent or engagement platforms like Common Room or Dreamdata.
Understand the developer and AppSec buyer and have marketed to both developers and security practitioners and know how their buying behaviors differ.

Nice To Haves

Experience at a security, developer tools, or open-source company.
Familiarity with community-led growth motions and how open-source communities can serve as a top-of-funnel channel.
Experience building or contributing to a developer advocate or community program.
Background in conversion rate optimization (CRO) across landing pages, product sign-up flows and in-app prompts that push users towards an upgrade conversation.

Responsibilities

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.
Product-Qualified Lead (PQL) Strategy Partner with Product, RevOps, and Sales to define what a PQL looks like at Semgrep including what signals, thresholds, and behaviors indicate readiness to buy.
Build the infrastructure and workflows to route PQLs to the right motion: self-serve upgrade, lifecycle nurture, or sales-assisted.
Continuously refine PQL scoring based on conversion data and sales feedback.
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-product prompts, and lifecycle touchpoints.
Document learnings and share them broadly so the team compounds on what works.
Audience Intelligence Use product usage data, behavioral signals, and tools like Dreamdata and Common Room to build a nuanced understanding of who our most engaged users are and what they do before converting.
Partner with Lifecycle to develop segmented nurture paths for non-converting free users based on persona, usage pattern, and intent.
Reporting & Measurement PLG Metrics (Self-Serve Motion) Own AARRR funnel reporting across the self-serve motion: awareness, acquisition, activation, retention, and revenue.
Core metrics include free signups, activation rate, feature adoption, free-to-paid conversion, and marketing-sourced pipeline from product-led motions. This is the primary ownership of the Growth Marketer in partnership with Product.
PLS Signals (Sales-Assist Motion) In close partnership with Lifecycle Marketing and MOPs, define and monitor the product signals that indicate a user is ready for sales engagement as a Product Qualified Lead for Sales (PLS).
This includes establishing the behavioral thresholds, usage patterns, and intent signals that trigger a handoff, and continuously refining those criteria based on conversion data and sales feedback.
Shared Reporting Cadence Present PLG funnel performance and PLS signal health to marketing leadership and cross-functional stakeholders on a regular cadence, with clear visibility into where the self-serve motion ends and the sales-assist motion begins.
