Growth Engineer Intern

We are not a theoretical security company. Our team has responsibly disclosed real, high-severity vulnerabilities to well-known technology companies, and our findings are the front door to most of our customer relationships. You'll sit between product, engineering, and distribution. One day you might ship an interactive security tool that brings in qualified leads. The next, you'll rebuild an onboarding step, automate a research workflow, or turn a customer conversation into a launch. This is an engineering role with a growth target. You'll write code and copy, talk to users, instrument what you ship, and know whether it worked. What you'll do Build growth surfaces from start to finish: landing pages, free tools, product-led loops, onboarding experiments, and internal automation Run a tight experiment cadence.
