Job title
Growth Engineer
Job location
San Francisco, CA, US
Job description
We are looking for a Growth Engineer to design, build, and scale our growth engine. You will treat growth like a video game, constantly experimenting to get the highest score. You have the technical chops to wire together agents and APIs, the marketing instincts to convert a deeply skeptical security audience, and the AppSec maturity to communicate with credibility. ## **What You'll Do** * **Own the Growth Engine:** Architect and wire the automation layer (APIs, webhooks, LLM agents) that turns product triggers, like a completed pentest, into programmatic upsells. * **Do Things That Don't Scale:** Hustle manually to validate new channels and tactics first. Once a playbook proves it drives high-quality traffic, write the code to automate and scale it indefinitely. * **High-Tempo Experimentation:** Rapidly ship, measure, and iterate on campaigns across HackerNews, Reddit, and LinkedIn to compound user acquisition. * **Technical Chops + Marketing Instincts:** Write the scripts necessary to stitch our systems together, and the copy required to convert security engineers. * **AppSec Maturity:** Move fast and break things in the automation layer, but possess the industry context to never compromise user trust, privacy, or brand reputation. ## **What We're Looking For** ### **Must-Haves** * **Excellent communicator:** Strong writing, researching, and communication skills. You can craft copy that resonates with a technical audience * **Development experience:** Not necessarily in a formal engineering role, but enough to vibecode your own growth automations and stitch systems together * **Technical audience expertise:** Experience targeting security and development teams as customers, or writing for deeply technical audiences * **Campaign experience:** Hands-on experience running email campaigns, GTM campaigns, and sales enablement programs ## **What This Role IS NOT** * **Death by PowerPoint:** You won't be building pitch decks to get committee approval for minor experiments. We bias toward action. * **Brand Bikeshedding:** You won't spend weeks debating font weights or logo placements. * **Vanity Metrics:** We don't celebrate "impressions." We care about pipeline, product usage, and revenue. * **Vendor Management Hell:** You won't spend your days evaluating bloated enterprise marketing software. You'll build leaner, faster systems yourself. ## **What We Offer** * **San Francisco based:** Work from our SF office. * **Competitive Compensation:** * Base salary: $180,000 * Equity package with high growth potential * **Actual Impact:** Your work directly shapes how we acquire and grow our user base. * **Learning Opportunities:** We support your growth with a budget for conferences, books, and tools. * **Smart Colleagues:** Work with a team of ex-AWS engineers and security experts who are genuinely excited about what they build.
