About the role
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.
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.
Technology
- Custom computer use stack. - Agentic workflows. - Predominantly TypeScript
Interview Process
- Quick chat with a founder (30 minutes) - We'll talk about your experience with growth engineering and what excites you about this space - Technical discussion (45 minutes) - Walk us through a growth experiment or automation you built and the decisions behind it - Paid work trial (1 week) - Work on a real problem with the team and see if we're a mutual fit
