Job Description

Responsibilities

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.

Requirements

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

San Francisco based: Work from our SF office.

Equity package with high growth potential
