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.
