Growth Engineer
Date Posted
23 May, 2026
Salary Offered
$180,000 yearly
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.
