Growth Engineer

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.

• 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.

• 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.

• 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. We pay above market rate to attract the best and brightest. You included!

• 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

Send your resume to careers@casco.com along with:

• A brief description of a growth experiment you ran. Say what you tested, how you measured it, and what happened
• An example of automation or tooling you built to scale a manual process
• Your take on what makes security engineers hard to market to (and how you would approach it)

Keep it real. We value genuine thoughts over corporate speak.

We are an equal opportunity employer committed to building a diverse and inclusive team.

Must be authorized to work in the United States.
