About the role

Casco is building autonomous security testing for web apps, APIs, cloud, and AI systems. The role focuses on developing AI-driven agent systems for autonomous security testing within a startup environment.

Responsibilities

  • Build agent systems: Design and implement autonomous agents that conduct security assessments. If you've built agents before, you know how wild this space can be
  • Ship with autonomy: Own features from conception to production without someone looking over your shoulder
  • Make smart tradeoffs: Balance speed and scalability in a startup environment where perfect is the enemy of shipped
  • Collaborate cross-functionally: Work directly with security engineers and customers to turn ambitious ideas into reality
  • Write TypeScript without any: Build robust, maintainable systems that can handle the chaos of autonomous security testing
  • Learn security on the fly: You don't need to be a security expert, but you should be pumped about learning how hackers think
  • Communicate clearly: Explain complex technical decisions to teammates and write documentation that actually helps

Qualifications

  • Strong TypeScript experience: You know the language deeply and can architect complex systems with it
  • Agent building experience: You've built autonomous systems, agents, or similar "smart" software that makes decisions independently
  • Cloud native experience: You've built on cloud services and know distributed systems
  • Security-minded: You have basic understanding of cybersecurity concepts (or genuine excitement to learn them)
  • Self-directed execution: You see problems and fix them without waiting for permission or detailed instructions
  • Collaborative mindset: You actively seek input from others and make the team better
  • Excellent communication: You write clearly, explain complex ideas simply, and aren't afraid to overcommunicate
  • Startup-ready: You thrive in ambiguity, make decisions with incomplete information, and adapt quickly
  • AI optimism: You believe AI will fundamentally change software and want to be part of making that happen

About Casco

Autonomous security testing for AI systems

Casco helps companies confidently ship AI agents and apps by simulating attacks on their AI systems, identifying vulnerabilities, and providing guided remediation. Companies building on AI face a disproportionate amount of cybersecurity threats. 73% of enterprises experienced at least one AI-related security incident in the past 12 months, with the average incident cost amounting to $4.8m. It also takes 40% longer for these companies to identify and address these breaches vs. non-AI related incidents.
