Requirements

  • 5+ years of software engineering or application security experience, with meaningful hands-on AppSec depth in modern SaaS environments.
  • Strong software development skills and the ability to read, write, and ship production code; Ruby experience is highly valuable, and Python or similar scripting ability is a plus.

  • Deep familiarity with common AppSec issues, secure design, secure authentication and authorization patterns, vulnerability management, and developer security tooling.
  • Demonstrated ability to perform deep code review, penetration testing, and exploit-oriented validation, and to either fix vulnerabilities directly or work closely with engineers to land durable remediations that hold up…
  • Experience handling findings from bug bounty, pentests, internal reviews, or automated security tooling through closure and verification.
  • Experience using AI-assisted tools, automations, APIs, or structured workflows to improve engineering or security processes at scale.
  • Experience securing AI-powered systems or features, including AI API exposure, prompt and response handling, data protection, misuse scenarios, and monitoring expectations.
