Product Security Researcher

As a Product Security Researcher at Island, you will dive deep into the security landscape of modern browsers, operating systems, and enterprise applications to discover novel vulnerabilities, evaluate real-world threat scenarios, and help shape our security posture through innovation and hands-on research. You will be instrumental in driving advanced security initiatives that help maintain Island’s position at the cutting edge of secure enterprise computing.

Key Responsibilities:

• Vulnerability Research: Identify and analyze vulnerabilities in browser components, system integrations, and third-party libraries relevant to the Island Enterprise Browser.
• Security Testing & Tooling: Develop custom tooling and automation for security testing, fuzzing, and vulnerability detection tailored to our product stack.
• Threat Modeling: Collaborate with developers, architects, and the Product Security Lead to assess threat scenarios and attack surfaces for new features and integrations.
• Exploit Prototyping: Build proof-of-concepts to validate the impact and exploitability of discovered security issues.
• Collaboration & Knowledge Sharing: Support development teams in secure coding practices, and contribute to internal knowledge bases and playbooks.
  
  

• Strong understanding of browser internals, OS security mechanisms, or application-layer security.
• Proficiency in one or more programming/scripting languages (e.g., Python, JavaScript, C/C++, Go).
• Experience in vulnerability research, bug hunting, reverse engineering, or exploit development.
• Familiarity with common vulnerability classes (e.g., XSS, RCE, memory corruption, sandbox escapes).
• Curiosity-driven mindset with a passion for breaking things and understanding how they work.
• Experience with fuzzing tools, debuggers, or reverse engineering frameworks is a strong plus.
