Island is seeking a Senior Security Researcher to join its dedicated security research team, which identifies and mitigates threats across the browser, network, and endpoint landscape. The research directly shapes Island's enterprise platform security capabilities, from detection logic to protective controls.
The role operates with a purple team mindset—thinking like attackers to build superior defenses. You will own the complete cycle: discovering novel vulnerabilities and attack techniques, then designing and implementing product-level detections and mitigations to neutralize them.
Key responsibilities include:
- Offensive Research: Discover new attack vectors, abuse patterns, and security gaps in browsers, web applications, OS internals, and enterprise workflows.
- Defensive Engineering: Design and implement detections, mitigations, and security policies informed by offensive findings; close the loop from attack to protection.
- Vulnerability & Malware Analysis: Perform reverse engineering on malware, exploits, and obfuscated code across Windows, macOS, and browser environments.
- Web & Browser Security: Research techniques ranging from classic vulnerabilities (XSS, SSRF) to browser-specific primitives (extension abuse, DOM manipulation, same-origin bypasses).
- Supply-Chain Security: Investigate threats in software supply chains, including browser extension marketplaces and package registries.
- Threat Intelligence: Correlate signals across multiple sources to identify malicious infrastructure and adversary TTPs.
- Public Impact: Write technical blog posts, publish research, and represent Island at major security conferences (Black Hat, DEF CON, etc.).
Island's Enterprise Platform unifies AI enablement, network access, data protection, identity, and endpoint control into one coherent workspace. The company is backed by top-tier investors including Coatue Management, Insight Partners, and Sequoia Capital, and is trusted by some of the largest enterprises globally.
