About The Role As Comet continues to grow as a stand‑alone product and codebase, we are seeking a Browser Security Engineer to lead and own browser‑specific security initiatives, including custom Chromium development, extension security, and cross‑device features.
What You’ll Do
Lead threat modeling and security architecture reviews for all Comet browser surfaces.
Collaborate closely with product and engineering teams to proactively identify and mitigate browser vulnerabilities, especially issues specific to custom Chrome engineering and browser extension architecture.
Develop security best practices, tooling, and documentation for engineers building browser‑facing features.
Serve as the security expert for topics such as Same‑Origin Policy (SOP), XSS, sandboxing, browser extension permissions, and secure inter‑device communication.
Triage and resolve vulnerabilities found by external researchers (e.g., bug bounty, red‑teaming partners) and the Chromium community.
Build strong relationships with security partners and leverage their feedback for continuous improvement.
Stay up to date on emerging browser security threats, tools, and industry trends.
What We're Looking For
Prior experience in browser, application, or product security (ideally with Chrome/Chromium or other browser engine experience).
Deep knowledge of modern browser architectures; understanding of XSS, CSP, sandboxing, extension security, and WebView‑specific threats.
Experience with security reviews and threat modeling for web, mobile, and extension platforms.
Ability to work cross‑functionally with engineers, product leads, and external security researchers.
Nice to Have
Contributions to open‑source browser projects, security research, or participation in bug bounty programs.
Experience with web and mobile threat modeling.
Familiarity with secure sync and cross‑device communication mechanisms.
Track record of proactive security work embedded within product teams.
Why Join Us
Shape security strategy for a next‑generation browser product.
Work on challenging problems at the intersection of custom Chromium engineering, browser extensions, and mobile security.
