## About the Role

the modern era? Let's talk. What Makes You a Great Fit - 3+ years of hands-on experience in security research, mobile security, browser research, fraud research, detection research, reverse engineering, or a related technical role. - Experience with web browsers, mobile browsers, WebViews, browser APIs, JavaScript runtime behavior, browser automation, fingerprinting, client-side web security, and low-level browser technologies. - Familiarity with the architecture or codebase of modern open-source browsers and rendering engines, such as Chromium, WebKit, Blink, or Gecko, with the ability to reason about how browser internals can expose new security and fraud signals. - Experience with native Android and/or iOS applications, mobile OS behavior, app instrumentation, emulators, device spoofing, mobile automation, mobile security, and low-level platform APIs. - Attacker mindset and practical understanding of how malicious actors attempt to bypass detection using
automation, AI agents, spoofing, and anti-detection techniques. - Ability to identify subtle technical signals and turn them into practical detection or data collection opportunities. - Experience designing technical experiments and validating research hypotheses. - Experience with one or more SDK development languages and environments, such as TypeScript/JavaScript for web, Kotlin/Java for Android, or Swift/Objective-C for iOS, with the ability to understand implementation constraints and collaborate effectively with SDK engineering teams. - Scripting ability, preferably in Python, for building research tools, automation, and analysis workflows. - Ability to work independently on ambiguous problems and communicate findings clearly to engineering, product, and research stakeholders. Advantages - Experience with Web SDKs, Mobile SDKs, client-side telemetry, device intelligence, behavioral signals, AI agent detection, or fraud detection products. - Experience
researching bots, credential stuffing, scraping, headless browsers, AI-assisted automation, app cloning, SDK abuse, phishing kits, malware, or anti-detection frameworks. - Experience with reverse engineering Android or iOS applications. - Familiarity with detection quality measurement, feature evaluation, false-positive analysis, production monitoring, or machine learning concepts. - Bachelor's degree in Computer Science, Cybersecurity, Data Science, or a related field-or equivalent hands-on experience. Your Day-to-day In This Position - Research browser, WebView, Android, and iOS environments from an attacker's perspective. - Identify new security signals, behavioral indicators, and technical patterns that can improve fraud, abuse, automation, and AI
