Sardine
Bot Detection Researcher/Engineer
Job Details
We are hiring a Bot Detection Researcher/Engineer to help us strengthen our detection capabilities across our Web, iOS, and Android SDKs. This role is ideal for someone who enjoys understanding how real devices behave, how automation frameworks operate, and where the differences lie. You will research browser and mobile environments, explore evasion techniques, and uncover new ways to distinguish genuine users from automated or manipulated traffic.
Responsibilities
Analyze how browsers and mobile operating systems expose signals for detecting automation and tampering (spoofing, rooting/jailbreaking). Examine automation frameworks (Playwright, Puppeteer, Selenium, Appium) and mobile instrumentation tools for detection opportunities. Explore OS-level behaviors, sensor patterns, app lifecycle events, Web APIs, and device characteristics to find inconsistencies between real and synthetic environments. Build prototypes/custom test harnesses to validate detection ideas and collect data. Work with engineering teams (Web, iOS, Android, backend) to integrate validated signals into production SDKs. Monitor emerging trends in bot development, mobile emulation, and evasion techniques. Document research and present findings to technical and non-technical audiences.
