Senior Web Browser Researcher in भारत

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Web Browser Researcher based in India. Join a fully remote, globally distributed team developing advanced device intelligence and fraud-detection technology. As a Senior Web Browser Researcher, you will investigate browser behavior, discover novel identification techniques, and improve the accuracy and stability of core products. You will lead research from initial hypothesis through validation and engineering implementation, turning complex technical discoveries into measurable product improvements. Working at the intersection of JavaScript, browser internals, web security, and networking, you will tackle open-ended challenges that require rigorous experimentation and reverse engineering. You will also develop automated research tools, anticipate browser platform changes, and collaborate closely with product and engineering teams. This role offers the opportunity to shape cutting-edge technology, mentor peers, and contribute to the broader research community. Accountabilities: You will lead independent technical research into browser behavior and identification techniques, ensuring that discoveries are validated, actionable, and translated into meaningful improvements across device intelligence and fraud detection. - Research novel device-identification, visitor-identification, Smart Signals, and bot-detection techniques across modern web browsers, working effectively with ambiguous or evolving requirements. - Evaluate research findings against real-world constraints, including performance budgets, execution contexts, same-site behavior, proxy implications, and interactions with existing signals. - Design and conduct experiments, analyze supporting data, and deliver clear recommendations with estimated impact, false-positive and false-negative rates, limitations, and trade-offs. - Stay involved throughout implementation by reviewing engineering changes, clarifying research objectives, answering technical questions, and advising on edge cases.

- Build and maintain automated research tooling, including observers, fuzzers, and scrapers, to discover new signals and detect browser platform changes. - Monitor browser beta, canary, and developer channels, as well as technical specifications and RFC discussions, to anticipate changes and assess their potential product impact. - Produce structured research outputs, including internal reports, technical articles, proofs of concept, experimental signal implementations, and supporting analyses. - Collaborate with product and engineering partners to translate complex technical findings into actionable development priorities. - Contribute to the research team's growth through mentorship, peer review, knowledge sharing, and public technical thought leadership. Requirements: You should have deep expertise in web technologies and browser behavior, combined with strong experimental skills and the ability to turn independent research into validated, measurable outcomes. You should be comfortable navigating undocumented technical behavior and communicating complex findings clearly to both technical and product stakeholders. - Deep understanding of web platform fundamentals, browser internals, and web security concepts. - Strong proficiency in JavaScript and the ability to read, understand, and navigate code written in multiple programming languages. - Solid knowledge of web networking fundamentals. - Demonstrated ability to uncover and explain undocumented behavior in web technologies, APIs, and protocols through testing, debugging, and reverse engineering. - Experience independently driving research from an initial idea through experimentation, validation, and actionable recommendations. - Ability to design and execute experiments using real-world traffic and analyze large-scale datasets to validate findings.
