pThis 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 Italy. /p pJoin 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. /p pWorking 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. /p pEsperienza, qualifiche e soft skill: possiede tutti i requisiti per avere successo in questa possibilità? Lo scopra qui sotto. /p h3Accountabilities /h3 ul liResearch novel device-identification, visitor-identification, Smart Signals, and bot-detection techniques across modern web browsers, working effectively with ambiguous or evolving requirements. /li liEvaluate research findings against real-world constraints, including performance budgets, execution contexts, same-site behavior, proxy implications, and interactions with existing signals. /li liDesign and conduct experiments, analyze supporting data, and deliver clear recommendations with estimated impact, false-positive and false-negative rates, limitations,



and trade-offs. /li liStay involved throughout implementation by reviewing engineering changes, clarifying research objectives, answering technical questions, and advising on edge cases. /li liBuild and maintain automated research tooling, including observers, fuzzers, and scrapers, to discover new signals and detect browser platform changes. /li liMonitor browser beta, canary, and developer channels, as well as technical specifications and RFC discussions, to anticipate changes and assess their potential product impact. /li liProduce structured research outputs, including internal reports, technical articles, proofs of concept, experimental signal implementations, and supporting analyses. /li liCollaborate with product and engineering partners to translate complex technical findings into actionable development priorities. /li liContribute to the research team's growth through mentorship, peer review, knowledge sharing, and public technical thought leadership. /li /ul h3Requirements /h3 pYou 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. /p ul liDeep understanding of web platform fundamentals, browser internals,



and web security concepts. /li liStrong proficiency in JavaScript and the ability to read, understand, and navigate code written in multiple programming languages. /li liSolid knowledge of web networking fundamentals. /li liDemonstrated ability to uncover and explain undocumented behavior in web technologies, APIs, and protocols through testing, debugging, and reverse engineering. /li liExperience independently driving research from an initial idea through experimentation, validation, and actionable recommendations. /li liAbility to design and execute experiments using real-world traffic and analyze large-scale datasets to validate findings. /li liRecognized depth in at least one relevant area, such as reverse engineering, network research, or device identification, alongside working knowledge of adjacent fields. /li liStrong written and verbal communication skills, including the ability to explain research outcomes, expected impact, limitations, and trade-offs to engineering and product teams. /li /ul h3Preferred Qualifications /h3 ul liExperience developing research and automation tools, such as scrapers, fuzzers, and observers. /li liHistory of reporting bugs or submitting technical issues to Chromium, Firefox, or WebKit bug trackers. /li liExperience or interest in backend development, particularly Go. /li liFamiliarity with anti-fingerprinting techniques and their implementation across browsers and browser extensions. /li liA public research portfolio, such as conference presentations, technical blog posts, CVEs, or open-source contributions. /li /ul h3Benefits /h3 ul liCompetitive
