Senior Web Security Researcher

As a Senior Web Security Researcher at Nimble, you will spearhead our efforts in the research domain, driving our cutting-edge data gathering solutions. You will work on complex technical challenges at the intersection of browser internals, reverse engineering, and large-scale data gathering. You will analyze and break down advanced client-side protection mechanisms, dive into large and complex codebases such as Chromium, and develop high-performance, cross-platform capabilities that power our products. This role is both hands-on and research-driven: you’ll be expected to investigate hard problems, turn insights into solutions, and help push the boundaries of what’s possible in web data gathering.

Requirements: • At least 5 years of experience working within research teams, with a focus on at least one of the following: web data extraction, reverse engineering, or browser technologies. • Strong analytical and problem-solving skills, with keen attention to detail and a passion for pushing the boundaries of what’s possible in web data gathering. • Strong JavaScript skills with hands-on reverse-engineering experience in web contexts. Advantages • Hands-on experience with dynamic instrumentation and reverse engineering tools such as Frida, IDA Pro, Ghidra, or Radare2 / Cutter. • Experience with browser automation frameworks (Puppeteer, Playwright, CDP) and/or anti-scraping / bot-detection mechanisms. • Familiarity with web-focused IDEs and debugging environments (e.g., Chrome DevTools Protocol, Charles Proxy, Fiddler, Burp Suite, VS Code, WebStorm). • Prior work with Chromium or Firefox source code.
