📋 Description

• Reverse-engineer the hardest antibot and fingerprinting systems on the web, across JS VMs, WASM, and polymorphic/obfuscated code. • Build the JS function tracing, deobfuscation pipelines, and fingerprint-inspection tooling that turn manual reverse-engineering investigations into fast, repeatable, largely automated workflows. • Use AI aggressively — LLMs, agents, and custom automation — to deobfuscate, classify, and diagnose detection surfaces, and to rapidly prototype and ship tooling that previously would have taken weeks. • Build and maintain website intel pipelines with checkpointed history, so that when an antibot ships an update we diff against a known-good baseline instead of rediscovering the problem from scratch. • Feed our AI reverse-engineering and ban-resolution systems the context, signals, and structured intelligence they need to autonomously resolve the majority of cases. • Codify one-off reverse-engineering wins into durable capability — tools, rules, and pipelines usable by other engineers and by AI agents alike. • Collaborate across engineering to fold your tooling into the custom browser and automation stack, and mentor others in AI-augmented reverse-engineering technique.

🎯 Requirements

• A hacker mindset — able to rapidly develop proof-of-concepts and working tools to get to a result, and comfortable with the inherent uncertainty and open-endedness of the work. • Demonstrated use of AI tooling (LLMs, coding agents, automation) to accelerate your own engineering, with a strong instinct for what to automate and when. • Strong proficiency in JavaScript/Node.js and Python, with a broad programming background and exceptional problem-solving ability. • Strong research, debugging, fuzzing, and reverse-engineering skills, including static, dynamic, and concolic analysis. • Hands-on experience reversing JavaScript VMs, WASM, and heavily obfuscated or polymorphic code. • A deep understanding of operating systems and computer networking concepts. • Adept with tools such as Wireshark, Burp Suite, and similar for intercepting and debugging network traffic. • Understanding of browser engines, browser fingerprinting, and antibot/anti-scraping mechanisms. • Approach prioritization logically and with a measurement-backed strategy, and thrive in a collaborative environment. • Bonus points for • Experience with reverse-engineering tools like IDA, Ghidra, Frida, or Babel. • Experience building tooling or pipelines that feed machine-learning or AI systems. • Experience with C/C++ and Rust. • Core contributions to Mozilla or Chromium projects.

🏖️ Benefits

• Become part of a self-motivated, progressive, multi-cultural team • Have the freedom and flexibility to work from where you do your best work • Attend conferences and meet with team members from across the globe • Work with cutting-edge open source technologies and tools
