About the role

Key responsibilities & impact

Reverse-engineer the hardest antibot and fingerprinting systems on the web across JS VMs, WASM, and polymorphic/obfuscated code
Build JS function tracing, deobfuscation pipelines, and fingerprint-inspection tooling to automate reverse-engineering investigations
Use LLMs, agents, and custom automation to deobfuscate, classify, and diagnose detection surfaces
Build and maintain website intelligence pipelines with checkpointed history and baseline-diffing capabilities
Feed AI reverse-engineering and ban-resolution systems the context, signals, and structured intelligence needed to resolve cases autonomously
Codify reverse-engineering wins into durable tools, rules, and pipelines for engineers and AI agents
Integrate tooling into the custom browser and automation stack
Mentor others in AI-augmented reverse-engineering techniques

Requirements

What you’ll need

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: Experience with reverse-engineering tools like IDA, Ghidra, Frida, or Babel
Bonus: Experience building tooling or pipelines that feed machine-learning or AI systems
Bonus: Experience with C/C++ and Rust
Bonus: Core contributions to Mozilla or Chromium projects
