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 for fast, repeatable, largely automated workflows.
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.
Feed AI reverse-engineering and ban-resolution systems the context, signals, and structured intelligence needed to resolve cases autonomously.
Codify one-off reverse-engineering wins into reusable tools, rules, and pipelines.
Integrate tooling into Zyte's custom browser and automation stack.
Collaborate across engineering and 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 points for experience with reverse-engineering tools like IDA, Ghidra, Frida, or Babel.
Bonus points for experience building tooling or pipelines that feed machine-learning or AI systems.
Bonus points for experience with C/C++ and Rust.
Bonus points for core contributions to Mozilla or Chromium projects.
