[Hiring] Senior Reverse Engineer @Zyte

Role Description

Reverse engineering is at the heart of how Zyte stays ahead in the banning war. We've cracked some of the hardest antibots on the web — but the ground shifts weekly: antibots ship new sensor formats overnight, obfuscation schemes mutate, and new fingerprinting surfaces appear faster than any team could chase by hand.

This role is not about solving tickets one at a time. It's about building the tools, pipelines, and automation that let both engineers and AI agents solve them at scale. You will be the person who:

• Turns a reverse-engineering breakthrough into reusable tooling.
• Automates the investigation that used to take days into a readout that takes minutes.
• Feeds the intelligence our AI systems learn from.

You'll work at the intersection of deep JS/VM reverse engineering and modern AI-assisted engineering — using LLMs and agentic tooling aggressively to compress the loop between "new detection surface discovered" and "solution shipped."

If you're energized by wielding AI to multiply your own output, by automating away manual toil, and by working on problems where the adversary is smart and the target moves — this is the seat.

Qualifications

• 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.

Requirements

• 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.
