Job Summary

Build and automate reverse-engineering workflows to defeat antibot and fingerprinting systems. You’ll develop JS/VM and WASM tracing, deobfuscation, and fingerprint-inspection tooling, then use LLMs and agentic automation to classify detection surfaces and rapidly ship reusable capabilities. Maintain website intel pipelines with diffing against known baselines, feed structured intelligence to AI systems, and collaborate across engineering and tooling stacks.
