The core challenge is turning real attacker behavior into automated, repeatable systems that scale.

We are looking for a Senior Security Engineer who understands exploitation deeply but prefers building tooling and automation over one‑off research. You will work on systems that:

-
- Automatically generate and validate exploit PoCs for known WordPress / PHP CVEs
- Analyze PHP execution traces from real zero‑day attacks against WordPress installations

LLMs are a first‑class component of this work—not a novelty—used to accelerate exploit reconstruction, PoC generation, and attack workflow automation.

This is an engineering role with offensive depth, not a traditional pentesting or red‑team position.

What You’ll Build

-
- Systems to ingest, normalize, and analyze PHP execution traces:

-
- Function calls, parameters, control flow, side effects
- No native binary reversing—focus is PHP‑level execution and logic
- Too
