We are building an engineering‑heavy security platform for protecting WordPress and its plugin ecosystem.

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




This is an engineering role with offensive depth , not a traditional pentesting or red‑team position.
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
Convert CVE descriptions + PHP source code into working PoCs
Exploit mutation and robustness testing
php
WordPress REST APIs
Strong background in security engineering or offensive security automation
Hands‑on experience exploiting WordPress plugins, themes, or PHP applications
PHP execution model and request lifecycle
WordPress internals (nonces, hooks, REST, admin flows)
Proven ability to read, reason about, and exploit PHP source code
Strong Python engineering skills for building:

Analysis tooling
Contributions to exploit tooling, frameworks, or security automation
Manual pentesting or report‑driven consulting
