horizon3ai Senior Attack Engineer at horizon3ai develops scalable reconnaissance workflows for external attack surfaces. Focuses on autonomous pentesting by turning manual recon and multi-step attack work into repeatable workflows.
Responsibilities
Design, build, and maintain highly scalable reconnaissance workflows that discover, enumerate, and fingerprint external-facing assets and services in production-grade Python.
Research, explore, and parse large volumes of external-facing data, including unstructured and inconsistent sources, and turn it into accurate, actionable information.
Develop robust approaches to data that is hard to reason about in code, such as free-form banners, web content, documents, and error output, and build parsing and enrichment that holds up across the long tail of real environments.
Collect, store, and connect high volumes of information, and extend our attack-path modeling and graph data model to represent new identity, privilege, and relationship paths.
Traverse identity relationships across the external surface, such as accounts, tenants, SSO and federation, exposed credentials, and third-party services, to find paths from exposure to compromise.
Automate multi-step attack workflows that chain discovery, credential access, initial access, and post-exploitation into complete, safely proven attack paths.
Research emerging external tradecraft and turn it into production attack content, with an emphasis on techniques that still succeed against hardened, well-monitored targets.
Stand up and maintain representative test environments to validate, demonstrate, and regression-test attack scenarios.
Build for production safety and scale: respect target and customer environments, rate limits, and scope while running across very large attack surfaces.
Contribute to priorities and the coverage roadmap based on real customer environments, threat intelligence, and emerging techniques.
Mentor teammates and proactively support their growth, and help define team standards for code quality, research rigor, and operational safety.
Collaborate cross-functionally with engineers, product managers, and customer-facing teams, and author internal documentation and external research and blog posts.
