## Description

We're looking for an Attack Engineer with Oracle Cloud Infrastructure (OCI) expertise to help build the next generation of cloud attack capabilities within NodeZero.

This is a highly strategic role. As OCI adoption continues to grow among large enterprises, government organizations, and AI-focused infrastructure providers, our customers are increasingly asking for deeper OCI coverage. We already support AWS and Azure, and we're making a significant investment in OCI as the platform continues to gain traction among hyperscale customers and critical enterprise environments.

You'll join our NodeZero Attack team and join a team of engineers building OCI attack content from the ground up. You'll research Oracle Cloud services, identify attack paths and misconfigurations, develop offensive capabilities, and help develop how NodeZero assesses Oracle Cloud environments at scale.

This is not a maintenance role. You'll serve as an attack engineer implementing Horizon3's OCI offensive security strategy and will have a first-hand influence on how OCI attacks are integrated into the platform.

What You'll Do

 * Conduct research into OCI attack paths, identity and trust relationships, service misconfigurations, and emerging attacker techniques.
 * Design, implement, and validate production-quality Python attack capabilities spanning OCI IAM, service accounts and workload identities, compute, Kubernetes/OKE, storage, databases, secrets, networking, and other cloud-native services.
 * Chain individual weaknesses into realistic attack paths, with reliable proof of exploitability and clear, actionable customer outcomes.
 * Build and maintain safe, repeatable attack logic and supporting tests; investigate failures and improve reliability, precision, and maintainability.
 * Collaborate closely with software engineers, attack engineers, and offensive security SMEs to bring new capabilities into production.
 * Practice rigorous software development practices to implement OCI-based attack paths based on direction from the technical lead and team manager.
