Get to Know Us
Horizon
3.ai is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. Node Zero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises.
It is used by IT Ops/Sec Ops teams, consulting pentesters, and MSSPs and MSPs.
We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We’re committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, “checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.
What You’ll Do
We’re looking for an Attack Engineer with deep Oracle Cloud Infrastructure (OCI) expertise to help build the next generation of cloud attack capabilities within Node Zero.
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, Azure, and GCP, 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 Node Zero Attack team and take ownership of building OCI attack content from the ground up. You’ll research Oracle cloud services, identify attack paths and misconfigurations, develop offensive capabilities, and help shape how Node Zero assesses Oracle Cloud environments at scale.
This is not a maintenance role. You’ll be helping define Horizon
3.ai’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
Research Oracle Cloud Infrastructure services and identify offensive security opportunities across the platform.
Develop new attack techniques, attack paths, and security assessments targeting OCI environments.
Build and maintain production-quality Python code that powers Node Zero attack capabilities.
Conduct offensive security research against OCI compute, networking, storage, databases, IAM, Kubernetes, and cloud-native services.
Analyze real-world OCI deployments to identify common attack vectors and customer risk patterns.
Collaborate closely with software engineers, attack engineers, and offensive security SMEs to bring new capabilities into production.
Document research findings, attack methodologies, and technical design decisions.
Help prioritize future OCI attack coverage based on customer demand and emerging threats.
Contribute to the technical direction of Node Zero’s cloud attack capabilities.
What You’ll Bring
RequiredHands-on offensive security experience targeting Oracle Cloud Infrastructure (OCI).
Strong understanding of cloud attack paths and cloud-native security concepts.
Experience with web application testing, cloud penetration testing, external assessments, or red team operations.
Experience writing Python code for automation, tooling, or offensive security workflows.
Ability to independently research unfamiliar technologies and rapidly become an expert.
