Original job description

Get to Know Us

Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and 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. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.

We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, 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.

About The Role

We're looking for an Attack Engineer with deep Google Cloud Platform (GCP) expertise to help build the next generation of cloud attack capabilities within NodeZero.

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

You'll join our NodeZero Attack team and take ownership of building GCP attack content from the ground up. You'll research Google Cloud services, identify attack paths and misconfigurations, develop offensive capabilities, and help shape how NodeZero assesses Google Cloud environments at scale.

This is not a maintenance role. You'll serve as the technical lead helping define Horizon3 http://Horizon3.ai's GCP offensive security strategy and will have a first-hand influence on how GCP attacks are integrated into the platform.

What You’ll Do

Lead research into GCP attack paths, identity and trust relationships, service misconfigurations, and emerging attacker techniques.
Design, implement, and validate production-quality Python attack capabilities spanning GCP IAM, service accounts and workload identities, compute, Kubernetes/GKE, 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.
Set technical direction for GCP attack coverage: identify gaps, prioritize work with Product and Engineering, and translate research and customer needs into a sequenced roadmap.
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.
Document research findings, attack methodologies, and technical design decisions.
Review designs and code, share domain expertise, and mentor other engineers as they develop GCP attack content.
Contribute to internal enablement and, where appropriate, external research or technical content.

What You’ll Bring

Deep hands-on experience with GCP security and offensive cloud operations, including the ability to reason about IAM permissions, service identities, trust, and resource access.
Expert understanding of cloud attack paths and cloud-native security concepts.
Strong Python engineering skills and experience turning security research or manual techniques into dependable production quality automation or product capabilities.
Passion for building products, not just finding vulnerabilities.
10+ years of professional software engineering and or/ offensive security experience
Experience with cloud penetration testing, red teaming, offensive security research, or building cloud security products.
A record of owning ambiguous technical work, making sound trade-offs, and communicating clearly with technical and non-technical partners.
Strong written communication and a habit of documenting research and design decisions.

What Sets You Apart

Experience with cloud privilege escalation and identity attacks.
Familiarity with AWS, Azure, or OCI offensive security.
Experience integrating security research into production software.
Experience with GKE, Kubernetes, Terraform, gcloud, Google Cloud APIs, or cloud-native CI/CD.
Contributions to security research, open-source projects, conference talks, or vulnerability disclosure.
Experience mapping cloud attack coverage to frameworks such as MITRE ATT&CK for Cloud.
