Staff Security Engineer, AI
About The Position
Gradial is hiring its first dedicated security engineer to own product and platform security end to end as the company scales its AI-native system for enterprise marketing. This is a hands-on Staff individual-contributor role responsible for setting security technical direction, building high-impact systems and controls, and partnering closely with engineering.

The engineer will help secure agentic systems and represent Gradial’s technical security approach to enterprise customers, while contributing to the growth of the future security team.
Requirements
- At least 8 years of security engineering experience, including Principal- or Staff-level ownership across complex production systems.
- Deep product security experience across threat modeling, secure architecture, authentication and authorization, and multi-tenant systems.
- Strong hands-on experience with cloud security, Kubernetes, IAM, and infrastructure as code.
- A strong technical point of view on securing LLM and agent-based systems, with ability to reason about emerging risks from first principles.
- Experience leading security incident response for production services and improving systems based on lessons learned.
- Track record of writing and shipping production code, security tooling, or infrastructure, rather than only reviewing others’ work.

- Clear communication with engineers, company leadership, and enterprise customer security teams.

Responsibilities
- Define and drive product and platform security strategy, prioritizing investments according to the risks that matter most as the company scales.
- Lead threat modeling for the agentic platform and design protections for agent behavior, permissions, isolation, customer data, and platform boundaries.
- Harden application and cloud infrastructure, including production access, IAM, secrets management, and the CI/CD supply chain.
- Partner with engineering to build secure-by-default patterns into the design and delivery of agents, services, and infrastructure.
- Own platform security detection and incident response, including logging standards, detection coverage, and response processes.
- Represent technical security in enterprise customer reviews and architecture discussions, clearly explaining Gradial’s approach to customer security teams.
