About The Position

Gradial is building an AI-native system of work for enterprise marketing, using agents to execute campaigns across existing enterprise tools, teams, and workflows. As its first dedicated security engineer, the Staff Security Engineer, Product & Platform will own product and platform security end to end and shape how secure agentic systems are designed, built, and operated as the company scales. This is a hands-on Staff individual-contributor role with responsibility for setting technical security direction, building key systems and controls, and partnering closely with engineering. The role works alongside the IT and compliance lead, who owns GRC and corporate IT, and has significant autonomy to prioritize security investments.

The position covers security strategy, threat modeling and protections for the agentic platform, application and cloud infrastructure hardening, secure-by-default engineering patterns, platform detection and incident response, and technical security discussions with enterprise customers. It also owns technical controls supporting SOC 2 in partnership with the IT and compliance lead and helps identify future security capabilities and recruit additional security team members.

The annual salary range is $220,000–$265,000, with final compensation based on experience, skills, and qualifications. Gradial describes its environment as fast-paced and high-growth, and offers flexible work hours and a collaborative culture focused on learning and impact.
