Company

hirify.global is building an AI-native system of work for enterprise marketing, using agents to execute campaigns across existing tools, teams, and workflows.

What you will do

• Define and drive product and platform security strategy, prioritizing investments against the most important risks.
• Lead threat modeling for the agentic platform and design protections for agent behavior, permissions, isolation, customer data, and platform boundaries.
• Harden production application and cloud infrastructure, including access controls, IAM, secrets management, and the CI/CD supply chain.
• Build secure-by-default patterns with engineering teams for agents, services, and infrastructure.
• Own security detection and incident response, including logging standards, detection coverage, and response processes.
• Represent technical security in enterprise customer reviews, architecture discussions, and SOC 2 control implementation.

Requirements

• 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.
• Strong technical perspective on securing LLM and agent-based systems, with the ability to reason about emerging risks from first principles.
• Experience leading security incident response for production services and improving systems based on findings.
• Track record of writing and shipping production code, security tooling, or infrastructure rather than only reviewing others’ work.
• Strong judgment and comfort making pragmatic security tradeoffs in fast-moving environments without an established playbook.
• Clear communication with engineers, company leadership, and enterprise customer security teams.

Nice to have

• Experience as an early security hire at a high-growth B2B SaaS, AI, or infrastructure company.
• Experience building security detections, telemetry, and logging pipelines in cloud environments.
• Experience implementing technical controls for SOC 2 or ISO 27001, or contributing to AI security research, standards, or open-source security tooling.

Culture & Benefits

• Performance-based annual bonus and meaningful equity awards.
• Medical, dental, and vision coverage; employee coverage is fully covered and dependent coverage is 75%.
• Fertility and family-planning support, 401(k) plan, and unlimited PTO.
• Seattle office with a gym, sauna, bike parking, and free lunch three days per week.
• Flexible work hours, collaborative culture, learning opportunities, and a fast-paced environment focused on ownership and impact.
