Head of Security (JetBrains Cloud Platform) New

At JetBrains, we are building an AI-native platform for software development that connects developer workflows, team-level collaboration, and organizational control in a single coherent system. Designed to work across teams, tools, and environments, this platform serves as the execution and governance layer for AI-driven development, with security, policy, and auditability built in from day one., We are now looking for a Head of Security to own the security strategy and execution for the agentic platform and its core services (governance, identity, agent execution, integrations, telemetry, and billing surfaces). This is a senior leadership role that combines product security, cloud and platform security, and enterprise trust-building. You will partner closely with product and engineering leaders to ensure we can ship fast while meeting the security expectations of regulated and security-conscious organizations., Platform security engineering and operational readiness

• Build and run an actionable security program, taking responsibility for vulnerability management, security testing, incident response playbooks, on-call interfaces, and secure SDLC practices aligned with the platform's release cadence.
• Define and implement security controls for platform foundations, such as identity and organizational model, integrations, telemetry, billing surfaces, and administrative UX.
• Lead readiness for enterprise security reviews, ensuring security documentation, security posture transparency, and customer-facing security assurance artifacts.

Success criteria:

• Implementation of a repeatable security review process that scales with releases (not dependent on heroics).
• Measurable reduction in critical security risks across the platform's surface.

Customer trust, compliance enablement, and field partnership

• Partner with Sales, Solutions, and Professional Services teams to unblock early design partners and enterprise rollouts with credible security answers and practical mitigations.
• Drive a pragmatic compliance path (with enterprise-grade expectations) that includes security control mapping, audit support, and customer security questionnaires, at speed.
• Act as a security-facing executive in customer conversations when needed.

Success criteria:

• Security becoming an adoption enabler, with fewer blocked deals or PoCs due to security concerns, as well as faster security sign-offs.
• Implementation of a clear enterprise-grade security baseline for the platform that supports scale., * Build and mentor a lean security team (platform security and product security), with strong relationships with infrastructure, identity, and agent runtime teams.
• Implement decision frameworks that clarify what must be centralized vs delegated, when to block vs mitigate, and how to ship securely in an early-stage product environment.
• Establish security KPIs that reflect real risk reduction and adoption readiness (not vanity metrics).

Success criteria:

• A high-trust, high-velocity security organization that product and engineering teams want to partner with.
• Security priorities that are clearly tied to platform milestones and customer adoption.

Do you have experience in Supply chain?, * Senior experience leading platform or product security for a cloud platform, developer tooling platform, or infrastructure product.

• Strong hands-on background in threat modeling, secure architecture, identity and access control, secret management, isolation and sandboxing, and supply chain security.
• Experience building security programs that support enterprise adoption (security reviews, compliance enablement, incident readiness, etc.).
• Comfort operating in early-stage, evolving product contexts, with the ability to define the security system while the product is still being built and help the organization ship with confidence.
