About the Role

Glean is seeking a Field CSO to serve as Gleans executive, customerfacing security leader for prospects and customers.

• Security strategy, enablement, and thought leadership.
• Publish and present Gleans AI security and governance point of view (talks, webinars, whitepapers, playbooks), with pragmatic guidance on topics such as singletenant SaaS, customerhosted deployments, data residency, encryption and key management, permissions mirroring, and agent guardrails.
• Develop reusable artefacts for the field: RFP/RFI security templates, reference architectures, policy/control mappings, DPIA/PIA kits, incident communications templates, SIEM export and audit logging guides.
• Partner with Glean Product, Security/Privacy, and Legal on voice of customer for features and policies (e.g., residency, SIEM/audit integrations, data lifecycle, model controls, redteam, promptinjection defences, allow/deny model policies).
• Codesign adoption and governance programmes with customer security, IT, data, and privacy teams, including rolebased access, retention, redaction, secrets and PII controls, and ongoing audit practices.
• Advise on AI governance operating models: risk tiering for use cases, humanintheloop controls, evaluation gates, and production guardrails for agents and workflows.
• Establish success metrics tied to security and business value (e.g., security review cycle time, audit coverage, sensitive data exposure reduction, adoption growth in highrisk teams).
• Partner tightly with Sales Engineering, Customer Success and Support to create repeatable guidance for regulated and complex environments.
• Inform roadmap priorities with fieldvalidated requirements for security posture (e.g., model hub control, connector scopes, data egress minimisation, RBAC/ABAC, audit exports).

About You

• 10+ years in information security with executivelevel customer engagement; former CISO/CSO, Deputy CISO, Security Architect/Strategist, or advisory CISO experience strongly preferred.
• Deep command of enterprise security and cloud/SaaS controls: identity/SSO, leastprivilege, encryption at rest/in transit, key management, audit logging/SIEM, data residency/sovereignty, and thirdparty risk.
• Handson familiarity with major frameworks and regulatory needs: SOC2 TypeII, ISO27001, GDPR/DPAs, HIPAA, and public sector expectations (e.g., TXRAMP; familiarity with FedRAMP requirements helpful).
• Demonstrated experience guiding customers through DPIAs/PIAs, vendor assessments, and contractual security annexes; ability to compress complex risk into clear executive decisions.

• Credible thought leadership (talks, blogs, standards bodies, community contributions) and strong industry network among CISOs and security architects.
• Experience with singletenant SaaS and customerhosted deployment models; background working with GCP/AWS controls, privacy impact assessments, and regional hosting.
• Familiarity with data security posture management, sensitive data detection and remediation programmes, and audit/reporting patterns for enterprise security teams.
