About Glean:

Glean is the Work AI platform that helps everyone work smarter with AI. What began as the industry’s most advanced enterprise search has evolved into a full-scale Work AI ecosystem, powering intelligent Search, an AI Assistant, and scalable AI agents on one secure, open platform. With over 100 enterprise SaaS connectors, flexible LLM choice, and robust APIs, Glean gives organizations the infrastructure to govern, scale, and customize AI across their entire business - without vendor lock-in or costly implementation cycles.

At its core, Glean is redefining how enterprises find, use, and act on knowledge. Its Enterprise Graph and Personal Knowledge Graph map the relationships between people, content, and activity, delivering deeply personalized, context-aware responses for every employee. This foundation powers Glean’s agentic capabilities - AI agents that automate real work across teams by accessing the industry’s broadest range of data: enterprise and world, structured and unstructured, historical and real-time. The result: measurable business impact through faster onboarding, hours of productivity gained each week, and smarter, safer decisions at every level.

Recognized by Fast Company as one of the World’s Most Innovative Companies (Top 10, 2025), by CNBC’s Disruptor 50, Bloomberg’s AI Startups to Watch (2026), Forbes AI 50, and Gartner’s Tech Innovators in Agentic AI, Glean continues to accelerate its global impact. With customers across 50+ industries and 1,000+ employees in more than 25 countries, we’re helping the world’s largest organizations make every employee AI-fluent, and turning the superintelligent enterprise from concept into reality.

If you’re excited to shape how the world works, you’ll help build systems used daily across Microsoft Teams, Zoom, ServiceNow, Zendesk, GitHub, and many more - deeply embedded where people get things done. You’ll ship agentic capabilities on an open, extensible stack, with the craft and care required for enterprise trust, as we bring Work AI to every employee, in every company.  About the Role:   Glean is seeking a Field CSO to serve as Glean’s executive, customer‑facing security leader for prospects and customers. You will build trust with CISOs, CIOs, Chief Risk/Privacy Officers, and security architects by translating Glean’s security and AI governance model into their business, regulatory, and technical context. You’ll advise on secure deployments, accelerate security reviews (DPIAs/PIAs, vendor assessments), help remove risk blockers in complex deals, and become the voice of the field back to Product, Security, Legal, and GTM. This role is not our corporate CISO. It is an external‑facing, executive advisor role aimed at helping customers successfully operationalize Glean securely and at scale.
You will:

• Act as the primary executive security advisor for named strategic accounts, partnering with Sales, SE, and CS to shape security strategy, deployment patterns, and program design for Glean’s Work AI platform.
• Lead and expedite security due diligence: DPIAs/PIAs, vendor risk assessments, data flow documentation, LLM‑related risk mitigations, and control mapping to frameworks (e.g., SOC 2, ISO 27001, HIPAA, GDPR, FedRAMP‑adjacent asks, TX‑RAMP).
• Build compelling risk narratives and decision memos for C‑suite and Boards that connect security, privacy, and compliance outcomes to measurable business value and adoption.
• Serve as an executive “title match” in late‑stage cycles; join roadmap and architecture reviews to clear risk blockers and accelerate time‑to‑value.
• Security strategy, enablement, and thought leadership
• Publish and present Glean’s AI security and governance point of view (talks, webinars, whitepapers, playbooks), with pragmatic guidance on topics like single‑tenant SaaS, customer‑hosted deployments, data residency, encryption and key management, permissions mirroring, and agent guardrails.
• Develop reusable artifacts 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, red‑teaming, prompt‑injection defenses, allow/deny model policies).
• Customer outcomes and governance
• Co‑design adoption and governance programs with customer security, IT, data, and privacy teams, including role‑based access, retention, redaction, secrets and PII controls, and ongoing audit practices.
• Advise on AI g
