The Obsidian Security platform gives unified visibility into every human and machine identity, app, and integration across their SaaS estate, detects identity-based and supply chain attacks in real time, and enforces least-privilege access before it's exploited. Trusted by major Fortune 500 companies T-Mobile, Workday, Snowflake, and S&P Global, Obsidian ranked No. 95 on the 2025 Deloitte Technology Fast 500™, growing nearly 1000% from 2021-2024 - helping CISOs turn an unmonitored attack surface into one they can govern with confidence. Obsidian has also been recognized by Forbes as America's Best Startup Employers in 2026.\nIn August 2026, Obsidian raised $85 million in Series D financing led by Crescent Cove Advisors, with participation from existing investors including Greylock Partners, Menlo Ventures, Norwest Venture Partners, IVP, Wing Ventures, and GV - pushing Obsidian's valuation to $1.1 billion, crossing into unicorn status. Obsidian is using the funding to deepen its R&D in agentic AI security and extend its platform as the standard for governing what AI agents can access and do inside third-party applications.\nWith global momentum, a growing partner ecosystem including SentinelOne, Databricks, and Google Cloud, and fresh capital from its Series D behind it, Obsidian is scaling rapidly toward long-term growth and IPO readiness.\nThe Role\nThe CISO will own Obsidian's internal security program end-to-end while serving as a visible security leader to our customers, partners, and the broader market. This role reports to the Chief Legal and Trust Officer.\nResponsibilities\nSecurity Strategy & Executive Communication: Design and execute a global security strategy aligned with business growth objectives. Advise the board and executive leadership on critical cyber risk domains with clear, actionable mitigation plans.\nCyber Risk Management: Own the cyber risk management program, including security risk assessments, third-party vendor reviews, and executive-backed mitigation initiatives targeting measurable risk reduction.\n Security Architecture, Engineering & Operations: Build and lead teams spanning product/application security, infrastructure protection, and security engineering. Oversee threat detection, vulnerability management (with SLA-based performance tracking), and incident response. Establish a guardrail-based controls model for cloud and container workloads.\n Product Security: Embed secure-by-design principles across engineering workflows, integrating security early and consistently throughout the SDLC, including secure coding standards, penetration testing, bug bounty programs, and security requirements for AI/ML components (model integrity, training data protection, prompt injection prevention, output validation).\n AI Security & Governance: Establish enterprise AI governance (acceptable use, data loss prevention for AI inputs, vendor risk assessments for third-party AI services). Build detection and response capabilities for AI-powered attack vectors. Drive adoption of AI and automation across the security function, including AI-assisted threat detection, automated incident response, and intelligent vulnerability prioritization.\nCross-Functional Partnerships: Partner with Engineering and Product to embed security throughout the development lifecycle, AI/ML feature delivery, and infrastructure architecture decisions. Support Sales and TAM teams by participating in customer security reviews, responding to questionnaires, and enabling the team to speak confidently about Obsidian’s security posture. Collaborate with Marketing to develop security-focused content, support thought leadership positioning and inform messaging around trust and security.\nCustomer Trust & External Presence: Serve as the executive-level security contact for prospects and customers during sales cycles, audits, and security reviews. Represent Obsidian in industry forums and public engagements to build market credibility.\nTeam Leadership & Budget: Recruit, mentor, and retain a high-performing security organization. Own the security budget with precise, on-target forecasts.\n M&A Due Diligence: Assess the security posture, risk exposure, and integration readiness of prospective acquisition targets.\nQualifications\n15+ years in information security, with 5+ years in a senior leadership role (CISO, VP/Deputy CISO, Sr. Director of Security, or equivalent).\nDeep experience building and scaling security teams across product security, security architecture, infrastructure protection, and enterprise risk management.\nStrong track record securing cloud-native SaaS environments, including container-based workloads and next-generation security tooling (endpoint protection, CI/CD-integrated code scanning, identity-as-a-service, automated monitoring/remediation).\nExperience developing AI governance frameworks and familiarity with AI/ML attack surfaces (model poisoning, prompt injection, training data extraction, adversarial inputs, ML supply chain risks).\nExperience operating as a customer-facing security executive, including direct participation in sales cycles, regulated entity security reviews, and audits.\nDemonstrated success improving security program maturity using NIST CSF, ISO 27001, or similar frameworks, with measurable results.\nProven ability to present to boards, advise executive leadership, and communicate security posture to customers in support of revenue goals.\nEffective cross-functional partner with legal, compliance, and IT leadership in a matrixed environment.\nExperience managing siginificant security budgets.\nMaster's degree in Information Security, Computer Science, or a related field preferred. Executive leadership education is a plus.\nPreferred\nExperience at a cybersecurity vendor, where the CISO role carries both internal and external credibility demands.\nBackground in critical infrastructure security (energy, utilities, telecommunications) in addition to SaaS/technology.\nHands-on experience deploying AI/ML within security operations (SOAR, AI-assisted threat hunting, automated triage) and familiarity with AI security frameworks (OWASP Top 10 for LLMs, NIST AI RMF, MITRE ATLAS).\nExperience securing AI features within a commercial SaaS product, including red-teaming or adversarial testing of AI/ML systems.\nTrack record conducting security due diligence for M&A transactions.\nExperience engaging government stakeholders or congressional committees on security matters.\nEmployee Benefits\nOur competitive benefits packages are designed to support our employees' well-being, both at work and at home.
