Head of IT & Security

About us

OpenZeppelin is the security standard onchain finance is built on. Founded in 2015, our mission is to accelerate the world's transition to an open financial system, built on open standards and secured by rigorous research.

Our open-source Contract Libraries have facilitated over $35 trillion in onchain value and are used by 10 of the top 10 tokenized money market funds and 9 of the top 10 stablecoins by market cap.

We combine AI-native security tooling with deep research and a decade of audit expertise to support leading institutions and crypto-native teams shaping the next generation of digital assets like DTCC, Fidelity, Coinbase, Uniswap, Aave, the Ethereum Foundation, and many more across the full secure development lifecycle.

Please note: Always refer to OpenZeppelin's official job page for the most accurate information about our open roles, as we have seen multiple third party job sites posting inaccurate information.

The IT & Security Team

The Information Security function operates independently under our Legal team and owns everything that keeps the OpenZeppelin organization secure. That means managing our Security, Privacy & IT Program end-to-end: our SOC 2 and ISO 27001 posture, vendor and privacy risk, incident response, our bug bounty programs, and the identity, endpoint, and access systems the whole company depends on. It is also the team our customers meet during security diligence. As our enterprise relationships deepen, increasingly with banks and other regulated institutions, our own program must be as credible as the security we deliver to customers.

Today that program is established and audit-ready. The next chapter is turning it into an enterprise-grade security function that stands up to the scrutiny of the most demanding enterprise customers, partners, and regulators, while safely accelerating our adoption of AI across the company.

What you'll be doing

You will own the strategy, design, and continuous maturation of OpenZeppelin's Information Security Program, and be accountable for managing the team executing it. You can issue-spot security and privacy risks before they materialize, explain the principles behind security and compliance controls to auditors and enterprise security teams, and calibrate our security program proportionate to risk.

IT and infrastructure: Oversee identity and access management, provisioning and onboarding/offboarding, end-user security (MDM, endpoint protection, security training), physical security, disaster recovery, business continuity, and data backup, using automation and AI-powered workflows to make IT and security operations scale faster than headcount.

Strategy, governance and budget: Set the strategic direction, multi-year roadmap, and risk posture of the Information Security Program; deliver on department OKRs; and own the IT and technology budget, with ultimate responsibility for technology procurement.

AI security and governance: Own the secure adoption of AI across the company: evolve our AI governance framework, review and approve AI tools and agentic workflows, and secure our agentic infrastructure (identity, least-privilege tool and data access, secrets handling, monitoring, auditability). Manage frontier model providers as critical vendors, covering security and data-handling diligence, retention and training-use commitments, DPAs and subprocessor flow-downs. Meet emerging obligations such as the EU AI Act, so we can make transparent, defensible commitments to enterprise customers about how our products and internal AI usage handle their data.

Compliance, audit and enterprise trust: Own our audit, certification, and attestation strategy and execution (penetration testing, SOC 2 Type 2, ISO/IEC 27001, successor frameworks) alongside internal security audits; run a third-party and vendor risk management program; and serve as the external face of our security program with customer security teams, regulated financial institutions, and auditors.

Privacy and data governance: Maintain a comprehensive data map of how data flows into, through, and out of the organization, including flows to model providers and through agentic workflows, with data classification, records of processing, and a vendor/subprocessor inventory. Own privacy compliance in partnership with Legal: GDPR, CCPA/CPRA, DPAs and contractual security commitments, and privacy-by-design reviews of new products and features.

Security operations and incident response: Own the incident response program end-to-end, including playbooks, tabletop exercises, post-incident reviews, and breach-notification obligations in partnership with Legal. Manage our bug bounty programs, and partner with development teams to embed security best practices in the SDLC and our software offerings.

You have

10+ years of Security and IT experience, including 3+ years leading a IT Security and GRC function (not solely IT operations) in a high-growth tech company, with demonstrated ownership of strategy, not just execution.

A demonstrated trajectory toward CISO: you have owned a security program end-to-end, presented to executives or boards, and can articulate the "why" behind every control you have implemented.

Experience securing or governing AI/LLM-enabled products or enterprise AI adoption including agentic systems and third-party model-provider risk, with an ability to apply privacy and data-protection laws and practices (e.g., GDPR, CCPA/CPRA) in the AI context.

Nice to have

5+ years working in blockchain or a FinTech with an enterprise client base (e.g., financial services), including navigating rigorous third-party security diligence.
