An exciting opportunity within the Security Trust and Risk (STAR) team whose mission is to ensure the safety and security of our customers, partners and Klaviyos as well as deliver best in class technology solutions, infrastructure and services. This is achieved by providing a robust and secure technology foundation to do great work. We solve problems using technology, embrace automation and AI, and support Klaviyo's continued scalability and sustainable employee growth in a rapidly evolving environment. The STAR team assists the Global Security Services (GSS) organization in developing and refining information security policies, standards and strategy, enterprise risk management, creating metrics and reporting, coordinating cross-functional projects, and strategically aligning global information security initiatives with the broader CISO vision amongst other governance, risk and compliance efforts. The STAR team is highly collaborative and cross-functional, working closely with various functions within the GSS team (namely Security Product and Development and Security Intelligence Operations), Global Technology Solutions (GTS) team and the broader Klaviyo organization. About the role: The Lead Security Governance & Risk Engineer is a senior, hands-on role at the point where security governance meets risk engineering. You will own the parts of the risk programme that turn policy and standards into measured, monitored, and automated risk decisions. Reporting to the Senior Manager, Security Risk Engineering and operating as a second line of defense, you will run the technology and third-party risk register, lead AI risk governance and ISO 42001 readiness, and build the automation that gives Klaviyo a continuously updated, quantified view of its risk posture. You will work alongside the Trust and Compliance team who are the custodians of our security policies and standards, making sure each one connects to a specific risk it reduces and is enforced through operational controls rather than living as a document. You will partner closely with Engineering, Product, GTS, Legal, Internal Audit, the ARIA team, and Finance to make risk legible across the business, and you will challenge first-line teams credibly while keeping your independence. This is a role for an engineer who thinks like a risk professional: someone who automates repeatable assessment, instruments controls, quantifies risk in financial terms, and treats AI as foundational infrastructure rather than an afterthought. ​​ How you’ll have an impact: • Operate and maintain the risk register and taxonomy. Run the technology and third-party risk register on a consistent standard (threat actor, technique, scenario, safeguard, loss event, quantification) so that risks aggregate, prioritise, and report meaningfully across the business. • Lead AI risk governance and ISO 42001 readiness. Maintain the AI risk assessment methodology and risk criteria, maintain the consolidated AI risk register against the K:AI inventory, and define AI risk treatment plans that map each risk to specific controls and treatment decisions. Drive ISO/IEC 42001 readiness (Clauses 6.1 and 8.2/8.3) toward the certification target, working with the Trust & Compliance and ARIA teams. •
