Senior Manager - Security Risk Engineering

About the role

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. The Senior Manager, Security Risk Engineering is a senior information security and risk leader responsible for evolving risk management at Klaviyo from a traditional, cyber-centric, compliance-driven model into a real-time, business-aligned, engineering-led risk intelligence capability. Reporting into the Director of Security Trust and Risk, you will lead the Security Risk Engineering team as a second line of defense - owning technology risk management, third-party risk, risk quantification, and the risk intelligence and automation capability that turns disparate security signals into a single, decision-enabling view of risk. You will operate as a credible, hands-on risk authority who can challenge and partner with engineering and security teams while maintaining independence from first-line delivery. You will build a team that thinks like risk engineers rather than traditional analysts - automating repeatable assessment, instrumenting controls, and applying AI as foundational infrastructure. You will partner with Engineering, Product, GTS, Legal, Audit, Finance, and the wider GSS organization to make risk legible across the business and to move Klaviyo's risk posture measurably forward. How you'll have an impact: Lead the transition of risk management from a cyber-centric model to an enterprise-wide framework - expanding scope beyond cybersecurity to operational, financial, regulatory, and third-party risk, with integrated remediation tracking and clear ownership of outcomes Own the risk register and taxonomy, establishing a consistent standard (threat actor, technique, scenario, safeguard, loss event, quantification) so that aggregation, prioritisation, and reporting become meaningful Quantify risk in financial terms - expected loss, probability, and cost of remediation versus acceptance - so leadership can make rational investment and risk-acceptance decisions rather than relying on qualitative severity labels Set and continuously refine the risk cadence: weekly risk huddles with business functions, monthly risk reviews, and a quarterly Enterprise Risk Committee, connecting day-to-day execution to GSS and Klaviyo-level objectives Build the risk intelligence and automation capability - partnering closely with the team's risk intelligence lead, whose remit is risk intelligence and building automations using AI - to surface a continuously updated, quantified view of risk posture drawn from the live security tool estate (vulnerability, endpoint, third-party, data movement, and cyber risk quantification sources) Drive the risk scoring programme: integrate third-party risk, application inventory, and cyber risk quantification platforms so that applications and vendors carry a composite, evidence-based risk score that drives tiered, automated decision-making Unlock third-party risk automation through a tiered vendor model - fast-tracking low-risk vendors while ensuring high-risk vendors receive deep due diligence, business reviews, and continuous monitoring Evaluate and govern risks associated with AI/ML deployments, LLM integrations, and cloud data pipelines, embedding AI risk assessment into the internal and third-party risk programs Operate as a second line of defense - providi
