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.

We’re seeking a highly motivated Senior Security Compliance Engineer to serve as a trusted advisor and hands-on engineer within our Security Trust & Compliance team. You’ll design, build, and optimize automated solutions that streamline compliance operations, strengthen continuous control monitoring, and integrate GRC tooling across Klaviyo’s systems. You’ll partner closely with cross-functional teams, such as Engineering, IT, Security, Legal, Internal Audit, and more. You’ll help Klaviyo scale securely, sustainably deliver more value for our customers, and bolster their trust in us.

As a Senior Security Compliance Engineer, you’ll focus primarily on:

• Compliance operations & audits (for SOC 2, ISO 27001, ISO 27017, PCI, and SOX ITGCs)
• Continuous control monitoring
• GRC automation & tooling (e.g. compliance automation platforms, API integrations, scripted evidence collection and control validation)

• Design, develop, and maintain automated compliance workflows using scripting, APIs, and GRC tooling to streamline evidence collection, control validation, and audit readiness across SOC 2, ISO 27001, ISO 27017, PCI, and SOX ITGCs
• Build and improve continuous control monitoring capabilities that provide real-time visibility into Klaviyo’s compliance posture and proactively surface control gaps
• Partner with the Security Risk team to streamline end-to-end Security Compliance-to-Risk operations, ensuring compliance findings and control observations flow efficiently into risk management workflows
• Implement and customize compliance automation platforms (e.g. Drata, Vanta, Anecdotes) and integrate them with Klaviyo’s internal systems, CI/CD pipelines, and cloud infrastructure
• Serve as a trusted advisor to Engineering and Product teams, embedding compliance-by-design into architecture decisions and helping teams understand and meet security control requirements
• Identify and drive high-value opportunities to use AI and automation to eliminate toil, improve compliance operations, and scale our programs alongside Klaviyo’s growth

• 3–5 years of experience in security compliance, GRC engineering, security engineering, or a closely related field with a strong emphasis on automation and scalable processes
• Understanding of modern cloud-native web application architectures and related security best practices, especially in the context of AWS, Kubernetes, and AI
• Experience implementing and operating Compliance Automation platforms, such as Drata, Vanta, Anecdotes, HyperProof, etc.
• Hands-on experience executing compliance programs for SOC 2, ISO 27001, ISO 27017, PCI, and/or SOX ITGCs
• Proficiency in one or more programming/scripting languages (e.g. Python, Go, SQL) with hands-on experience building automation for compliance workflows, integrating REST APIs, and working with GRC tooling
• Experience applying GRC Engineering principles and values in practice, especially with regard to automation, systems + design thinking, and threat-informed GRC

• A strong bias toward evidence, logic, math, and reason when communicating risk (instead of fear, uncertainty, and doubt)
• A strong bias toward “guardrails, not gates” and “paved security roads” philosophies (instead of rigid “centralized command-and-control” processes and operating styles)
• Excellent ability to plan, prioritize, and deliver results cross-functionally and in a timely fashion
• Proficiency discussing complex, nuanced topics with technical & non-technical audiences alike, especially software engineers
• Strong alignment with Klaviyo’s core values

• Experience implementing Identity Governance tools and processes, such as for user access reviews (UARs) and just-in-time access (JITA)
• Experience working in security operations, security engineering, and/or security architecture roles
• Experience with additional compliance frameworks such as ISO 27018, HIPAA, GDPR, CCPA, or NIS2
