Job Analysis:

The Senior Security Engineer role at Klaviyo fundamentally aims to enhance and safeguard the integrity of the company's technological infrastructure across cloud, on-premises, and hybrid environments. This role is designed for an engineer with a versatile security skill set, capable of adapting their expertise—whether in cloud security, identity and access management, secure design, or data protection—to meet evolving security threats and operational demands. The candidate will be tasked with designing and implementing scalable security controls, conducting deep threat modeling, risk assessments, and architecture reviews, and automating security enforcement through infrastructure-as-code. Collaboration is key, as the engineer must integrate security practices seamlessly into cross-functional teams spanning development, IT, and operations, while championing best practices and ongoing innovation. Technically, the role demands fluency in modern cloud platforms such as AWS, GCP, or Azure, proficiency with automation tools like Terraform or CloudFormation, and a strong foundation in secure systems design and vulnerability management. Soft skills—especially the ability to communicate complex security concepts to both technical teams and non-technical stakeholders—are equally critical. The successful candidate must be comfortable handling ambiguity, prioritizing effectively in a broad and dynamic scope, and leading security initiatives that elevate the company’s security posture enterprise-wide. Initial success would likely be measured by the candidate’s impact on risk reduction, ability to embed secure-by-default architectures, and the adoption of innovative security standards and automation within the organization within the first year.

Company Analysis:

Klaviyo operates as the sole CRM platform dedicated exclusively to B2C brands, positioning itself at the nexus of marketing automation, data analytics, and customer experience. Recognized for empowering prominent relationship-driven brands, it is a fast-growing and innovation-focused company leveraging AI insights and a unified data platform to redefine customer engagement at scale. This strategic positioning means the Senior Security Engineer is entering a high-velocity environment where security isn’t just about protection but enabling seamless, trustworthy customer experiences and data-driven marketing operations. The culture, implicitly communicated, values inclusivity, collaboration, and creativity, welcoming diverse perspectives and encouraging employees to contribute their unique skills toward the company's north star: delighting customers. Such values suggest the role expects initiative, continuous learning, and proactive security advocacy. Within the organizational context, the engineer will be part of the Infrastructure Security Team and likely serve as a cross-functional influencer rather than a narrowly siloed expert. Given the company’s rapid growth and significant reliance on cloud and data platforms, the role aligns strategically with Klaviyo’s long-term goal of scaling securely while innovating, meaning the engineer’s work directly supports business expansion and customer trust. Overall, this is a role for someone who thrives in dynamic environments, values collaboration across diverse teams, and seeks to be a security thought leader within a forward-thinking tech company.
