About The Position

At Klaviyo, we're on a mission to empower creators to own their destiny. Our AI-first B2C CRM platform empowers 176,000+ brands in 80+ countries to cultivate relationships with hundreds of millions of consumers. We love solving hard problems and look for people who specialize in certain areas while being passionate about building, owning, and scaling solutions end-to-end, overcoming any obstacle in their way. We are a team of ambitious, customer-obsessed peers who are insatiably curious and meticulous in our craft. We push each other to grow beyond our comfort zone, learn new things, and work hard to ensure each day is better than the last. As a Lead Security Trust & Compliance Engineer at Klaviyo, you'll be the primary owner of two or more of our Trust & Compliance programs — compliance operations & audits, continuous control monitoring, security policies & standards, security education & awareness, and customer trust operations among them. You'll set the strategy for the programs you own, run our audits end to end, engineer the controls and evidence pipelines that make them sustainable, and raise the technical bar for the practitioners around you. You won't have direct reports, but you will tactically lead the team on your programs: delegating work, setting teammates up to succeed, and mentoring analysts on their technical growth and career goals. This is your opportunity to take a leading role in cybersecurity, applying and deepening your expertise in security automation, risk analysis, control design, audit management, modern SaaS platform architectures, and many domains of information security (just about all of them!)

Requirements

In-depth understanding of multiple security and privacy frameworks — such as NIST CSF 2.0, CIS Critical Security Controls, CSA STAR, ISO 27001, ISO 27002, ISO 27017, ISO 27018, ISO 27701, ISO 42001, SOC 1, SOC 2, PCI, HIPAA, SOX ITGCs, GDPR, CCPA, and CPRA — including the ability to identify gaps against a framework that is new to the organization, define the strategy, and execute the implementation
A track record of personally owning security and privacy compliance audit programs end to end, including acting as the primary interface to internal and external auditors through scoping, walkthroughs, and findings resolution
Experience writing policies and standards that are precise enough to test and clear enough for engineers to follow, including ownership of the review and exception processes around them
Deep experience designing, assessing, and continuously monitoring modern security and privacy controls, including determining control design for net-new controls and diagnosing deficiencies from system configurations, technical documentation, security tool data, and application code
Experience with GRC engineering and security automation in general, especially applying AI and automation to eliminate toil
Knowledge of various enterprise SaaS applications, cloud infrastructure such as AWS and Kubernetes, modern software engineering practices/tools, databases, operating systems, secure network design, and other technology relevant to cybersecurity
Experience owning programs against defined KPIs and SLAs, including setting quarterly strategy, planning the work, and reporting on progress
A track record of mentoring practitioners, delegating effectively, and driving technical direction without formal authority
Excellent interpersonal and communication skills and the ability to form relationships with internal and external teams.
Excellent verbal and written communication
Strong alignment with Klaviyo’s core values

Nice To Haves

Familiarity with modern compliance automation or trust management platforms (Drata, Vanta, Anecdotes, HyperProof, etc.)
Experience with SQL, building tools with REST APIs, and Python
Infrastructure-as-code or policy-as-code experience (Terraform, OPA/Rego, Conftest)
Building with agentic AI tooling (MCP, agent skills, evals and guardrails) and/or governing AI controls against ISO 42001 or NIST AI RMF
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
Relevant certifications, such as CISA, CISSP, or CCSP

Responsibilities

Own internal and external audits and examinations end to end from scoping and readiness through fieldwork and evidence delivery; act as our primary point of contact for auditors and assessors, and develop action plans to correct findings and exceptions
Identify gaps against frameworks we do not yet meet, define the strategy to close them, and drive the implementation when Klaviyo takes on a new certification or regulation
Own security policies and standards end to end — author and maintain the policy, standard, and procedure hierarchy, decompose standards into testable requirements mapped to frameworks, and run the review, ratification, and exception management
Determine control design and implementation details for net-new controls, provide technical guidance to partner teams on control design best practices, and diagnose deficiencies by reviewing system configurations, technical documentation, security tool data, and occasionally application code
Define control health metrics and build the pipelines behind them from the systems we already run, so control health is a live signal rather than a quarterly assertion
Automate and streamline our Security Trust & Compliance workflows — control testing, continuous control monitoring, evidence collection, identity governance, and security Q&As for employees and customers — with a penchant for creating excellent self-service experiences, and define new approaches, systems, and tools for the team where none exist yet
Proactively identify internal and external risks and opportunities relevant to our Trust & Compliance programs, and propose the plans to address them
Ability to effectively prioritize and execute tasks in a high-pressure environment
Solutions oriented mindset
Working collaboratively inside and outside your direct team
