About the team

Klaviyo’s Global IT team — part of Global Technology Solutions (GTS) — powers the systems, tools, and infrastructure that keep the company moving fast. We build automation, platforms, and tooling that enable scalability, security, and employee productivity.

The AI & Dev Ops Engineering team is responsible for delivering the platforms and services that support Klaviyo’s internal use of AI and corporate stack automation. This includes secure LLM integrations, prompt APIs, CI/CD tooling, infrastructure-as-code, and systems that bridge the needs of IT, Security, and R&D. Our goal is to make internal operations smarter, faster, and more reliable through modern engineering practices and emerging technology.

About the role (you)

As the Director of AI & Dev Ops Engineering, you’ll lead a team of engineers focused on building and operating core internal platforms that support intelligent systems and developer velocity. You’ll define strategy, prioritize roadmap, and partner closely with teams across Klaviyo to operationalize AI tooling and modernize infrastructure.

This role owns both the deployment and management of AI tools (e.g. ChatGPT, Claude, Gemini, Glean) and the development of internal Dev Ops systems (CI/CD, automation, monitoring, infrastructure provisioning). You’ll deliver shared services that empower internal teams to work more efficiently and focus on solving high-value problems.

How you’ll have an impact

• Lead the engineering roadmap for internal AI platform services, Dev Ops automation, and infrastructure tooling.

• Build and scale developer tools such as CI/CD pipelines, container orchestration, Git Hub integrations, and infrastructure-as-code.

• Partner with Engineering, Security, and Data teams to integrate LLMs and AI services in a safe, scalable way.

• Stand up and support AI services: vector search, internal plugins, prompt orchestration layers, and secure API routing.

• Enable teams across Klaviyo to integrate AI into workflows by supporting pilots, building SDKs, and maintaining internal knowledge bases.

• Drive systems automation for IT services—e.g., identity provisioning, SaaS lifecycle management, endpoint posture, and reporting.

• Mentor and grow a high-performing team of engineers with a focus on technical depth, quality delivery, and service ownership.

• Represent Global IT in technical steering conversations with R&D, Product Infrastructure, and Sec Ops.

• Transform workflows by putting AI at the center, building smarter systems and ways of working from the ground up.

What we’re looking for

• 10+ years of experience in infrastructure, Dev Ops, platform engineering, or enterprise IT systems.

• At least 3+ years leading technical teams in high-growth or scaled organizations.

• Proven experience designing and operating CI/CD systems, infrastructure-as-code (Terraform or similar), and observability stacks.

• Familiarity with integrating AI services or LLM APIs into business systems (e.g., OpenAI, Anthropic, Google Gemini, Glean).

• Strong understanding of platform scalability, service reliability, and engineering lifecycle automation.

• Experience managing cloud infrastructure (AWS, GCP), container orchestration (Kubernetes, ECS), and developer platforms.

• Ability to drive…
