Our SaaS platform provides businesses of all sizes with powerful, easy-to-use marketing automation tools, making first-party data accessible and actionable like never before. We are a team of ambitious, bold peers who are insatiably curious and meticulous in our craft. As we scale globally, we are seeking a foundational leader to build and lead our Site Reliability functions from our new strategic hub in Dublin.

About the Team

The SRE team is the bedrock of trust for the 200,000+ businesses that rely on Klaviyo to power their growth. This team is responsible for the secure reliability, scalability, and performance of our entire platform: from our core data processing pipelines to our cutting-edge AI services. As a foundational leader in our new Dublin office, you will build this team from the ground up, establishing a center of excellence for platform integrity and playing a pivotal role in Klaviyo’s European expansion. You will be the ultimate custodian of the trust our customers place in us every day.

How You'll Make a Difference

Architect and Lead: Define the vision, strategy, and roadmap for a unified SRE organization. You will build and mentor a world-class, multi-disciplinary team of engineers in Dublin, fostering a culture of operational excellence, proactive problem-solving, and blameless learning.

Champion Secure Reliability: Drive a "secure and reliable by design" philosophy across all of engineering. Partner with product and platform teams to embed reliability principles into the entire software development lifecycle, from initial design to production deployment.

Own Platform Integrity: Take ownership of the availability, latency, performance, efficiency, change management, monitoring, emergency response, and capacity planning for Klaviyo’s global platform.

Drive Automation: Build the "paved road" for Klaviyo engineers by developing automated, self-service tooling and infrastructure that enables teams to "move fast, no shortcuts".

Ensure Global Compliance: Serve as the on-the-ground technical leader for GDPR and other international data protection regulations. You will be responsible for implementing and verifying the technical controls that safeguard customer data and ensure compliance.

Lead Through Incidents: Command reliability incidents, guiding teams to rapid resolution while fostering a culture of blameless post-mortems that drive meaningful, systemic improvements.
