US marketing technology firm Klaviyo is investing in its Dublin engineering hub at Dame Street, Temple Bar, its first engineering location outside the United States, with plans to grow headcount by up to 50% in 2026, building on more than 100 roles created in the past year.

Tech Buzz Ireland reported that the Dublin team will take direct ownership of core systems powering Klaviyo's AI strategy, including messaging infrastructure, data analytics, and personalisation capabilities across marketing, service, and analytics functions work described by the company as having global impact across its platform serving 193,000 consumer brands worldwide.

Open engineering roles span senior software engineering, engineering management, infrastructure security, and internal platform development, with further positions expected as the team scales throughout 2026.

Surabhi Gupta, chief technology officer at Klaviyo, said: "Dublin will own core parts of how Klaviyo's platform works, not support them from the sidelines. We're looking for engineers who want to solve genuinely hard problems, building reliable, high-performance systems at scale. The people joining us here will ship features that reach millions and push what's possible with AI and data."

Ben Jackson, managing director and VP for EMEA at Klaviyo, said the company is growing and scaling fast across Europe with significant opportunities ahead as it builds out its AI products, adding that working in Dublin means engineers work with billions of data points daily at the scale of a large platform with the pace and ambition of a company that has significant runway ahead.

Michael Lohan, chief executive of IDA Ireland, said Klaviyo's decision to build its engineering capability in Dublin is a strong endorsement of the quality of Ireland's technology talent and its innovation ecosystem.
