Own and manage the Klaviyo Language hub (language governance) and associated processes across all languages.
• TMS and MT ownership
  :
  Own and manage our TMS (Smartling) as it relates to Product, Help Centre and Customer Education, ensuring optimisation for different content types, CMSs, language assets and resources, and integrating and managing machine translation within our workflows for all supported languages.
• AI‑first translation platform

  Partner with Engineering, Product, Data and other internal teams to help design and build an AI‑first translation platform that leverages MT, generative AI and automation to increase localisation speed, consistency and scalability while maintaining quality.
• Transform workflows by putting AI at the centre, building smarter systems and ways of working from the ground up.

  Collaborate with the broader Localisation team to deliver a high‑quality localised experience for international customers, drive scale in localisation, and resolve issues and blockers quickly.
