Requirements
  • 7+ years of localisation or internationalisation experience, ideally within a consumer-facing app, media company, or content-heavy digital product
  • Deep experience localising video content at scale
  • Strong leadership skills with experience guiding small teams and collaborating across disciplines (product, design, video, growth)
  • Familiarity with localisation platforms and workflows (e.g., Lokalise, Phrase, Smartling) and video localisation tools or partners
  • A user-centric mindset with a sharp editorial eye — you understand the importance of nuance, tone, and cultural sensitivity
  • Data-literate: comfortable setting KPIs, interpreting metrics, and using insights to improve content effectiveness
  • Excellent communication and project management skills: highly organised, clear, and collaborative
  • Fluency in English required; fluency in one or more additional languages is a strong plus
Responsibilities
  • Own and lead the localisation strategy and execution across the full content spectrum — including product UI, marketing, and video-based content (e.g., workout videos, audio meditations/walks)
  • Build and refine scalable localisation workflows — including tools, QA processes, content prep, and post-production performance
  • Guide localisation for video content, including subtitling, dubbing/voiceover, cultural adaptation of scripts, and in-video graphics/text using AI
  • Collaborate closely with producers, editors, and motion designers to ensure localisation is considered early in video planning and production
  • Manage a small but growing team of localisers, freelancers, or vendors — mentoring them, reviewing work, and ensuring alignment on tone, brand, and execution
  • Select and manage localisation platforms and oversee vendor relationships across translation, voiceover, and post-production
  • Develop and maintain core assets such as tone of voice guides, glossaries, style guides, and localisation toolkits
  • Use data to measure localisation quality and performance — demonstrating impact on user engagement, retention, and satisfaction across markets
  • Act as an internal advocate for localisation — educating teams on best practices and encouraging early integration in product and content workflows
