Content Localization Specialist (Japanese / Korean)

ABOUT US Our mission is to reinvent the way people learn, starting with language. Learning a language can change a life by opening doors to new cultures, careers, and communities. Two billion people around the world are actively trying to learn a language, but the best way to learn (one-on-one tutoring) is hard to access at scale and hasn’t been meaningfully improved in decades. Speak is building a human-level, AI-powered tutor in your pocket: a conversation-first experience that lets learners actually speak, get instant feedback, and progress through carefully designed lessons. The result is a complete path from beginner to confident speaker across multiple languages. Speak first launched in South Korea in 2019, where Speak has now become the number one language learning app, and we now serve learners across many markets and 15+ languages. Speak is one of the world’s leading AI companies, with over $150m raised in venture investment from OpenAI, Accel, Founders Fund, Khosla Ventures, and more, with a distributed team across San Francisco, Seoul, Tokyo, Taipei, and Ljubljana. ABOUT THIS ROLE We are looking for a talented multilingual superstar (Japanese/Korean/English) with skills and backgrounds in translation and localization. The primary contribution is to localize our in-app content for the Japanese market. The secondary contribution is to create high-quality Korean content for the Japanese market with training and support. We want an expert with excellent oral and written communication skills in both languages. This candidate should have a sharp linguistic understanding of both Korean and Japanese, with working professional proficiency in English. WHAT YOU’LL BE DOING - Content translation and localization - Perform Japanese -Korean translation and localization for in-app learning and marketing content from a pedagogical perspective.

• Iterate and polish the translated/localized content based on QA tasks in pursuit of an optimal learning experience to Koreans learners teaching Chinese - Content development and writing - If needed, design and write in-app learning materials (e.g., lesson scripts, activities, vocabulary lists) in a systematic way for Korean learners at different levels of Simplified Chinese proficiency under training and guidance of the manager.
• Content project support - If needed, support operation of content-related projects, such as uploading scripts, QAing lessons, coordinate pieces of the operation under training and guidance of the manager.
• Communication and collaboration with international team members - Receive directions well form the manager, implement instructions, complete projects, and maintain clear communication from end-to-end.

• Do your life's work with people you’ll love working with: we care strongly about our craft and want every person at Speak to feel like they're growing every day. We believe in the idea that working with people you both enjoy and have respect for makes everything better. We hire thoughtfully and only work with people we admire deeply.
• Global in nature: We're live in over 40 countries and launching in a number of new markets soon. We have dedicated offices in San Francisco, Ljubljana, Seoul, Tokyo, and Taipei, and you’ll have the opportunity to talk to users in each of these regions on a regular basis as well as travel. 4. Impact people's lives in a major way: Learning a language is one of the single most life-changing skills one can learn, and right now 99% of people never achieve their goal because the process is broken.

• Highlight your Excel expertise by attaching a one‑page “Localization KPI Dashboard” you built (e.g., tracking translation turnaround, quality scores, and cost per language). In the cover letter reference the exact formulas or pivot‑tables you used, showing you can turn raw data into actionable insights for Speak’s AI‑driven lessons.
• Create a short, bilingual sample of localized lesson content (≈200 words) that demonstrates both Japanese and Korean cultural adaptation. Include a brief commentary on why you chose specific terminology or phrasing to align with Speak’s conversational‑first tone, and link the file in your resume’s “Portfolio” section.
• During the interview, be ready to discuss how you would audit existing Korean/Japanese lesson scripts for consistency with Speak’s AI feedback engine. Prepare a 5‑minute case study: pick a sample lesson, identify three localization issues, and propose concrete fixes that improve AI‑generated pronunciation hints.
• Emphasize remote‑work discipline: list the collaboration tools you use (e.g., Notion for task tracking, Slack for quick clarifications, and Google Sheets/Excel Online for real‑time data sharing). Mention a specific routine—like a daily 15‑minute “language‑quality stand‑up”—that ensures timely delivery across time zones.
• When negotiating salary, research South Korean market rates for bilingual content specialists (≈₩45‑55 M KRW base plus performance bonuses). Quote your proven metrics (e.g., 20 % reduction in turnaround time or 15 % increase in learner satisfaction) to justify a higher band, and ask if Speak offers equity or profit‑sharing tied to the AI tutor’s user growth.
