Senior Growth Marketing Manager - Korea

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.

💬 동료의 코멘트

스픽의 브랜드 마케터 두현입니다. 저는 브랜드 마케팅을 하고 있지만, 바로 옆에서 퍼포먼스 마케팅을 지켜보며 많은 걸 느끼고 배웁니다. 스픽의 퍼포먼스 마케터는 단순히 숫자만 보지 않아요. 숫자로 표현될 수 없는 사람들의 정성적인 반응, 브랜드에 대한 애정도, 행동 패턴, 관심사까지 두루 살펴보며 최적의 UA 채널을 찾아냅니다. 크리에이티브에 있어서도 브랜드 매니저나 디자이너 만큼, 어쩌면 그보다 더 탁월한 감각을 갖고 있으며 타겟과 브랜드에 대한 높은 이해를 토대로 효율성 높은 마케팅을 전개합니다. 누구보다 제품에 대한 애정과 자부심을 갖고 있고요. 좋은 제품과 좋은 문화가 갖춰진 환경에서 이를 널리 알리고 싶은 마음이 있는 마케터라면, 지원을 고민하지 마세요.

Why work at Speak

1. Join a fantastic, tight-knit team at the right time: we're growing very quickly, we've most recently raised our Series C from some of the top investors in the valley, and we've achieved product-market fit in our initial markets. You'd join at a magical time when a single person could significantly change the course of the company.

2. 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.

3. 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, and Tokyo, 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. We’re helping millions of people achieve their goals and improve their lives.
