About the role

About us

Our mission is to reinvent the way people learn, starting with language. We begin by teaching the next billion people English, Spanish, and French.

English is the global language of business, culture, and communication, and over 1.5 billion people around the world are actively trying to learn right now. Others dream of communicating with the half-billion native Spanish speakers across the globe. The problem is that it's nearly impossible to learn to speak a language without constant access to a speaking partner. Grammar and vocab apps don't really help – you need to actually converse with someone.

Speak is on a journey to fix this. We're creating an AI-powered experience that replicates the flow of a conversation, without needing a human on the other end. The goal is to make it radically more accessible to be able to have conversations in a foreign language and eventually help hundreds of millions of people gain fluency who otherwise wouldn't be able to.

We started on this journey over five years ago and we've still got a long ways to go. We're thoughtfully adding new team members only when we think they can truly play a big role in our mission.

Speak launched first in South Korea where we have quickly grown to become the top grossing education app in the country. We have now delivered this winning product to more than 30 countries globally and are continuing to expand to more markets in the coming months. The company is well funded, raising a recent Series B backed by investors like OpenAI, Founders Fund, Y Combinator, Khosla Ventures, Lachy Groom, Josh Buckley, and others. We’re a team of 75 based primarily in SF, Seoul, Tokyo, and Ljubljana.

About this role

We are looking for a full-time Korean English as a Second Language (ESL) and English as a Foreign Language (EFL) content writer to join Speak’s content team in creating high-quality language learning in-app content for the Korean market.

We are looking for a superstar writer and curriculum developer who understands Korean English learners' thought processes when approaching English learning. We seek someone who has a full understanding of Korean and English as languages AND has a history of successfully teaching or creating learning modules/materials for English learners in Korea.

In addition to script-writing, teaching, and curriculum expertise, we also want this role to have a strong product sense and understanding of how best teaching and technology can be integrated through content.

What you’ll be doing

  • Curriculum design and writing - Design curriculum and write learning materials (e.g., lesson scripts, activities, vocabulary lists) in a systematic way for English learners (and especially Korean English learners) at different levels of English proficiency.

  • Manage or facilitate content projects - Either having end-to-end ownership or participating in content projects from content planning to writing, to production all the way to launch.

  • Translation and localization - Perform English-Korean translation and localization for in-app learning and marketing content.

  • Content development and prototyping - Participate in developing innovative learning content powered by advanced AI (artificial intelligence) and ML (machine learning) technology.

  • Content strategies and decision-making - Participate in content team meetings, discussions, and decision-making; As a member of the Korean content team, facilitate the development of content strategies that suit Korea’s market needs and are aligned with the company's vision and goals.

  • Communication and collaboration with international team members - This can take place face-to-face, remotely, asynchronously, or through business travel, whichever makes sense.

  • Data Analysis - Analyze user data, conduct user interviews, and collect feedback to make informed content development decisions. Evaluation of content performance metrics to adjust and enhance learning materials for improved user engagement and learning efficiency.

  • Team Management - Hire and manage freelance or contract content writers, ensuring their work aligns with company standards and instructional design practices. Ensure a robust workflow, distribute tasks, provide guidance, and review the work of these writers to ensure high-standard outputs.

  • Passion for technology-assisted language learning and willingness to learn and use advanced technologies for all aspects of work (Notion, internal tools, prompt engineering, etc.)

  • A fast learner, team player, skilled communicator, and creative problem-solver


  • Translation/localization experience
