To reinvent the way people learn, starting with language.
Role
Who you are
- 5+ years of experience building high-quality, production-scale web applications, with strong proficiency in React and Node.js
- Ability to balance building the "right way" with shipping quickly when needed
- Enjoyment in iterating rapidly and delivering value through frequent releases
- Excellent communicator who enjoys collaborating across functions

- Deep experience with Next.js
- Strong knowledge of Postgres and data modeling best practices
- Familiarity with identity and access domains (authentication, authorization, auditing)
- Experience with subscription or billing systems

What the job involves
- We’re looking for a Full-stack Technical Lead to drive the next evolution of our growth and marketing experiences
- You’ll work across a modern web stack—Next.js, Node.js, and Postgres—to build, optimize, and scale interactive product features that help us acquire and engage users in creative new ways
- As a key member of the Growth Marketing team, you’ll own high-impact initiatives such as user registration, subscription management, and viral campaign experiences
- You’ll also guide improvements to our technical architecture and help establish best practices as we modernize a recently migrated Next.js codebase
- Leading growth-focused projects that drive user excitement and large-scale engagement (e.g. Your Year in Conversation, interactive influencer partnerships)
- Designing and building AI-driven web experiences (e.g. speaking practice with AI Tutor)
- Collaborating closely with cross-functional partners across product, design, and marketing to deliver high-impact initiatives
- Enhancing the architecture, reliability, and development patterns of our full-stack web application through incremental improvements
Our take
Language is one of the most powerful skills a person can learn. It helps us connect with people, understand different cultures, travel with confidence, and unlock new opportunities in life and work. But learning a language is often easier said than done. Traditional lessons are daunting and slow, not to mention expensive, and many people never get enough practice actually speaking out loud.
Speak is changing that by putting an AI language tutor right in your pocket. Instead of focusing on memorising endless vocabulary lists, Speak is built around real conversations. Learnings speak from the very beginning, receive instant feedback, and work through lessons designed to help them improve naturally over time. It brings the experience of practicing with a personal tutor to millions of people, making language learning more accessible.
That approach is clearly working too. Since launching in South Korea in 2019, Speak has now grown into the country's number one language learning app and now supports learners across more than 15 languages worldwide. Backed by leading investors, including OpenAI, Speak has become on of the world's leading AI language learning companies. And as AI becomes better at understanding and responding like a real conversation partner, Speak is in a good position to help even more people not just learn a language but become confident in it.
