Senior Full-stack Engineer

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.

Speak first launched in South Korea in 2019, where it has become the number one language learning app, and now serves learners across many markets and 15+ languages. With over $150m raised in venture investment from OpenAI, Accel, Founders Fund, Khosla Ventures, and more, Speak has established itself as one of the world's leading AI companies.

As a Senior Full-stack Engineer, you'll be working on building novel AI-powered product experiences, focusing on backend development while maintaining full-stack capabilities. You'll collaborate closely with product, design, and machine learning teams to develop programmatic, conversationally-driven language learning features. Your role will be instrumental in shaping the future of the company.
