AI Product Engineer

Speak is revolutionizing language learning through AI technology, having recently achieved a $1B valuation with their Series C round. As an AI Product Engineer, you'll be at the forefront of developing innovative language learning solutions powered by Large Language Models (LLMs).

The role combines full-stack engineering with AI/ML expertise, focusing on creating and enhancing LLM-powered features that serve millions of users across 40+ countries. You'll be working on conversational onboarding, lesson experiences, grammatical assessment, and personalized learning systems.

The company has strong backing from prestigious investors including Accel, OpenAI, Founders Fund, Y Combinator, and Khosla Ventures. With a team of 90+ spread across global offices in San Francisco, Seoul, Tokyo, Taipei, and Ljubljana, you'll be part of an international environment making a real impact on how people learn languages.
