Senior iOS Engineer

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.

ABOUT THIS ROLE

This is an extraordinary moment to join us. We're in the middle of a fundamental agentic shift in software development, and are embracing the change We're operating in an agentic-first world, where the role of a builder is shifting from writing every line of code to designing systems that build, test, and improve themselves.

At Speak, you'll use AI agents as core collaborators in your day-to-day workflow—helping you move faster, explore more ideas, and focus on the highest-impact problems. That means embracing ambiguity, iterating quickly, and working fluidly across functions—not just within a single discipline.

We're looking for an iOS engineer who is excited to rethink how work gets done in an AI-native environment, and who want to help define what building looks like in this new paradigm.
