Speak - Full-Stack Engineer

• $150K – $280K • Offers Equity • At Speak, our compensation philosophy is based on work experience, interview performance, leveling and other factors evaluated during the hiring process. • 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. • We’re looking for a senior full-stack engineer to serve as a hands-on technical contributor for Speak for Business, the pod building the enterprise layer of Speak. You’ll work across the B2B product surface — partner portals, reporting, B2B subscription mechanics, admin experiences, and learner features that require an enterprise touch. You’ll work primarily in TypeScript across Node.js and Postgres, partnering with engineers in adjacent pods where experiences cross team boundaries. • You’ll turn product requirements and business goals into clear technical designs, contribute hands-on across the stack, and help set a high bar for architecture, reliability, and code quality on a small, fast-moving team. Near-term work includes B2B onboarding flows, partner-facing reporting, subscription and billing mechanics, and enterprise-ready features that support our growing Sales and CS motion. • Do your life's work with people you’ll love working with: we care strongly about our craft and want every person at Speak to feel like they're growing every day. We believe in the idea that working with people you both enjoy and have respect for makes everything better. We hire thoughtfully and only work with people we admire deeply. • Do your life's work with people you’ll love working with: • Global in nature: We're live in over 40 countries and launching in a number of new markets soon. We have dedicated offices in San Francisco, Ljubljana, Seoul, Tokyo, and Taipei, and you’ll have the opportunity to talk to users in each of these regions on a regular basis as well as travel. • Global in nature: • Impact people's lives in a major way: Learning a language is one of the single most life-changing skills one can learn, and right now 99% of people never achieve their goal because the process is broken. We’re helping millions of people achieve their goals and improve their lives. • Impact people's lives in a major way: • Speak does not discriminate based upon race, religion, color, national origin, gender (including pregnancy, childbirth, or related medical conditions), sexual orientation, gender identity, gender expression, age, status as a protected veteran, status as an individual with a disability, or other applicable legally protected characteristics.
