AI Product Engineer

As an AI Product Engineer at Speak, you'll play a pivotal role in developing the future of language learning and creating the most effective path to language fluency. Your primary responsibility will be developing innovative product experiences powered by Language Learning Models (LLMs) and deploying them to millions of users.

Your tasks will span the full stack and beyond, from evaluating models and testing prompts to developing and iterating on various product features such as our conversational onboarding and lesson experiences, grammatical assessment and feedback, and personalized lessons.

We're constantly pushing the boundaries of what LLMs can do to provide an exceptional and unparalleled language learning experience to users in over 30 countries worldwide.

What you'll be doing:

• Developing and deploying LLM-powered language learning products across the full stack, as well as enhancing the quality and performance of existing AI-powered features within Speak
• Collaborating cross-functionally with other Engineering teams, Applied ML, Product, Design, and Content
• Refining our process for building LLM apps, including best practices for prompting, experimentation/evaluation, LLM Ops, measuring quality and performance, etc.
• Scaling existing product features to many more users and languages

What we're looking for:

• 3-5+ years of experience in full stack/backend, product-focused software engineering
• Strong product intuition — the ability to think broadly and cross-functionally about innovative LLM-powered capabilities and product experiences
• Ability to work independently and build at a high velocity
• Interest in building with LLMs

Bonus:

• You have real-world experience developing and deploying LLM apps and a strong understanding, gained through experience, of what works and what doesn't
• A keen intuition for improving performance and output quality of LLM systems
• Experience with LLM Ops and tools (e.g., vector databases, RAG, prompt ops)
