Founding Product Engineer - Listen Labs

Remote, USA Full-time Posted 2026-06-21

Listen Labs Everyone hates surveys. They’re tedious to fill out and give shallow data. That’s because they’re only a proxy for the real thing: conversations. Through a conversation, you can ask follow-up questions and get deep insights in a way that’s fun for the interviewee. Except you can’t have 1:1 conversations with everyone… Listen Labs has built an AI interviewer that can ask follow-up questions, like a conversation, but at the scale and ease of use of a survey. Technical Challenges Turn qualitative data into quantitative insights Listen Labs clusters free-form conversation into a structured format. This is not a trivial task. We use embeddings, fine-tuned large language models, and more to solve these problems. Ask the right questions Having a great conversation is not trivial. We’re fine-tuning and prompting in novel ways to get the right output from LLMs. Multi-modality We’ve built the fastest speech-to-speech pipeline but there’s a number of challenges we need to address to make it better. Our interviewer has audio input and output to the LLM and that’s tricky to get right. Investors There’s been $30B+ of market cap created from bringing surveys online. Our partner at Sequoia, Bryan Schreier, was the first investor in Qualtrics – the $12B survey company.
