Connect directly with founders of the best YC-funded startups.
As part of Liva’s engineering team, you’ll have end-to-end ownership over projects that define how frontier AI data is collected, validated, and quality-assured. You’ll work on a mix of platform engineering and infrastructure development (scaling data platforms, building human-in-the-loop systems, designing evaluation pipelines).
You might build a mobile app for data collection one week, design an automated QA pipeline with intelligent validation systems the next, and then improve our annotation platforms. You’ll also play a key role in developing AI agent–driven workflows that automate core operations.

Liva’s mission is to make AI look and sound truly human. The AI voices and faces today feel off, and lack the capability to reflect diverse people across different ethnicities, races, accents, and career professions. We’re fixing that by building the world’s richest library of human voice and video data, fueling the next generation of realistic AI.
