# AI Research Engineer

Company Overview: Everyone builds up knowledge and experience that could help someone else, but very little of it ever leaves their head. When they’re busy, asleep or just not in the room, the people who need it are left waiting. TwinCafe, by Viven, gives everyone a digital twin to close that gap. A twin carries a person’s expertise and way of speaking, so it can talk with others for them, even about questions they’ve never been asked before. It draws only on what its owner has taught it, and when a question falls outside that, it hands the conversation back to them. Educators, lawyers, coaches, recruiters, job seekers and creators use twins to stay reachable for students, clients and audiences, on the web, on mobile and on their own sites. Owners decide what their twin knows and can change it whenever they like. Most AI products help people get more done. We’re building one that helps people share who they are. Role Overview We're seeking an AI Research Engineer to tackle TwinCafe's hardest technical problems, from the first idea to shipped product. This is a 0-to-1 role: you'll proactively identify opportunities to improve AI quality, define how to measure success, experiment wit
