Stellenbeschreibung

thellma Legal AI Startup

We are an early stage AI Legal Startup trying to make product compliance easier. Right now, regulatory compliance is messy, complicated and barely understood by anyone. We are building the backbone of automated legal advice for product compliance. And we are growing! We just got the EXIST grant, and have a stipend for a 3rd person, who wants to grow with us! Until now, its just been the two of us: a US engineer and a German lawyer, who have known each other for like a decade.

We are looking for a 3rd team member to focus on building the product in Legal AI.

Tasks

At Thellma, you will create hypotheses, build small experiments, learn and ship features. You will own the product pipeline, from gathering user feedback to managing our backlog.

Youll work alongside the founders in our office in Berlin Charlottenburg, in the midst of a community of ambitious AI start-ups.

Be the Quality Gatekeeper: Using honest testing, monitoring, evals, and manual checks: Ensure what we ship works, produces honest & accurate results, and will impress our customers.

Requirements
