We are looking for a Fullstack Engineer and AI enthusiast to join our engineering team. CASUS simplifies legal compliance with AI-powered tools. Our mission is to make complex workflows intuitive and efficient for law firms and legal teams.
We are rebuilding the core tool stack of the legal industry from the ground up.
Lawyers still work in workflows designed decades ago: fragmented tools, manual reviews, static templates, and compliance processes that don’t scale. We think that’s unacceptable in an AI-first world.
