Senior Full Stack Developer (m/w/d)

Introduction

Legartis is on a mission: to unlock legal work at scale.

We have already set the standard for AI-powered contract review, helping teams work with greater precision than ever before. But that is just the beginning. We are building a holistic platform that goes far beyond review - connecting people, ideas, and knowledge to fundamentally change how legal teams operate.

When you join Legartis, you don’t just take a job - you take ownership. We are a team of product builders and legal experts who believe that true problem-solving requires more than just code; it requires a thoughtful process. We don't chase hype; we build substance. Each of us is ambitious to grow personally and professionally. If you are excited by the prospect of working with exceptional people and building an AI powered SaaS product which shapes the future of law - then this is the moment and the place.

• Able to build a full feature from frontend to backend

We offer

• Zero Micro-management: We hire experts and stay out of their way. You define the tech and drive the features you build.

• Hard Problems, No Fluff: Legal tech is technically complex and underserved. You’ll solve real-world logic and data challenges alongside a team that actually knows their stuff.

• Skin in the Game: Through our ESOP, you’re not just an employee; you’re an owner. When the company hits a milestone, you benefit directly.
• Work-Life Reality: We’re based in the center of Leipzig because we like it here. We actually hang out—whether it’s testing new restaurants, hiking, or just grabbing a beer.
