We’re building a world-class team to redefine knowledge work with AI
Zeno is a legal AI startup building a platform that helps lawyers research, review, and draft documents with real legal reasoning — not just text prediction. We’re developing technology that can:
- Search and retrieve statutes, case law, and commentary with high precision.
- Reason step-by-step, applying legal tests and weighing precedents.
- Explain every answer transparently, so lawyers can trace conclusions back to the exact sources.
Where most tools automate surface-level tasks, we’re focused on replicating the way lawyers actually think through legal problems, making depth and trust the foundation of everything we build.
You’re joining an early-stage startup that is already working with leading firms. Backed with €3M in seed funding, we’re now scaling a team of engineers and thinkers who want to solve real problems, drive innovation, and create lasting change in the legal sector.
The roleAs a Software Engineer at Zeno, you’ll play a critical role in designing, building, and optimizing AI-powered applications that redefine how legal professionals work. You’ll work across the entire tech stack, solving complex technical challenges while ensuring a seamless user experience.
This is an opportunity to build AI-driven applications from the ground up, work with Litestar (Python) and Vue.js, and contribute to a high-impact product that’s transforming the legal industry.
What you’ll be working on- Identify high-impact challenges and build practical, scalable solutions.
- Work on efficient, secure, and high-performance backend services.
- Build modern, responsive UI components.
- Ensure high-quality code while optimizing for rapid iteration and impact.
- You’re experienced in both backend and frontend development, with a passion for building impactful applications.
- Strong experience with back-end frameworks such as Litestar or FastAPI and front-end frameworks such as Vue.js or React.
- You take ownership, thrive in an agile environment, and are eager to experiment with new solutions.
- Knowledge of DevOps, cloud platforms, and deployment pipelines would be beneficial.
Things will break, priorities will shift, and there won’t always be a playbook. You’ll wear multiple hats, ship fast, and learn faster. Some weeks will feel chaotic, some problems will feel bigger than your role. That’s the nature of the ride from startup to scale-up: if you need stability and structure, this won’t fit. But if you thrive on ownership, speed, and building from zero, you’ll love it here.
