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:
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 role As a Product Engineer at Zeno, you’ll build product experiences that users rely on for serious, high-stakes work.
This is not a “take tickets and implement UI” job. You’ll work end-to-end: from shaping what the product should do, to building it, to measuring whether it actually works in the real world. You’ll sit at the intersection of product thinking and engineering execution, turning complex capabilities into simple, fast, dependable workflows.
If you enjoy shipping quickly and care about correctness, clarity, and craft, you’ll have a lot of room here
What You’ll Be Working On
Take responsibility for a user problem area and drive it from idea to shipped experience to iteration.
Implement workflows across frontend and backend, including data modeling, API design, UI state, and performance.
Integrate underlying services and models into features that feel predictable, explainable, and safe to use.
Build experiences that hold up when inputs change, information updates, or work needs to be revisited later.
Push for maintainable patterns, good abstractions, strong defaults, and fewer “one-off” solutions.
Use small increments, feature flags where needed, and tight feedback loops—without letting quality degrade.
What We’re Looking For
You’ve shipped real product features end-to-end and understand the tradeoffs across frontend, backend, and data.
You naturally think about user experience, adoption, edge cases, and what “good” looks like—before writing code.
You’ve worked in products with real state, permissions, workflows, or domain constraints (not just CRUD apps).
You can make good calls under ambiguity, communicate tradeoffs clearly, and keep momentum without creating mess.
You care about performance, reliability, testing, and clean interfaces. You leave systems better than you found them.
You work well with designers and PMs, and you can translate fuzzy problems into concrete solutions.
Who You Are
The ride from startup to scale-up 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.
