Frontend Engineer

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 role

We’re hiring a

Frontend Engineer

to set the standard for how professionals experience AI. This role goes beyond translating designs. You’ll be the one

creating flows, shaping interaction models, and coding them into reality

. From requirements and early ideas, you’ll design and engineer systems that are intuitive, responsive, and visually stunning.

You’ll work directly with the CPO and a team of talented engineers to

define our design language, build our design system, and bring motion and refinement into every corner of the product

. The work you do will shape not only how the product

feels

it will define the form factor of AI in legal tech.

What You’ll Be Working On

Translate complex AI-driven workflows into simple, elegant, and intuitive interfaces.

Prototype and iterate on new interaction models, from micro-interactions to end-to-end flows.

Build and evolve our design system, ensuring both visual consistency and engineering reliability.

Deliver highly-performant, reliable UI components with Vue.js and TailwindCSS.

Use motion, transitions, and micro-interactions to bring interfaces to life.

Balance speed of iteration with high-quality standards in code, design, and usability.

What We’re Looking For

A rare hybrid: an engineer with a designer’s eye. You can both design and code at a high level.

Strong skills in Vue.js, TypeScript, and TailwindCSS, with a portfolio of coded work.

Proven experience designing and building flows, systems, and interaction patterns, not just individual screens.

Obsession with motion, detail, and the overall feel of products.

Comfortable working from rough requirements and shaping them into elegant, usable systems.

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.

Why join us

Be part of a product-driven team reinventing how legal professionals work.

Join early and shape the foundation of a fast-growing, high-impact startup.

Work in a place where hierarchy doesn’t matter — only the best ideas do.

Collaborate with a top-tier team of engineers, researchers, and entrepreneurs.

Competitive compensation, employee benefits and strong upside as we grow.

An inspiring place to work in the heart of Rotterdam.

Shape the future of legal work with us.
