Developer Software Development

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.
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.

We’re hiring a Software Engineer. As a Software Engineer at Zeno you'll be a hands-on engineer owning the foundations that make the product scalable and self-serve.
You’ll build the core systems that every feature depends on: onboarding and activation, account/workspace structure, permissions, usage limits, and the mechanics behind international rollout. You’ll deliver a strong foundation, then continue as a senior IC within the team that best matches your strengths.

Build onboarding and activation flows Ship clear, reliable paths that get new users to value quickly, with strong defaults and minimal friction.
Implement account and workspace foundations Build and evolve the structures for organizations, workspaces, matters, and users so the product has a stable base.
Harden and simplify core patterns Replace ad-hoc solutions with clean interfaces and reusable components that make future development faster.

Strong full-stack engineering experience You’ve shipped production features across frontend, backend, and data models.
Experience with foundational product systems You’ve worked on areas like onboarding, permissions, metering, billing/usage logic, or account structures.
High ownership as an IC You can take a loosely defined area, drive it forward independently, and ship iteratively.
Comfort with ambiguity You can define milestones, make tradeoffs, and improve based on real usage data.
Strong collaboration You work well with product and engineering partners, communicate tradeoffs clearly, and keep momentum.

You prefer shipping real improvements over writing specs or running process.
You take pride in leaving the codebase and product more coherent than you found it.
You want to own a critical area and build it properly.

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. 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.

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