Careers at ZAAN

Build the AI lawyers trust.

ZAAN reads contracts the way a meticulous senior associate would: clause by clause, against the firm's own playbook, citing every source. We are a small team of engineers, researchers and lawyers, and we hire people who care about precision as much as we do.

Why ZAAN

What we hold to.

A handful of principles, closely held. They shape the product, the hiring bar, and how we spend our time.

01

Precision before polish

A legal tool that is almost right is wrong. We ship slowly and check our work. Shortcuts the user cannot see are still shortcuts.

02

Simplicity without loss

Every interface decision removes something. We remove weight, never depth. Restraint is a feature.

03

Legal access for all

Rigorous legal work should reach the many, not entrench the few. It is why many of us are here.

04

Write, then write again

Clear writing is clear thinking. A memo that reads cleanly almost always has a cleaner architecture underneath.

05

Quiet ambition

We do not announce what we have not finished. The work speaks; we try not to.

06

A small, permanent team

We hire slowly, for people who want to stay. Growth happens inside roles as often as between them.

How we hire

Three steps to joining the team.

We aim to decide within three weeks of your first reply. You will speak to the team you would join before we make an offer.

Write to us and we will keep your details in mind when something opens up that fits. No drip campaigns, no recruiter noise.
