The company
Temis is an AI-native law firm. Not a legaltech vendor selling software to law firms, an vigente firm, regulated and delivering work to real clients, where AI does the first 80% of every matter and senior lawyers validate the final 20%.
We run the firm on our own infrastructure: legal agents built for specific workflows, credits based pricing instead of billable hours and an environment built for GDPR compliance from day one.

The role
You will be the legal founder of a firm that has no precedent in Spain. Concretely, that means you own three things:
1. Legal quality and liability. You are the final signature. You design the validation layer (what an AI output must satisfy before it reaches a client, who reviews what, where the human sign-off sits, and how we prove it. If a deliverable is wrong, that is your system).
2. Turning legal work into product.



Every matter we take on is a candidate to become a repeatable agent. You decompose legal workflows into steps a machine can run, specify what each agent must check, write and iterate the prompts and rule sets, and read the outputs critically enough to know when the model is confidently wrong. This is the core of the job, and it is where most excellent lawyers fail.
3. Building the legal team. Hiring, training and managing the lawyers who work this way (which is a different profile and a different day-to-day than any firm they've come from).
You will also be a founder: pricing, client conversations, regulatory positioning, investor rooms and the arguments about what we are and aren't willing to do.

What we need
- Qualified to practise in Spain. Colegiado, active. This is non-negotiable, the firm's legal capacity depends on it.
- Senior. Roughly 8+ years, with real ownership of matters and clients. Ideally corporate/commercial (M&A;, VC, contra
