No. Most residents had never built software. You work with AI tools that write the code, and a mentor who builds shows you how to direct them.

Is legal engineering a job?

Yes. Law firms, in-house teams and legal AI companies hire legal engineers. Many lawyers also use the skills inside their current role, as most of our residents do.

How long does it take to learn?

Long enough to build one real tool. In the Residency that is four weeks, alongside full-time practice. Foundations, one week, is the start.

Foundations is $1,525. The AI Residency is $5,850. Many employers pay.

Legal engineering

What is legal engineering?

Legal engineering is a lawyer building the tool their own work needs. A legal engineer knows which part of a legal task AI can take, builds the tool that takes it, and checks that it gives an answer a careful lawyer would sign.

The word is not new. Law firms and legal AI companies have hired legal engineers for years, mostly people who sit between lawyers and software teams. What has changed is that frontier AI tools let a practising lawyer do the building themselves, without a software team and without learning to code first.

What a legal engineer actually does

Finds the work AI can take. Not “use AI more”, but one named task: the first draft of an 8-K, a regulatory read across five markets, a check of counsel’s memo against the product it describes.
Builds the tool. With today’s AI tools, a lawyer can build a working app, an assistant or a model in weeks, not months.
Proves it works. A legal engineer tests the tool against the answers a lawyer would give, and keeps a lawyer in charge of what goes out.

Built by practising lawyers

These were built in the LegalQuants AI Residency by lawyers who were in full-time practice at the time. Most had never built software before.

Leading Question — cross-examination simulator

Alex · Senior Associate, A&O Shearman

Leading Question: load a hearing bundle, then cross-examine an AI witness out loud. The witness answers only from what they should know, and “take you to exhibit 6” puts the document in front of them.

“Me, a mug with no technical know-how whatsoever, can build in two and a half weeks Leading Question.”

Disclosure Desk — Form 8-K drafting

Monica · Special Counsel and Firmwide Director of Legal Skills Training, Sheppard Mullin

Disclosure Desk starts an 8-K from the issuer’s own last filing on EDGAR, tracks the filing deadline and exports a Word blackline. Every AI suggestion stays marked until a lawyer accepts it.

“…got paired with the best mentor ever who really helped through this process, and what I can say today is that I did it.”

An image-similarity model for IP cases

Justin · Transactional Practice Innovation Lead, Jackson Walker

A computer-vision model, built and trained from the ground up, that pairs the images in past IP cases with the court’s analysis. On his benchmark it scored 84.23%, against 74.58% for Fable and 59.36% for Astra; first place in the cohort.

“What I think the cohort did really well is that it allows people to find something that they’re innately curious about… and to grow through that.”

Laply — UK and EU legislation readiness

Chris · Head of EMEA Commercial Legal, Zscaler

Laply checks whether a UK or EU law applies to a company, then builds a readiness assessment of its obligations. He built it after a general AI tool missed NIS2’s core security obligation.

“This was the first time I’d ever seen a terminal window outside of the movie.”

Three ways to learn it

Self-paced courses

What you get: The vocabulary: what AI is, its risks, how to prompt
Format: Online, on your own
Good for: Getting started, CLE credit

University executive programmes

What you get: A strategy view for leaders, with case studies and some prototyping
Format: In person, usually one to two weeks, by application
Good for: Leaders setting AI strategy for a firm or legal team

Mentored building

What you get: Your own tool, built and tested on your own work
Format: Live online, with a lawyer who builds
Good for: Lawyers who want to build, not just understand

LegalQuants teaches the third way, in two steps:

Foundations is one live week on how frontier AI tools work, where their ceiling is, and what legal work they can take. foundations.legalquants.com
The AI Residency is four weeks of building your own tool, matched one-to-one with a senior lawyer who builds. It ends with a Demo Day. residency.legalquants.com
