Founding Applied AI Engineer

Company Description: High-growth legal tech startup

Job Description:
As a Founding Applied AI Engineer, you will build the next generation of AI-driven legal tools, focusing on automating complex contract workflows. Working directly with the CTO, you will own technical buildouts end-to-end and develop production-grade ML models. This is a high-impact role at a well-funded startup rapidly scaling its revenue and product.

Location: San Francisco, USA and London, UK

Why this role is remarkable:

  • Join as a founding team member with direct exposure to scaling an AI startup from its earliest stages.

  • Work at a company backed by top-tier VCs that has already achieved significant revenue growth and market traction.

  • Solve complex technical challenges in a trillion-dollar industry ripe for AI-driven transformation.

What you will do:

  • Design and deploy machine learning models specifically optimized for production-level legal document processing.

  • Partner with the CTO to lead customer-facing technical implementations and full-stack product features.

  • Own the entire lifecycle of complex systems, from initial architectural reasoning to identifying failure modes.

The ideal candidate:

  • Possesses strong computer science fundamentals and experience training ML models for production use-cases.

  • Demonstrates high personal agency and the ability to drive projects to completion with limited direction.

  • Thrives in a fast-paced, demanding environment and is eager to progress faster than their industry peers.

Who are Jack & Jill?
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
