London, United Kingdom£60k + Equity

AI Engineer at Stackfix

Are you ready to build AI that actually moves the needle for the global economy? Stackfix is looking for an AI Engineer to join their London team and work directly alongside two-time exited founders. Instead of building another generic chatbot, you’ll deploy frontier AI into the heart of real businesses—from private equity funds to manufacturing plants. With a £60k salary, significant equity, and a 'masterclass' in entrepreneurship, this is the ultimate launchpad for anyone looking to master production-grade AI and eventually start their own company.

Overview

Role overview

Join two-time exited founders to bridge the gap between frontier AI and real-world business operations. You will build and deploy production-grade AI systems for PE funds, manufacturers, and logistics firms. This role offers a unique training ground for future entrepreneurs, focusing on solving high-value problems that generate real earnings for global companies.

Responsibilities

What you will do

  • Design, build, and deploy end-to-end AI software systems that automate complex workflows for enterprise clients like PE funds and distributors.
  • Participate in the full project lifecycle by visiting client sites, joining leadership calls, and presenting technical solutions to business stakeholders.
  • Take full ownership of production-ready code that processes hundreds of daily transactions or reviews thousands of records per hour 24/7.

Candidate profile

Who this is a fit for

  • Proven track record of building useful software, evidenced by high-quality side projects, professional work, or university research that solved a real-world problem.
  • Strong business curiosity and a desire to understand commercial value drivers like EBITDA while working directly with client leadership teams.
  • High-performance mindset with a history of excellence in any field (e.g., competitive sports or arts) and a hunger to master AI tooling rapidly.

What makes it remarkable

Why this role is remarkable

  • Learn directly from two successful exited founders (Jukedeck/TikTok and HR tech) through daily side-by-side collaboration and high-stakes client engagement.
  • Gain deep expertise in frontier AI by building production systems that handle real transactions, moving beyond the hype of simple chatbots or wrappers.
  • Rapid professional growth via exposure to diverse industries, from private equity to manufacturing, providing better entrepreneurial preparation than years at a single-product company.
