Stackfix is a high-growth AI implementation firm backed by Tier 1 investors.

You will bridge the gap between frontier AI and real-world business operations. Instead of building generic SaaS tools, you will deploy production-grade AI systems for PE funds and manufacturers. Working directly with repeat founders who sold companies to TikTok, you will own the end-to-end process of transforming workflows and growing client profits.

Location: London, UK

Why this role is remarkable:

  • Learn directly from two exited founders (including a former TikTok engineering leader) in a high-intensity, apprenticeship-style environment.
  • Gain deep expertise in frontier AI by building production systems that handle real transactions, rather than just experimenting with tutorials.
  • Enjoy significant variety and ownership, shipping impactful solutions across diverse industries such as logistics, e-commerce, and private equity within 4-9 month cycles.

What you will do:

  • Build and deploy sophisticated AI systems and full-stack software that manage high-volume production workflows for enterprise clients.
  • Interface directly with leadership at client sites to scope workflows and present high-impact AI transformation strategies.
  • Own the full product lifecycle from initial technical discovery and architecture to shipping production-ready systems that generate real revenue.

The ideal candidate:

  • 4+ years of full-stack software engineering experience with a proven track record of shipping production-grade systems.
  • Demonstrates high agency and a passion for building through side projects, open-source contributions, or technical content creation.
  • Exhibits a strong curiosity for business operations and a record of high performance in challenging environments (professional or personal).
