Salary
£85K Equity
Company Description
Stackfix – High growth AI implementation firm backed by Tier 1 investors
Job Description
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). Next steps Visit our website. Click Talk to Jack .
