Full Stack Engineer (React, TypeScript, Node.js, AI)


Fully Remote (UK) | £90k + Equity


The Opportunity

We’re partnered with one of the fastest growing AI startups in the UK, building a category-defining platform that is transforming how large enterprises operate.

This is a genuinely AI-first business, where AI is at the core of the product, not an add-on. The platform leverages AI agents, automation, and real-time data systems to solve complex, high-value problems at scale.


With strong backing, rapid customer growth, and expansion across Europe, they’re now looking to bring in a high-calibre Full Stack Engineer to help shape the next phase of the product.


What You’ll Be Working On

  • Building and scaling modern, responsive frontends using React and TypeScript
  • Developing robust backend services in Node.js
  • Designing and integrating AI-driven features and workflows into the core product
  • Working closely with product and ML teams to bring AI capabilities into user-facing features
  • Owning features end-to-end, from concept through to production


Tech Stack

  • Frontend: React, TypeScript
  • Backend: Node.js
  • AI/ML: LLM integrations, AI agents, data pipelines
  • Infrastructure: Cloud-native architecture (AWS/GCP), APIs, microservices


What They’re Looking For

  • Strong experience with React and TypeScript
  • Solid backend experience with Node.js
  • Experience building scalable, production-grade applications
  • Exposure to AI or LLM-based products, or strong interest in moving into this space
  • Comfortable working in a fast-paced, high-growth startup environment
  • Strong product mindset, not just coding to spec


Nice to Have

  • Experience integrating with LLM APIs or building AI-powered features
  • Background in data-heavy or workflow-driven products
  • Experience in high-growth startups or scale-ups


Package

  • Salary up to £90,000
  • Equity in a fast-scaling company
  • Fully remote within the UK
  • High ownership, high impact role


Why This Role?

  • Join a top-tier AI startup early in its scaling journey
  • Work on real AI products, not prototypes
  • High ownership and ability to shape the product
  • Strong engineering culture with ambitious growth plans
