PLATFORM ENGINEER

UP TO £140,000

LONDON

This is a unique opportunity to join a well-funded AI startup at a pivotal stage of growth. You'll become one of the earliest engineering hires, taking ownership of a cutting-edge AI platform and helping shape the future direction of both the product and engineering function as the business scales.

THE COMPANY

Our client is an early-stage AI business backed by significant investment and focused on helping enterprise organisations better understand customer behaviour through advanced AI technologies. With several large financial services organisations already engaged, the business is now moving from Proof of Concept into commercial deployment and is looking for an experienced engineer to help build and scale the platform.

THE ROLE
  • Own and scale a cutting-edge AI-powered platform used by enterprise customers
  • Build products around LLM and AI capabilities rather than developing the underlying models
  • Design and develop scalable backend systems and APIs
  • Work directly with founders and senior stakeholders on product direction and technical decisions
  • Take significant ownership of architecture, delivery and platform evolution
  • Help shape the future engineering function as the company grows
YOUR SKILLS AND EXPERIENCE
  • Strong experience as a Product Software Engineer
  • Proven experience building and launching LLM-enabled products from 0-1
  • Strong backend engineering experience, ideally with Node.js and TypeScript
  • Experience building API-first products and scalable platforms
  • Comfortable operating in early-stage startup environments
  • High levels of ownership, autonomy and commercial awareness
  • React experience would be advantageous but is not essential
  • FinTech or Financial Services experience would be beneficial
SALARY AND BENEFITS
  • Up to £140,000 base salary
  • Equity package
  • Hybrid working model
  • Opportunity to be a key early engineering hire
  • Significant ownership and influence over product development
  • Direct access to founders and leadership team
