"Work on a real AI product… not a marketing gimmick"


An AI powered fraud detection system is making waves within the financial sector. Already being used by several unicorn fintechs, this YC backed team are now looking to grow with a number of hires to formulate their founding engineering team. One of those hires, maybe you, will be focused on developing our core platform. The role is mostly backend focused (80%) using Node and TypeScript with some React (20%) for the UI. As we are mostly a backend product, working with APIs and connecting the LLMs to our clients, we also need someone who can work in a serverless architecture, using AWS.


The founders are experienced fintech specialists having worked with someone the most exciting teams from Europe. Now we turn out attention to hopefully the next big B2B AI product, and your chance to join awaits.


Your profile:


  • 5+ years of experience in development, ideally working within early-stage companies or your own business.

  • Experience handling end-to-end projects as a solo developer.

  • Frontend: React  Backend: Node/TypeScript / Infrastructure: AWS

  • Experience developing architecture and system design.

  • Adopt a build it, run it approach.

  • Exposure to SaaS or Enterprise products is ideal.

  • A genuine interest for AI and LLMs, ideally with hands on experience.

  • Excellent communicator who can work with customers.


Benefits of the role:


  • Hybrid work model with a central London office space.

  • Ownership of how the core product will look, working directly with the CTO.

  • The chance to work in a small team that has already gained customers, backed by YC and has a 2 year runway.

  • Excellent base salary + equity package.
