Founding Fullstack Engineer

Hybrid – 2–3 days/week in London (near Blackfriars station)

£80k–£100k + equity + startup perks

Neulinx is hiring on behalf of a stealth-mode startup operating at the intersection of healthcare, fintech, and AI. We’re looking for a Founding Fullstack Engineer to help build their core product from scratch. This is the startup’s first technical hire — an opportunity for someone who wants full ownership, fast pace, and real impact.

You’ll work directly with the technical founder (ex-healthtech scaleup) to design, build, and ship the MVP. It’s a hands-on engineering role now, with a clear path to a leadership position as the company grows.

What You’ll Do

• Architect and build the core platform — backend, frontend, infrastructure
• Own scalability, performance, security, and deployment
• Work side-by-side with product and ops to solve meaningful problems fast
• Shape engineering culture, processes, and future team structure

• What We’re Looking For

  • 4+ years of fullstack development experience, ideally in startups or product-led teams
  • Strong backend expertise, especially with Node.js
  • Solid frontend skills — Vue.js, React, or TypeScript
  • Proven experience building and maintaining production systems
  • Bias toward shipping, iterating, and solving problems — not just perfecting code
  • Strong communicator who’s comfortable in an unstructured, high-ownership environment

  
  

  Nice-to-Haves

  • Background in fintech, healthtech, or AI-powered products
  • Experience working with LLMs, chat interfaces, or emerging AI tools

  
  

  Why It’s a Unique Opportunity

  • You’ll own the build — from architecture to first users
  • You’ll solve real-world complexity in healthcare and finance
  • You’ll have early equity in a venture with long-term growth potential
