Join a mission-driven AI health tech startup that is already improving the lives of millions, focusing on automating a physically admin-heavy workflow. The products you build will help care providers by automating data sifting, enabling quicker decision-making.

This is a seed-stage startup, seeking strong software engineers who want to own their products and solve complex problems. You should be excited about AI’s potential to enhance lives.

What’s Required:

  • 3+ years of experience developing across the stack in C# or Python
  • Proficiency with a modern JS front-end framework (React, Vue.js, Angular)
  • Experience with cloud architecture (Azure, AWS, or GCP)
  • Deep knowledge of relational databases
  • Degree in Maths, Engineering, Computer Science, or related field
  • Proven experience building scalable systems/applications in startups or greenfield projects within larger organizations
  • Strong problem-solving skills and autonomy

What Will Set You Apart:

  • Experience working with LLMs in production

Logistics:

  • £80,000-110,000 depending on experience + equity
  • London office 3x per week

Process:

  • Intro with the CEO (30 mins)
  • On-site technical interview + culture discussion (2 hours)
  • Offer

If you’re excited to work on meaningful problems in a fast-paced environment, please apply.
