Senior Software Engineer | AI Healthcare | Build Tech That Actually Matters

We’re working with a high-growth AI healthcare company building a platform that’s genuinely changing how people move, recover, and live and they’re looking for a Senior Software Engineer to join them at a critical stage of growth.

This isn’t a “maintain legacy systems” role.

You’ll be building core systems from scratch, shipping fast, and seeing real-world impact from day one.

Why this is different:

  • Your code directly improves patient outcomes this is real impact, not vanity metrics
  • Move from idea → production in days, not months
  • Join a small, high-calibre team where every hire matters
  • Zero bureaucracy, high ownership, and full trust to deliver

What you’ll be doing:

  • Designing and building scalable backend systems powering AI-driven healthcare products
  • Working across TypeScript + AWS (serverless architecture)
  • Building clean, developer-first APIs & SDKs
  • Developing high-performance data pipelines for real-time AI insights
  • Owning your work end-to-end from architecture through to deployment

What they’re looking for:

  • Strong experience with AWS + TypeScript (you’re comfortable making architectural decisions)
  • Proven track record building scalable, production-grade backend systems
  • Experience with APIs, SDKs, and real-time data processing
  • Someone who cares about performance, reliability, and clean design

What kind of person thrives here:

  • Product-minded - you think about users, not just code
  • Communicative - you challenge ideas and collaborate well
  • Fast-moving - you like shipping, not overthinking
  • Mission-driven - you want to work on something that actually matters

If you’re interested (or just curious), drop me a message - happy to run through it.
