Principal .NET Developer

talego • manchester, north west england, uk • 4d ago

Principal Back-End Developer

Up to £80,000 | Manchester (Onsite) | HealthTech | Purpose-Led Mission

You’ve built systems that scale. Led by example. Solved problems others didn’t even see coming.

Now you’re looking for something bigger — a place where your code and your leadership genuinely make a difference.

This HealthTech company is reshaping how the NHS delivers care through smarter digital platforms, giving millions of people faster, fairer access to healthcare.

They’ve brought all development in-house, built a brand-new engineering team, and proved it works. Now, they’re ready to level up, and that’s where you come in.

The role

As Principal Back-End Developer,you’ll be the technical backbone of a product used by over 13 million people across the UK and Ireland.

This isn’t a “hands-off” leadership gig, it’s hands-on impact.

You’ll be architecting systems, mentoring engineers, and driving the standards that define what great looks like.

What you’ll be doing:

Leading by example, designing and building scalable systems with C#, .NET Core, and Azure.
Shaping architecture and product direction across multiple platforms.
Coaching and mentoring your peers — helping good engineers become great ones.
Embedding quality through TDD, CI/CD, and clean coding principles.
Working closely with product and design to turn big ideas into elegant, practical solutions.

What you’ll bring:

Deep technical expertise in C#/.NET Core and cloud-based architecture (Azure preferred).
A passion for clean, reliable, and maintainable code.
Strong judgment: you know when to be pragmatic and when to push for perfection.
A collaborative spirit: mentoring, pair programming, and leading by example.

Why this one’s different

This isn’t about “enterprise software.”

It’s about building technology that keeps people healthy, connected, and cared for.

You’ll join a team that values autonomy, curiosity, and doing things the right way. The culture’s grounded in trust, purpose, and a shared belief that great engineering can improve lives.

If you want your next role to mean something, not just for your career, but for millions of people, this is the one.
