Principal Software Engineer

Principal Engineer - Healthtech Scaleup

What if your next role wasn’t just about code but about legacy?

You’ve probably been the go-to person for solving technical chaos more than once. You’ve steadied shaky architectures. Made sense of complex systems. Calmed down product teams with confident decisions made under pressure. But maybe now, you’re looking for something more.

A place where you can:

Work on a product used by over 30 million people globally

Take a strategic seat at the table, working alongside engineering and product leaders

Guide multiple squads through architectural decisions and technical challenges

Leave your mark on how software is built — and on who builds it

The mission?

To make healthcare simpler and more accessible through beautifully designed SaaS products. You’ll help shape the platform and its future, influencing tech strategy, engineering culture, and delivery at scale.

You’ll join a remote-first team (UK-based, with quarterly meetups), delivering changes to production over 100 times a month. Speed and safety go hand in hand here — supported by a mature, CI/CD-first mindset.

The Tech

• Ruby, Rails, Ember, JavaScript, Postgres, AWS
• With exposure to Node.js, TypeScript, C#, and .NET in other squads
• And emerging AI tooling already being trialled across the organisation

What you’ll do:

• Work closely with the Director of Engineering and EMs to diagnose and fix systemic tech issues
• Set technical direction across squads, with real influence over product decisions
• Design systems with scale, reliability, and security in mind
• Champion engineering excellence - from architecture to AI experimentation

Who you are:

You’re already a Principal, Staff, or Lead Engineer working on complex SaaS platforms. You don’t just understand architecture — you roll up your sleeves and build.

You’ve guided squads, influenced strategy, and bridged the gap between business needs and engineering priorities.

You’ve worked with Ruby/Rails, but you’re curious beyond your comfort zone. And you don’t need micromanaging — you thrive on autonomy.

The offer:

• £120,000 base (possibly more for the right person)
• 10% bonus
• 25 days holiday + birthday off
• Private healthcare
• 5% pension contribution
• Flexible, remote-first culture with meetups each quarter

What’s next?

• Initial Zoom call (1 hour) with Director of Software Engineering
• Final stage (2 hours) with engineering leadership — including a collaborative whiteboard session

This isn’t just another principal role.

It’s your chance to shape the future of a product — and an engineering organisation — that’s changing lives at scale.
