Principal Software Engineer

Company: TechNET IT Recruitment Ltd
Apply for the Principal Software Engineer
Location: Cambridge
Job Description:

We’re exclusively partnering with a globally recognised technology organisation undergoing a significant engineering transformation. As they continue to invest in modern software delivery, cloud technologies and AI‑enabled engineering practices, they’re looking to appoint a Principal Engineer / Technical Lead to help shape the future of their digital platforms.

This is an opportunity to join a collaborative engineering environment where you’ll influence technical direction, mentor development teams and help deliver products used by millions of users worldwide.

The Opportunity

This is not a traditional architecture role.

We’re looking for an experienced software engineering leader who enjoys staying close to technology while driving technical direction across a major product area.

You’ll act as the bridge between Product, UX and Engineering, translating business objectives into scalable, maintainable software while helping engineering teams deliver with confidence.

You’ll have the freedom to remain hands‑on where it adds value – reviewing code, solving complex technical challenges and helping engineers overcome blockers – while influencing architecture, engineering standards and delivery strategy.

What You’ll Be Doing

  • Own the technical direction for a major product area.
  • Shape software architecture for scalable cloud‑based platforms.
  • Translate product requirements into clear engineering solutions.
  • Provide technical leadership across distributed engineering teams.
  • Mentor engineers and champion engineering best practice.
  • Improve software quality, delivery and operational excellence.
  • Influence technology selection, tooling and development standards.
  • Drive the adoption of AI‑assisted software engineering practices.
  • Collaborate closely with Product Managers, UX Designers and Engineering Leadership.

What We’re Looking For

You’ll likely be working today as a:

  • Principal Engineer
  • Technical Lead
  • Hands‑on Engineering Manager

You’ll bring experience in:

  • Designing and delivering large‑scale software platforms.
  • Modern cloud‑native architecture.
  • TypeScript and Node.js.
  • React or Vue.js.
  • CI/CD, DevOps and containerised environments.
  • API‑first and event‑driven architectures.
  • Leading engineering teams through influence rather than formal line management.
  • Working closely with Product and business stakeholders.
  • Modern AI‑assisted software development tools and workflows.

About You

You’ll enjoy solving difficult engineering problems and balancing technical excellence with pragmatic delivery.

You’re someone who naturally takes ownership, mentors others and enjoys improving the way engineering teams work. You’ll be comfortable working across multiple disciplines and thrive in an environment where collaboration and continuous improvement are highly valued.

What’s On Offer

  • Negotiable salary, based upon experience and expectations
  • Performance bonus
  • Life assurance
  • Hybrid working (2 days per week in Cambridge)
  • Modern engineering environment with significant investment in AI‑enabled software development
  • The opportunity to influence engineering strategy within a globally respected organisation

If you’re looking for a role where you can combine technical leadership, architecture, hands‑on engineering and genuine ownership, we’d love to hear from you.
