Principle Engineer

Principal Software Engineer (.NET / AWS)

£90,000+ per annum IT Function Manchester / Hybrid

Shape the Future of Cloud-Native Fintech Engineering

Are you ready to step into a role where you can drive architectural excellence, solve complex engineering challenges, and influence technical direction at scale?

We're looking for a Principal Software Engineer to join a high-performing engineering function, playing a critical role in delivering scalable, cloud-native fintech platforms that support a rapidly expanding digital product suite.

This is a senior individual contributor role for someone who thrives on deep technical problem-solving, system design, and raising engineering standards across teams.

What You'll Be Doing

Owning Architecture & Technical Direction

Design and build scalable, distributed systems using .NET (C#)

Define and evolve system architecture across AWS cloud environments

Lead on complex technical challenges and system design decisions

Ensure platforms are built for performance, scalability, security, and resilience

Driving Engineering Excellence

Act as a go-to technical expert within the engineering function

Champion best practices, clean code, and modern engineering standards

Contribute to architectural discussions and guide technical direction without line management responsibility

Support and influence the wider engineering team through knowledge sharing and technical mentorship

Hands-On Delivery & Innovation

Contribute directly to coding, design, and delivery of key systems

Work across the full lifecycle - from design through to deployment and optimisation

Drive improvement across CI/CD, DevOps, and cloud-native practices

Collaborate closely with Product and Engineering teams to deliver high-impact solutions

What Makes You Stand Out

You are a highly experienced engineer with a passion for hands-on development, architecture, and solving complex technical challenges.

Extensive experience with .NET / C# in large-scale, complex systems

Strong hands-on expertise with AWS cloud platforms (essential)

Proven experience designing scalable, distributed and microservices architectures

Deep understanding of APIs, system design, and integration patterns

Strong experience within DevOps, CI/CD, and modern engineering practices

Ability to influence technical direction through expertise rather than authority

Desirable Skills

Experience with Docker, Kubernetes, or containerisation

Knowledge of event-driven systems and architectures

Exposure to front-end technologies (React / Angular)

Experience within fintech or regulated environments

Why This Role Stands Out

£90,000+ salary depending on experience

Opportunity to shape architecture and engineering direction at scale

Remain hands-on while working on complex, high-impact systems

Work on cloud-native fintech platforms with real-world impact

High level of technical autonomy and influence

Strong engineering culture with a modern technology stack

Hybrid working in Manchester

If you're looking for a role where you can stay deeply technical, influence architecture, and make a lasting impact without moving away from engineering, we'd love to hear from you.
