Principal Software Engineer (.NET / AWS)

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
• 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

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.
