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.
