Principal Developer

Senior / Principal Software Engineer

Location: Hybrid (Manchester Area)

Are you ready to take your engineering career to the next level by shaping mission critical software in a massive, modernisation programme? We're looking for Senior and Principal Software Engineers to help lead the evolution of a next-generation cloud platform powering globally distributed, high-impact technology solutions.

This is more than a software role. It’s an opportunity to build resilient, scalable cloud services that are used by teams and organisations around the world — all contributing to tech-for-good initiatives that genuinely make a difference. Your decisions will help drive a strategic transformation at scale.

Why This Opportunity Stands Out

• Be part of a high-investment programme modernising a global technology platform
• Build cloud-native applications that serve tens of thousands of users across 100+ countries
• Work in an agile, DevOps-first environment with real autonomy and purpose
• Tackle complex engineering challenges with modern tools, scalable architecture, and continuous delivery
• Collaborate with a passionate team of engineers, architects, and product leaders driving real-world impact

What You'll Be Doing

Whether you’re a Senior ready for more ownership or a Principal keen to lead technically, you’ll:

• Design, build, and scale distributed microservices using C# / .NET on AWS
• Deliver reliable, secure, and high-performance APIs that support critical global workflows
• Help shape engineering practices, define architectural patterns, and embed quality from the ground up
• Guide and mentor other engineers, fostering continuous improvement and technical growth
• Contribute to shared platform services such as tenancy management, notifications, monitoring, and access control

What You Bring

• Proven experience in cloud-first software engineering roles (ideally 5+ years for Senior level)
• Deep knowledge of C# / .NET, and experience building RESTful APIs and microservices
• Hands-on expertise with AWS and modern engineering practices (CI/CD, TDD, SOLID, Agile)
• A problem-solving mindset with the ability to design scalable, maintainable systems
• Strong collaboration and communication skills — and a passion for building better together

Nice to Have (We’ll Support Learning Too)

• Frontend development experience (especially with Angular)
• Experience with Kubernetes, Docker, GitHub Actions, or Datadog
• Familiarity with BDD (Gherkin, SpecFlow), observability tooling, and secure development practices
• Experience working in highly regulated or enterprise-scale environments

What’s In It for You

• Be at the forefront of a massive platform transformation — with freedom to innovate
• Enjoy a hybrid working model, flexible hours, and a people-first culture
• Competitive salary and benefits, including private healthcare, 25 days holiday, pension, gym subsidy, and more
• A clear path for technical progression and dedicated time for personal development

Ready to build technology that reaches around the world — and makes it better?

Apply now and play a leading role in a global transformation journey driven by purpose, scale, and smart engineering.
