Senior Backend Engineer (Python | AWS)
?? £50,000 per annum
�? Fully Remote – UK Based
?? Permanent, Full-Time

A well-established UK insurance organisation is undertaking a major backend transformation programme, rebuilding a legacy PHP platform into a modern, scalable Python-based architecture hosted in AWS.

This is a senior-level engineering role focused on designing and delivering the next generation backend platform that will underpin future digital products.
The role is heavily Python-focused. PHP knowledge is beneficial only to support understanding of the legacy system during migration — it is not the primary technology moving forward.

The Opportunity
You’ll play a key role in the architecture and delivery of a modern cloud-native backend platform, helping transition core functionality from a legacy PHP estate into a scalable, secure Python environment.
This is a hands-on engineering position with architectural influence — ideal for someone who enjoys shaping technical direction while remaining close to code.

Key Responsibilities

Platform Modernisation
*Architect and develop scalable backend services using Python
*Design and implement secure, well-structured RESTful APIs
*Lead the re-engineering of legacy functionality into modern, cloud-native services
*Contribute to long-term backend architecture decisions
Cloud & Infrastructure
*Design and build solutions within AWS environments
*Apply cloud best practices for scalability, resilience and security
*Contribute to CI/CD pipelines and deployment workflows
*Embed monitoring, logging and observability within cloud-hosted systems
Legacy Transition
*Support phased migration away from the existing PHP platform
*Provide technical oversight during system replacement and integration
*Reduce technical debt while maintaining service continuity
Engineering Leadership
*Participate in technical reviews and architectural discussions
*Promote coding standards and clean architecture principles
*Mentor junior developers where appropriate
*Contribute to Agile ceremonies and cross-functional collaboration
Essential Experience
*Strong commercial experience developing backend systems in Python
*Experience designing and implementing RESTful APIs
*Proven experience building and deploying applications within AWS (e.g. Lambda, ECS, API Gateway, CloudWatch, DynamoDB, Cognito or similar services)
*Experience working in cloud-native or distributed architectures
*Strong understanding of security, authentication and secure API design
*Experience with CI/CD pipelines and modern DevOps practices
*Familiarity with Git-based version control workflows
Desirable
*Working knowledge of PHP (legacy context only)
*Experience modernising or replacing legacy systems
*Event-driven or serverless architecture exposure
*Background within financial services or regulated environments
Why Apply?
*Genuine greenfield-style rebuild within an established organisation
*Senior-level influence on platform architecture
*Cloud-first engineering environment
*Fully remote UK role
*Long-term technology investment roadmap
