Job description

Python Developer / Backend Software Engineer (Python C# AI) London / WFH to £100k

Are you a Python Developer with a strong knowledge of software engineering best practices and system design?

You could be progressing your career in a senior, hands‑on Python Developer role at a global reinsurance group, building the technology platform behind a diverse portfolio of insurance products used across its international businesses.

The technology team is small, agile and heavily focused on greenfield development, giving you the opportunity to have real influence over architecture, engineering practices and how AI is embedded into the software development lifecycle.

As a Python Developer, you'll be an individual contributor working primarily on backend and cloud-native development. A major part of the role will be exploring how AI can improve both engineering productivity and the products themselves - using tools such as Claude alongside strong software design principles, patterns and engineering best practice.

Location / WFH:

You’ll join colleagues in plush City offices with onsite gym and barista, three days a week, with flexibility to work from home the other two days.

About you:

• You have strong backend software engineering skills, with Python, C# development experience would also be of benefit but not essential
• You have a strong knowledge of Computer Science fundamentals such as OOP, multithreading, Design Patterns and are comfortable with system design
• You understand what makes a good frontend and how to ensure connectivity between front and backend systems, React or Angular skills preferred
• You have a good understanding of cloud native architectures (Azure / AWS), event driven systems, microservices, CI/CD, Terraform, Kubernetes, Docker
• You're keen to use and adopt more AI into processes and the product, you understand "milestone development" and what good system design looks like, how to get the optimum results from AI with proper use of design patterns and best practices - they use Claude but open to experience with other tools
• You're collaborative with great communication and problem solving skills, ideally with experience in a start-up / small team environment

What's in it for you:

As a Python Developer you will receive a competitive package:

• Salary to £100k
• Bonus
• Pension, Income Protection, Life Assurance, Critical Illness Cover, Employee Assistance Programme
• Company Share Scheme
• Enhanced paternity leave and benefits
