Python Developer

Overview

A fast-scaling Fin Tech is expanding its engineering team and is hiring a Python Software Engineer to help build and scale critical backend systems that power a high-volume, customer-facing platform operating across the UK.

This role is focused on backend development
, working on services and data-intensive systems that sit at the core of the platform. You’ll have real influence over how systems are designed, built, and evolved as the business continues to scale.

• Design, build, and maintain production-grade backend services in Python
• Develop and evolve APIs, data models, and service integrations
• Work on systems that handle high throughput, reliability, and performance at scale
• Take ownership of features and services from design through to production support
• Contribute to architectural decisions around services, data, and cloud infrastructure
• Collaborate with product, data, and engineering teams to deliver robust solutions
• Write clean, well-tested, and maintainable code
• Prioritise simple, scalable solutions over unnecessary complexity
• Use modern tooling (including AI-assisted development where appropriate) to improve quality and speed of delivery

• Testing: pytest, automated testing practices
• Cloud & Infrastructure: AWS and/or GCP, Docker, Terraform
• CI/CD: Git Hub Actions, automated pipelines

No one is expected to know everything — strong backend fundamentals and a willingness to learn matter most.

• Small, cross-functional teams with shared ownership
• Continuous deployment with automated testing and pipelines
• Strong focus on reliability, observability, and system health
• Cloud-native systems built for scale and resilience
• Decisions driven by real usage data and customer needs

• Inclusive, collaborative teams where everyone’s input matters
• Low-ego, supportive environment with high engineering standards
• Space to propose ideas, challenge assumptions, and improve systems
• Emphasis on learning, curiosity, and long-term maintainability
• Focus on building robust, well-designed software — not just shipping quickly
