You will own and build customer facing features end to end, working primarily in React across the frontend while reaching into Python backend services and AWS infrastructure as needed. You will also contribute to the core platform as the product scales, not just the layer on top of it.
This is not a narrowly scoped UI role. You are close to the product, close to the customer, and close to the architecture.

Building customer facing features in React, from design through to delivery
Working into Python backend services to complete features end to end
Using AWS to deploy, support, and iterate on production capabilities
Collaborating with platform engineers to fold new features back into the core product
Shaping patterns, structure, and engineering standards as the system grows
Taking ownership of reliability and performance in a production environment

5 or more years building production SaaS systems as a Software Engineer
Strong React fundamentals with real production experience
Working ability in Python backend development
Cloud experience, ideally AWS
Comfortable in early stage environments with high ownership and some ambiguity
A production first mindset, reliability and maintainability over speed
Nice to haves
Experience in data intensive or real-time systems Exposure to API driven architectures and modern frontend patterns
Previous work on customer facing SaaS platforms
Salary: £70,000 to £80,000 plus benefits
No sponsorship available.
