We’re supporting a UK SaaS business building a new European engineering team to deliver a major product modernisation programme.

We’re looking for hands-on Software Engineers to join a cross-functional squad and take ownership of features and technical improvements from development through to production.The initial project will focus on modernising a legacy SaaS platform, rebuilding key areas of the frontend in React and improving existing services, APIs and integrations.

The environment is highly AI-enabled, with AI development tools embedded throughout the software development lifecycle. We’re therefore looking for engineers who have already adopted AI-assisted development or are genuinely enthusiastic about working this way.

What you’ll be doing• Build and improve features across a large existing SaaS application• Help modernise and rebuild legacy frontend functionality in React• Take ownership of features and technical improvements through to production• Design clean, maintainable components with clear responsibilities and interfaces• Work with existing services, APIs and integrations• Write clean, readable and maintainable production code• Write and maintain automated tests covering core functionality and edge cases• Contribute to technical discussions, code reviews and engineering ceremonies• Work closely with Product, Design, QA and Engineering stakeholders• Work within established CI/CD, version control and release processes• Use monitoring, logging and observability tools to investigate production issues• Identify blockers, dependencies and technical risks early• Use AI-assisted development tools across coding, testing, debugging, refactoring and documentation• Maintain strong standards around testing, security, reliability and production quality

• What we’re looking for• Strong commercial software engineering experience• Strong experience with React and modern frontend development• Experience building and shipping software into production• Experience working with APIs and modern web architectures• Experience working with existing or legacy applications and improving them over time• Good understanding of software design and component architecture• Strong problem-solving and debugging skills• Experience with automated testing and code reviews• Strong understanding of CI/CD and modern development workflows• Exposure to cloud-based production environments• Experience working in Agile, cross-functional product teams• Strong communication and collaboration skills• Comfortable working in environments with limited documentation and taking ownership quickly• Experience using AI coding tools such as Claude, Cursor, GitHub
