Remote | Contract / Freelance | Ongoing Engagement
About Matchspace
Matchspace is a growing SaaS platform helping tennis, padel, squash and pickleball clubs increase participation and simplify club management.
Used by clubs across the UK, Matchspace provides tools for running leagues, ladders, tournaments, events and player engagement activities. We are continually improving the platform and are looking for an experienced developer to join us on an ongoing basis.
The Opportunity
We are looking for a practical and experienced software developer who can work within an existing product and help drive the next stage of development.
Our platform is already established and built using .NET and React Native. This role is focused on understanding, maintaining and enhancing the current system rather than building a new product from scratch.
You will work closely with the founders to develop new features, improve existing functionality, resolve technical issues and help introduce AI-assisted development processes that allow us to move faster and build better software.
This is a long-term opportunity for someone who enjoys product development, problem-solving and working as part of a small, ambitious team.
Key Responsibilities
• Understand and work within the existing Matchspace codebase
• Develop new features across web, mobile and backend systems
• Maintain and improve existing functionality
• Investigate and resolve bugs and support issues
• Work with .NET backend services and APIs
• Work with the React Native mobile application
• Collaborate with founders to scope, estimate and prioritise development work
• Review and improve system architecture where appropriate
• Participate in testing, deployment and release processes
• Provide ongoing monthly support and maintenance
• Help implement modern AI-assisted development workflows
• Identify opportunities to use AI to improve both development efficiency and product capabilities
• Review, validate and extend AI-generated code to production standards
Required Skills and Experience
• Strong commercial experience with .NET development
• Strong commercial experience with React Native
• Experience working within established software products
• Experience understanding and extending existing codebases
• Strong knowledge of API development and integrations
• Experience using Git and collaborative development practices
• Excellent debugging and problem-solving skills
• Experience supporting live production applications
• Ability to work independently and manage workload effectively
Desirable Skills
• Experience with Microsoft Azure
• Experience deploying and maintaining mobile applications
• Experience with SaaS platforms
• Experience integrating third-party services and APIs
• Experience using AI coding tools such as ChatGPT, Claude, GitHub Copilot, Cursor or similar
• Experience building AI-powered features into software products
• Experience working with small businesses or startup environments
What We Are Looking For
We are looking for someone who can quickly become productive within an existing product.
The ideal candidate will be comfortable reading and understanding existing code, making sensible improvements, and delivering features without creating unnecessary complexity.
They should be excited by the opportunities AI presents for software development and willing to help us establish efficient AI-assisted development processes going forward.
Most importantly, we want someone who is reliable, communicative and interested in building a long-term working relationship.
Engagement
We are seeking an ongoing relationship rather than a one-off project.
The role is expected to include:
• Ongoing monthly support and maintenance
• Feature development
• Technical improvements
• AI integration projects
• Product roadmap delivery
Hours can be flexible and agreed based on experience and availability.
To Apply
Please send:
• A summary of your relevant experience
• Examples of .NET projects you have worked on
• Examples of React Native projects you have worked on
• Details of any AI-assisted development experience
• Your availability
• Your preferred hourly or monthly rate
We are particularly interested in hearing from developers who have experience working with AI-generated code and who understand how to combine AI tools with sound software engineering practices to accelerate product development while maintaining quality.
