AI-Assisted Development (MANDATORY)
Experience with Claude Code, Cursor, GitHub Copilot, or similar AI coding tools is required for this role. You must be actively using these tools in your daily workflow for code generation, debugging, and refactoring. In your application, you will need to explain your current setup and demonstrate how you integrate AI tools into your development process.
Experience Requirements
Essential Experience:
Highly Desirable: Experience with multi-tenant applications, Clean Architecture patterns, background job processing systems, push notifications and webhooks, cloud services (AWS/Azure/GCP), Docker, CI/CD pipelines (CircleCI or similar), Redis caching, Firebase services (Auth, FCM, Realtime Database), and monorepo management.
You Should Have: Built and shipped at least 2 production full-stack applications including at least 2 React Native mobile apps to both iOS and Google Play stores. Experience with e-commerce or booking platforms is particularly valuable. You should be comfortable working with complex database schemas, debugging production issues under pressure, debugging cross-platform mobile issues, and integrating multiple third-party APIs. Managing multiple environments (development, staging, production) should be second nature to you.
Required Competencies
Technical Skills: You need to be able to debug complex multi-tier applications independently, write clean and maintainable code, and identify performance bottlenecks across backend, web, and mobile platforms. You should be quick to learn new technologies and frameworks, and comfortable making architectural decisions. A well-established AI-assisted development workflow is essential for this role. You must be capable of troubleshooting native iOS and Android issues when they arise.
Communication: Strong written and verbal English is required. You'll be writing technical documentation, collaborating effectively with a remote team, and participating in code reviews. You must be self-motivated and capable of working with minimal supervision.
Professional Approach: We need someone who takes ownership of features from conception through to deployment, including managing mobile app store releases. You should proactively identify issues before they become problems, consistently deliver quality work on time, and be comfortable working across different parts of the stack (backend, web frontend, mobile). Attention to edge cases and thorough testing is important to us.
What We Offer
This is a fully remote position with flexible working hours, though you'll need to maintain core overlap with UK business hours (GMT/BST). You'll be working on a live production platform that serves car wash businesses across the UK, using modern technologies including .NET 8.0, Angular 19, React Native, and various cloud services.
We support an AI-assisted development environment where tools like Claude Code and Cursor are part of our standard workflow. You'll gain hands-on experience with Clean Architecture, Domain-Driven Design, and enterprise-level patterns while working on a real multi-tenant SaaS application with both web and mobile components.
The role involves meaningful work with major integrations including Stripe, Firebase, and AWS. You'll be working in a monorepo structure with shared code libraries across mobile and backend. This is a long-term position with genuine opportunities for professional growth
