• Develop integrations with payment providers, gaming providers, sportsbook feeds and other external systems
• Implement authentication, authorisation and role-based access control
• Troubleshoot issues across frontend, backend, database and integration layers
• Write clean, testable code, plus unit and integration tests
• Participate in architecture, design and code reviews
• Optimise application performance, reliability and scalability, and resolve production issues
• Contribute to technical documentation and development standards

• Experience with modular Angular architecture, reusable components and state management patterns
• Experience with authentication and authorisation, including JWT/OAuth, and web security fundamentals
• Experience writing unit and integration tests, plus frontend performance optimisation and debugging
