About the project: We are developing a digital platform for managing equestrian shows, qualifiers, and exhibitions.

• Deep understanding of microservices architecture.
• Knowledge of cloud services (AWS).
• Experience in developing APIs for third-party integrations (payment gateways, external data providers).
• Practical experience with AI-assisted development tools (Claude Code, GitHub Copilot, Cursor, Codex, or similar) — ability to effectively use AI for code generation, refactoring, and review.

Responsibilities:
 

• Development and enhancement of core platform modules: event and class management, entry processing, user registration, and profile/entity management (horses, riders, owners).
• Integration with payment systems (Opayo/SagePay) and external data providers for results and personal data verification.
• Building role-based admin panels for show administrators, organization admins, and gate staff.
• Implementation of QR-code based access control and ticket validation logic.

• Code reviews and ensuring code quality.
• Collaboration with developers, QA, analysts, and product team.
• Participation in planning and sprint reviews.
• Designing scalable backend services to support multi-organization environments with isolated data access.
