This role is fundamentally a Spring Boot-based backend engineering position, responsible for building scalable, production-grade services that manage companies, users, vehicles, devices, positions, trips, alerts, geofences, and reporting capabilities.

The engineer will work within a Spring Boot microservices architecture, ensuring high performance, strong domain consistency, and robust business rule enforcement across the system.

• Implement core fleet features including:
  • Trip history management
  • Alert rules engine
  • Geofencing logic
  • Fleet reporting services
• Enforce multi-tenant architecture using Spring Boot best practices (tenant isolation, security, data boundaries).
• Integrate with and validate behavior against legacy Java systems where required.
• Optimize backend performance using:
  • Spring Boot caching mechanisms
  • Database indexing strategies
  • Read models and query optimization
• Ensure strong consistency of business rules across all backend services.
