• Define and enforce architectural principles and patterns, including: Domain-driven design (DDD), Event-driven architecture (Kafka/RabbitMQ or similar), API-first design (Open API standards), Microservices and containerization.
• Architect high-performance, fault-tolerant systems capable of handling large-scale order volumes across multiple channels.
• Design and standardise integration patterns between order systems and external/internal services such as payment providers, Warehouse and logistics systems, Marketplace platforms, and customer and inventory systems.
• Establish data consistency and reliability strategies, including eventual consistency, idempotency, and distributed transaction handling.
• Define observability, monitoring, and alerting strategies to ensure system reliability and performance.
• Collaborate with enterprise and solution architects to ensure alignment with overall platform architecture.
• Provide technical leadership and mentorship to engineering teams, guiding design decisions and best practices.
