- Collaborate with product, mobile (iOS/Android), operations, data and DevOps teams to drive integration across the stack.
- Optimise performance, scalability and reliability of backend systems under high load (peak retail/ordering traffic).
- Define and enforce best practices for backend service development (code quality, CI/CD, testing, logging/observability, monitoring).
- Contribute to system architecture discussions, trade-offs, and design decisions (including service decomposition, data modelling, event-driven patterns, caching, message queues).
- Mentor junior engineers, provide code review and contribute to team growth and process improvement.
- Help support operational incidents, root-cause analysis and maintain service health in production.
Required Qualifications & Experience

- Proven experience building and operating microservices architectures (services, APIs, message queues, event-driven systems).
- Strong knowledge of RESTful APIs, gRPC, service-to-service communication, data stores (SQL/NoSQL), caching, message brokers (Kafka, RabbitMQ or similar).
- Experience with containerisation (Docker), orchestration (Kubernetes), cloud-native deployments (AWS, GCP or Azure) and infrastructure as code.
- Experience with monitoring, logging, alerting and observability (Prometheus, Grafana, ELK, etc.).
- Strong understanding of distributed systems design, scalable architecture, fault-tolerance and high-availability.
- Experience in performance tuning, profiling and optimisation of backend services.
- Excellent problem-solving skills, ability to work in fast-moving, ambiguous environments (reflecting ZUS's growth phase).
- Good communication skills, ability to collaborate with cross-functional teams and mentor more junior engineers.
- Comfortable working in an agile environment, with CI/CD pipelines, automated testing and iterative delivery.
Desired Skills
- Experience in the F&B, retail or consumer-tech industry (nice to have).
- Familiarity with event-driven and streaming architecture (Kafka, Kinesis).
- Experience with data-warehouse / analytics platform integration or real-time data pipelines.
- Experience in building mobile backend services (for mobile apps) or loyalty/CRM systems.
