Job description

Senior Backend Go (Golang) Software Engineer

Key Responsibilities

Design, develop, test and maintain backend services and APIs using Go (Golang) in a microservices architecture. Build scalable and reliable services to support ZUS Coffee's digital ordering, mobile app, loyalty/rewards system, store-operations backend and delivery-logistics. Participate in all phases of software development: requirements analysis, design, implementation, deployment, monitoring, and continuous improvement. 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

Bachelor's or Master's degree in Computer Science, Software Engineering or related field (or equivalent practical experience).

Strong experience in Go (Golang)

: typically 4-7 + years software engineering experience in backend development, with at least 2-3 years chiefly in Go. 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. Knowledge of Go frameworks (e.g., Gin, Echo), or contributing to open-source Go libraries. Understanding of cloud serverless technologies. Familiarity with security, authentication/authorisation (OAuth, JWT), API gateway design.
