What You’ll Own

Backend Engineering

• Design, build, and maintain backend services using Java 20+ and Spring Boot
• Develop clean, secure, versioned REST APIs for web, mobile, admin, partner, and AI systems
• Review and improve Spring Boot application structure, dependency versions, embedded Tomcat configuration, startup behaviour, memory usage, and runtime performance
• Improve service structure, startup behaviour, configuration, and deployment readiness
• Refactor weak or unstable backend areas without breaking existing functionality
• Review and improve backend code quality, error handling, validation, and performance
  
  

Platform Stability

• Investigate production issues across services, APIs, databases, queues, and cloud infrastructure
• Investigate Spring/Tomcat-level issues such as slow startup, failed bean initialisation, blocked request threads, timeout misconfiguration, memory pressure, and unhealthy application states
• Improve application startup, service health checks, logging, retries, timeout handling, and failure recovery
• Identify unstable services, duplicated logic, poor configurations, and risky dependencies
• Create clear root-cause analysis for recurring backend failures
• Help define backend release standards and deployment readiness checks
  
  

Data, Search & Matching

• Work with MongoDB, PostgreSQL/MySQL, Redis, and Elasticsearch
• Optimise queries, indexes, schema design, and data access patterns
• Support course matching, profile enrichment, search, recommendation, and application workflows
• Improve backend data consistency between APIs, databases, search indexes, and AI outputs
  
  

Cloud & Infrastructure

• Work confidently with AWS-backed backend environments, including services such as EKS/ECS, EC2, Lambda, RDS, S3, IAM, CloudWatch, and SQS/SNS, in collaboration with DevOps/Cloud engineers
• Support containerised deployments using Docker and Kubernetes
• Review backend infrastructure for cost, security, reliability, and scalability
• Help reduce unnecessary cloud costs caused by inefficient services, oversized resources, or poor runtime behaviour
• Partner with DevOps/Cloud engineers to improve deployment pipelines and runtime environments
  
  

Messaging & Integrations

• Work with Kafka, RabbitMQ, or AWS SQS/SNS
• Audit existing message/event flows and identify what is used, unused, broken, or risky
• Build reliable asynchronous workflows for notifications, AI processing, applications, search updates, and partner integrations
• Integrate third-party services such as payment gateways, email/SMS providers, CRMs, AI/ML APIs, and institution partner systems
  
  

Security & Access

• Build secure backend services using Spring Security, OAuth2, JWT, SSO, and role-based access control
• Work with identity systems such as Keycloak or similar
• Improve API security, permission checks, secrets management, and environment variable hygiene
• Identify risky public endpoints, exposed credentials, weak service-to-service access, and insecure configurations
• Apply secure coding practices across backend services
  
  

Observability & Monitoring

• Improve backend logging, metrics, alerts, tracing, and health dashboards
• Work with tools such as CloudWatch, ELK, Grafana, Prometheus, New Relic, Datadog, Rollbar, or similar
• Make it easier to detect user-impacting failures such as login issues, API failures, slow responses, and broken workflows
• Help define what “healthy backend” means for Yuzee
  
  

Leadership & Mentoring

• Review pull requests and raise engineering quality across the team
• Mentor junior and mid-level developers while maintaining delivery momentum
• Break large technical problems into clear, shippable milestones
