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
  • Write technical documentation that explains systems, decisions, risks, and fixes
  • Push back on poor technical decisions with evidence and better alternatives
