Participate in code reviews: receiving feedback and reviewing peers
Debug issues in local and staging environments using logs and tracing tools
Read and understand event-driven flows (Kafka consumers, RabbitMQ handlers) to contribute to ingestion and processing pipelines
Update and maintain internal documentation, API specs, and runbooks
Join sprint planning, daily standups, and retrospectives as an active team member
Experiment with frontend components in the internal tooling dashboard (React + TypeScript)
What You'll Learn
By the end of your time on MDCloud, you'll have hands-on exposure to:
Production TypeScript microservices: structure, patterns, and testing
Event-driven architecture with Kafka and RabbitMQ
Docker and basic Kubernetes concepts (deployment, logs, exec)
Code review culture and engineering standards in a global product company
How a cybersecurity SaaS platform processes millions of file scan requests
