The Position
OPSWAT is now searching for a Software Engineering Intern to join our MDCloud product. MDCloud is a real-time malware scanning platform handling 30M+ requests/day, built on a Node.js/TypeScript microservices architecture with event streaming (Kafka, RabbitMQ) and React frontend.
As an Intern, you'll work directly with senior engineers shipping real features, fixing real bugs, and learning how a production-grade cybersecurity platform is built and operated.
What You Will Be Doing
- Implement small features and bug fixes across backend services (Node.js/TypeScript) under guidance from senior engineers
- Write unit and integration tests to improve coverage on existing modules
- 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
