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
