Software Engineering Intern

OPSWAT , a global leader in IT, OT , and ICS critical infrastructure cybersecurity, delivers an end-to-end platform that gives public and private sector organizations and enterprises the critical advantage needed to protect their complex networks, secure their devices, and ensure compliance. Over the last 20 years our commitment to innovative technology has earned the trust of more than 1,700 organizations, governments, and institutions globally, solidifying our role in protecting the world’s critical infrastructure and securing our way of life.  
The Position
OPSWAT is now searching for a Software Engineering Intern to join our MDaaS product. MDaaS 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 — both 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 MDaaS, 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


 
What We Need From You
Education & Background


•
Pursuing or completed a degree in Computer Science, Software Engineering, or equivalent


•
Able to commit at least 4 months (internship) or full-time (associate)


Soft Skills

•
Communicates clearly in English (written); able to describe problems and solutions concisely


•
Receptive to feedback and willing to iterate quickly


•
Comfortable working in a team across different timezones


Technical Fundamentals


•
Solid understanding of programming fundamentals: data structures , algorithms, OOP


•
Hands-on experience with JavaScript or TypeScript — coursework or personal projects count


•
Familiar with Git : branching, pull requests, resolving conflicts


•
Basic understanding of REST APIs : HTTP methods, status codes, request/response structure


•
Able to read and understand existing code in an unfamiliar codebase


•
Actively uses AI coding tools (GitHub Copilot, Cursor, Claude, ChatGPT) as part of daily workflow — knows how to prompt effectively, verify output, and not blindly trust generated code


Dev Environment


•
Comfortable working in a Linux/macOS terminal


•
Knows how to run a project locally with Docker Compose


•
Can use a debugger or structured logging to trace a bug


 
If Would Be Nice If You Had
 


•
Prior internship or project experience with a Node.js or TypeScript backend


•
Familiar with any testing framework (Jest, Vitest, Mocha)


•
Basic React knowledge — able to build or modify a UI component


•
Exposure to message queues (Kafka, RabbitMQ, Redis) — even conceptually


•
Knows what a microservice is and why services communicate over events


•
Experience with any cloud provider (AWS, GCP, Azure) — even free tier


•
Interest in cybersecurity — malware analysis, threat intelligence, or security tooling


•
Has read about or experimented with CI/CD pipelines


•
Experience building features or scripts with AI assistance end-to-end — from prompt design to testing the result


•
Understands limitations of LLM-generated code: hallucinations, outdated APIs, security blind spots


•
Has experimented with AI APIs (OpenAI, Anthropic, Gemini) in side projects


•
Familiar with concepts like RAG, embeddings, or function calling — even at a basic level
