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

• Curious and proactive — asks questions, doesn't wait to be unblocked

• 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

About the Role

The CTO Intelligence Hub is OPSWAT’s internal AI-powered data platform; dashboards and APIs that give leadership real-time visibility into AI adoption, financial performance, customer health, and sales. The platform runs on a fleet of Flask, FastAPI, and Streamlit applications backed by a Fabric → Parquet → S3 data pipeline, all tied together by an agentic coding system where GitHub Issues become production pull requests in under three minutes.

As AI Platform Architect, you own the application layer. You design and build new intelligence products, evolve existing dashboards, and work with the AI coding pipeline — writing the specs, reviewing the plans, and guiding the implementation. You are the “human senior engineer” in a team where your main coding collaborator is Claude.

What You Will Own

• Application architecture: Flask APIs, FastAPI microservices, Streamlit dashboards; schema and data-flow design across 12+ applications
• Agentic coding pipeline: creating well-scoped GitHub Issues, reviewing AI-generated implementation plans, approving or refining, merging PRs; the pipeline (claude-coder) takes issues from triage to production PR in ~3 minutes for routine work
• Data pipeline & analytics: extending the Fabric → Parquet → S3 pipeline; designing new analytics (percentile ranking, quadrant analysis, trend computation); HR enrichment and data quality
• Test-driven development: writing pytest spec suites that the AI implementer must satisfy; test files are the spec and cannot be modified by the AI
• Claude API / CLI integration: building features that call Claude for inference (content generation, analysis, RFP answering); working with OAuth-based CLI inference and direct API patterns
• UX & visualisation: Plotly dashboards, Jinja2 templates, React/Vite prototypes; maintaining the OPSWAT brand system across all apps
• Architecture documentation: keeping Confluence up to date as the system evolves; writing CLAUDE.md context files that teach the AI pipeline how each repo works
• New product design: identifying gaps in current intelligence coverage and proposing, scoping, and shipping new internal tools

You Will Be a Strong Fit If You Have

• 3–7 years of Python backend development (Flask, FastAPI, or equivalent)
• Strong data skills: pandas, SQL, Parquet, data modelling; you are comfortable designing a metrics pipeline from raw HR and usage data to ranked leader-board
• Experience working with LLM APIs (OpenAI, Anthropic, or equivalent) in production
• A test-first mindset: you write tests before code and believe the test suite is the specification
• Clear written communication because your primary “pairing partner” reads GitHub Issues, your ability to write precise, unambiguous requirements directly determines output quality
• Comfort reading and reviewing AI-generated code critically; you know when to approve, when to push back, and when to take the keyboard yourself
• Experience with REST API design and documentation

Nice to Have

• Streamlit or Plotly dashboard development
• React / TypeScript (for UX prototypes)
• Microsoft Fabric, Azure Data Warehouse, or similar cloud data platforms
• Familiarity with GitHub Actions and CI/CD pipeline design
• Experience building multi-language document processing (the RFP automation covers 14 languages)
• Prompt engineering and system-prompt design for agentic workflows
• OPSWAT product knowledge (MetaDefender, OESIS, CDR - not required but helpful)
