The ultimate Tech Stack Cheat Sheet for Recruiters

Let’s face it—recruiters aren’t expected to be developers, but if you’re hiring for technical roles, you need to speak their language. A solid understanding of tech stacks not only helps you screen candidates better but also earns you credibility with hiring managers and engineers.

Here’s your no-fluff, quick-reference guide to programming languages, frameworks, and tools. Save it, bookmark it, and use it every day!

Programming Languages: The building blocks

• JavaScript: The backbone of web development, used for interactive websites and front-end frameworks like React and Angular.
• Python: The Swiss Army knife of programming—great for web development, data science, machine learning, and automation.
• Java: A go-to language for large-scale enterprise applications, Android development, and backend systems.
• C#: Used primarily in Windows applications, game development (hello, Unity), and enterprise software.
• Ruby: Known for simplicity and speed, often used with Ruby on Rails for web development.
• Go (Golang): Popular for microservices and highly scalable systems.
• Rust: Rising in popularity for system-level programming and high-performance applications.

Frameworks: Accelerators for development

• React.js: A front-end library for building user interfaces (popular in startups and enterprises alike).
• Angular: Google-backed framework for building robust, dynamic web applications.
• Vue.js: A lightweight alternative to Angular and React, ideal for startups.
• Django (Python): Framework for building secure and scalable web applications quickly.
• Spring (Java): Common in enterprise backend development, especially for APIs and web services.
• Express.js (Node.js): For building fast and scalable server-side applications.
• ASP.NET Core: Microsoft’s framework for building cloud-based, modern web applications.

Databases: Where the data lives

• SQL (Structured Query Language): Used with relational databases like MySQL, PostgreSQL, and SQL Server. Essential for structured data storage and analysis.
• NoSQL: Includes MongoDB, Cassandra, and Redis. Great for unstructured data and real-time applications.
• Firebase: Google’s cloud-based NoSQL database for web and mobile applications.

DevOps & Cloud Tools: The backbone of modern tech

• Docker: For containerization—think of it as packaging up applications so they can run anywhere.
• Kubernetes: Manages and scales containers in production.
• AWS (Amazon Web Services): The industry leader in cloud services.
• Azure: Microsoft’s cloud platform, popular in enterprises.
• Git/GitHub/GitLab: Tools for version control and collaboration.
• Jenkins: A tool for continuous integration and delivery (CI/CD).

AI & Data Science tools: The future is now

• TensorFlow & PyTorch: Frameworks for building machine learning models.
• Tableau: A data visualization tool used for analytics.
• Spark: For big data processing.
• Hadoop: Manages and processes massive datasets.

Cybersecurity tools: keeping it safe

• Wireshark: A network analysis tool to detect issues and threats.
• Splunk: Monitors and analyzes machine-generated data for cybersecurity insights.
• Metasploit: A penetration testing framework.
• Nmap: A tool for network scanning and security audits.
• OWASP ZAP: Open-source tool for finding security vulnerabilities.

Quick Glossary: What to know when hiring for roles

• Frontend Developers: Work on what users see (HTML, CSS, JavaScript frameworks like React, Angular).
• Backend Developers: Build what happens behind the scenes (Java, Python, Go, databases).
• Full Stack Developers: Combine frontend and backend skills.
• Data Engineers: Manage data pipelines and storage (SQL, NoSQL, Spark).
• DevOps Engineers: Bridge the gap between development and operations (AWS, Docker, Kubernetes).
• Machine Learning Engineers: Develop AI models (Python, TensorFlow, PyTorch).
• Cybersecurity Analysts: Protect systems and data from threats (Splunk, Nmap).
