CI/CD & Build Tools

Continuous Integration and Continuous Deployment (CI/CD) tools automate software building, testing, and deployment pipelines, forming the backbone of modern DevOps practices. Jenkins dominates the CI/CD landscape with >60% prevalence in Build & Release Management and >25% in DevOps positions, despite being a legacy tool. Modern cloud-native alternatives like GitHub Actions and GitLab CI are rapidly growing, appearing in >10% of DevOps and platform roles. Azure DevOps serves Microsoft-centric organizations. Build tools show language-specific specialization: Maven and Gradle dominate Java ecosystems (>30% and >15% in Build & Release Management respectively), while npm and Webpack serve JavaScript, and Make/CMake support C/C++ compilation. Entry-level accessibility is strongest for Jenkins (>50% in entry-level build/release roles), GitHub Actions, and Maven, reflecting their widespread adoption. The landscape is shifting toward integrated git-based CI/CD platforms (GitHub Actions, GitLab CI) from standalone servers, while build tool expertise remains essential for language-specific development workflows across backend, mobile, and systems engineering.

CI/CD Platforms

Continuous integration and deployment platforms automating build, test, and release workflows. Jenkins leads with massive adoption despite legacy architecture, while GitHub Actions and GitLab CI represent modern git-integrated approaches. Azure DevOps serves enterprise Microsoft environments. Strong entry-level opportunities, particularly for Jenkins and emerging platforms.
