Responsibilities:

• Extend, and maintain patch and software definitions across supported OS platforms and third-party applications
• Java and Kotlin backend development to expose patch management platform functions for extensibility
• Build and maintain React-based UI components for the patching workflows and dashboards customers rely on

• Participate in architecture and design reviews to build high-quality, scalable, API-first software that can reliably patch endpoints at scale

• Bachelor's degree in Computer Science, Computer Engineering, Information Technology, or equivalent work experience
• 10+ years of experience in Java software development for product applications, or equivalent, with solid expertise in Kotlin

• Experience leveraging AI tooling to accelerate software development
• Working knowledge of a breadth of OOP design principles; expertise in scaling data structures and object-oriented design
• Knowledge of API best practices and REST service development using frameworks like Jersey or Spring

• Caching systems expertise
• Expert knowledge of quality testing practices, including front-end testing frameworks
