• Evaluate how Docker containers and different system configurations impact application performance, stability, and behavior
• Test interactions between the frontend (React + CesiumJS), backend (Node.js), database (PostgreSQL), and the Windows/Apache environment
• Design and implement practical testing processes and documentation to raise the team’s quality standards
• Conduct system-level evaluation and performance testing of 3D geospatial web applications
• Collaborate with the team to improve code quality, user experience, and overall reliability

• Strong background in software testing, QA, and systems evaluation
• Experience testing containerized applications (Docker) and understanding container-to-system interactions
• CompTIA Security+ (SY0-601 or SY0-701) certification – required
• Experience with PostgreSQL and Node.js

Desired Qualifications:

• Familiarity with agile development principles and practices (SAFe, JIRA)
