Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, Information Systems, or a related field, or equivalent practical experience.
• 6+ years of professional software engineering experience building production applications.
• Experience with modern web application development, relational data, authentication, authorization, and automated testing.
• Experience with source control, pull requests, code reviews, CI/CD, deployment, and production support.
• Demonstrated ability to translate business workflows into clear application behavior and maintainable software.

• Implement audit history for changes to stability data and operational workflow information.
• Support CSV exports for portfolio and program-level data.
• Integrate vendor-report extraction results into a human-review workflow; extracted values must not be saved automatically and AI must not approve or lock scientific results.
• Build automated tests and contribute to requirements traceability, regression testing, release acceptance, and production readiness with the QA Engineer.
