• Champion best practices in testing, documentation, and technical debt management

• Serve as the primary software architect for multiple in-house, multidisciplinary engineering analysis tools

• Refactor and optimize scientific codes for maintainability, scalability, and performance.

• Implement object-oriented software designs, modular architectures, and version control (e.g., Git).

• Develop interfaces and workflows for multiphysics simulations (e.g., MOOSE-based applications).

• Create and execute verification and validation (V&V) plans for physics-based codes, including unit and regression tests and benchmark comparisons

• Establish traceability between requirements, test cases, and validation datasets.

• Document assumptions, limitations, and validation results for stakeholder review.

• Prepare codes for formal release by acting as the primary release manager

• Develop continuous integration / continuous development (CI/CD) pipelines for automated builds and testing.

• Ensure reproducibility and auditability of all software artifacts.

• Collaborate with AMA and NASA staff engineers and scientists to translate complex physics models into robust computational implementations.

• Communicate with a multidisciplinary team of engineers and project managers via presentations and technical report writing.
