The opening

We are seeking a highly motivated junior (e.g., postdoctoral) researcher to develop and implement an automated, transparent framework for testing, validating, and documenting the lavaan package.

As part of Work Package 2 (Modernize lavaan’s accountability infrastructure) of the ”](https://zenodo.org/records/19552780) project, you will become a member of the lavaan core team to implement modern software best practices into the core package. This will involve collaborating with other core team members and writing comprehensive unit tests to automatically validate user-facing visible outputs as well as invisible underlying background calculations. You will also design a validation testing database to cross-verify lavaan's estimation outcomes against those of alternative commercial and open-source statistical software. Additionally, you will exhaustively document existing and new features, and build an accessible, public-facing documentation website.
