Job Summary

The Bioinformatics Engineer II position is a 2nd stage position for those with a moderate level of experience in the support of computational environments focused on the management, transfer, formatting, and general processing of complex data types associated with genomics and proteomics. Whereas the Bioinformatics Scientist is primarily focused on the outcome of an analysis in terms of the scientific endpoint, the Bioinformatics Engineer is primarily focused on the outcome of an analysis in terms of validity, efficiency, and robustness. The focus of the position is implementation of data manipulation and analysis pipelines, applications, general hardware configurations, and bioinformatics-specific hardware configurations. The Bioinformatics Engineer II operates in a mostly local computing environment but may also is also represent the needs of large-scale bioinformatics in strategic discussions where those local environments are mapped to enterprise solutions. The position allows for a wide variety of activities described within the job responsibilities and encompasses positions within both research and clinical environments. Activities occur with a moderate degree of supervision with moderate latitude for independent judgment. The Bioinformatics Engineer II will have some experience in best practices as a bioinformatics engineer resource. The Bioinformatics Engineer II is primarily focused on supporting bioinformatics analytical groups and individuals as an engineering domain resource and operational data resource.


The Bioinformatics Engineer II must be able to perform all responsibilities listed in the Bioinformatics Engineer I job description. All responsibilities listed in this description are additional.
