The difference, imo, is basically in how you define your primary goal. Is it software development or is it specifically informatics?

In my experience (in academia) most informaticians are focused on the data whereas my focus is software development in support of the informaticians’ goals.

Take a look at some Universities that have Biomedical Informatics departments; I started with a University that has such a department. They’ll typically have faculty that have grant-funded projects that require a software component, whether it’s NLP, AI, ML or application development for various purposes (including clinical-use software).

Also look for organizations or companies working with HL7 standards (most recent tech is FHIR (http://hl7.org/fhir/)).
