If you can’t boil your work down into accessible presentations and adapt them for technical or non-technical audiences, you won’t get anywhere.
Nobody will agree to help you, allow your team to grow, give you budget for tools you need, make compromises with you around integration requirements or shared design patterns, unless you can frequently convert your software work into highly professional presentations.
I’d argue that competent presenting and writing skills are of equal, or even greater, importance than software skills or expert knowledge, whether for a research software job, software contractor job, SWE within tech / ecommerce / banking etc industries - across the board there are pretty much zero types of software engineering jobs in which software skills are actually the most important thing. Presenting and writing are frequently much more important.
