Does my work in industry carry any weight in academia?
Weight in academia is carried mostly by peer-reviewed research publications, published in academically reputable venues such as research journals, conferences, books with reputable publishers, reputable preprint servers, ... If you get these publications from industry research, you get academic weight. A famous example for prominent research in electrical engineering done in industry are the Bell laboratories.

Codes and operational manuals are not academic publications, and typically carry little weight. In order to get that, you have to publish academic papers about the codes and manuals, or publish papers about research results obtained with them.
