Hi Adam,
It doesn't matter what background you belong to, as long as you are willing to learn, you're more than welcomed here!
To continue to strive and find a job in this space, you first need to identify what job description suits you more aptly, check out some here: https://blockgeeks.com/guides/blockchain-jobs/ [note that not all jobs require coding experience, so you can still land a job in this space even if you're not interested in a purely technical role].
After that, explore projects and get involved in discussions, (virtual) meetups, and more to understand the space dynamics and contribute where yo can [you have your own supply chain experience which I am sure has some inconsistencies that blockchain can resolve, think around that line and you might be able to assist projects working in SC specifically]. This will get you noticed by peers and you'll be able to onboard projects and land yourself a good opportunity. It takes persistence and time, just make sure you're always open to learning and unlearning.
