Having worked at various manufacturing companies (telecomms, industrial automation, oil, IoT) over many decades, I'd suggest go work for a company that software is part of a bigger system. There's quite a lot that goes into it. The designing/engineering part is just a part of the overall business. So I'd look at the bigger system/process. There's a number of ideas on how to run a manufacturing process, continuous flow, minimizing stock, contracting out parts, what happens after sales, end of life, etc. Consumer products are very different from industrial / specialist products.
