You can definitely work at QC companies even without having a degree in the field. Many QC companies hire people from other fields because they require that expertise, say people with experience in numerical optimization. Of course, many QC companies also hire software engineers because they have complex internal software. If you are a software engineer, you can start there and then start to move laterally within the company.
