In many ways, having the engineering/business combination makes a lot of sense. Employment wise as it gives you flexibility to work in different aspects of either field.
Many engineers have great ideas and functional knowledge but have little experience on how to evaluate their worth, market or sell their ideas from a business perspective.
People on the business side (purchasing, sales, marketing) usually have low level engineering knowledge and thus may not fully recognize potential or actual functionality of products and/or services from an engineering perspective.
In my personal experience, engineers with business credentials and experience are a valuable asset to an organization, exceeding the value of either by themselves.
It sounds like you're on that track now, Good luck
