Funnily enough, I came to similar conclusions and have been describing myself and some colleagues as Product Engineers for years now!

Software engineering is just a means to delivering product value.

In interviews I now primarily drill down on the company's business model, target customers and wider organisational structures outside of the engineering team. I have found these have the biggest impact on your ability to deliver product value. Everything within the engineering team (technologies, architecture etc.) is well within your realm of influence but you're going to face a massive uphill battle if the core business model is amiss.
