A physicist can be a good multi-disciplinary, quantitative problem solver. I think the reason is that physics doesn't "own" very many practical techniques, so we are constantly borrowing from other fields. Physicists also tend to keep their math skills after graduation. Most program well enough to be dangerous, and with a bit of guidance can become good developers.

I got a BS in math and physics, then continued for a PhD in physics. Today I work for a company that makes measurement equipment. We have engineers from most of the traditional disciplines, but they tend to be silo'd, and happy to avoid math and theory. Unavoidably, understanding (and proving) how the product works involves a combination of mechanical, electronics, data processing, statistics, and so forth. My long term role is to be the person who understands how the product works, not only acquiring domain knowledge but creating it.

The deal is that physics isn't an exclusive guild, and there are people in other disciplines with similar inclinations, but they're as rare as physicists. So I can't tell you why you need a physicist at the exclusion of any quantitative engineer with 30 years of experience. I can't promise that you'll get rich at it. I just try to help people and learn new things.
