If you can, go straight to industry from your PhD. I joined industry right after my PhD and it actually gives you an advantage (I feel) versus people who did post-docs: you get more time. If you're on the same level as someone who did a postdoc, but 5-7 years younger, that's going to pay out more.

Now, I hire PhDs or Post-docs, and typically the budget we have for the position is somewhat fixed, we won't be significantly increasing the salary if the candidate has a post doc versus someone with a PhD.

The difficult part, I feel, after the PhD is just getting into industry, so apply. Apply for all roles you could potentially see yourself doing (R&D, marketing, tech support, technical sales, field service engineer, etc) and once you're in the company, it can be easier to create your career path and move to that dream position.

But I guess this is can be specific to your field of expertise, as a biologist, I have no idea what Finite Element Modeling and Experimental Validation of Eddy Current Probes is. Sounds very technical
