As someone who worked on a bookkeeping system without being an accountant (or bookkeeper in any sense), I'd say your challenge is that it's very possible to learn enough to build a decent system, assuming your engineering knowledge is strong.

I don't say this to blow my own trumpet, only to say that the non-engineering leadership at the company in question were very invested in the product details and making sure I understood basic accounting principles.

That said, I went from that role to working in a billing system that was originally built by a team where leadership weren't invested in the details. The result was a lot of issues and frustration from Finance leadership. Storing monetary values in float was not the biggest issue, either.

That being said, maybe branch out of just looking at accounting/bookkeeping and market yourself as "I know how money works in software systems." Your skills are extremely transferrable and knowing the Finance expectations will make it easier to make good design choices further upstream.
