You are special. There are lots and lots of "software engineers" in the world. Very very few can bring scientific experience and knowledge to the job. I might look for a developer role in a large university project where they need programming skills and scientific rigor. Or a R&D person in a large software company or the government . These kinds of jobs aren't listed on Indeed or Monster. Attend conferences related to your field (don't attend the talks, hang around in the lobby and chat with people). Reach out to professors in your university or your field.

All the Best!
