I am a co-author on a research paper published in a scientific venue. The coworker who is lead author had the original idea and did most of the implementation work. I've only been of accessory help and my bigger contributions to that idea came later, as improvements, and were not published.
Since I am applying to research or research-adjacent jobs (without a PhD), I want to add this paper to my CV. But I don't want interviewers to believe I have more research experience than I have and feel misled when I correct them.
How should I present this paper? Just as an academic citation with title, authors, and venue, or add a note saying which role I had in that project?
