Alternative title for research assistant I’m taking a (non-student) job as a full time research assistant in a university engineering department, and am wondering what alternate title I could use for this on my resume that isn’t misleading.

Research assistant has a connotation of being a lower level student job, and I have a MS degree and ten years of work experience, so I’m hesitant to put that title on my resume.  If this was in industry I could use research engineer, but in academia, that has a connotation of someone who is a principle investigator and has a PhD. 

My job description is a hybrid between these: I’ll be doing research and publishing, but in support of someone else’s project.  Also some departmental work setting up labs, learning and maintaining the equipment and helping teach students to use it.  Most of my time will be spent on research activities.  Suggestions for an alternate job title?
Since you are in the US, I think "Research Assistant" is actually not as inappropriate a title for your position as you suggest. See for example https://en.wikipedia.org/wiki/Research_assistant

"Research Assistant" is typically the job title a PhD student would hold if they are compensated for work on a professor's research, whether or not they have a masters degree. It is differentiated from "Research Associate" which suggests the person has a PhD ('postdocs' often have a job title of Research Associate, though they may also be referred to as Postdoctoral Research Assistants). Your years of experience on the outside aren't particularly relevant to the title.

You write:


  I’ll be doing research and publishing, but in support of someone else’s project


That's roughly the job description of a graduate student with a research assistantship.

Undergraduates may also have a "research assistant" title but in my experience that is not the most common use/connotation of the term, so I disagree with that statement at least within academia. People outside of academia may be misinformed, of course, but it's up to the rest of your resume to inform potential employers of your responsibilities and accomplishments besides your particular job title. You could be an independent consultant and name yourself CEO if you wanted, or Grand Emperor for that matter. It may be harder to change your official job title in a rigid university bureaucracy than you think - I'd concern yourself with other aspects of your resume instead.
