Do I have to list my current part time spa job on my resume when I am looking for work in biotech/pharma?


I am looking for work in the biotech industry. I work at a spa doing massage on friday nights and saturdays. Do I have to list this on my resume? Is not lisiting this job a material omission? I really dont want to highlight my massage work on my resume but dont want to lie or do anything that could negativeley impact me getting a biotech job.
