ROLE
We are seeking a Senior Biologist to provide highly specialized scientific and technical support to a National Institutes of Health (NIH) research laboratory within the Epithelial Signaling and Transport Section in Bethesda, MD. The work focuses on epithelial biology, calcium signaling, endoplasmic reticulum–plasma membrane (ER–PM) junction organization, and ion channel regulation, with direct application to ongoing and planned NIH intramural research projects.

This is a senior, part-time, hands-on role that requires immediate proficiency in advanced imaging, molecular biology, and quantitative analysis. The selected candidate will work independently, provide mechanistic insight to complex biological questions, and integrate into an established NIH research environment. This role requires an experienced scientist who can perform the required techniques from day one, with no ramp-up period.

Apply today!

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
