Join us in our quest!

Mercy BioAnalytics is on a mission to improve and save the lives of people across the globe through the early detection of cancer, when it is most curable.

We’ve developed a process which uses nano-particles that are extraordinarily abundant in blood and carry information about their parent cell – known as extracellular vesicles, or EVs – to detect stage I cancer. We are seeking dedicated and passionate individuals to join us in realizing this vision.

Associate Scientist (Bioconjugation)

You will optimize and execute our bioconjugation pipeline for reagents being used in the Mercy Halo assay, and assist with antibody qualification efforts.

Position Details

Who are we?

Mercy BioAnalytics is a diagnostics company dedicated to discovering, developing, and commercializing liquid-biopsy assays to detect cancer at its earliest stages. We employ a novel approach for the early detection of cancer using readouts from individual extracellular vesicles. Our first assay, the Mercy Halo Ovarian Cancer, is in development and seeks to become the first recommended screening blood test for ovarian cancer. In the coming two years, we will begin parallel efforts to develop a blood test for lung and other cancers. We have raised substantial funding toward this end and have moved into a brand-new, 2000-square-foot laboratory located at ABI LABS in Natick, MA. We are looking to expand our team with motivated and skilled scientists passionate about the early detection of cancer.

What’s in it for you?

In this role, you will work collaboratively with a small but highly motivated team of scientists to develop tests for early, non-invasive cancer diagnosis. Mercy BioAnalytics offers a truly exceptional work environment built on teamwork, mutual respect, and a mission-driven passion to save lives and minimize suffering by developing assays to detect cancer early, when it is most easily cured. Mercy offers a competitive pay and employee stock option plan, a medical benefits package including 100% paid health, vision, and dental care, flexible paid time off and sick time, a 401K plan, plus other lifestyle benefits.

What will you be doing?

As an Associate Scientist at Mercy Bio, you will be part of the R&D team that will develop assays against multiple cancer types. Your responsibilities will include:

  • Implementing our bioconjugation workflow for critical assay reagents which will be used across the entire suite of Mercy Halo assays
  • Developing methods to characterize, qualify, and purify bioconjugates using benchtop and/or automated approaches
  • Validating the performance of conjugated reagents in the Mercy Halo assay
  • Preparing written reports and presenting results to a multidisciplinary team

Additionally, you will have the opportunity to improve upon our existing bioconjugation protocols and contribute to the development of next-generation assays.

Throughout this process, our team members are expected and encouraged to contribute intellectually to assay development – brainstorming meetings are frequently held, and all team members are encouraged to participate. By leveraging the perspectives and brilliance of every member or our team, we not only improve our technology but feel that this creates a stimulating and rewarding environment for everyone.

What are we looking for?

The successful candidate will have completed a BS or MS in Biology, Biological Engineering, Chemistry, Chemical Engineering, or similar program, with at least three years of bioconjugation experience. The candidate is expected to be fluent in standard bioconjugation chemistries and have extensive experience with both solid-phase and solution-phase reactions. Additionally, the candidate is expected to be proficient in antibody purification techniques, bioanalytical techniques (e.g., UV/Vis, BCA), PCR, immunoassays (e.g., WB, ELISA), and gel electrophoresis. Experience with HPLC is desirable.

How will you grow with us?

In this role, you will have the opportunity to get in on the ground floor of a young, fast-paced biotech company. You will have the opportunity to optimize our bioconjugation pipeline, innovate, and contribute to new intellectual property. You will gain experience in running studies with our academic collaborators and ultimately participate in running large clinical trials. As Mercy Bio grows and our assay becomes adopted, there would be additional opportunities for setting up, developing, and working in a Mercy Bio CLIA laboratory, as well as in the development of additional early cancer diagnosis assays. Given the size of our company, every individual is vitally important, and everyone has the opportunity to guide and shape Mercy BioAnalytics’ future.
