Senior Principal Associate Scientist, Biology/Immuno-Oncology

Biology Cambridge, Massachusetts


What’s in it for you?

You will conduct laboratory research and contribute both to discovery pipeline programs and mechanistic studies with Mersana’s proprietary Immunosynthen platform. You’ll generate experimental data that directly informs key decisions for project teams, and you will participate in the decision-making by sharing your expertise and perspective. You’ll continue to develop your technical skills by mastering new techniques, by learning about the work of colleagues in chemistry, bioconjugation, and pharmacology, and by attending symposia and conferences. You’ll have the opportunity to become the “go-to” subject matter expert in various aspects of our work. You will also be exposed to strategies, discussions and decisions regarding our clinical programs during regular meetings that constitute a cornerstone of our culture. You will immerse yourself in one of the hottest therapeutic modalities in oncology: antibody-drug conjugates (ADCs).

How do you know if you’re the right fit?

You love doing experiments. You’re interested in all aspects of an experiment – hypothesis generation, experimental design, the labwork, data interpretation, and troubleshooting. You like trying new instruments and developing new assays; you like asking advice of your colleagues when troubleshooting. You are motivated by the desire to impact patients’ lives through drug discovery and you appreciate the teamwork that is critical for success.
