From Spear Bio's posting. “We” and “our” refer to the employer.
Spear Bio, founded in 2021, is a well-funded and rapidly growing biotech start-up headquartered in Woburn, Massachusetts. Our proprietary technology, Successive Proximity Extension Amplification Reaction (SPEAR)
, is a novel wash-free immunoassay platform, offering unprecedented sensitivity. We are dedicated to revolutionizing early disease diagnosis and monitoring by providing scalable, ultrasensitive solutions that deliver unparalleled accuracy in measuring low-abundant biomarkers, enabling clinicians and researchers to improve patient outcomes and advance global health.
Scientist/Senior Scientist, Assay Development -
Molecular Assay Chemistry and Biophysics
Our Assay Development team builds assays for low-abundance protein biomarkers that are challenging to measure using conventional approaches. We are seeking a creative, hands-on scientist with strong fundamentals in chemistry, biophysics, and molecular interactions who enjoys solving difficult technical problems from first principles.
The Scientist / Senior Scientist will design, optimize, and troubleshoot innovative protein-detection assays that integrate antibody-based recognition, nucleic-acid interactions, conjugation chemistry, reaction kinetics, and quantitative analytical methods.
We are looking for a scientist who genuinely enjoys troubleshooting. The ideal candidate is persistent, analytical, creative, and comfortable working through uncertainty. This person should be motivated by understanding the underlying mechanism and should thrive in a fast-moving startup environment with high scientific standards.
The successful candidate will be comfortable investigating why an assay behaves unexpectedly, developing mechanistic hypotheses, designing discriminating experiments, and systematically improving assay sensitivity, specificity, robustness, and reproducibility.
We welcome applications from exceptional recent Ph.D. graduates and postdoctoral fellows with strong hands-on research ownership, as well as startup and industry scientists who have demonstrated rapid growth in technical scope and responsibility. **This role is based onsite in our lab in Woburn, MA 5 days/week.
