Senior Medical Science Liaison Remote - USA Quanterix is a global leader in ultra-sensitive biomarker detection, enabling breakthroughs in disease research, diagnostics, and drug development. Its proprietary Simoa technology delivers industry-leading sensitivity, allowing researchers to detect and quantify biomarkers in blood and other fluids at concentrations far below traditional limits. With more than 3,400 peer-reviewed publications, Quanterix has been a trusted partner to the scientific community for nearly two decades. In 2025, Quanterix acquired Akoya Biosciences, The Spatial Biology Company, adding multiplexed tissue imaging with single-cell resolution to its portfolio. Together, the combined company offers a uniquely integrated platform that connects biology across blood and tissue-advancing precision medicine from discovery to diagnostics. ROLE SUMMARY: Lucent Diagnostics, a Quanterix brand, is pioneering ultra-sensitive, blood-based biomarker testing for Alzheimer's disease. Using Simoa Technology, we empower providers with earlier, more accurate detection, enabling better patient outcomes. We are committed to transforming Alzheimer's detection and diagnosis through cutting edge biomarker testing. Our goal is to make highly sensitive, accessible blood tests the new standard of care, reducing reliance on invasive procedures. is seeking an experienced and highly motivated Senior MSL to join our Commercial team. This is a remote, field-facing role with primary responsibility for Medical Science Liaison (MSL) activities, with a focus on neurodegenerative disease and diagnostic biomarker testing. In addition to leading external scientific engagement, this individual will contribute to cross-functional initiatives, including market access and evidence strategy, as needed. This role is ideal for a senior MSL who thrives in a player-coach environment and wants to shape medical affairs strategy while remaining close to clinicians, data, and real-world implementation.
