About The Position

At Countable Labs (formerly Enumerix), we are redefining what modern genomics can be. Our Countable PCR platform delivers highly accurate, multiplexed quantification with the simplicity of qPCR and at a cost that makes advanced genomics broadly accessible. In 2025, Countable PCR was recognized with both Analytical Scientist and Scientist Innovation awards, validating the platform’s scientific impact and real-world value. Backed by top-tier life sciences venture capital firms, we are building a category-defining technology that enables next-level genomics for clinical and research applications. We are a fast-growing, mission-driven startup where ownership is real, innovation is expected, and product leaders have the opportunity to shape the future of an entire platform. If you want to take charge of a portfolio, guide world-class science into the market, and see your decisions translate directly into customer impact, this is the role for you. We are seeking a Senior / Staff Product Manager to own and lead the strategy, development, and lifecycle management of Countable PCR’s reagents and clinical assay portfolio. This role is a true portfolio ownership position. You will define what assays we build, why we build them, and how they come to life. You will drive the Product Development Process, guide R&D priorities, and ensure our assay and reagent ecosystem evolves in step with customer needs, clinical use cases, and platform capabilities. You will operate at the intersection of science, product, and business, partnering deeply with R&D while providing clear direction, structure, and product leadership. The ideal candidate is excited by responsibility, comfortable making decisions, and motivated by building something that has not existed before.
