Full Job Description
Experience level: Master’s, PhD, or equivalent work experience. About Conception Conception is pioneering the future of reproductive biology by generating functional human eggs from induced pluripotent stem cells (iPSCs). Our mission is to unlock new possibilities for fertility, reproductive health, and genetic diversity. We are building a world-class team at the intersection of stem cell biology, developmental biology, and reproductive biology to make this vision a reality. The position We are seeking an extremely hard-working, highly skilled, hands-on scientist or scientific specialist to support our in vitro gametogenesis program. This is a technical specialist role for someone who wants to be in the lab doing difficult, delicate, high-impact work. The most critical skillset is human ESC line generation and expert pluripotent stem cell culture. Ideally, you have direct experience deriving, establishing, expanding, banking, and characterizing human ESC lines. Experience with follicle culture, gamete handling, embryo handling, embryo biopsy, IVM, ovarian tissue workflows, 3D culture, stem cell differentiation, or related reproductive biology techniques is highly valuable. This is not a traditional clinical embryologist role and not a management role. We are looking for a rigorous bench scientist who is excited to execute, troubleshoot, repeat, improve, and master technically demanding workflows. The right person will be flexible in focus, willing to learn new techniques, and motivated to contribute wherever the lab needs them most. Title is negotiable based on experience and may range from Scientific Specialist to Scientist. What you’ll do - Help build, optimize, and repeatedly execute workflows needed for stem-cell-derived reproductive cell development - Derive, establish, expand, bank, and characterize human ESC lines - Maintain high-quality hESC/iPSC cultures, document passage history and culture conditions, and support characterization and QC assays - Support w
