Full Time | $65,000 / year | Company Size: 1-10 employees

Vitra Labs is a venture-backed cell therapy company focused on developing methods to mature human oocytes ex vivo. Our hybrid computational / cell engineering platform allows us to reconstruct the developmental trajectory of oocytes in silico and screen maturation cues in vitro. This technology has the potential to eliminate hormone stimulation prior to oocyte retrieval and produce high-quality, mature oocytes that are ready for IVF; offering unprecedented possibilities to couples struggling with infertility and increasing access to fertility care. Apply to join a collaborative and mission-driven team conducting cutting-edge research to advance women’s health. We offer opportunities for skill development, career growth, and competitive compensation and benefits.
