11d•Onsite

About The Position

Colossal is seeking a researcher to lead groundbreaking research on oocyte collection and embryo transfer techniques in non-model organisms, as well as the in vitro production of gene-edited embryos. The role works with reproductive biologists to develop, implement, and maintain strategic plans for the embryology department and reports to the Director of Assisted Reproduction. The position is based in Dallas, Texas, and relocation assistance is provided. The scientist will develop and optimize assisted reproductive protocols across novel and model species, collaborate on oocyte and embryo transport conditions, conduct experiments informed by relevant literature, and troubleshoot protocols to maintain successful outcomes. The role includes travel to train others and implement assisted reproductive technologies in non-model organisms, potentially up to 25% of the time. Colossal describes its team as collaborative and distributed across laboratories, test facilities, academic institutions, libraries, and offices. The company states that it is an equal employment opportunity workplace committed to diversity and an inclusive environment free from discrimination and harassment.

Requirements

Strong expertise in comparative reproductive biology, including endocrinology, oocyte maturation, and pre-implantation embryo development.
Experience with transrectal palpation and ultrasound to monitor ovarian activity and early pregnancy.
Experience with transvaginal and/or laparoscopic oocyte collections.
Experience with gamete and embryo cryopreservation.
Strong written and verbal communication skills.
Ability to work independently and collaboratively with Animal Operations and Embryology teams, including veterinarians, scientists, and animal husbandry experts.
At least three years of experience with oocyte collection, embryo collection or production, and embryo transfer, with a track record of successful pregnancies.

Experience with multiple species, including non-traditional (wildlife) models.

Responsibilities

Develop protocols for transvaginal, transrectal, or laparoscopic oocyte collection in a variety of novel and model species.
Optimize estrus synchronization and superovulation protocols for species that are difficult to handle frequently.
Collaborate with the embryology team to optimize oocyte and embryo transport between animal facilities and Colossal headquarters laboratories.
Stay current with relevant literature, identify potentially applicable novel protocols and procedures, and conduct experiments to improve results.
Maintain stable success rates and troubleshoot protocols as needed.
Travel to train others and implement novel assisted reproductive technologies in non-model organisms.
