Scientist, Stem Cell and Embryology

Experience level: Masters 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 youll 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 workflows across stem cell differentiation follicle isolation and culture IVM gamete and embryo handling embryo culture embryo biopsy ovarian tissue handling 3D culture organoid culture and downstream readouts

• Troubleshoot protocols improve reproducibility and help maintain consistency across difficult and delicate workflows

• Collaborate closely with stem cell reproductive biology embryology genomics and preclinical teams

• Execute technically demanding workflows with precision timing repetition and consistency

What were looking for

• Masters degree PhD or equivalent work experience in stem cell biology developmental biology reproductive biology cell biology embryology bioengineering or a related field

• Ideally 3 years of hands-on experience with human pluripotent stem cell culture reproductive biology embryology follicle culture IVF-adjacent procedures or related technical workflows

• Direct experience with human ESC derivation ESC line establishment or embryo-derived stem cell workflows is especially valuable

• Strong aseptic technique and experience maintaining sensitive high-value cell lines

• Excellent attention to detail reliability and comfort with difficult repetitive protocols that require precision and consistency

• Hands-on experience with hESC/iPSC expansion and banking stem cell QC follicle isolation follicle culture IVM gamete handling embryo handling embryo culture embryo biopsy ovarian tissue handling ovarian cortex cryopreservation 3D culture organoid culture co-culture systems microdissection micromanipulation or long-duration tissue and cell culture workflows is highly desirable

• Strong work ethic and team-first mindset. Willing to do hands-on work including routine and repetitive tasks and step in wherever needed

• Able to thrive in a high-intensity fast-paced flexible startup environment

Why join us

• Impact: Help build the technical foundation for one of the most ambitious programs in reproductive biology

• Ownership: Take responsibility for difficult high-value workflows and help make them reproducible and scalable

• Growth: Develop deep expertise in rare and technically demanding reproductive and stem cell biology methods

• Community: Work alongside passionate scientists tackling one of the most exciting frontiers in biology with a deeply aligned team

• Mission: Build the biological foundation for a new era of reproductive medicine expanding what is possible for millions of people and families with limited options today
