(Senior) Scientist, Stem Cell

About the role

We are seeking an extremely hard-working, highly skilled, hands-on scientist or scientific specialist to support our pluripotent stem cell program. This is a technical specialist role for someone who wants to be in the lab doing difficult, delicate, high-impact work.

Responsibilities

• Build, optimize, and repeatedly execute workflows needed for stem-cell-derived reproductive cell development
• Derive, establish, expand, bank, and characterize iPSC & ESC lines
• Maintain high-quality ESC/iPSC cultures, document passage history and culture conditions, and support characterization and QC assays
• Troubleshoot protocols, improve reproducibility, and help maintain consistency across difficult and delicate workflows
• Establish epigenetic quality readouts
• Collaborate closely with stem cell, reproductive biology, embryology, genomics, and preclinical teams
• Execute technically demanding workflows with precision, timing, repetition, and consistency

Requirements

• PhD in stem cell biology, developmental biology, reproductive biology, cell biology, embryology, bioengineering, or a related field
• Ideally 4+ years of hands-on experience with human pluripotent stem cell culture, reproductive biology, or related technical workflows
• Direct experience with ESC/iPSC derivation, or ESC/iPSC line establishment 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 ESC/iPSC expansion and banking, stem cell QC, 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

Qualifications

Experience level: PhD plus postdoctoral training or equivalent industry experience (typically 4+ years post-PhD for senior level).

Skills

• Technical skills in human pluripotent stem cell culture, reproductive biology, and related fields
• Experience with troubleshooting and improving technical workflows
• Ability to work independently and collaboratively in a dynamic team environment

Benefits

• Competitive pay
• Company equity
• Excellent healthcare benefits
• Collaborative research environment focused on meaningful results

Pay

Salary is negotiable based on experience and ranges from $80,000 to $150,000 per year.
