We recently shared that we have, for the first time, generated early human egg cells and follicles entirely from stem cells. The next major challenge is to support those fully stem cell-derived follicles through growth and maturation.\nWe are building a world-class scientific team to solve this problem and create new possibilities for fertility and reproductive health.\nThe position\nWe are seeking an exceptionally strong, hands-on senior scientist to help drive the development of advanced 3D tissue and organoid systems.\nThe strongest candidates will have personally built new differentiation, organoid, or complex multicellular culture systems and worked through the biological and technical challenges required to improve their fidelity, maturation, function, and reproducibility.\nDirect reproductive biology experience is not required. We are excited about scientists who have built difficult systems in other tissues and can bring new approaches to ovarian biology.\nIn this role, you will lead the development of advanced stem-cell-derived ovarian tissue systems central to Conception’s mission. You will work across developmental biology, cell-cell interactions, tissue organization, the cellular microenvironment, matrix and mechanics, signaling, metabolism, computation, and culture design to build systems that more faithfully recapitulate human ovarian biology.\nWhat you’ll do\nOwn the scientific strategy and day-to-day development of our ovarian organoid and follicle niche systems\n\nDesign and build new differentiation and tissue engineering approaches that support follicle formation, growth, maturation, and oocyte competence\n\nIdentify the main biological and technical bottlenecks, prioritize the highest-value experiments, and systematically improve the system\n\nEstablish quantitative, stage-specific, and functional readouts that distinguish meaningful biological progress from marker expression alone\n\nRemain deeply hands-on and close to the cultures, experiments, and data\n\nWork closely with cross-functional teams to integrate complementary approaches and advance shared scientific goals\n\nMentor and develop scientists while setting a high bar for rigor, documentation, pace, and scientific thinking\n\nHelp build a team culture grounded in curiosity, urgency, flexibility, technical excellence, and transparency\n\nWhat we will provide\nYou will build from a strong scientific foundation, including advanced stem-cell-derived ovarian tissue systems, extensive internal datasets, and human reference biology. You will work closely with a strong cross-functional team across stem cell biology, developmental biology, reproductive biology, computation, and engineering.\nWe will provide the resources and flexibility to test new approaches, bring in the right tools and collaborators, and build additional expertise around the program as it grows. You will have direct support from scientific and company leadership and meaningful ownership over the direction of the work.\nWhat we’re looking for\nPhD in a relevant field, plus postdoctoral training or equivalent industry experience\n\nStrong track record of personally building or substantially improving complex organoid, tissue, or differentiation systems\n\nDeep understanding of cell-cell interactions and how the microenvironment shapes tissue development and function\n\nExceptional hands-on troubleshooting and experimental judgment\n\nAbility to set scientific direction, prioritize clearly, and turn complex data into actionable next steps\n\nClear communicator who is highly organized, keeps strong records, and works well across teams\n\nStrong work ethic and willingness to stay close to the bench, including routine work when needed\n\nAble to learn quickly and work effectively in a fast-moving startup environment\n\nExperience in reproductive biology, ovarian development, or germ cell biology is a plus\n\nWhy join us\nImpact: Own one of Conception’s most critical preclinical programs, with the potential to transform human reproduction\n\nGrowth: Develop and lead a small team and expand scope as the program scales\n\nCommunity: Work alongside passionate scientists tackling one of the most exciting frontiers in biology with a deeply aligned team\n\nMission: 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\n\nCome and work with us\nWe are well funded and well connected in Silicon Valley. We offer competitive pay, company equity, and excellent healthcare benefits for these positions.\nTo learn more about the original mouse proof of concept to live birth that inspired us, see https://www.nature.com/articles/nature20104","description_format":"text","description_chars":5193,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cell & Gene Therapy","Fertility & IVF"],"lifecycle":[{"event":"open","at":"2026-09-05T18:02:25Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.243,"p_room":0.28,"age_days":175,"expected_fill_days":30,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-11-04T06:34:25Z"},"pay":null,"html_url":"https://alion.io/job/conception-senior-scientist-organoid","json_url":"https://alion.io/job/conception-senior-scientist-organoid.json","meta":{"generated_at":"2026-11-04T18:54:28Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":29085,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":100012},"rest":"https://alion.io/mcp/rest/get_company?id=100012"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fconception-senior-scientist-organoid"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fconception-senior-scientist-organoid"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fconception-senior-scientist-organoid"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/conception-senior-scientist-organoid\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fconception-senior-scientist-organoid"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":340268}},{"tool":"search_jobs","arguments":{"company":"conception.bio","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":340268},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
