Our mission is to unlock new possibilities for fertility, reproductive health, and genetic diversity. We are building a world-class team to make this vision a reality.\nThe role:\nWe are looking for an experienced stem cell scientist who genuinely enjoys maintaining and handling human pluripotent stem cells and wants to build a career doing this work extremely well.\nThis person should take real ownership of culture quality. You should have strong judgment around what healthy cultures look like, notice when something is starting to go wrong, and have a “do no harm” mindset around handling sensitive cells and minimizing unnecessary stress.\nA big part of the job is also the discipline that comes with good cell culture: careful documentation, tracking culture history, maintaining cell banks, following QC closely, and working to reduce batch-to-batch variability as much as possible. We want someone who enjoys this part of the work too and takes pride in being meticulous.\nThis is a very hands-on role. We are specifically looking for someone who likes being at the hood, likes caring for cells, and wants to become exceptionally good at it.\nAvailability for the Sunday-Thursday schedule is critical to our workflows, and we offer a salary adjustment for this schedule.\nWhat you’ll do:\nMaintain human iPSC/ESC cultures: Culture, passage, expand, freeze and thaw sensitive stem cell lines while maintaining consistently high culture quality.\n\nOwn culture quality: Develop strong judgment around morphology, confluency, differentiation, recovery and overall culture health, and identify problems early.\n\nMinimize culture stress: Handle cells carefully and consistently, paying attention to small differences in technique that can affect quality and downstream performance.\n\nReduce variability: Help make our stem cell workflows as consistent and reproducible as possible across operators and batches.\n\nSupport cell banks and QC: Maintain cell banks and perform routine QC, including mycoplasma and sterility testing, characterization and sample preparation for whole-genome sequencing.\n\nPerform directed differentiations: Run routine differentiations with careful attention to timing, handling and outcome tracking.\n\nImprove processes: Help stabilize protocols, define QC standards and ultimately contribute to process development for our stem cell workflows.\n\nDocument everything well: Maintain clear, accurate culture records, track deviations and outcomes, and help ensure that culture history is easy to understand and trace.\n\nPrepare critical reagents: Prepare media, small molecules and other cell culture reagents consistently and carefully.\n\nExperience:\nBachelor’s, Master’s, or PhD in biology, stem cell biology, or a related field\n\nHands-on experience maintaining human iPSC and/or ESC cultures\n\nIndustry experience strongly preferred\n\nStrong sterile technique and excellent judgment around healthy versus poor-quality stem cell cultures\n\nStrong attention to detail, documentation, and record-keeping\n\nExperience working to improve consistency and reduce batch-to-batch variability\n\nPrior hands-on flow cytometry experience\n\nComfortable with repetitive, detail-oriented work where consistency really matters\n\nSomeone who genuinely enjoys tissue culture and wants this to be a meaningful part of their long-term career\n\nPositive attitude and strong team mindset\n\nWe are open to candidates across the Senior Research Associate / Associate Scientist range, including PhD-level candidates. Level and title will be based on relevant experience, technical depth, and demonstrated independence.\nWhy join us:\nImpact: Be part of a high-reliability stem cell core that underpins our preclinical pipeline, with the potential to transform human reproduction\n\nGrowth: Gain experience with cutting-edge stem cell culture methods and QC approaches\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","description_format":"text","description_chars":4308,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cell & Gene Therapy","Regenerative Medicine","Fertility & IVF"],"lifecycle":[{"event":"open","at":"2026-09-05T18:02:25Z"}],"visa":[],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.297,"p_room":0.28,"age_days":76,"expected_fill_days":24,"reasons":["conf:1","win:tail","crowd:junior"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/conception-senior-research-associate-stem-cell-biology","json_url":"https://alion.io/job/conception-senior-research-associate-stem-cell-biology.json","meta":{"generated_at":"2026-10-29T10:27:41Z","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":15877,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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-research-associate-stem-cell-biology"},{"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-research-associate-stem-cell-biology"},{"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-research-associate-stem-cell-biology"},{"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-research-associate-stem-cell-biology\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fconception-senior-research-associate-stem-cell-biology"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":340263}},{"tool":"search_jobs","arguments":{"company":"conception.bio","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":340263},"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.
