Flagship Labs 111: Cell Biology Co-Op

What you'd do

• Cell lines consistently maintained and used with sound culture practice and documentation.
• PD datasets with appropriate vehicle and positive/negative controls, documented replicates, and fit-for-purpose data-quality checks.
• Clear analysis and interpretation of concentration-response and PD data.
• Protocols documented well enough for another scientist to reproduce.
• Complete, traceable ELN records from planning through analysis.
• Clear communication of findings, limitations, and recommended next steps.
• Growing independence in design, execution, troubleshooting, and interpretation.

What they want

• Pursuing a BS or MS in Biology, Cell Biology, Molecular Biology, Biochemistry, Biomedical Sciences, or related field.
• Hands-on mammalian cell culture experience, ideally with cancer cell lines.
• Experience running controlled cell-based experiments with small-molecule compound treatment.
• Hands-on experience with at least one of: Western blotting, qPCR, ELISA, cell proliferation/viability assays.
• Working knowledge of experimental controls, replicates, dilution calculations, and basic quantitative analysis.
• Strong attention to detail and commitment to reproducible, high-quality data.
• Ability to follow and write protocols, and maintain accurate documentation.
• Ability to work independently at the bench while flagging observations, unexpected results, and uncertainties promptly.
• Strong organizational and communication skills; comfortable in a multidisciplinary research environment.

What you get

• Build alongside founders. You’ll work inside the same hypothesis-driven process Flagship uses to conceive and launch first-in-category companies.
• This can be the start of a longer story. Strong co-ops are considered for future opportunities across Flagship and its portfolio companies, not just for this one role.
• Work alongside people who left the safe path. Your colleagues are scientists, engineers, and operators who chose to build something new rather than join something already established.
• Take on real ownership. You're contributing to ventures that are still being defined. Your work can shape real decisions, not just support them.
• Be paid like the contributor you are. Compensation reflects the real work you take on.
