Senior Scientist, RNA Delivery

Responsibilities

• Develop RNA delivery workflows for payload expression in different cell types and culture set ups. Apply RNA delivery strategies to improve and accelerate Conception's differentiation platform.
• Optimize RNA format, delivery chemistry and formulation, dose, timing, repeat delivery, expression, viability, and biological activity.
• Build assays to measure delivery efficiency, target expression, and differentiation outcomes. Support screening workflows for RNA constructs, genes of interest, delivery conditions, and combinatorial perturbations.
• Collaborate across differentiation, cell engineering, and computational teams.

Requirements

• Required
• PhD or equivalent experience in RNA Biology, Cell Biology, Stem Cell Biology, Bioengineering, Synthetic Biology, Developmental Biology, or a related field.
• Hands-on experience delivering RNA into mammalian cells in various formats.
• Experience with most up to date RNA delivery technologies (LNPs, ligand conjugates, exosomes, electroporation, etc.) and standard readouts such as flow cytometry, imaging, qPCR, reporter assays, or RNA-seq.
• Experience delivering RNA or nanoparticles into complex culture systems.
• Experience optimizing delivery parameters such as dose, formulation, timing, repeat dosing, expression duration, toxicity, and biological effect.
• Strong experimental design, troubleshooting, documentation, and data interpretation skills.
• Preferred
• Experience with iPSCs, ESCs, primary cells, differentiating cells, or other difficult-to-transfect cell types.
• Experience using RNA-based differentiation approaches.
• Experience with different RNA format design, production, purification, characterization, or delivery.
• Experience with medium- or high-throughput screens, ORF libraries, combinatorial perturbations, or barcoded workflows.
• Familiarity with scRNA-seq or related single-cell approaches.
• Familiarity with developmental biology, reproductive biology, germ cell development, ovarian biology, or organoid systems.
• Come and work with us
• We are well funded and well connected in Silicon Valley. We offer competitive pay, company equity, and excellent healthcare benefits for these positions.
