Scientist, Cell Engineering & Screening

About us

e184 Repro is a biotechnology research company with the mission of advancing in vitro gametogenesis to solve one of biology’s most profound challenges: returning the fundamental right to procreate.

We work at the frontier of cutting-edge technology, integrating cellular reprogramming, machine learning-guided optimization, multi-omics analysis, and automated experimental workflows to enable gamete development for individuals facing reproductive challenges.

Role overview

As a Scientist at e184 Repro, you will own high-throughput screening campaigns from end to end - designing experiments, executing them at the bench, analyzing results, and iterating to drive discovery. Reporting to the CSO, this is a high-impact, hands-on role for an independent scientist who excels at translating experimental data into actionable insights in a well-funded startup environment where your science directly enables breakthrough discovery.

• Engineer reporter systems: Design, generate, and validate CRISPR-based reporter lines and develop quantitative cellular assays hands-on to enable robust phenotypic screening readouts.
• Own screening end-to-end: Design TF screening experiments (pooled and arrayed), construct screening libraries, execute experiments at the bench, and manage sample processing through hit validation.
• Drive the discovery cycle: Analyze screening data to identify hits, validate candidates through arrayed experiments, characterize mechanisms of action, and design next-iteration screens.
• Collaborate across disciplines: Partner with bioinformaticians on experimental-computational workflow integration and with biology experts to ensure screening readouts capture biologically meaningful phenotypes.

• PhD in Cell Biology, Molecular Biology, Genetics, Biochemistry, or related field
• Hands-on high-throughput screening experience (pooled and/or arrayed) with mammalian cells, including iPSCs
• CRISPR/Cas9 genome editing and reporter development expertise
• Strong molecular biology foundation (cloning, plasmid design, library construction) and quantitative assay development
• Flow cytometry or high-content imaging for cellular analysis
• You are reliable, adaptable, and ready to tackle occasional weekend maintenance to keep the science moving

• Industry R&D experience in biotech or pharmaceutical settings
• Track record of end-to-end screening project ownership - from design through execution and validation
• Experience with high-throughput automation or liquid handling
• Hands-on sequencing experience (scRNA-seq, ATAC-seq) including library prep, plus proficiency with bioinformatics tools
• Immunofluorescence microscopy and imaging

• Unrivaled impact: Your work directly enables technology that transforms human fertility and reproductive medicine.
• Full-spectrum growth: Gain exposure to the entire lifecycle of discovery. From screening to mechanistic validation.
• Best of both worlds: Experience the creative chaos of an early-stage startup with the stability of a well-capitalized company.
• Elite collaboration: Work alongside a world-class team who are as driven as you are.

• Competitive salary + equity participation is considered
• State-of-the-art facility in Portland metro area
• Comprehensive Medical, Dental, Vision, and 401(k) with company match
• 20 days PTO + 11 paid holidays
