Job Description

About Us

We’re a stealth-mode, venture-backed biotech startup based in the Bay Area, developing breakthrough technology at the intersection of genetics and sperm health. We’re backed by world-class investors, just raised our first institutional round, and now we’re hiring a specialized scientist to lead our R&D.

About the Role

We’re looking for a Founding Scientist to further build and develop our flow cytometry-based platforms. The ideal candidate will have extensive expertise in flow cytometry, particularly in assay design, data analysis, and working with challenging cell types. This is a hands-on, high-impact role at the earliest stage of the company; perfect for someone excited to shape the future of fertility and reproductive health.

Responsibilities

  • Design, optimize, and execute flow cytometry-based experiments
  • Develop and validate live-cell assays
  • Analyze, interpret, and be able to present experimental data
  • Contribute to protocol development, documentation, and future IP filings
  • Help shape the scientific direction and culture of the company as a founding team member

Qualifications

  • PhD (or equivalent experience) in molecular biology, bioengineering, cell biology, or related field

Required Skills

  • Extensive, hands-on experience with flow cytometry is required - you have independently designed, optimized, and analyzed flow-based assays, and can troubleshoot signal, gating, and viability challenges
  • Strong track record of designing and troubleshooting live-cell experiments
  • Familiarity with small or fragile cell types (e.g., stem cells, primary cells)
  • Comfortable working in a fast-paced, early-stage environment with evolving goals
  • Excellent communication and organizational skills
  • Mission-driven, self-directed, and excited to build from the ground up

Preferred Skills

  • Experience working with sperm cells
  • Background in reproductive biology, IVF, or embryology
  • Prior startup or technology development experience

Pay Range and Compensation Package

This is a full-time, on-site role based in the San Francisco Peninsula, CA.

  • Salary range: $100,000–$140,000, with potential to go higher for the right candidate
  • Equity: Meaningful early-stage equity as part of the founding team

Equal Opportunity Statement

We’re committed to building a diverse and inclusive team. We welcome applicants of all backgrounds, experiences, and identities. We do not discriminate on the basis of race, color, religion, sex (including pregnancy, sexual orientation, and gender identity), ancestry, marital status, national origin, religion, age, disability, genetic information, veteran status, or any other protected status under applicable laws.
