Research Associate, Cell Line Development Automation

Prolific Machines is ushering in a new era of biotechnology with light. Our first-of-its-kind optogenetic platform delivers unprecedented control, precisely guiding cellular behavior when and where it matters most. Unlike existing tools used to control biology, our technology enables dynamic, tunable control over virtually any cellular function in any cell type. We're enabling partners to unlock robust efficiency, quality, and reproducibility advantages across the most complex pharmaceuticals and therapeutic proteins. Prolific is supported by leading investors, including Bill Gates’s Breakthrough Energy Ventures, Mayfield and SOSV. We are seeking a motivated Research Associate II or Senior Research Associate to join our Automation/Cell Line Development (CLD) team, with a focus on laboratory automation and high-throughput workflows. In this role, you will develop and optimize automated workflows to support cell line development, contribute to pipeline projects, and conduct experiments to improve the performance of our optogenetic Chinese Hamster Ovary (CHO) cell lines. You will work at the intersection of laboratory automation, cell culture, and molecular biology, helping improve the efficiency, scalability, and reproducibility of our CLD processes. This role is based on-site at our headquarters in Emeryville, CA. \n Responsibilities:

Conduct experiments independently, collect and analyze data in a timely manner, and maintain detailed documentation in electronic lab notebooks. Conduct experiments at the Automation/CLD interface and establish efficient automation workflows (Tecan or Hamilton) for CLD processes during seed train, production, or screening (Ambr or Beacon) processes. Communicate successfully with any team, demonstrating the ability to compile and present across different teams and forums within the company. Quickly analyze and provide critical data and figures to support presentations, patent applications, or publications. Collaborate closely with members of the CLD team as well as other teams within Prolific Machines. Contribute to lab maintenance and safety as a good lab citizen. Develop and optimize analytical methods, ensuring adherence to safety and operational standards, following established protocols, and providing data for regulatory submissions. This is a lab-based position, and onsite presence is required as dictated by Automation and Cell Line Development (CLD) responsibilities and experimental needs. About You:

Qualifications: Education & Experience : A Bachelor's degree with 2-5+ years of relevant industry experience or a Master's degree with 1-4+ years of relevant experience is expected for an RA II position. Additional experience and increased independence expected at the Sr. RA level.
