Job Title:

Scientist - Cell Culture and Genetic Toxicology Job Description This Scientist role focuses on industry-based cell culture and genetic toxicology studies within a fast-paced, regulated contract research environment. You will maintain and evaluate healthy cell populations, perform in vitro assays, and support studies that contribute to cancer research, including work with animal models. The position requires hands-on experience with suspension cell lines, strong aseptic technique, and the ability to accurately document and interpret experimental data in accordance with Good Laboratory Practices. Responsibilities Maintain and manage healthy cell cultures, primarily suspension cell lines, with experience in adherent cell lines highly desirable. Monitor cell morphology, viability, growth characteristics, and cell density to assess overall cell population health and culture performance. Identify and respond to culture abnormalities, implementing appropriate corrective actions to preserve culture integrity. Perform cell treatments and exposures under varied conditions, including short- and long-term exposure periods, different incubation temperatures and environments, and varying cell densities and recovery intervals. Conduct cell harvesting procedures and sample preparation techniques for downstream analysis. Prepare microscope slides and analyze cellular samples, preferably using fluorescence microscopy, in support of genetic toxicology assays. Perform and document standard cell culture calculations, including Population Doubling (PD), Relative Population Doubling (RPD), and Relative Increase in Cell Count (RICC). Accurately record, interpret, and report experimental data in a regulated laboratory environment, adhering to Good Laboratory Practices. Recognize common cell culture contaminants, including bacterial, yeast, fungal, mycoplasma, and other microbial contaminants, and take steps to prevent and address contamination. Receive, evaluate, and process test articles submitted for testing in accordance with study requirements. Communicate and coordinate sample preparation and scheduling with scientific staff and Study Directors to ensure timely execution of studies. Determine surface area and calculate required extraction ratios for test articles submitted for testing. Prepare samples and dosing solutions using aseptic technique, following standard operating procedures and study protocols. Meticulously maintain precise records of all sample preparations and related activities in compliance with Good Laboratory Practices. Maintain a clean, organized, and safe work area, following all laboratory safety requirements. Safely wear a respirator when required by specific procedures or safety protocols. Run in vitro assays, including release testing and in vitro micronucleus (IVMN) assays, following established protocols. Review weekly study schedules and protocols to determine daily priorities and required activities. Participate in dosing studies in the vivarium, including recording body weights of animals and administering test articles as directed. Perform single injection dosing and observation of animals, including wrapping animals if needed, in support of study protocols. Contribute to reporting of study results and testing assay outcomes, ensuring clarity and accuracy. Support device preparation for testing, including disassembly, extractions, and preparation for ISO-compliant testing when required. Lead and mentor less experienced personnel on task execution, laboratory procedures, and good documentation practices. Work independently in a fast-paced environment, adapting to changing schedules and study demands while asking questions and seeking guidance when necessary. Essential Skills At least 3 years of industry-based cell culture experience, specifically with aseptic technique, outside of academic settings. Hands-on cell culture experience with suspension cell lines; experience with adherent cell lines is highly desirable. Demonstrated proficiency in aseptic technique and maintaining healthy cell cultures under a variety of conditions. Strong laboratory documentation skills and accurate data recording practices in a regulated environment. Ability to monitor cell morphology, viability, growth characteristics, and cell density, and to evaluate overall culture performance. Experience performing cell treatments and exposures with varying exposure durations, incubation conditions, cell densities, and recovery intervals. Experience with cell harvesting procedures and sample preparation techniques for downstream analysis. Ability to prepare microscope slides and analyze cellular samples, preferably using fluorescence microscopy. Proficiency in standard cell culture calculations, including Population Doubling (PD), Relative Population Doubling (RPD), and Relative Increase in Cell Count (RICC). Ability to accurately record, interpret, and report experimental data in accordance with Good Laboratory Practices (GLP). Capability to recognize and address common cell culture contaminants, including bacterial, yeast, fungal, mycoplasma, and other microbial contaminants. Experience with release testing and in vitro micronucleus (IVMN) assays. Bachelor's degree in Biology, Cell Biology, Molecular Biology, Toxicology, or a related life sciences discipline. Experience working in a contract research organization (CRO) or similar regulated laboratory environment. Strong understanding of cell growth kinetics and cellular biology. Ability to work effectively in a fast-paced environment with changing schedules and priorities. Comfort working with animals in support of studies aimed at advancing cancer research. Additional Skills & Qualifications Prior experience conducting in vitro micronucleus (IVMN) assays is preferred but not required; candidates with strong cell culture and cellular biology skills will be considered. Experience preparing test article and control formulations is desirable; training can be provided. Training will be provided for micronucleus identification and scoring using established historical image sets and internal laboratory procedures. Prior experience in GLP-regulated environments and genetic toxicology assays is a plus. Experience with assays, PCR, and general laboratory techniques is beneficial. Background in medical device testing, including device preparation, disassembly, extraction practices, and preparation for ISO-compliant testing, is advantageous. Experience leading or mentoring less experienced personnel in laboratory settings is beneficial. Strong organizational skills and attention to detail in maintaining clean workspaces and precise records. Ability to safely wear a respirator when required by specific procedures. Motivation to contribute to research that supports cancer treatment and advances human health. Work Environment This role is based in a contract research laboratory environment that supports both in vitro genetic toxicology assays and animal studies. The work is fast-paced, with schedules that can change frequently based on study demands and client needs, requiring flexibility and strong time management. You will work in a GLP-regulated setting with established standard operating procedures, using cell culture facilities, fluorescence microscopy, and other laboratory equipment. The environment includes a vivarium where animal dosing studies, body weight measurements, and observations are conducted as part of cancer-related research. Work may involve preparing and testing medical devices under ISO-related practices. Safety is a core focus, with strict adherence to laboratory safety requirements and the potential need to wear a respirator for certain procedures. The culture emphasizes independent, hands-on work, careful documentation, and collaboration with scientific staff and Study Directors. The position offers the opportunity to contribute directly to studies that aim to help cure cancer, within a professional research setting.
