About the Job

Requirements

  • A bachelor's degree in a relevant scientific area is required.
  • For the Lead Researcher level, at least 5 years of research experience is required; 3 years are required with a master's degree, and no prior experience is required with a PhD.
  • For the Senior Researcher level, 2 years of research experience are required; no prior experience is required with a master's degree.
  • Working knowledge and understanding of underlying concepts and principles of experimental design.
  • Experience with the most widely used techniques in the home laboratory.
  • Demonstrated performance in an earlier or comparable role.
  • Strong knowledge and experience applying the underlying principles related to techniques being performed.
  • Proficiency with humanized research models, highly immunocompromised strains such as NBSGW, and/or specialized disease models such as Townes.
  • Hands-on proficiency with multi-color flow cytometry and Magnetic-Activated Cell Sorting (MACS) to isolate, characterize, and analyze hematopoietic and immune cell populations.
  • Experience handling and preparing human Hematopoietic Stem Cells (HSCs), including precise in vivo delivery or transplantation.
  • Experience supporting welfare-focused research practices, regulatory compliance, and protocol refinement to enhance care standards and minimize distress.
  • Experience with specialized software systems and databases for meticulous record and data maintenance, including flow cytometry analysis software.
  • Proven performance and leadership in a comparable high-level research role.

Responsibilities

  • Lead and execute complex in vivo studies using specialized humanized and disease-relevant research models, including immunocompromised and hemoglobinopathy models, to evaluate therapeutic genome engineering outcomes.
  • Isolate, phenotypically characterize, and prepare human Hematopoietic Stem Cells (HSCs) and targeted cell populations using Magnetic-Activated Cell Sorting (MACS) and multi-color flow cytometry.
  • Prepare, engraft, and maintain advanced humanized research models for translational studies.
  • Administer experimental therapies using advanced in vivo delivery approaches and minimally invasive techniques that support scientific rigor and animal welfare.
  • Conduct specialized procedures, including aseptic sample collection, precise dosing, and downstream molecular and flow cytometric analyses, as applicable to study design.
  • Refine protocols to minimize stress, support environmental enrichment, and implement appropriate humane endpoints.
  • Collaborate with veterinary staff, Animal Resource Center (ARC) personnel, and research teams to ensure specialized research models receive high standards of care and oversight.
  • Ensure procedures comply with institutional policies, applicable regulatory requirements, the ILAR Guide for the Care and Use of Laboratory Animals, and the USDA Animal Welfare Act, incorporating the principles of Replacement, Reduction, and Refinement (3Rs).
  • Maintain transparent documentation for studies, including health monitoring, engraftment outcomes, flow cytometry data, and observational records.
  • Guide and mentor early-career team members on standard procedures, welfare-focused handling, MACS and flow cytometry operation, and specialized HSC protocols.
  • Develop, optimize, and implement refined in vivo methodologies, minimally invasive treatment approaches, and downstream cellular assays.
  • Support planning and procurement of specialized supplies, reagents, and antibodies for humanized models and complex in vivo studies.
  • Maintain regular and predictable attendance to support continuity of ongoing studies and research activities.

Desired Qualifications

  • A master's degree or higher is heavily preferred.
  • Experience in research and development methods and processes in a laboratory setting, and executing laboratory research projects, is preferred.

About the Company

St. Jude Children's Research Hospital

Pediatric cancer treatment and research nonprofit

St. Jude Children's Research Hospital is a nonprofit pediatric treatment and research center focused on childhood cancers, especially leukemia. It treats patients while covering medical costs, travel, housing, and food, so families are never billed. Care combines clinical treatment with research that develops new therapies, and findings are shared openly with doctors worldwide. Its goal is to cure childhood cancer, relieve families of financial burden, and accelerate progress by sharing knowledge globally.
