Job Description:

The Life Sciences Division of the Leidos Health Group is seeking a life scientist (biology, biochemistry, immunology, virology, bacteriology) to develop, assist with, and manage projects evaluating medical mitigations to infectious diseases.

Leidos Health focuses on developing scientific and medical solutions for the U.S. Government by integrating the efforts of subcontractors to provide a comprehensive solution to meet a key U.S. Government need. An individual with experience characterizing the immune response to vaccines and infectious diseases of humans is needed to support projects evaluating infectious diseases and developing vaccines/therapies to the diseases. The individual in this position will work independently and as part of a team developing medical countermeasures (such as small molecules, biologicals, vaccines, adjuvants). Projects may span from discovery (e.g., target discovery, candidate selection) and preclinical development using in vitro and in vivo models, to IND-enabling studies (e.g., toxicology) and early testing in humans (Phase I clinical trials). The successful candidate will bring a working knowledge of the development of medical countermeasures with an expertise in the analysis of the immune response (innate, T-cell, B-cell, humoral, and/or memory immune response) relevant to infectious diseases and medical countermeasure development.


  • Serve as a subject matter expert keeping current on scientific and technical literature for executing a broad range of immunological projects;

    • Meet organization requirements for schedule and finances;
    • Manage changes in project scope, schedule and/or budget, and drive risk management in collaboration with the customer to implement mitigation strategies;
    • Present data at internal and external meetings;
  • Write and edit manuscripts;
  • Design, conduct, and document in-vitro and in-vivo safety and toxicology studies to fulfill regulatory requirements and meet operational unit objectives.

Required Qualifications:

  • Demonstrated interpersonal, oral, written communication, and organizational skills;
  • Proficiency with Microsoft Excel/PowerPoint/Word as well as data analysis or statistical software;
  • Must be a U.S. citizen or permanent resident;

Preferred Qualifications:
