CFD Research is seeking a highly motivated scientist to join our Biotechnology and Life Sciences team, where they will play a critical role in advancing viral infection systems and in‑vitro models to better understand host–pathogen interactions and support antiviral development. The successful candidate will leverage hands‑on expertise in mammalian cell culture, viral production, and molecular biology to design and execute experiments involving infectious agents, generate and validate viral stocks, and develop robust cell‑based assays.

This position offers the opportunity to contribute to cutting‑edge research in a fast‑paced, collaborative environment, with a strong emphasis on scientific rigor, biosafety, and high‑quality data generation to support both internal programs and external partnerships.

• Design and execute experiments for developing/optimizing viral infection models
• Perform virus production, titration, and quality control, including functional validation of viral stocks using standard quantitative methods
• Maintain and culture a variety of mammalian cell lines; perform transduction, transfection, infection assays, and stable cell line generation
• Develop and optimize in‑vitro infection models and cell‑based assays to characterize viral replication, antiviral potency, tropism, and host‑pathogen interactions
• Execute molecular biology workflows including PCR, cloning, sequencing verification, Western blotting, ELISA, and fluorescence‑based assays
• Contribute to antiviral screening and functional assay development as needed
• Maintain BSL‑2 compliant laboratory practices; follow all biosafety protocols and contribute to a strong lab safety culture
• Document experimental work thoroughly; contribute to internal technical reports, SOPs, and scientific publications

• Candidate must be a US Citizen and meet eligibility to obtain (and maintain) a Secret Clearance
• MS in Virology, Microbiology, Molecular Biology, Biomedical Science, or a closely related field
• 5+ years of experience in developing viral infection models
• Hands‑on experience working with mammalian viral systems (VEEV, LASV, influenza, coronaviruses, or similar)
• Proficiency in mammalian cell culture, including sterile technique, passaging, transfection, and infection assays
• Experience with virus production and titration (e.g., plaque assays, TCID
  50, qPCR‑based titration, or ELISA)
• Solid foundation in core molecular biology techniques (PCR, cloning, gel electrophoresis, sequencing, Western blot, ELISA)
• Strong attention to detail, laboratory organization, and commitment to rigorous data documentation
• Ability to work both independently and collaboratively in a small, fast‑paced team

• Experience with BSL‑2 or BSL‑3 containment and associated biosafety training
• Experience with animal models of viral infection
• Background in host‑pathogen interaction studies or innate immune response characterization
• Hands‑on experience with pathogen infection in complex in‑vitro models
• Demonstrated success in grant or proposal writing
