**Kelly Science and Clinical** is the worlds most recognized brand in science and clinical staffing with more than 100 locations in North America, Europe, and the Pacific Rim. Our scientists contribute to the research and development of the next generation of small molecule drugs, biologics and cellular therapies.


We are seeking a Scientist, Antibody Engineering for one of our clients, a startup biotechnology company that specializes in manufacturing cell and gene therapies for cancer patients around the world. The incumbent will assist with genetic engineering of lentiviral vectors expressing antibodies and CAR and in vitro assays. The candidate will focus on the Discovery of Antibody based biologics and T/NK cell products as well as assist with planning and execution of experiments, in support of developing analytical methods for releasing and characterizing T cell therapy products. Candidates with strong expertise in phage display library construction and antibody engineering will be given preference. The successful candidate will demonstrate a strong sense of responsibility, open communication, desire to learn new skills, ability to meticulously perform instructed tasks and maintain lab records. S/he will perform bench work to support research projects in coordination with our scientific director. We are looking for enthusiastic individuals with a flexibility to adapt to startup environment.


+ Use expertise in molecular biology to generate Chimeric Antigen Receptor (CAR) or antibody constructs.

+ Engineer lentiviral vectors with insertion or deletion of restriction sites, epitope tags or other genetic elements.

+ Generate viral vectors expressing scFv or CAR variants, site directed mutants, and fusion proteins using fusion PCR and Gibson or other fragment assembly methods.

+ Design and clone shRNA, gRNA for desired targets in CRISPR/Cas9 vectors.

+ Design strategies to knock-in CAR in T cells

+ Perform antibody phage display screens and validation of clones by ELISA and flow cytometry.

+ Express/Purify antibodies and recombinant proteins in bacteria or mammalian cells.

+ Develop biochemical, cell based and immunoassays to evaluate antibody binding affinities

+ **Experience in phage display library construction, antibody engineering, humanization or affinity maturation of antibodies are preferred.**

+ Strong technical skills in advanced molecular cloning and fragment assembly techniques are required

+ Strong experience in cell based and biochemical assays are required must be able to perform assays in 96 and 384 well formats with different formats without confusion.

+ Experience in working with multiple cell lines (both suspension and adherent) and setting up cell-based assays.

+ General lab experience in operating and maintaining basic lab equipment (centrifuge, microscope, PCR machines, nanodrop, DNA and protein electrophoresis systems).

+ Hands on experience with sterile microbiology and molecular biology techniques not limited to cloning, mutagenesis, restriction digestion, ligation, transformation, colony PCR, culturing bacterial cells, plasmid preparations.

+ Critical to have the ability to maintain accurate records and back track samples prepared without confusion.

+ Prior experience in optimizing and trouble-shooting qPCR and ddPCR

+ Communicate ideas and results clearly and effectively (both verbally and in writing) to the team members.

+ Must feel comfortable in a fast-paced small company environment with minimal direction and able to adjust workload based upon changing priorities
