About Ambrx:

Ambrx is a biopharmaceutical company enabling a new field of protein medicinal chemistry, using a fundamentally new technology that directs incorporation of amino acids beyond nature’s conserved set into biosynthetic proteins to produce high value biologics products.

Ambrx is seeking a highly-motivated bioassay scientist to be a key member of the Translational Sciences team. The successful candidate will be primarily responsible for developing ELISA and cell-based potency assays for antibody drug conjugates (ADCs) and managing GMP CROs.  

Responsibilities:

•   Develop and pre-qualify cell-based potency assays and antigen binding ELISA methods.
•   Apply Design of Experiments (DOE) to identify and optimize critical assay parameters.
•   Set stage-appropriate systems suitability and acceptance criteria.
•   Utilize PLA 3.0 software to perform parallel line analysis (equivalence testing).
•   Interview GMP CROs, negotiate quotes, and perform audits to evaluate technical capabilities.
•   Manage CROs to ensure bioassay methods are transferred and qualified within timelines for GMP lot release testing.
•   CRO oversight to ensure stability sample testing occurs within specified time frames, new critical reagent lots are qualified for use, and any deviations, investigations, or CAPAs are resolved.
•   Monitor bioassay performance and trend GMP DS and DP batch stability data.
•   Represent bioassay function at project CMC subteam meetings.
•   Perform non-GMP potency assay sample testing to support program needs.
•   Write Development reports, memos, and relevant CMC sections for regulatory submissions.
•   Present work and effectively communicate progress at meetings.

Requirements


•   Ph.D. (or MS) in Cell Biology or a related scientific discipline with >3 years of industry experience in the bioassay field. (title commensurate with experience)
•   Extensive, hands-on experience in bioassay methods optimization, qualification, and validation.
•   Prior experience auditing and managing GMP CROs for bioassay testing.
•   Proficient at using JMP, Design of Experiments (DOE), and PLA 3.0 software.
•   Knowledge of relevant ICH and USP chapters, GMP requirements, and industry best practices.
•   Demonstrated capability to work with team members to troubleshoot and identify solutions.
•   Prior experience working with ADCs or bispecific molecules is desirable.
•   Ability to work effectively in a goal-oriented, fast-paced, matrixed team environment.
•   Flexibility to contribute to other functional areas is desirable.

To be considered as an applicant, please submit your resume/CV referencing the specific position of interest.
