About the role
Looking to join a passionate team dedicated to developing and manufacturing life-saving biopharmaceuticals? Avid Bioservices is a leading clinical and commercial biologics CDMO focused on creating innovative solutions to meet the needs of our clients and improve patient outcomes.
Your Role:
Avid is seeking a highly motivated and technically strong Sr. Scientist, Downstream and Biologics Formulation Development to lead biologics formulation development while contributing to integrated downstream process development within a fast-paced, client-facing environment. This role is responsible for defining formulation strategies, executing technical studies, and supporting cross-functional integration as the capability expands. Additional responsibilities include designing downstream purification processes for protein-based biologics, viral clearance studies, scale-down and scale-up activities, and technology transfer to manufacturing. The individual will collaborate closely with Cell Line Development, Upstream Process Development, Analytical Sciences, MSAT, DS/DP Manufacturing, Program Management, and external partners to support client programs.

The individual will collaborate closely with Cell Line Development, Upstream Process Development, Analytical Sciences, MSAT, DS/DP Manufacturing, Program Management, and external partners to support client programs.
Key Responsibilities:
- Lead formulation development for biologics, including pre-formulation assessments, excipient screening, and stability studies. Demonstrated experience in formulation development for complex biologic modalities—including antibody–drug conjugates (ADCs)—with understanding of modality-specific stability and developability challenges is highly advantageous.
- Lead downstream process development for biologics, including capture chromatography, polishing chromatography, viral inactivation/filtration, and tangential flow filtration (TFF).
- Extensive hands-on experience with analytical techniques for protein characterization, including DLS, DSF, SEC, CE, rheology, and spectroscopy. Design and interpret analytical testing strategies including HPLC (SEC & IEX), CE-SDS, SDS-PAGE, UV spectroscopy, and other biophysical assays to support process development and formulation studies.
- Expertise in developing high concentration protein formulations and resolving issues such as aggregation, viscosity, and solubility. Able to identify and mitigate formulation risks including precipitation and chemical degradation.
- Design experiments, analyze data, and prepare technical protocols, reports, and development summaries.
- Establish and drive scientific strategy, workflows, and best practices for early- to late-stage biologics formulation development, with the ability to operate independently in a dynamic, fast-paced, client-facing environment with evolving priorities.
- Serve as a technical subject matter expert (SME) in client engagements, including proposals, presentations, and project reviews; prior line management or informal leadership experience is advantageous.
- Collaborate effectively with cross-functional teams to align project timelines, priorities, and resource planning.
- Mentor and develop junior scientists and technical staff, and support onboarding of new team members.
- Evaluate and implement new technologies and platform approaches to enhance internal capabilities and drive innovation.
- Ensure compliance with applicable quality, regulatory, and safety standards.
- Perform additional responsibilities as required to support evolving business and project needs.
- Occasional travel may be required (by land or air) to attend conferences, seminars, off-site client meetings, and marketing events as needed.
Minimum Qualifications:
- Master’s degree/PhD degree in Biochemistry, Chemistry, or related field and minimum 4-6 years of relevant experience and demonstrated working knowledge of scientific principles.
- Prior experience in formulation development, stability studies, and analytical characterization of biologics or strong background in biochemical and biophysical characterization of proteins with deep understanding of protein structure and function.
- Experience in development of ultra-high concentration and pre-developability assessment
- Proven record of strong technical writing and communication skills.
- Ability to thrive in a dynamic, cross-functional environment
