4D Molecular Therapeutics, Inc. (“4DMT”) is a clinical-stage gene therapy company pioneering the development of product candidates using targeted and evolved AAV vectors. 4DMT seeks to unlock the full potential of gene therapy using its platform, Therapeutic Vector Evolution, which combines the power of directed evolution with approximately one billion synthetic capsid sequences to invent evolved vectors for use in targeted gene therapy products. The company is initially focused in three therapeutic areas: ophthalmology, cardiology, and pulmonology. The 4DMT targeted and evolved vectors are invented with the goal of being delivered through clinically routine, well-tolerated and minimally invasive routes of administration, transducing diseased cells in target tissues efficiently, having reduced immunogenicity and, where relevant, having resistance to pre-existing antibodies. 4DMT is currently conducting three clinical trials: 4D-125 is in a Phase 1/2 clinical trial for XLRP, 4D-110 is in a Phase 1 clinical trial for choroideremia and 4D-310 is in a Phase 1/2 clinical trial for Fabry disease.

4DMT is focused on attracting and retaining the best people in the industry who identify with our mission and innovative results-driven approach. We offer an inspiring and collaborative environment that encourages individual contributions, recognizes performance in multiple ways, offers competitive salary and benefits, and provides challenging opportunities for career development.  4D Molecular Therapeutics is located in Emeryville, CA.

4DMT needs a motivated, detail-oriented, and experienced Senior Research Associate I/II (Contactor). This individual will join a growing Cell-Based Assay (CBA) team to develop, execute, optimize, and validate cell-based bioassays for the characterization, lot release/stability testing and formulation assessment of AAV-based gene therapy drug substances and drug products. He/She will interface with Research, Discovery, Process Development, Manufacturing, Quality, and Facilities functional groups as well as external parties (CRO, CDMO) to support life cycle of bioassays for current and new candidates during early- and late-stage GMP production. This is a 9-month contract CMC position, and the level will be determined based on the candidate’s experience and qualifications. This position reports to Associate Director, Analytical Development and Quality Control.
