We give our best effort to our work, and we put people first. We’re looking for people who are determined to make life better for people around the world. As a scientist in the Large Molecule Biology group, you will be joining a large and dynamic group focused on executing experiments on the cutting edge of pharmaceutical sciences. You will execute experiments needed to support the various research programs for identified targets. You will oversee aspects of portfolio programs independently and with minimal direct oversight. You will be expected to demonstrate laboratory expertise with biologic assays aimed at drug development (mAb, ADC and CD3 platforms). In addition, assay development for specialized assays related to portfolio programs is required. You will also be encouraged to develop your own ideas and contribute these to the broader group. You are expected to be a dynamic and motivated scientist who can drive their own experiments and research activities, while collaborating extensively with the rest of the organization to execute on various research programs.

Manage the maintenance, culture, and passaging of multiple cell lines to support experimental objectives. Perform comprehensive functional assays and high-throughput screenings, including tumor cell signaling, internalization, cytotoxicity, effector function and cytokine release assays, to assess cellular responses. Conduct multi-parameter flow cytometry assays to determine binding interactions and accurately quantify receptor density across diverse cell populations. Conduct candidate evaluation in both in vitro (PK/PD, receptor occupancy, density, cytokine release), and ex vivo assays (tumor isolation, analysis of blood cells). Develop, validate, and perform bioanalytical assays—including ELISA—to precisely quantify proteins and antibodies relevant to experimental outcomes. Critically assess and monitor experimental procedures performed by third-party collaborators and vendors to ensure compliance with study protocols and quality standards. Work with the project leader and senior leader to design and execute assays for the development of the molecule. Present your work to internal teams and summarize findings in preclinical reports. Communicate results at project team meetings, be involved in the coordination and preparation of presentations. Discuss results with technical as well as non-technical personnel. Work in cross functional environments via extensive collaboration with other parts of the organization.
