Purpose: The Associate Director, will integrate target biology insights with state of the art recombinant expression screening and analytics to streamline and accelerate protein production for assay development, high-throughput screening (HTS), pharmacological profiling, biophysics and structural biology (X-ray crystallography, Cryo-EM, HDX-MS and NMR) to advance discovery portfolio. As a key member of the Structural and Protein Sciences group, this position will play a critical role in partnering with the Protein Chemistry, Biophysics and Structural Biology teams to contribute towards protein design & engineering, streamlining recombinant protein expression and production of novel protein targets and applying innovative tools to express the most complex targets including membrane proteins to accelerate target-to-lead timelines We are seeking a scientifically thorough and collaborative leader who can work across discovery teams to drive impact across a diverse portfolio of. Success will require the ability to operate effectively within a highly matrixed, fast-paced environment, while contributing both strategically and hands-on to program advancement. You will be responsible to: Lead, mentor, and manage a team of scientists and associate scientists responsible for high-throughput expression screening across bacterial, insect, and mammalian expression systems, including performance management and career development conversations. Define and execute the strategic vision for the HT expression screening platform, aligning capacity, automation investment, and technology roadmap with departmental and portfolio priorities. Design and implement high-throughput construct and expression screening strategies to rapidly identify optimal expression conditions for challenging soluble and membrane protein targets. Drive automation of expression screening workflows using liquid-handling robotics and laboratory information management systems to increase throughput, reproducibility, and data quality. Partner with Therapeutic Area discovery teams, Protein Chemistry, and Structural Biology leads to translate program needs into feasible expression screening plans, timelines, and risk-mitigation strategies. Evaluate, pilot, and implement new technologies and platforms (e.g., novel expression hosts, cell-free systems, AI/ML-guided protein screening) to continuously improve screening throughput and success rates. Oversee data analysis, interpretation, and reporting of expression screening results, ensuring timely, data-driven recommendations are communicated to project teams and management. Manage vendor and CRO relationships for externalized expression screening activities, including technology transfer, scope definition, and quality oversight. Ensure compliance with Environmental Health & Safety (EHS), Electronic Lab Notebook (ELN), and other regulatory/documentation standards.
