We are seeking an accomplished Senior Principal Research Scientist in Computational Chemistry with significant pharmaceutical industry experience to join our multidisciplinary small molecule drug discovery organization. This is a senior individual contributor role for a highly experienced computational chemist with a strong track record of advancing pharmaceutical discovery programs through hands-on scientific impact.

The successful candidate will support discovery project teams across target identification, hit discovery, lead optimization, and drug candidate selection. The role requires a high degree of independence, technical depth, and scientific judgment. The candidate will apply modern computational chemistry approaches to directly inform medicinal chemistry design and project decision-making. We are looking for a creative, detail-oriented scientist with a passion for drug discovery and a collaborative mindset.

As part of the drug discovery team, the candidate will contribute directly to target assessment and druggability analysis, perform virtual screening and structure-based modeling, and work closely with medicinal chemists to design compounds with improved potency, selectivity, functional activity, and develop ability (e.g., ADME/DMPK). In addition to hands-on contributions, the candidate will mentor other scientists and share best practices to amplify the impact of computational chemistry across project teams.

This position is based in our South San Francisco headquarter office and required to be onsite four days per week per our company policy.

Location:

South San Francisco, CA.
