Computational Chemist

Topos Bio

At Topos Bio, we're pioneering drug discovery for intrinsically disordered proteins-targets that have eluded conventional approaches in neurodegeneration, oncology, and cardiometabolic disease.

We're seeking a Computational Chemist to help generate novel molecules for a variety of targets and collaborate closely with AI researchers and experimental scientists.

What you will do

• Develop scalable workflows to generate and screen thousands of potential drug candidates
• Design and run molecular dynamics simulations, applying enhanced sampling methods to characterize protein-ligand binding and conformational dynamics

• Engineer and optimize data pipelines that handle large-scale molecular simulations and structure-based predictions
• Build and optimize cheminformatics pipelines for compound filtering, property prediction, fingerprint-based similarity search, and chemical space analysis
• Collaborate with AI researchers to incorporate simulation data into model training and inference pipelines
• Bridge scientific rigor with practical results, ensuring computational protocols are both accurate and efficient
• Communicate technical nuances to cross-functional teams, fostering a shared understanding of capabilities and limitations
• Stay up to date with the latest research and breakthroughs in computational chemistry, generative models, and molecular simulation
• Lead external scientific presentations to pharmaceutical partners; Communicate the team's computational approaches for both technical audiences and business partners

What we are looking for

• PhD in Computational Biophysics, Computational Chemistry, or a related field
• Experience with molecular modeling, simulation, and generative drug design
• Proficiency with common computational biophysics software (e.g. AMBER, GROMACS, OpenMM, PLUMED, Schrödinger, OpenEye)
• Strong background in cheminformatics: molecular fingerprints, QSAR/QSPR, property prediction, scaffold analysis, cheminformatics libraries (e.g., RDKit, OpenBabel)
• Expert coding in at least one language (Python preferred)
• Familiarity with HPC cluster or cloud computing environments, containerization, and workflow orchestration
• Strong communication skills, with the ability to present complex ideas in clear terms

Preferred

• Experience integrating machine learning techniques for molecular generation
• Background in quantum chemistry methods (DFT, ab initio) and its application to biomolecular systems
• Exposure to early-stage drug discovery programs, from target identification to lead optimization
