Senior Scientist

tl;dr

General Proximity is a seed-stage startup developing the next generation of induced proximity medicines (IPMs). Our OmniTAC drug discovery engine furnishes molecules that co-opt existing cellular machinery to overcome therapeutic challenges, which have remained unapproachable to other modalities for decades.

We are seeking a first-rate computational chemist to help us pioneer this uncharted frontier of drug discovery.

Our Story

A long-standing challenge in drug discovery is the development of molecules capable of modulating difficult or "undruggable" targets. Disease-causing proteins can be dysfunctional in many different ways, but our armamentarium for fixing them is quite limited. The most common mechanism of action for FDA-approved drugs is inhibition[1], but there are many other possible perturbation types whose potential remains unrealized.

General Proximity is a seed-stage drug discovery company developing a novel platform technology to solve this problem. We make bifunctional drugs that induce the modification of drug targets by existing cellular machinery (rather than through direct modulation by the drug, the classical approach).

Historically, the development of technologies that allow one to push new buttons in biology has been an incredibly fertile field for the discovery of new medicines[2, 3, 4], and our technology holds the same promise.

The Position

We are seeking an exceptional computational chemist to support our computational chemistry, cheminformatics, and molecular design efforts. This role will help drive small-molecule drug discovery programs by providing practical modeling support, applying modern computational workflows, and using the cheminformatics and AI-enabled tools that empower medicinal chemists and project teams. 

The successful candidate will be a hands-on drug designer: someone who can partner closely with medicinal chemists, structural biologists, biologists, and DMPK scientists to guide compound design from hit identification through lead optimization and candidate selection. They will also apply practical tools that improve decision-making, accelerate design-make-test-analyze cycles, and make computational and AI-driven methods accessible to bench chemists. 

The ideal candidate is a computational drug hunter who combines strong technical expertise with practical medicinal chemistry judgment. This person should not be an isolated modeler, but a true project partner who sits with chemistry teams, understands the design problem, proposes molecules, helps interpret data, and contributes tools that make the broader organization faster and smarter. 

This role is ideal for someone who has worked in a pharma or biotech computational chemistry group and wants to work with modern, AI-enabled computational methods while remaining directly involved in molecule design. 

What You'll Do

Computational Chemistry and Molecular Design 

Provide hands-on computational chemistry support to small-molecule discovery programs from target evaluation, hit identification, hit-to-lead, and lead optimization through candidate nomination. 

Apply structure-based and ligand-based design approaches to guide compound design, including docking, molecular dynamics, pharmacophore modeling, QSAR, scaffold hopping, virtual screening, FEP/free-energy methods, and multi-parameter optimization. 

Use structural biology data, including X-ray structures, cryo-EM structures, homology models, and AlphaFold-derived models, to generate actionable design hypotheses. 

Partner with the medicinal chemistry team to interpret SAR, optimize potency, selectivity, physicochemical properties, ADME/PK, developability, and synthetic feasibility. 

Contribute to computational design discussions with project teams and translate complex modeling results into clear, practical medicinal chemistry recommendations. 

Support portfolio prioritization by evaluating target tractability, ligandability, binding-site quality, chemical matter, and developability risks. 

Cheminformatics and Data Infrastructure 

Use and help improve chem and bioinformatics tools that support compound registration, structure-searching, SAR analysis, property visualization, compound triage, library design, and project decision-making. 

Apply tools for chemical data handling, including similarity and substructure searching, R-group analysis, matched molecular pairs, reaction enumeration, compound clustering, property prediction, and visualization. 

Work with internal or external engineering and data science teams to integrate chemical, biological, DMPK, structural, and assay data into usable project dashboards and design tools. 

Follow best practices for chemical data quality, assay data curation, compound annotation, metadata standards, and reproducible computational workflows. 

Use commercial and open-source computational tools, including platforms such as Schrödinger, MOE, CCDC tools, ChemAxon, KNIME, Pipeline Pilot, RDKit, DataWarrior, Spotfire, and related systems.

AI/ML and Digital Chemistry Tools 

Apply user-friendly AI/ML-enabled molecular design tools, including generative chemistry, predictive ADME/Tox models, property prediction, active learning, virtual screening, and decision-support systems. 

Help incorporate AI tools into the DMTA cycle, including compound prioritization, library design, synthetic route ideation, molecular-property prediction, and design hypothesis generation. 

Support AI literacy across chemistry and project teams by helping colleagues understand appropriate use, limitations, and interpretation of predictive models. 

Help develop workflows that allow medicinal chemists to use modeling and AI tools without requiring deep computational expertise. 

Collaboration and Continuous Improvement 

Contribute to the computational chemistry approach for projects and align it with discovery program needs. 

Serve as a subject-matter resource for computational chemistry, cheminformatics, AI-enabled design, and molecular modeling. 

Support collaborations with CROs, software vendors, academic groups, and computational chemistry consultants where appropriate. 

Represent computational chemistry in project team meetings and program discussions. 

Maintain awareness of emerging computational, AI, and cheminformatics technologies and recommend adoption where scientifically and operationally justified.

About Us

Work Hard/Play Hard. We believe time is our most valuable commodity, so we strive to create a culture that reflects this. We won’t drag you through unnecessary meetings or email you at 7 PM on a Saturday. When we're at work, we're there to get things done, and when we're off, we're really off. 🌴

Strong Communication. We like well-written documents over PowerPoints, OKRs over vague mission statements, and weekly one-on-ones over yearly reviews.

Writing First. We have a "writing-first" culture. We believe that clarity of writing reflects clarity of thinking and that the benefits of well-written documentation in a scientific environment are innumerable: democratization of ideation and decision-making, increased reproducibility, quicker scaling and onboarding, and better company-wide alignment, to name a few.

Growth. As an early-stage startup, we value scientists with an independent, can-do attitude. The more hats you can wear, the better. Our job as employers is to put you in positive feedback loops so you can grow in the direction of your choosing.
