• Develop the agentic research vertical at PostEra using agentic systems to automate development of mechanistic models for biochemical and physiological processes • Analyse biological data for target validation and use models to drive drug discovery decisions • Develop machine learning methods that adapt to new drug discovery problems from limited labeled data • Build molecular and tabular in-context learning systems and foundation models from proprietary multimodal data • Determine relevant prior examples and tasks, quantify when transfer is helpful or harmful, and provide reliable predictions under distribution shift • Define tasks, construct datasets and evaluation episodes, develop baselines, train and scale models, perform rigorous ablations, and translate successful methods into capabilities used by scientists • Develop and benchmark agentic systems for quantitative biological and physiological models • Independently identify, formulate, and lead research projects involving in-context learning, agentic systems, few-shot adaptation, tabular foundation models, and molecular machine learning • Design and train models adapting to new assays, endpoints, targets, or chemical series • Rigorously compare approaches against strong baselines and curate bias-sensitive test cases • Collaborate with scientists on potency modeling, ADME prediction, selectivity, lead optimization, and early clinical study design • Develop efficient training and data pipelines and scale models across molecular and tabular tasks • Produce readable, reproducible research code; track experiments; contribute to code review, documentation, and shared modeling infrastructure • Publish results in leading machine learning, medicinal chemistry, or computational biology venues and represent PostEra to the scientific community
• PhD degree in machine learning, or STEM research involving the development of novel machine learning approaches • Track record of high-quality research, such as publications and open-source contributions • Strong research or engineering experience in modern machine learning, deep learning, or statistical modeling, backed by understanding of the theory behind machine learning algorithms • Demonstrated expertise in at least one relevant area: agentic workflows for science, machine learning approaches to bioinformatics and clinical data modelling, in-context learning, tabular learning, few-shot learning • Hands-on experience training, debugging, and evaluating ML models in Python using frameworks such as PyTorch or JAX • Ability to independently translate ambiguous scientific or technical problems into well-defined ML projects, including datasets, task definitions, baselines, metrics, and validation schemes • Ability to design careful experiments, benchmarks, and ablations that distinguish improvements from biases, and understand which aspects of the model led to the improvements • Comfort working in a startup environment where priorities evolve, data is imperfect, and high-quality judgment matters as much as raw model complexity • Prior drug discovery experience is not required • Nice-to-have: experience training tabular foundation models, particularly for sparse, heterogeneous, small-data, or high-missingness settings • Nice-to-have: developing molecular in-context learning systems or adapting general-purpose in-context models to molecular or scientific data • Nice-to-have: large model training, including 1B+ parameter models, distributed training, sharding, data parallelism, model parallelism, and large-scale data pipelines • Nice-to-have: development of AI “co-scientist” systems for physical or biological problems • Nice-to-have: hands-on experience modelling biological, biochemical or clinical data using machine learning approaches • Nice-to-have: moving research models into production scientific software or computational workflows
• Equity: 0.05 - 0.1% • Proportional compensation • Internal recognition • Meaningful promotions
