About the job

As part of our team, you will help to accelerate and optimize our progress in agentic AI methods for biological and clinical data curation and analysis. In this role, you will be an integral part of our multidisciplinary teams building the computational platforms that will enable Altos to achieve its mission. You will collaborate with biomedical research experts as well as other machine learning scientists and engineers across the Institute of Computation to contribute to the Altos research and translation ecosystem, focusing on designing and building state-of-the-art agentic AI systems and workflows that tackle biological questions, accelerate clinical data analysis, and aid in the discovery of novel interventions for aging and disease.

Responsibilities

Design and develop agentic AI workflows for biological and clinical data curation tasks

Research and implement advanced context engineering techniques (RAG, agentic RAG, graph RAG) tailored to biomedical data

Develop and optimize prompts and agent architectures for reliability, accuracy, and scientific rigor

Build LLM-based tool-use systems and integrations relevant to bioinformatics and clinical R&D pipelines

Collaborate with bioinformatics scientists, clinical researchers, and domain experts to identify automation opportunities and translate them into agentic solutions

Evaluate and benchmark agentic systems, establishing rigorous metrics for performance and correctness in scientific contexts

Stay current with the rapidly evolving landscape of agentic AI methods and contribute to internal best practices

Qualifications

Minimum

PhD in Computer Science, Machine Learning, Bioinformatics, or a related field

Demonstrated experience developing agentic AI systems, including LLM-based tool use, prompt engineering, and context engineering techniques

Strong foundation in machine learning principles and their application to real-world problems

Strong background in bioinformatics, computational biology, or clinical R&D

Familiarity with MCP server development and agent skill creation

Very strong programming skills in Python, with experience writing production-quality, well-documented code

Strong track record of published peer-reviewed research in AI/ML and/or computational biology

Preferred

Experience with AWS services (S3, Bedrock, Lambda) in the context of AI/ML workflows

Experience with clinical trial data, regulatory data curation, or biomedical ontologies (e.g., CDISC, SNOMED, MedDRA)

Track record working with NGS data (e.g., RNA-seq, ATAC-seq, DNA methylation) or other biological data modalities

Experience designing evaluation frameworks and benchmarks for agentic AI systems

Familiarity with knowledge graph construction and graph-based retrieval methods
