Design and construct evaluation benchmarks to measure model capabilities on biology tasks including figure interpretation, bioinformatics, protocol reasoning, and literature synthesis.
Collaborate closely with product and design teams to scope, prototype, and release features for life sciences users.
Partner with external biotech, pharma, and academic users to understand real-world workflows and transform feedback into product enhancements.
Build and maintain the engineering infrastructure supporting the biology product surface, including tool scaffolding, data pipelines, and evaluation harnesses.
Translate deep biological domain knowledge into clear product requirements and evaluation criteria to guide model improvement.
Requirements
Experience applying machine learning and software engineering to biological problems such as computational biology, bioinformatics, protein machine learning, or genomics.
Professional background in drug discovery or development within a biotech or pharmaceutical company, or fundamental research experience in an academic setting.
Strong software engineering skills with the ability to write production-quality Python, navigate large codebases, and manage infrastructure end-to-end.
Hands-on experience with training or fine-tuning machine learning models, including large language models, protein language models, or other deep learning architectures.
Demonstrated track record of shipping computational tools or pipelines utilized by biologists.
Comfort with navigating ambiguity and defining problems within a rapidly evolving research environment.
Ability to work independently while collaborating closely with research, product, and domain-expert teams.
Results-oriented mindset with a strong bias for rapid iteration and measurable impact.
Nice to Have
Five plus years of experience applying machine learning and software engineering to biological problems.
Ph.D. in computational biology, bioinformatics, bioengineering, computer science, or a related quantitative field, or equivalent industry experience.
Experience with large language model post-training methods such as reinforcement learning from human feedback, reinforcement learning from verifiable rewards, supervised fine-tuning data curation, or evaluation-driven development.
Direct experience with therapeutic discovery pipelines, including target identification, lead optimization, ADMET modeling, or clinical data analysis.
Familiarity with bioinformatics tooling and pipelines such as sequence analysis, structure prediction, single-cell analysis, and variant calling.
Experience building agentic systems or tool-use environments.
Published research in machine learning for biology or open-source contributions to computational tools.
Fluency with biological databases like UniProt, PDB, Ensembl, and NCBI, along with the ability to reason about schemas and failure modes.
