Head of Data Science

Company Description

OncoHost is a technology-driven leader in precision medicine, advancing patient outcomes through innovative, clinically validated diagnostic solutions. The company’s proprietary PROphet® platform leverages high-dimensional proteomic pattern analysis to support immunotherapy decision-making for patients with non-small cell lung cancer (NSCLC) using a single blood sample.

Validated in a large-scale, global clinical trial spanning more than 40 sites and 1,700 patients, PROphet® enables physicians to predict treatment efficacy, assess toxicity risk, and uncover biological mechanisms of resistance — supporting more informed, data-driven immuno-oncology decisions.

Role Overview

The Head of Data Science will lead OncoHost’s data science strategy, driving the development of predictive, biologically grounded AI models that support clinical decision-making. This role combines scientific leadership, hands-on technical expertise, and cross-functional influence.

Reporting to the CTO, this leader will shape the long-term data science roadmap, build and mentor a high-performing team, and ensure scientific rigor across all computational activities.
