Experimentation Scientist
Uncover actionable insights through rigorous A/B testing and statistical analysis.
What is an Experimentation Scientist?
Experimentation Scientists design, execute, and analyze A/B tests and multivariate experiments to improve products and user experiences. They work closely with product managers and engineers to translate hypotheses into testable experiments, ensuring statistical validity and deriving meaningful conclusions.
You split time between designing experiments, programming analysis pipelines, and running field campaigns. Mornings may be data cleaning and code runs; midday brings meetings to set priorities and team roles; afternoons are for supervising technicians, preparing technical reports, or visiting aquatic and terrestrial sites to collect biological samples. Grant writing and liaison work with agencies punctuate project cycles.
