Proficiency in Figma is required. * You're hyper-analytical: you test your hypotheses rigorously and let data guide your priorities. * You're passionate about B2C mobile apps and have a track record of shipping meaningful features or products. * You're highly driven, autonomous, and results-oriented. * You're fluent in English (French is a plus).
