About the Role Join a fast-moving AI and machine learning team building data-driven products in a startup environment. This role is suited to technically strong, quantitatively minded builders; a previous data science title is not required. What You'll Do • Build and ship practical machine learning and data science solutions in an early-stage, zero-to-one environment. • Use agentic AI coding tools as part of your daily development workflow. • Work with ambiguous data and contribute to production-focused technical work across the team. • Help the team maintain a high pace of execution in an intense startup setting. What We're Looking For • Five or more years of relevant technical experience, with an engineering or other strong technical background. • Strong quantitative foundations, such as a rigorous quantitative degree, advanced mathematics training, or equivalent demonstrated ability. • Daily hands-on use of agentic AI coding tools such as Claude Code, Cursor, or similar. • Experience as an early hire at a startup, ideally within the first 15 employees, and evidence of building in a zero-to-one environment. • Comfort operating at a demanding pace and working through ambiguous problems. • Retail or fresh produce experience is not required; the role is within AI and machine learning.
