Thrive Market is a membership-based online retailer that offers discounted, health- and sustainability-focused groceries, pantry staples, personal care, supplements, baby and pet products, and household essentials. The service personalizes product selection to customers' dietary needs and preferences (e. g. , organic, gluten-free, high-protein, low-sugar), emphasizes strict product standards (non-GMO, no artificial flavors/colors, no synthetic preservatives, etc. ), and provides scheduled delivery and repeat-order capabilities. Thrive Market also runs a social-impact component—sponsoring one-year memberships for people in need, accepting SNAP EBT, and donating healthy groceries and disaster relief funds.

• Build new ML systems from the ground up, close data gaps as they arise, and maintain and improve the existing ML pipeline • Read and implement ML papers on alternative model architectures, then run training experiments to benchmark results against current production models • Stand up and manage infrastructure, such as a Redis cluster, to support ML workloads • Weigh in on and help drive architecture decisions and statistical methodology alongside the broader engineering team • Help shape Thrive Market's long-term vision for search and discovery, informed by how large language models have changed what's possible to build • Present model results and roadmap, including business and revenue impact • Bridge hands-on MLOps execution with research-level thinking across infrastructure, experimentation, production, and business outcomes
