About The Position

Jane Technologies is an MIT-founded eCommerce company in the cannabis industry experiencing rapid growth. We believe in cannabis's ability to bring well-being, health, and love to the world, and our mission is to bring confidence to the online cannabis shopping experience. Our platform connects consumers with local dispensaries and brands, creating a seamless shopping experience and delivering industry-leading insights to our retail, brand, and integration partners. Dispensaries use Jane to sell cannabis products compliantly and efficiently. Brands plug into the platform to reach shoppers via personalized sponsored content. Shoppers engage with Janeâ€™s online menus to make purchasing decisions via rich product content and verified reviews. These services come together to form a tightly integrated ecosystem - creating diversified revenue streams for Jane and a win-win-win equation for the industry. We are a small close-knit team of highly technical engineers with diverse backgrounds. We have a strong engineering culture, which values lean development, data-driven practices. We are rapidly growing 20% month over month and are always tackling challenging and interesting technical problems. We are building a robust, feature-rich, and easy-to-use advertising platform that improves the marketing efficiency for brands and dispensaries. Weâ€™re AI-enabled, not AI-driven. AI tools (Claude, AI-assisted reviews, generated plans) are part of how we work, but the engineering judgement behind every decision is human.
