What are the responsibilities and job description for the Applied Scientist position at Cartesian?
Cartesian is building wireless foundation models to map the indoor world at scale.
We are tackling one of the biggest unsolved problems in the $35-trillion global retail industry: inventory visibility within stores. Our first-of-its-kind inventory intelligence product is enabling unprecedented indoor positioning and insights to solve this problem for retailers, starting with international fashion brands.
Our founders are an MIT engineering professor and alum who invented the award-winning patented technologies underlying Cartesian. Since spinning out in 2023, we've bootstrapped to a deployed product, secured the highly selective SBIR grant from the U.S. National Science Foundation, and are generating revenue from paying customers.
We're now looking for a highly motivated, product-oriented Scientist to join our core R&D team at a pivotal moment in our growth. You'll have a direct impact on core algorithms, take ownership of new features, and shape the technical roadmap of a category-defining product. We move fast, care deeply about quality, and value people who take initiative and crave real-world impact.
You'll be joining us in-person in the heart of Kendall Square, Cambridge, next to MIT and the Charles River.
