Customer Success Manager
About Cartesian
Cartesian is building spatial intelligence for indoor environments to drive operational efficiency. We’re tackling one of the biggest challenges in the $35T global retail industry: in-store inventory visibility. Our platform delivers accurate indoor positioning and actionable product location insights, helping retailers streamline operations, optimize workflows, and reduce inefficiencies. Leveraging wireless signals, we provide a uniquely scalable, infrastructure-free solution already deployed by international fashion brands.
Founded by an MIT engineering professor and alum behind the award-winning, patented core technologies, Cartesian spun out in 2023. Originally backed by the prestigious SBIR Award from the US National Science Foundation, we've bootstrapped to a live product that's now deployed in over a dozen countries and have been aggressively scaling in the market.
About the Role
We’re looking for a Customer Success Manager to help our retail customers successfully pilot, adopt, and grow with Cartesian. You’ll own the customer journey from demos to onboarding and implementation through long-term partnership, turning our technology into measurable improvements in store operations.
You’ll work directly with retail leaders, store teams, and technical stakeholders to understand their workflows, coordinate deployments, and help them get value from our platform. Internally, you’ll partner closely with Engineering and Business Operations to resolve issues, communicate customer needs, and build the processes that support our next stage of growth.
This is a hands-on individual contributor role with meaningful ownership. You should be equally comfortable leading a customer meeting, visiting a store to understand a workflow, and following through on the details that keep a deployment moving.
Location: In-person in Kendall Square, Cambridge (or as otherwise specified).
