Customer Success Manager

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.

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).

Own customer relationships

• Lead demos and pilots with prospective customers, and drive the conversion from pilot to rollout. 
• Establish clear success plans with customer goals, milestones, stakeholders, and measurable outcomes.

• Serve as the primary point of contact for assigned customers, building relationships across store operations, corporate leadership, and technical teams.

Lead onboarding and implementation

• Work with customer teams to understand store workflows and incorporate Cartesian into day-to-day operations.
• Coordinate with internal technical teams to resolve implementation challenges and keep customers informed.

Drive adoption and customer outcomes

• Partner with the business team on renewals, additional store deployments, and expansion opportunities.

Build a scalable customer success function

• Develop onboarding materials, training resources, playbooks, and repeatable processes.
• Bring structured customer feedback to Engineering to inform product improvements.
• Track customer health, surface risks, and maintain clear documentation of commitments and next steps.

• Experience managing enterprise customer relationships and coordinating implementations with multiple stakeholders.
• Strong project management skills, with the ability to manage competing priorities and follow through on commitments.
• Technical fluency and curiosity: you can learn a complex product, investigate issues, and communicate clearly with technical and nontechnical audiences.
• Strong communication and presentation skills, including the ability to navigate difficult conversations and align stakeholders.
• A practical, proactive approach to solving problems and comfort working in an early-stage company.
• Ability to work in person in Cambridge, MA, and travel to customer locations, including internationally, as needed.

• Experience working with enterprise retailers, store operations, inventory management, or supply chain technology.
• Familiarity with RFID, indoor positioning, computer vision, or products that combine software and physical devices.
• Experience supporting international customers or deployments across multiple locations.
• Experience building customer success processes at a growing startup.

• Own customer relationships and see the direct impact of your work in real stores.
