MBA Summer Intern

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. By fusing wireless signals and mobile computer vision, we provide a uniquely scalable, infrastructure‑free solution already deployed by international fashion brands.

Founded by an MIT engineering professor and alumni behind award‑winning, patented core technologies, Cartesian spun out in 2023. Originally backed by a U.S. National Science Foundation SBIR Award, we’ve bootstrapped to a live product now deployed in multiple countries and are scaling aggressively.

We are looking for an MBA Summer Intern to join Cartesian at a pivotal moment in our growth. This is a hands‑on, impact‑driven role. We value relevant experience, but what matters most is your ability to drive outcomes by learning quickly, thinking analytically, and navigating ambiguity.

You will work closely with the business team on key initiatives in startup operations and strategy, like customer success, market research, marketing, fundraising, go‑to‑market strategy, and internal operations. We move quickly, value ownership, and expect high‑quality work. You will have meaningful responsibility from day one and the opportunity to influence decisions and how our product evolves in the real world.

In‑person in Kendall Square, Cambridge.

• Own and drive a project in a critical business area such as early customer success, product requirement definition, market research for emerging products, and operational scaling, from problem definition through execution.
• Conduct market, competitive, and customer research; synthesize insights into clear recommendations; and support strategic decision‑making with founders and the business team.
• Support core business operations such as partnerships, inbound and outbound inquiries, and coordination across go‑to‑market and operational initiatives.
• Help design, improve, or automate business processes/systems that support continuous operations of the company.

• Be in the process of obtaining an MBA (or a recent alum)
• 3+ years of experience in consulting, market research, fashion retail, or startups.
• Strong problem‑solving skills and comfort working in ambiguous, fast‑moving environments
• Ability to design, execute, and learn from structured analyses or iterative initiatives
• Experience creating clear, maintainable, high‑quality work (presentations, analyses)
• Strong collaboration and communication skills
• Curiosity, ownership, and a bias toward action and real‑world impact

• Startup or early‑stage company experience
• Experience working closely with cross‑functional teams
• Fluent in Spanish

• Work on hard, real‑world problems with immediate and visible impact
• Join a small team with significant ownership and autonomy
• Collaborative, thoughtful, low‑ego culture focused on learning and execution

We know that no one checks every box—and we don’t expect you to. If this role sounds exciting to you, and you think you could contribute to Cartesian’s mission, we encourage you to apply even if your experience doesn’t perfectly match the description. We care deeply about people who are curious, thoughtful, and motivated to learn, and we believe strong teams are built from a diversity of backgrounds, experiences, and perspectives.
