From Cartesian Systems's posting. “We” and “our” refer to the employer.
Micro-Intern: Software Engineer (IAP - Alumni Host)
Location
: On-site; Boston/Cambridge, MA;
Full-Time; January 4, 2027 - January 29, 2027
Compensation
: $20-25/hr
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 are scaling up our platform and developing new features to meet product demand.
We are looking for a motivated software engineering intern to help us integrate with new customers, improve our core platform, and expand our product capabilities. We are seeking individuals who want to see how to design and develop new technology in a startup environment. You will work alongside senior engineers and ship code to real customers.
This role is on-site, and our office is right in Kendall Square by the Red Line stop.
The internship will be full-time. IAP is less than a month, and in order to maximize the value of the internship for you and Cartesian, it requires a full-time focus. If you have other commitments over IAP (e.g. clubs or classes), it probably won’t be a good fit.
High Growth
: You're curious and learn fast. You'd rather dig into something unfamiliar than stay in your comfort zone.
Given a task, you break it down with minimal oversight and make sure it gets done – even when it's ambiguous, or the last bit gets messy.
Low Ego
: You don’t know everything. You want the best ideas to win. Nothing is below you.
You write clean, working code without heavy hand-holding, and you can explain the "why" behind your choices, not just show the result. You’ve worked in large codebases on a team before.
Why Now?
We’re a fast-moving MIT startup at an important inflection point for our product growth and direction. We are building a talent-dense team of engineers and applied researchers to solve hard, high-impact problems in retail operations.
The IAP internship is a great way to see the inner workings of a company going from an initial product to a broadly scaled platform across many customers. You will be able to shape real product and platform decisions.
: Answer the logistical and interest questions.
Interview (60 minutes)
: Show us something cool you’ve built. Explain your decisions and what you learned. Ask any questions about the role or company.
Offer
Note: We’ve received a large number of applications for this internship in the past. We try our best to review everyone, but sometimes you may not hear back.
