Front End Software Engineering (React.js) Co-op - 2026

Tamr offers an AI-native Master Data Management (MDM) platform designed to help enterprises create unified, accurate records across vast, complex data ecosystems. Tamr accelerates the discovery, enrichment, and maintenance of golden records — clean, trusted, and continuously updated profiles — that enable informed decision-making and improved operational efficiency. With a co-founding team led by Andy Palmer (founding CEO of Vertica) and Mike Stonebraker (Turing Award winner) and backed by top-tier investors such as NEA and Google Ventures, Tamr transforms how companies get value from their data.

We are looking for an intern to join our core engineering team in Harvard Square (Cambridge), one of the most important technical hubs in the world! Our team is a close-knit group of about 40 professionals who are always willing to teach and eager to learn. We’ve created a collaborative, supportive, fun culture while doing serious work. 

With such a small team, every member needs to contribute meaningfully and impact the business. So, when you join, we will work with you to find the project you want to work on—one that you're excited to finish and that we're excited to have. 

As an intern, you'll join a team of 4 or 5 people. You will be treated like a regular employee. You'll have a manager who will mentor you in your professional development and a tech lead who will support you with scheduling, architecture, and coding. You will design, break down, and own stories for every sprint. Your code will be held to the same standard expected of every engineer.  

The applicant must be local to the Boston/Cambridge area. Tamr is unable to provide relocation for co-ops and interns.

Applicants must be currently pursuing either a Bachelor's or Master's degree in Computer Science, Information Systems, or a technically related field, and should be available for the internship from January 2026 to June 2026. This position is based out of our office in Cambridge, MA.
