Internship Graduate Machine Learning Jobs in Williamstown, MA

About the position This is the role for someone straight out of university who wants to build a career in B2B marketing at a high-growth tech company and learn faster in two years than most people do in five.
 
Pentaleap is one of the most exciting companies in advertising technology right now having won leading enterprise customers such as Macy’s, The Home Depot, CVS Health and many more. We’re the retail media infrastructure powering the next generation of sponsored ads for retailers and marketplaces working with some of the biggest names in retail in a category that’s growing faster than almost anything else in advertising.
 
You’ll join as an Growth & Marketing Manager reporting directly to our CMO and working closely with the wider leadership team. From day one, you’ll be deeply involved in campaigns, events, content, and go-to-market execution while learning how a modern B2B marketing engine operates at scale.
 
As the company grows, the role will grow with you. The expectation is not that you already know everything, but that you learn quickly, take ownership early, and develop into a future marketing leader inside the company.
This role is built for graduates who want steep learning curves and early responsibility. Over time, you’ll take ownership of larger initiatives, run projects independently, and grow into a more senior role within the company.
You’ll work closely with experienced operators, get exposure to executive-level decision-making, and develop a deep understanding of how high-growth B2B technology companies scale. Your responsibilities You’ll support the execution of Pentaleap’s marketing activities across campaigns, events, content, and social media. This is a highly hands-on role designed for someone who wants exposure to every part of modern B2B marketing instead of being limited to one narrow area.
You’ll work directly with experienced operators across marketing, sales, and leadership while taking ownership of projects early on.
