Role description

This role is located in Budapest, Hungary - We are a hybrid work environment and are in the office 3+ days/per week.
Tulip brings modern technology and AI into manufacturing - a sector that drives 15% of global GDP and employs one in seven workers, yet remains among the least digitized. More than a decade ago we created the category to close that gap: AI-native software that puts cutting-edge tools directly in the hands of the people who build things. Because we are human-centered and tech-obsessed, we are building a future of work where human ingenuity is nourished and amplified with the latest technology.

It's a rare moment to join. In January 2026 we became one of Boston's few new AI unicorns, reaching a $1.3B valuation at Series D, and we're growing double digits in revenue year over year. The world's best manufacturers run on Tulip - turning inventory 10x faster, releasing gene therapies in hours instead of weeks, and training master craftspeople to forge engagement rings 5x more rapidly. Headquartered in Somerville, MA with offices in Germany, Hungary, Singapore, Japan, and Israel, we've been named a World Economic Forum Global Innovator, a Gartner leader, and one of Built In Boston's "Best Places to Work."

Nice to Have

  • Experience with machine tools and/or the manufacturing industry
