phpList is the world's leading Open Source email newsletter and marketing solution, used in 97 countries by 30,000 customers. Email marketing is an extremely competitive field: we combine 15 years of experience with the most powerful Open Source components and a European base of operations. We're on a mission to make marketing open and transparent: our products are shared with the community under copyleft licenses.

Processing and monitoring millions of messages per-client, per-day requires stable, high-performance code, with sophisticated monitoring.

Jobs at phpList expose Open Source professionals to all these challenges and more within a supportive environment designed to grow skills and engagement.
