Telecommunications Montabaur, Rheinland-Pfalz 1,001–5,000 employees Public Company

1&1 operates Germany's largest fiber network (50,000+ km) and is building a modern 5G infrastructure using open-RAN technology. The tech stack reveals a traditional telecom operations profile—SQL, Power BI, Jira, ServiceNow—paired with emerging AI tooling (ChatGPT, Midjourney) and creative software (Adobe, Figma). Hiring velocity is decelerating overall, but the intern-heavy pipeline (23 of 48 active roles) and concentrated marketing hires (10 roles) suggest focus on customer acquisition and campaign execution rather than platform scaling.
