rhenag is a 150-year-old German utility operator (gas, electricity, water, heating) that has evolved into a dual-model business: direct supply to end customers in the Rhine-Sieg region, plus a B2B software and consulting arm serving 200+ municipal utilities nationwide. The hiring surge (19 roles in 30 days, accelerating) is concentrated in legal, consulting, and support — not engineering — and projects center on process digitization, billing systems, and LMS rollout, suggesting internal modernization and training infrastructure are the immediate growth drivers.
