Hamburger Energiewerke is Hamburg's 100%-municipal utility provider managing the city's energy supply across thermal, renewable, and emerging hydrogen sectors. The technical stack is heavily SAP-centric (BTP, S/4HANA, ECC, HANA, Integration Suite) with secondary depth in enterprise identity and data tools (Azure AD, SAML, Oracle, PostgreSQL), reflecting a large-scale utility managing grid operations and billing at enterprise maturity. Active hiring is engineering-focused (20 of 33 roles), with a Technical Managing Director vacancy signaling leadership investment in IT transformation—critical given the stated pain point of legacy SAP modernization alongside a concurrent hydrogen electrolyzer deployment project.
