Opinum Is Hiring!

Full Stack Azure Backend

About

At Opinum, we empower energy and water companies to operate with greater agility, financial control, and customer-centricity in a rapidly evolving utility landscape.

Our cloud-native SaaS platform enables the design of innovative products, implementation of dynamic pricing, and execution of real-time financial transactions , turning granular operational data into actionable insights and capabilities.

Specifically built for the needs of energy and water providers, Opinum supports flexible product configuration, real-time billing and next-generation data integration.

Utilities use Opinum to respond faster to regulatory and market changes, manage margins across the full product lifecycle, reduce dependency on custom development or consulting-heavy solutions and strengthen collaboration across customers, partners, and flexibility markets.

Our mission is to equip energy and water companies with the tools they need to create long-term value, both for their customers and for the energy system as a whole.

Opinum integrates easily with existing IT and (behind the) meter infrastructures, offering scalable, cloud-native capabilities with a strong focus on usability and extensibility.

Our vision is an energy and water sector that’s adaptive, customer-driven, and prepared to lead, not follow, the transition ahead.
