Description du poste

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.

Our Values

Open-minded: We welcome diverse perspectives, stay curious about each other’s realities, and create bridges between teams and locations. Open-mindedness at Opinum means staying connected, inclusive, and always learning from others.

Nimble: We value speed with thoughtfulness. Being nimble means learning fast, adapting when needed, and building without overcomplicating — while keeping an eye on innovation and continuous improvement.

Build Trust: We earn trust by being honest, human, and reliable — with customers and each other. It’s about showing up authentically, listening, and doing what we say, consistently and transparently.

Impactful: We aim to create meaningful, measurable, and lasting positive outcomes — for our customers, our company, and the world around us. We consider the environmental and societal impact of our work and make intentional, responsible choices.

Authenticity: We communicate with honesty, humility, and clarity. We share progress, acknowledge mistakes, and offer feedback in a way that is constructive and respectful. Being authentic means being consistent in what we say and do.
