About iwell

At iwell, our mission is to strengthen energy security across Europe. We empower businesses to become more energy independent in the face of increasing regulations, volatile energy prices, and growing grid instability. In today's dynamic energy landscape, resilience is essential—and we help our clients take control and stay ahead.

We provide advanced energy management solutions that give businesses full command over their energy systems. Our proprietary Energy Management System (EMS) and modular Battery Energy Storage Systems (BESS) are designed to maximize profitability through sustainable operations, helping businesses future-proof their operations.

iwell is a rapidly growing international team of driven, skilled professionals. From engineers and software developers to creative strategists and customer-centric business developers, we're united by a shared commitment to driving positive change. We're always on the lookout for passionate individuals ready to make a real impact.

Job Summary

Over the past eight years, iwell has been dedicated to optimizing behind-the-meter energy flows by integrating our proprietary Energy Management System (EMS) software with our Battery Energy Storage System (BESS) hardware. By intelligently managing energy production and consumption—including solar PV, EV charging, and battery storage—we enable businesses to balance their energy profiles and reduce peak demand. Where applicable, we unlock additional revenue potential through participation in wholesale and balancing energy markets, tailored to each individual site.

iwell has built a broad and diverse client portfolio, spanning various use cases, battery configurations, and geographical locations. Each site presents its own unique set of constraints and opportunities. Through localized optimization and targeted energy trading, we maximize the value of each installation. Our next strategic step is the development of the iwell Virtual Power Plant (VPP): a platform for aggregating and monetizing the flexibility of our entire battery portfolio.

We thrive on the complexity of combining client-specific revenue models with ever-changing market dynamics and site-specific constraints. It's this challenge—balancing cost reduction, revenue generation, and sustainability targets—that drives us. Ultimately, our goal is to deliver solutions that minimize carbon emissions while maximizing market performance.

As a Business Case Developer at iwell, you are responsible for developing and validating investable business cases for our clients. You translate complex energy concepts into clear, actionable proposals. Your strength lies in combining technical insight with commercial strategy to design innovative, high-impact solutions tailored to each client's energy profile and objectives.

Working closely with our sales teams, you are not directly responsible for closing deals—but you are essential in enabling them. Your ability to communicate technical and financial complexity in plain, compelling language sets you apart.

To lead these efforts, we are seeking an experienced Business Case Developer with deep expertise in local energy optimization and energy trading. You bring hands-on experience from the Belgian energy markets and a strong understanding of how to bridge client needs with dynamic energy opportunities.
