Business Development Manager Water Sector

As climate change and pollution increasingly threaten our limited freshwater resources, protecting groundwater has never been more urgent. With around half of our drinking water coming from groundwater, iFLUX helps enable its sustainable management through innovative, service-oriented solutions.

To support our growth, we are looking for a Business Development Manager who actively explores the markets, positions our service-oriented solutions commercially, and helps build a healthy growth strategy for the future.

Do you identify with our values of keeping things down-to-earth and actionable, embracing dynamic change, and doing good for people and water? Then join our team!

How does your role look like?

In this role, you will research, develop, and enter new markets where our solutions can make a difference.

You put our services on the map with the right target groups.

You convince through insight, listen to needs, and know how to turn a conversation into a concrete proposal. You follow the entire process – from first contact to deal – and remain a sparring partner for our clients afterwards.

Specifically, this means:

• The successful candidate will identify and develop new markets for our service-oriented solutions.
• Conduct outreach, networking, and lead generation within a B2B and B2G context.
• Guide the entire sales process: from first contact to quotation, proposal and negotiation.
• Research and evaluate product-market fit, and translate market insights into concrete proposals.
• Help translate our value proposition to sector-specific needs and contribute to developing our commercial strategy.
• Work in an environment where much is happening, bringing focus without losing sight of the goal.
