Joulz België - Asset Portfolio Manager - Belgium

This is a role for Joulz - Belgium.

Are you looking for a place where trust comes first, where there is room to grow and where your contribution makes a visible difference? As Asset Portfolio Manager at Joulz Belgium you get the opportunity to help manage and optimise a portfolio of more than 100 MWp of solar assets and to grow into a broad business role with increasing responsibility and impact.

This is Joulz

Every day at Joulz, we work on reliable and future-proof energy solutions for organisations that simply have to keep running. In a sector that never stands still, we make complexity clear and we take responsibility: for our customers and for each other.

We develop, build, finance and operate tailored, integrated energy solutions. Today we manage a portfolio of more than 100 MWp of solar assets, and we keep expanding.

What defines working at Joulz?

A combination of craftsmanship, trust and a start-up mentality. You get the space to take initiative, and to keep developing yourself. We work together in an informal, professional atmosphere where involvement is a given and where everyone's contribution counts. As a small and growing team, we offer a hands-on environment where your contribution has visible impact from day one.

In this role:

• You help manage and optimise a portfolio of more than 100 MWp of solar assets, working across operational performance, customer relationships, financial follow-up and process improvement

• You monitor operational and financial asset performance and identify deviations, risks and improvement opportunities

• You contribute to better processes, tools and governance, so portfolio management becomes more scalable and consistent

• Depending on your experience, you progressively take ownership of an assigned portfolio

This is what you'll pick up

• You turn operational and financial data into clear priorities and documented follow-up

• You build strong customer and partner relationships through clear, proactive communication

• You coordinate incidents, priorities and follow-up with customers, maintenance partners and internal teams

• You identify opportunities to strengthen customer value, including battery storage and energy management solutions

Who you'll work with (and why that works)

The colleagues around you and how you get results together.

You report to the Head of Portfolio & Strategic Partnerships and work closely with customers, maintenance partners, suppliers and colleagues across the Belgian and Dutch teams. At Joulz we believe in doing it together, helping each other out and communicating clearly.

What you can expect from us

Terms, freedom and development opportunities.

You make an impact, and we reward you with:

• A competitive compensation package aligned with your experience

• Structured and accountable, with the discipline to prioritise and follow actions through to completion

• Analytical and financially literate, confident working with operational data and Excel

• Clear communication with customers, suppliers and internal stakeholders

• Hands-on and pragmatic, while continuously looking for smarter and more scalable ways of working

• Experience in energy, renewable energy or technical asset management is an advantage, and is expected for more experienced applicants

• Familiarity with Microsoft 365 and AI-enabled workflows is an advantage
