Job description

Solarplaza is looking for an International Business Developer (32-40 hours per week)

About Us

At Solarplaza, we believe meaningful connections drive the energy transition. Through our international B2B conferences, market insights, and digital platforms, we bring together renewable energy professionals from around the world to share knowledge, build partnerships, and shape the future of solar and energy storage. Based in Rotterdam, our diverse team of 40+ colleagues from more than 15 nationalities is passionate about creating impactful experiences that help accelerate the global energy transition.

Join us as an International Business Developer

Are you an experienced Business Developer who thrives in an international environment where ownership, relationships, and commercial results go hand in hand?

At Solarplaza, we are looking for an International Business Developer to take ownership of sponsorship sales and commercial growth across our international B2B conferences in solar and energy storage.

This is a high-ownership role combining new business development, account management, and commercial strategy. You will work directly with senior decision-makers, industry leaders, sponsors, and partners across the global renewable energy sector.

What We’re Looking For

You spot the opportunity. You build the relationship. You make it happen.

We’re looking for a high-energy Business Developer who loves the thrill of opening doors, winning trust, and turning conversations into commercial results. Someone who takes ownership, thinks big, and wants to have a visible impact on a growing international business.

• You hunt for opportunities. You’re proactive, curious, and always looking for the next door to open.
• You know how to win. You’re commercially driven, target-focused, and have a track record of turning prospects into customers.
• You build relationships that last. You earn trust quickly, understand what matters to your customers, and aim to help them solve real problems through partnerships that create value for both sides.
• You own your number. Your pipeline, your accounts, your targets, your results. You take responsibility and make things happen.
• You think commercially. You understand the client, spot the opportunity, and create partnerships that deliver value for both sides.
• You thrive internationally. Different markets, cultures, and perspectives energize you rather than slow you down.

What Success Looks Like

Success in this role means making a direct and meaningful contribution to the growth of our international events and business:

• Consistently delivering against sponsorship and partnership revenue targets.
• Building and converting a strong pipeline of new business.
• Growing existing accounts and developing long-term partnerships.
• Building a strong network of senior decision-makers across the renewable energy sector.
• Identifying new commercial opportunities and turning them into tangible results.
• Maintaining a healthy, well-managed sales pipeline in Salesforce.

What You Bring

• 3+ years of experience in B2B sales, business development, sponsorship sales, or account management.
• A proven track record of owning commercial targets and delivering results.
• Experience managing the full sales cycle, from prospecting to closing.
• Strong relationship-building and negotiation skills.
• Confidence engaging senior decision-makers and industry stakeholders.
• A proactive and hands-on approach to business development.
• The ability to work independently, manage priorities, and take ownership.
• Excellent communication skills in English.
• Experience in renewable energy, events, or another international B2B environment is a strong plus.
• Experience with Salesforce or another CRM is a plus.
• Based within commuting distance of Rotterdam.
• Willingness to travel internationally for conferences and industry events.

Preferred Experience

• Experience selling sponsorships, partnerships, or B2B services.
• Existing network within solar, energy storage, or the broader renewable energy industry.
• Experience working with international clients and stakeholders.
• Additional languages.

What We Offer

• 28 days of paid leave per year (based on full-time employment).
• The salary range for this position is €3500 - €4900 gross per month, with the final offer determined based on relevant skills, professional experience, and qualifications.
• A performance-based bonus scheme linked to revenue targets, with the opportunity to earn up to one additional month’s salary per year.
• Initial 12-month contract with the intention to extend.
• Up to 20 remote working days per year (after 6 months).
• A €1,000 personal development budget per year (after 6 months).
• Extensive opportunities to grow your international network and expertise in the renewable energy industry.
• An open, respectful, and multicultural work environment.
• Access to a bike lease plan through Lease a Bike.
• Travel expense compensation through an NS-Business Card or mileage allowance for commuting distances between 10 km and 50 km (one way).
