Technical Support Specialist (m/w/d)

Job Description

At sonnen, we're driven by a clear goal: creating a future powered by clean, affordable energy for everyone. That's why we make our customers independent - not only from fossil fuels, but also from rising electricity costs.

The key to this independence is our intelligent, all-in-one energy system. It combines solar panels, battery storage, energy tariffs, and wallboxes - all developed and manufactured in Germany.

As the first and only provider in Germany, we also connect thousands of home batteries into one shared network: the sonnenVPP, our industry-leading virtual power plant.

In short: every day, we're working to shape the energy future. And we'd be thrilled to have you join us!

To strengthen our international customer service team, we're looking for a Technical Support Specialist (m/w/d) in the greater Hasselt (Limburg) area, who will focus on supporting our Premium Partners in Belgium and the Netherlands.

What you'll do to help drive the energy transition

• Provide expert technical support to our international partners - with a strong focus on Belgium and the Netherlands - via phone, chat, and email.
• Handle and document all partner inquiries related to our battery storage systems and chargers using Salesforce.
• Diagnose technical issues remotely, plan on-site service assignments, and coordinate fault clearance and maintenance activities.
• Ensure high partner satisfaction through efficient, cost-effective, and solution-oriented case handling.
• Deliver technical trainings and guidance to sonnen partners, helping them provide the best possible service to end customers.
• Monitor local regulatory developments to ensure product compliance, and communicate relevant updates or improvement needs to the team lead.
• Meet regularly with our Premium Partners in Belgium and the Netherlands to strengthen cooperation and discuss service-related topics on-site.

What you'll need on that journey

• A completed technical apprenticeship or degree (e.g., electrical engineering, energy systems, or a related field).
• At least 1 year of experience in technical customer support - ideally within the solar or energy storage industry.
• A structured and analytical mindset with strong problem-solving skills and attention to detail.
• Excellent communication skills - empathetic, professional, and confident when guiding partners through technical challenges.
• Fluency in Flemish and English (spoken and written); additional languages such as French, Dutch, Spanish, Italian, or German are a plus.
• Solid IT proficiency, including Microsoft Office and CRM systems (preferably Salesforce).
• A strong customer and service orientation combined with a collaborative, team-driven attitude.

What you can expect at sonnen:

• An atmosphere of openness, tolerance and mutual respect, where innovation is expected and encouraged.
• 30-32 days annual vacation with increasing team membership.
• Leasing of company (e-)bikes with up to 40% discount.
• Flexible working hours and option working mobile.
• Use of sports memberships (EGYM Wellpass, only €29.75/month) and discounts for other services and products.
• Employee discount on our electricity tariff.
• Regular team and company events.
• We love dogs! You too? Feel free to bring your fellow friend to our offices.

You feel we are a match? Apply now and help us to shape the energy transition together. We look forward to welcoming you to #teamsonnen!
