Technical Support Expert - DC Charging BE

Smappee · Harelbeke, Belgium (Hybrid) · Full-time · Posted 2026-08-31

Workplace: hybrid

Department: Customer Service

Description

Smappee (Smart Appliance for Energy Efficiency) helps businesses and individuals take control of their energy consumption. Through innovative energy management and EV charging solutions, we make energy efficiency accessible, helping reduce costs and contributing to a more sustainable future.

Why is an EV requesting 150 kW, but the charger is only delivering 60 kW?

The answer isn't always visible in one error message or one dashboard.

It could be related to the charger, the vehicle, available power, temperature, configuration, communication or another part of the charging ecosystem. Finding the answer means bringing different pieces of technical information together and understanding what the data is telling you.

If that sounds like the kind of puzzle you enjoy solving, we'd like to meet you.

To strengthen our Customer Service team at Smappee, we're looking for a Technical Support Expert – DC Charging with a strong analytical mindset and an interest in DC fast charging.

What can you expect?

You'll provide technical support to our certified installers and partners through phone, email, and our ticketing system, with a particular focus on technically complex EV charging cases.

You will:

• Provide technical support to installers and partners on Smappee EV charging solutions via phone, email and ticketing.
• Develop in-depth expertise in Smappee's DC charging solutions and act as a specialist for DC-related troubleshooting.
• Investigate charging performance and behaviour by analysing data from multiple systems, dashboards and technical sources.
• Diagnose complex issues by evaluating logs, measurements, configurations, communication flows, energy availability and vehicle interactions.
• Guide installers through troubleshooting processes and clearly communicate findings and recommended actions.
• Resolve technical cases independently where possible, escalate complex issues when needed, and document analyses in a structured manner.
• Collaborate with Customer Service, Sales Engineers and R&D to identify recurring issues, contribute to knowledge sharing, and continuously improve diagnostics and support proces
• Go onsite when necessary to help resolve a technical issue

Requirements

What do you bring?

We don't expect you to know about the Smappee ecosystem before you join. We are looking for someone who combines a technical foundation with a strong analytical mindset.

You may come from EV charging, electrical engineering, electromechanics, field service, industrial technology, technical support or another technical environment.

Ideally: 

• You have a technical degree or equivalent experience in electrical engineering, electromechanics, electronics, automotive technology or a related field.
• Strong understanding of electrical concepts and the ability to work with technical measurements, data and system diagnostics.
• Analytical and solution-oriented mindset with a natural curiosity to investigate and understand technical issues.
• Ability to combine information from multiple sources, identify patterns and systematically determine root causes.
• Comfortable working with dashboards, digital tools and new technical systems in a fast-evolving environment.
• Strong communication skills, enabling you to explain complex technical findings clearly to customers, colleagues and partners.
• Experience with EV charging, DC power systems, power electronics, electrical installations, OCPP, technical support or field service is an asset; professional proficiency in English and Dutch or French is required.
• You're willing to travel onsite occasionally when a case requires hands-on investigation.

Why this role? 

You'll work at the intersection of electrical engineering, data and customer support.

Rather than simply processing tickets, you'll investigate technical cases, develop deep expertise in EV charging and help turn complex technical information into solutions for installers and partners.

As your expertise grows, you'll have the opportunity to take ownership of increasingly complex DC cases and contribute to how Smappee improves its products, diagnostics and technical support.
