• Collaborating with Support Engineers for fast root‑cause analysis and long-term solutions.
• Monitoring contractual KPIs such as uptime, response times and turnaround times.
• Identifying and advising on improvement opportunities (product, process, service).
• Participating in on‑call duties and shift work when required.

What do you bring?

• VCA VOL (BHV is a plus).
• Excellent command of Dutch and English (spoken and written).
• A driver’s licence (B), strong self‑organisation skills and flexibility (on‑call/weekend/evening).
• Willingness to travel frequently within the Netherlands and occasionally abroad.
