• Build long-term relationships with customers as their trusted technical point of contact
• Stay up to date with trends in the space and electronics industry

What do we look for?

• 3+ years of experience in technical sales, systems engineering or technical project management, ideally in electronics, aerospace or a related high-tech field
• University degree in engineering (electronics, aerospace, mechanical or similar)
• Solid understanding of electronics and hardware systems
• Ability to explain complex technical topics clearly to both engineers and customers
• Fluent English, written and spoken
• A proactive, structured, results-driven approach
