Precision Motion & Mechatronics (Leuven)

Bridge high-tech engineering with customer success and shape the future of micro-motion technology.

Are you an experienced technical specialist eager to drive customer success in a fast-growing scale-up? As a Senior After Sales Engineer at Xeryon in Leuven, you will take ownership of high-impact customer integrations, troubleshoot complex mechatronic systems, and serve as the vital link between clients and our R&D teams.

What will you do?

As a Senior After Sales Engineer at Xeryon, you will play a central role in ensuring a seamless customer experience across the full lifecycle of our precision motion systems. You will autonomously guide international clients through complex integrations, system setups, and advanced diagnostics.

By taking full ownership of key account relationships, you will bring structure to root-cause analysis and long-term issue resolution. Beyond troubleshooting, you will translate real-world technical data into product improvements, helping shape our future development roadmap; thus acting as a strategic liaison between end users and Xeryon's engineering teams.

This role is ideal for a hands-on engineer who thrives in a fast-paced scale-up environment where deep technical expertise meets strong customer communication.

In this role, you will mainly focus on the following core responsibilities:

• Customer Integration & Onboarding: Serving as a trusted technical advisor, you proactively lead clients through complex product setup, system configuration, and second-line technical support for firmware, electronics and control systems; also by providing remote troubleshooting.
• Root-Cause Analysis & Diagnostics: Take ownership of escalated customer issues. Analyze communication protocol traces and system logs to resolve advanced issues and establish systemic quality improvements.
• Quality & Automated Testing: Collaborate with the quality organization to write automated testing protocols using Python. Implement rigorous quality checks. Prioritize and categorize recurring issues, contributing to systemic solutions rather than one-off fixes.
• Product Development Liaison: Represent the "voice of the customer" in cross-functional discussions to drive usability, system stability, and feature enhancements.
• Documentation & Knowledge Sharing: Create high-quality integration guides, troubleshooting documentation, and deliver technical training to clients and internal teams.

Tools & Working Environment: You will work directly with precision motion systems, embedded controls and communication protocol analyzers. The role involves cross-functional collaboration with R&D, Quality, and Product teams, with periodic international travel for on-site product set-up, configuration, testing or diagnostics.

Who are we?

Xeryon is a fast-growing, Leuven-based high-tech scale-up revolutionizing precision positioning with innovative micro-motor technology.

At Xeryon, you will join a close-knit, highly skilled team of passionate professionals in an energetic culture focused on autonomy, innovation, and global impact.

Who are we looking for?

To excel in this role, your high degree of autonomy allows you to take full ownership of complex technical challenges without needing step-by-step guidance.

Your strong interpersonal and communication skills enable you to manage key account relationships and bridge technical gaps between end-users and internal developers.

Finally, your analytical mindset ensures you can quickly diagnose root causes within complex embedded systems and communication protocol traces.

To qualify for this position, you must meet the following technical requirements:

• Education: Bachelor's degree in Electronics, Automation, Mechatronics, or a related field (or equivalent practical experience).
• Experience: 3 to 7+ years in a customer-facing technical role (e.g., Field Application Engineer, Technical Support Engineer, or After Sales Engineer).
• Protocol Knowledge: Hands-on experience with communication protocols such as UART, SPI, I2C, CAN, Modbus, TCP/IP, or industrial protocols.
• Scripting Skills: Demonstrated ability to write automated testing protocols using Python.
• Language & Mobility: Fluent in English (proficiency in Dutch is a significant advantage) and willingness to occasionally travel (single or multi-week trips, max 25%).

Added bonuses would be:

• Experience with precision motion systems, servo drives, embedded systems, or high-tech instrumentation.
• Basic understanding of mechanical design.
• Experience in scale-up or fast-moving high-tech environments.

What do we offer?
