• Troubleshooting a database bottleneck that is causing a delay in inventory tracking on the packaging floor.

Industrial Problem Solving & Engineering Logic

Our interviewers value core engineering intelligence over rote memorization of coding syntax. You will be evaluated on your logical approach to debugging, system optimization, and physical-to-digital troubleshooting.

Be ready to go over:

• Root Cause Analysis – Methodically identifying the source of system failures that span both software and hardware interfaces.
• Performance Optimization – Streamlining code execution and resource utilization to run efficiently on on-premise industrial servers.
• Legacy Code Modernization – Refactoring and updating older codebase architectures without disrupting active manufacturing operations.
• Advanced concepts – PLC (Programmable Logic Controller) communication protocols, OPC UA standards, and network socket programming.

Example scenarios:

• Explaining how you would isolate a bug when a packaging sensor stops sending data to your tracking software.
• Discussing your approach to refactoring an outdated data logging script that frequently crashes under heavy loads.

Operational Collaboration & Safety

A successful Software Engineer at Perfetti Van Melle must operate effectively within a physical plant environment. This area evaluates your communication skills, safety consciousness, and ability to work with multidisciplinary teams.

Be ready to go over:

• Stakeholder Communication – Translating technical software bugs or requirements into clear operational impacts for floor supervisors and plant managers.
• Safety-First Development – Designing software with physical safety in mind, ensuring that system errors do not create hazardous conditions on the production floor.
• Conflict Resolution – Navigating differing priorities between fast software deployment cycles and conservative plant operational schedules.

Example scenarios:

• Describing a past experience where you had to halt a software deployment due to an identified safety risk.
• Explaining how you gathered software requirements from floor operators who had limited technical backgrounds.

As a Software Engineer at Perfetti Van Melle, your day-to-day responsibilities will keep you deeply connected to both the digital and physical aspects of confectionery production. You will spend your time designing and maintaining the software applications that monitor, control, and optimize our manufacturing processes. This involves writing clean, reliable code that interfaces with industrial automation systems and packaging machinery.

Collaboration is a core component of this role. You will work side-by-side with Packaging Engineers, automation technicians, and floor supervisors to implement software updates, integrate new machinery into the digital network, and troubleshoot operational bottlenecks. For example, when a new packaging line is installed, you will be responsible for configuring the software interfaces that track packaging speed, material usage, and quality control metrics.

Additionally, you will drive continuous improvement initiatives. This includes analyzing system performance data, identifying areas for automation, and developing custom software tools to help operators monitor production metrics in real-time. Your work ensures that our plants operate at peak efficiency, minimizing waste and ensuring that millions of candies reach consumers worldwide safely and on time.
