Preparation for Imerys requires balancing your technical background with an appreciation for industrial operations. You should arrive ready to discuss how your software solutions can solve concrete, physical-world problems.

Role-related knowledge – We look for candidates who understand the bridge between software and hardware. Be prepared to discuss your experience with industrial control systems or how you have successfully integrated software into physical production workflows.

Problem-solving ability – We value engineers who can troubleshoot under pressure and maintain a logical approach in ambiguous situations. During your interview, walk the interviewer through your thought process when you encounter a technical roadblock or a complex project requirement.

Leadership and collaboration – As you will work with diverse teams, including research scientists and plant operators, your ability to communicate complex technical ideas to non-technical stakeholders is essential. Highlight examples where you successfully navigated conflict or managed a project to completion.

Culture fit – Imerys is a company that values professionalism and a clear understanding of our market position. Demonstrating that you have researched our business model and understand our role as a mineral-based specialty solution provider will set you apart.

The Imerys interview process is generally characterized by a mix of professional, structured conversations and on-site engagement. You can expect an initial screening—usually via telephone—with a Human Resources representative to discuss your background and interest in the company. If successful, you will progress to interviews with hiring managers and key technical team members.

The process is designed to be thorough yet collaborative. In many instances, candidates are invited to tour our facilities, which provides a unique opportunity to see the operational environment firsthand. Our philosophy focuses on finding candidates who are not only technically proficient but also curious and adaptable to the unique demands of an industrial setting.

The visual timeline above outlines the typical progression from your initial application to the final selection stages. Candidates should use this as a guide to manage their preparation energy, ensuring they are ready for both the high-level behavioral discussions early on and the more specific technical inquiries later in the process. Remember that the rigor can vary based on the specific location and the seniority of the role.

Industrial Systems Proficiency

Understanding how software interacts with physical hardware is a key differentiator. We look for candidates who can bridge the gap between abstract code and concrete machinery.

Be ready to go over:

• PLC Integration – Understanding how software communicates with controllers.
• Hardware-Software Interface – Managing data flow between sensors, machines, and software.

As a Software Engineer at Imerys, you are responsible for developing, maintaining, and optimizing software solutions that support our manufacturing processes. You will collaborate closely with cross-functional teams, including production engineers and data scientists, to ensure that our digital tools are robust, scalable, and user-friendly.

Your day-to-day work often involves translating complex industrial requirements into clean, functional code. You might find yourself debugging a control interface in the morning and collaborating with a research team on a process improvement project in the afternoon. Success in this role requires a proactive mindset, as you will often need to step onto the plant floor to understand the challenges firsthand and build solutions that truly move the needle for our operations.

A strong candidate for this position brings a combination of hands-on technical skill and a pragmatic approach to problem-solving.

• Must-have skills:
  • Proven experience in software development within an industrial or engineering context.
  • Familiarity with industrial automation protocols and equipment, such as Allen Bradley or similar PLC platforms.
  • Strong project management skills and the ability to work independently on complex tasks.
• Nice-to-have skills:
  • Experience in data analysis or process optimization.
  • Familiarity with modern software development lifecycles (SDLC) adapted for embedded or industrial systems.
  • Excellent communication skills to bridge the gap between technical and operational departments.

Q: How long should I expect the interview process to take? A: Timelines can vary based on the location and specific project needs, but typically the process moves from an initial screening to final interviews over a few weeks. We aim for a professional and clear communication flow throughout.

Q: What is the most important thing to emphasize during the interview? A: Highlight your ability to apply software solutions to real-world, physical problems. We value engineers who are practical, curious, and comfortable working in an industrial setting.

Q: Is the work environment mostly remote or on-site? A: Given the nature of our work, many roles require significant on-site presence to collaborate with the engineering teams and observe production processes directly.
