Lab Technician Vacancy at Heidelberg Materials, Engis

Heidelberg Materials Benelux is seeking a Laboratory Technician (Aggregates Quality) for its Engis (Liège Province), Belgium production site. The position suits a careful laboratory professional or a candidate with equivalent practical experience who is comfortable moving between sampling activity, test work and conversations with production colleagues. It calls for disciplined record keeping, sound judgement and a close interest in how aggregate quality is maintained on site.

Based in the Quality Department (Aggregates), the Laboratory Technician (Aggregates Quality) supports product-quality oversight at Heidelberg Materials Benelux in Engis (Liège Province), Belgium. Applicants who can work methodically, organise their own tasks and communicate clearly when results need attention should find the remit relevant. The work combines defined laboratory procedures with a practical understanding of production installations and collaboration with the local and wider Quality teams.

Opportunity Details

Overview of the Vacancy

Location, Sector, and Role Context

This Laboratory Technician (Aggregates Quality) vacancy is centred on protecting the quality of aggregates manufactured at the Engis production site. Day-to-day work includes collecting samples, preparing them for standard tests, carrying out analyses at set intervals and entering results in dedicated computer tools. The technician follows the quality of manufactured products and turns findings into useful information for production-line action. When results point to a departure from expected quality, the role requires prompt, clear escalation to the relevant production and Quality colleagues. The post therefore combines hands-on laboratory work, structured data recording and close attention to what is happening in production.

The role sits in the Quality Department (Aggregates) and is performed at the Engis site in Wallonia, within Liège Province. It is suited to someone with an upper-secondary diploma or comparable professional experience, particularly where that background has developed care, analytical thinking and confidence with computer tools. Initial exposure to a laboratory, production setting, industry or materials is beneficial but not compulsory. Alongside independent task planning, the technician needs to work constructively with colleagues, learn laboratory-specific tools and remain at ease in field-facing contact with production teams. Training in internal methods and procedures precedes the expected autonomous contribution.

Within the Engis Quality Department, the Laboratory Technician (Aggregates Quality) provides the factual testing and follow-up that supports aggregate product-quality control. The work begins with correctly obtained and prepared samples, continues through standardised analysis and computer-based recording, and extends to communicating results that may require production action. It also involves preventive thinking: recognising potential deviation risks, helping to identify their source and proposing corrective or improvement measures. Proper laboratory-equipment use, participation in quality discussions and audit activity are part of the stated remit, alongside compliance with site quality, safety and environmental instructions.

Responsibilities

• Collect samples and carry out analyses in line with the specified procedures and testing frequencies.
• Record analysis outcomes in the laboratory's designated computer tools.
• Check and follow the quality of products manufactured at the Engis aggregates operation.
• Recognise departures from requirements and communicate them promptly to production and Quality colleagues.
• Relate test findings to actions that need to be taken on the production line.
• Contribute to early identification of deviation risks and put forward corrective or improvement actions.
• Oversee the appropriate use of laboratory equipment in cooperation with the central laboratory.
• Take part in quality meetings and internal and external audits while observing quality, safety and environmental instructions.
• Perform standard tests covering sample preparation, quartering, washing, drying, particle-size analysis, flakiness coefficient, cleanliness, methylene-blue value and sand equivalent or flow testing.
• Build knowledge of manufacturing processes and installations to help trace quality issues and, after training and autonomous practice, support the wider Quality team, especially the Engis laboratory technician.

Qualifications

• Hold an upper-secondary education diploma or bring equivalent professional experience.
• Demonstrate rigour, punctuality and close attention to detail in practical work.
• Use critical thinking when assessing results or situations.
• Work independently, organise time effectively and contribute as part of a team.
• Be comfortable with computer tools and willing to learn the laboratory's dedicated tools.
• Be at ease with field work and contact with production teams, and communicate clearly when a result or situation needs intervention.
• Select fluent spoken and written language or languages on the application form from French, Dutch and English; no driving-licence requirement is stated.
• Hold valid authorisation to work in the European Union, as visa or work-permit sponsorship is not available.
• Preferred: Bring initial experience in a laboratory, production, industrial or materials setting.

Skills and Competencies

• Apply sampling and laboratory sample-preparation practices to aggregate materials.
• Carry out standardised aggregate or material tests with careful adherence to procedure.
• Use particle-size analysis as part of the stated testing programme.
• Monitor product quality and report non-conforming findings to the appropriate colleagues.
• Recognise deviation risks early and contribute to corrective-action thinking.
• Follow laboratory equipment use in coordination with the central laboratory.
• Enter results accurately in computer-based laboratory information tools.
• Communicate clearly with production personnel when findings require action.
• Balance independent organisation with effective collaboration in the Quality Department.

Benefits and Employment Information

• The employer states that the package includes a range of extralegal benefits, without listing the individual benefits.
• Training programmes and talent-development plans are stated as part of the offer.
• The employer refers to support for work-life balance.
• The stated work setting offers room for initiative and growth within an inspiring and stimulating environment.
• This Laboratory Technician (Aggregates Quality) position is full-time and on-site at the Engis aggregates production site; the employer describes an attractive compensation package, but publishes no numeric salary amount or exact amount.

Application Guidance

Prepare a Focused Application

CV, Evidence, Documents, and Interview Preparation

As general preparation guidance, candidates for an aggregates laboratory post can organise examples that show how they followed a written test procedure, maintained accurate records or noticed a result needing escalation. It can be useful to describe the part personally played in sampling, sample preparation, data entry or coordination with production colleagues, without overstating experience. Someone with a school qualification or equivalent work history may also prepare a concise account of how accuracy, punctuality and critical thinking were applied in a practical setting. This is general advice rather than an additional employer requirement.

For a conversation about this type of position, applicants can be ready to discuss how they would sequence laboratory tasks at defined frequencies, protect the traceability of a result and communicate a concern clearly to a production colleague. General preparation may also include reviewing prior exposure to particle-size work, material handling, washing, drying or comparable standard testing, where applicable. Candidates without direct laboratory experience can focus on transferable examples of careful procedure-following, computer use, independent planning and teamwork. These preparation points do not replace the qualifications stated for the Engis vacancy.

• Prepare a CV that clearly separates laboratory, production or materials experience from other practical experience.
• List examples of following defined procedures, recording results accurately and checking work for detail.
• Be ready to explain any familiarity with sampling, preparation, particle-size analysis or related standard testing.
• Prepare a concise example of escalating a result or situation to colleagues who needed to act.
• Review how computer tools have been used for data entry, traceability or organised task management.
• Confirm the language selection and European Union work-authorisation information required by the application form.
