At LCL, we listen to our customers and invest in lasting relationships. We take the same long-term approach to our work, with a strong focus on quality, safety, health and the environment.

What you do as a critical infrastructure engineer at LCL?

As a Critical Infrastructure Engineer, your expertise will be essential to keeping the technical systems in LCL’s data centers reliable and energy-efficient. You will be based primarily in Aalst, with occasional visits to other sites. You will help ensure maximum infrastructure availability and a safe working environment.

  • Manage and improve the electrical installations across our data centers.
  • Develop in-depth knowledge of our electrical infrastructure and act as a go-to person for technical questions.
  • Keep up to date with relevant standards, legislation and manufacturers’ requirements, and apply them in practice at LCL.
  • Plan maintenance and interventions with business continuity and EHS risks in mind. Prepare standard and method-of-procedure documents (SOPs/MOPs), risk assessments and method statements (RAMS), and the necessary permits to work.
  • Supervise maintenance contractors, check the quality and safety of their work, and ensure procedures are followed correctly.
  • Carry out technical inspections, interventions and electrical switching operations yourself, within your authorisations and in line with safety procedures.
  • Maintain accurate technical and administrative records, from work orders and asset data in the CMMS to electrical documentation and as-built information.
  • Drive technical improvements and support project managers with infrastructure upgrades and expansion projects.
  • Act as the technical escalation point for incidents at the Aalst site, coordinating recovery actions and technical root-cause analysis.
  • Take part in the technical on-call rota.

In this varied and challenging role, you will report to the Critical Infrastructure Site Coordinator and work closely with colleagues across the LCL Operations team.
