Post description

As part of the continued growth of our industrial activities, Cailabs is creating a dedicated Maintenance team to structure and standardize the maintenance of its equipment, technical facilities, buildings, and utilities across its Rennes sites.

More specifically, your responsibilities will include:

Manage building and utilities maintenance

  • Ensure preventive and corrective maintenance of technical installations and utilities, including electrical systems, HVAC, compressed air, general equipment, access control, alarms, and fire safety systems.
  • Plan regulatory inspections, ensure compliance of installations, and coordinate the resolution of any identified non-compliance issues.
  • Identify requirements for construction work, site improvements, or investments, and provide technical expertise to the Facilities team.

Ensure equipment maintenance

  • Define and implement preventive and corrective maintenance plans for equipment, test benches, and tooling.
  • Monitor the calibration of measurement equipment.
  • Organize fault diagnosis, prioritize interventions, perform root cause analysis, and ensure equipment is safely returned to service.
  • Ensure full traceability of maintenance operations, maintain technical documentation, manage critical spare parts, and oversee the use of the CMMS.

Drive maintenance performance

  • Define and monitor KPIs, including availability, MTBF, MTTR, preventive maintenance completion, recurring failures, costs, energy consumption, and compliance.
  • Prepare and monitor the Maintenance budget and recommend CAPEX/OPEX trade-offs.
  • Lead continuous improvement initiatives to enhance the reliability of equipment and installations.

Ensure safety and coordinate external partners

  • Ensure compliance with HSE requirements, prevention plans, permits, and lockout/tagout procedures, and contribute to the organization of fire drills.
  • Manage suppliers and service providers within the Maintenance scope, in coordination with Procurement and the Facilities team.
  • Provide regular reporting to site management.

Profile required

You hold a Bachelor’s or Master’s degree in Maintenance, Facilities Management, Energy Engineering, Industrial Engineering, Electrical Engineering, or have equivalent professional experience.

You have 5 to 10 years of experience, with significant hands-on experience in the maintenance of production or technical equipment, building and utilities management, regulatory compliance, and contractor management. Previous experience in team management or resource coordination is also expected.

You have strong expertise in preventive and corrective maintenance, CMMS tools, reading technical drawings and schematics, and problem-solving methodologies such as FMEA, 5 Whys, or 8D.

You also have knowledge of electrical systems, HVAC/utilities, maintenance safety requirements, and budget management.

You have a professional level of English, enabling you to work with technical documentation and communicate effectively with suppliers.

Why join Cailabs in this role?

You will join at a key moment, as the Maintenance team is being built from the ground up.

This position combines hands-on technical work, coordination, compliance, project management, budget management, and continuous improvement, with a direct impact on the safety, business continuity, and performance of our Rennes sites.
