Job description

Own thermal stability and mechanical reliability in a scaling deep-tech factory

At Smart High Tech, we are industrialising advanced graphene‑based materials that enable next‑generation AI systems, electronics, and data centres - where thermal performance is mission‑critical.

As we scale production, cooling performance and mechanical reliability become defining factors for quality, uptime, and efficiency.

We are looking for a Senior Maintenance Technician – Mechanical & Cooling Systems who will take ownership of this critical domain.

Your mission

You ensure that our production environment operates with stable thermal conditions and high mechanical reliability.

You are:

• technical authority in mechanical systems and cooling
• key driver of uptime, energy efficiency, and asset longevity
• central contributor to stable, scalable production

What you will do

Maintenance & operational reliability

• Perform preventive and corrective maintenance on mechanical systems, furnaces, and cooling systems
• Work across hydraulics, pneumatics, and thermal processes
• Lead advanced fault diagnosis in cooling and temperature control systems
• Monitor and ensure correct performance of temperature, flow, and pressure systems
• Prevent and manage risks such as overheating, leakage, corrosion, and reduced cooling capacity
• Maintain and update technical documentation

Continuous improvement & system performance

• Drive root cause analysis and long‑term corrective actions
• Apply reliability‑centred maintenance and predictive maintenance methods
• Improve equipment lifetime, energy efficiency, and system stability
• Identify recurring issues and implement sustainable solutions
• Act as a technical mentor within the maintenance team

New equipment & industrialisation

• Participate in installation and commissioning of new production equipment
• Lead mechanical and cooling validation in FAT and SAT
• Verify cooling circuits, thermal processes, and mechanical integrity
• Ensure systems are fully operational before production start

Key interfaces

You will work closely with:

• Facility & Maintenance Manager
• Electrical & Automation Maintenance
• Production & Engineering
• External suppliers and equipment vendors

Who you are

You combine deep technical expertise with ownership and precision.

• Degree in Mechanical Engineering, Industrial Technology, or Cooling Systems
• Certification for refrigerant handling (F‑gas, EU 517/2014)
• Advanced knowledge in hydraulics and pneumatics
• Minimum ~8 years of industrial maintenance experience
• Strong experience with thermal processes and cooling systems
• Experience in:
  • Reliability‑centred maintenance
  • Predictive maintenance
  • CMMS systems
• Trained in LOTO, pressurised systems, and AFS safety standards

How you work

• Analytical and systematic in troubleshooting
• Proactive in preventing failures – not just reacting to them
• Hands‑on and execution‑focused
• Structured and disciplined
• A trusted expert who elevates team capability

What we offer

This is a role for someone who wants technical ownership in a high‑performance environment.

You will:

• Own systems that directly impact product quality and production stability
• Work with advanced thermal and mechanical processes in a deep‑tech setting
• Be part of scaling a factory from development to global production
• Have real influence on uptime, efficiency, and system design
• Operate in a culture defined by competence, accountability, and execution

What success looks like

Within 6–12 months, you have:

• Established stable and reliable cooling performance across production
• Reduced failures and improved system uptime
• Increased energy efficiency and equipment lifetime
• Contributed to successful commissioning of new systems
