Senior Maintenance Technician – Mechanical & Cooling Systems

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:

• The technical authority in mechanical systems and cooling

• A key driver of uptime, energy efficiency, and asset longevity

• A 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
