Senior Maintenance Technician – Mechanical & Cooling Systems
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:
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

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
