Why this role matters

OptiCool designs and manufactures high performance, energy efficient cooling systems for modern data centers. We specialize in two phase cooling, applied at the rear door, that enables higher rack densities, lowers energy consumption, and enables scalable deployments.

We are currently seeking technicians with strong refrigerant fundamentals, piping/brazing discipline, electrical troubleshooting, documentation habits and comfort in uptimesensitive environments. This role is the front-line technical expert responsible for safe, professional, high-availability support in mission-critical data centers.

• Excellent customer communication and documentation skills; able to write clear field reports and service summaries.
• Valid driver's license; ability to pass background checks as required by customer sites
  
  

Preferred

• Experience supporting refrigerant-based precision cooling, pumped refrigerant loops, or two-phase thermal systems.
• Experience with copper piping practices (including brazing), pressure testing, and cleanliness practices appropriate for refrigerant systems.
• Demonstrated experience working in mission-critical environments (data centers, telecom, fabs, labs, hospitals, etc.) with strong safety and change-management discipline.
• Experience delivering technical training to customers/partners and mentoring junior technicians.
• Experience with FSM/ticketing tools and asset/service record management.
• NFPA 70E / OSHA 10/30 and/or other relevant safety credentials.
