Laboratory Technician

At Liquid Stack, you will help validate and scale the cooling systems powering the next generation of AI infrastructure. As AI, high-performance computing, and hyperscale data centers push thermal limits beyond what traditional systems can support, our liquid cooling technologies are enabling a fundamental shift in how data centers are designed and operated.

We are seeking a hands-on Laboratory Technician (Engineering Technician) to play a critical role in system-level validation, rapid prototyping, and performance optimization of advanced liquid cooling solutions. Reporting to the Director of R&D, you will work across component, system, and rack-level environments, contributing directly to product development and real-world deployment readiness.

This role is ideal for someone who wants to move beyond executing test procedures and into owning complex validation environments, influencing engineering decisions, and working on cutting-edge infrastructure at scale.

What You’ll Do

• Own system-level testing and validation of liquid cooling solutions across lab and rack-scale environments
• Build, configure, and operate complex test systems, including fluid loops, sensors, instrumentation, and data acquisition platforms
• Partner with engineering to design, modify, and optimize experimental setups
• Execute and adapt test plans in a fast-paced, iterative R&D environment
• Troubleshoot and debug integrated systems, identifying root causes across mechanical, thermal, and fluid domains
• Analyze and interpret data to identify performance trends, anomalies, and optimization opportunities
• Contribute to test automation and efficiency improvements, including scripting, controls, or process enhancements where applicable
• Maintain high standards for data integrity, documentation, and repeatability
• Ensure compliance with safety standards and operational protocols

Technical Scope & Tools

You will gain hands-on experience with:

• Data acquisition systems (DAQ, LabVIEW, PLC-based controls, or similar)
• System-level debugging of fluid, thermal, and mechanical systems
• Rack-level test environments simulating real-world data center conditions
• Integration of cooling systems with broader infrastructure environments

What You Own

• End-to-end execution and reliability of test setups and validation workflows
• Accuracy, quality, and usability of experimental data
• Readiness and performance of lab infrastructure and equipment
• Continuous improvement of lab processes, scalability, and efficiency

What Success Looks Like

• You independently build and execute complex test environments
• Your data directly informs and improves engineering design decisions
• You proactively identify issues and drive solutions end-to-end
• You improve lab efficiency, scalability, and repeatability over time
• You operate effectively in a high-speed, evolving R&D environment

This role is designed as a pathway into:

• Advanced R&D or Test Engineering roles
• System validation and product engineering
• Lab leadership within a rapidly scaling organization

Associate degree or higher in Mechanical Engineering, HVAC, Thermal Systems, or related field
Strong problem-solving, organizational, and communication skills

• Engineering lab, R&D, or hardware validation environments
• Thermal, fluid, mechanical, or HVAC systems

Strong experience with:

• System-level testing and complex lab setups
• Instrumentation, sensors, and data acquisition systems
• Charging, recovering, and handling of common refrigerants in a research lab
• Troubleshooting across mechanical, thermal, and fluid systems

Familiarity with:

• Liquid cooling, CDUs, immersion cooling, or DTC systems (preferred)
• Data center infrastructure or high-performance computing environments (preferred)

Experience or interest in:

• Willingness to travel up to 5%
• Valid passport and driver’s license
• Ability to meet background check and screening requirements
