Laboratory Technician

POSITION SUMMARY

At LiquidStack, 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.

ESSENTIAL DUTIES AND RESPONSIBILITIES

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

  Growth & Career Path 

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
