Location: Carrollton, TX
Reports to: Director of R&D
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
