Job Description - Test Engineer, Liquid Cooling

Overview

We are hiring a Test Engineer to lead test engineering for liquid-cooled AI, server, networking and storage platforms in a high-volume manufacturing environment.

You will play a critical role in the development, integration and continuous improvement of next-generation compute platforms, including AI/ML, GPGPU, server, networking and storage systems. You will drive product quality, system performance and operational excellence through advanced troubleshooting, automation and team leadership, and join a team that is driving innovation and growth in advanced computing technologies powering enterprise and AI-driven environments.

Key responsibilities

The role combines hands-on technical work across compute hardware and liquid-cooling systems.

Technical leadership and engineering

Design, develop and maintain test procedures, test systems, hardware and software for advanced compute platforms.

Lead failure analysis and root cause investigations across hardware and software domains.

Troubleshoot complex server, networking, storage and accelerator-based systems.

Support AI/ML, GPU and high-performance compute platforms through integration and production.

Interpret test logs, JSON outputs and system data to identify trends and drive improvements.

Develop and deploy automation using Python and Bash scripting.

Analyze manufacturing and system data using Excel and Power BI.

Support New Product Introduction (NPI) readiness and production ramp.

Networking and systems

Configure and troubleshoot networking systems (switches, routers, LAN/WAN, Layer 3).

Support optical networking technologies (transceivers, fiber optics).

Use and train others on Linux command-line tools and scripting.

Liquid cooling and thermal systems

Apply heat transfer, thermodynamics and fluid mechanics principles to liquid cooling systems.

Work with pumps, cold plates, chillers, reservoirs, tubing and coolants (e.g. PG25).

Use instrumentation including thermocouples, flow meters and pressure sensors.

Perform leak detection, material compatibility analysis and coolant safety procedures.

Support immersion and direct-to-chip cooling technologies.

Work with OCP standards, BMS/SCADA systems and specialized equipment, including particle analyzers, pressure testers and fill/flush/purge systems.

Leadership and operational excellence

Beyond the technical work, the role leads people, aligns test strategy with site goals and drives operational improvement.

Team leadership

Lead, mentor and develop Test Engineers and technicians.

Recruit, interview and retain top talent.

Build training programs and develop team capabilities.

Performance management

Set measurable goals aligned with operational and business objectives.

Provide coaching, feedback and performance evaluations.

Drive continuous improvement in productivity, quality and engagement.

Business and strategy

Align test engineering strategy with site and organizational goals.

Lead workcell test engineering teams and customer programs.

Present technical findings and communicate effectively with stakeholders and customers.

Operational excellence

Apply Lean manufacturing principles and quality metrics (yield, GR&R, DPPM).

Identify cost reduction opportunities through process optimization and automation.

Monitor test performance and implement improvements across programs.

Qualifications

Candidates need 5+ years in test engineering, failure analysis or hardware validation in a manufacturing environment, plus advanced Linux and scripting skills.

Education

Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science or a related field (preferred).

Experience
