Mechanical Engineer - Liquid Cooling Systems (On-Site Role)Contract | On-site | Competitive Pay (up to $75/hr)OverviewWe are seeking a highly skilled
Mechanical Engineer with deep expertise in
liquid-cooling systems, diagnostics, and telemetry-driven monitoring for high-density compute environments. This role is
on-site at a major data-center facility and requires hands-on engagement with mechanical and cooling systems to ensure reliability, performance, and operational excellence.
Some travel may be required for cross-site alignment. Travel outside a 75-mile round-trip commute is reimbursable.
What You'll DoAs the mechanical engineering lead for liquid-cooling diagnostics and monitoring, you will:
Core Responsibilities- Lead detection, monitoring, alarm triage, and fault isolation for liquid-cooling systems, including CDUs, HRUs, and rack-level cooling loops.
- Respond to alarms and diagnose root causes using telemetry, logs, and system behavior.
- Perform on-site validation of telemetry, dashboards, and fault-detection logic.
- Identify and resolve gaps in telemetry completeness and accuracy.
- Analyze system trends to detect degradation early and recommend corrective action.
- Partner closely with mechanical, electrical, and site-services teams to ensure smooth operational alignment.
- Define requirements for dashboards, KPIs, alerts, and monitoring tools.
- Work with developers and project managers to translate real-world system behavior into telemetry-driven detection logic.
- Provide consistent weekly updates outlining findings, risks, and improvements.
- Support ongoing efforts to enhance reliability, uptime, thermal performance, redundancy, and energy efficiency.
Top Required Skills1. Liquid Cooling Systems Expertise (3+ years)- Hands-on experience with CDUs, HRUs, direct-to-chip cooling, racks, and fluid-cooling loops.
- Strong ability to assess cooling performance through flow, temperature, and pressure behavior.
2. Telemetry Interpretation & Fault Diagnostics (3+ years)- Skilled at root-cause analysis using sensor data, logs, alarms, and telemetry streams.
- Able to detect early performance degradation using trend analysis and system correlations.
3. Mission-Critical Mechanical Engineering (8+ years)- Experience in data centers, HPC facilities, or mechanically intensive environments.
- Deep understanding of mechanical, thermal, and facilities engineering for high-availability systems.
Strong communication skills are essential to support daily interaction with on-site engineering teams.
What Success Looks Like- Liquid-cooling systems operate with minimal downtime and zero customer impact.
- Dashboards and telemetry signals deliver fast and accurate diagnostics.
- Strong relationships formed with on-site engineering teams.
- Early detection of mechanical or thermal degradations before operational disruption.
- Reliable translation of physical system behavior into monitoring logic and alerting requirements.
- Continual improvement in system reliability, efficiency, and monitoring capability.
What we are looking for- Deep hands-on expertise in liquid cooling within mission-critical environments.
- Exceptional diagnostic instincts and the ability to tie real-world system behavior to telemetry.
- Strong collaboration across technical and operational teams.
- Ability to define, validate, and continuously refine detection logic and KPIs.
- Proactive mindset toward risk identification and system improvement.
- Clear, consistent communication.
- General mechanical engineering experience but limited exposure to liquid cooling.
- Follows existing processes but struggles to define improvements.
- Needs guidance to spot telemetry gaps or degradation patterns.
- Collaborates well but doesn't build deep cross-team technical trust.
- Relies heavily on documented procedures rather than independent diagnostic judgment.
Key SkillsMechanical engineering, liquid-cooling systems, telemetry, data analysis, fault isolation, diagnostics, facility engineering, monitoring tools, relationship building, cross-functional collaboration.
