Mechanical Engineer - Data Centers

Description
LOCATION & ON-SITE EXPECTATIONS:
This role requires regular on-site presence at the designated data center (one role will be in MWE, on in PHX).
On-site work is critical for:
- Understanding mechanical and liquid-cooling system behavior
- Building trust with mechanical, electrical, and site services teams
- Validating telemetry, dashboards, and fault-detection logic directly within the environment
*Some travel may be required for cross-site alignment and system comparison. All travel outside of a 75-mile roundtrip commute is eligible for reimbursement.
TEAM OVERVIEW:
The Signals Quality team specializes in designing, customizing, and deploying telemetry-driven detections across global datacenter environments. You will join a cross-functional engineering + data/telemetry project composed of your PM, a data scientist, and two developers. The team's mission is to ensure high-density compute racks operate with minimal downtime and zero customer impact by improving monitoring, diagnostics, and liquid-cooling system performance.
PROJECT OVERVIEW:
High-density compute racks rely on advanced liquid and hybrid cooling systems (including CDUs, HRUs, and rack-level cooling loops). The program's goal is to strengthen:
- Telemetry completeness
- Monitoring and alerting capabilities
- Diagnostic logic
- System reliability and operational efficiency
Telemetry from Atlanta (a more mature site) will serve as an early reference model for what the MWE/PHX environment will eventually receive as data onboarding progresses.
THIS ROLE'S CONTRIBUTION:
The Mechanical Engineer will serve as the diagnostics and monitoring lead for liquid cooling. Your work directly supports the project by:
- Ensuring relevant telemetry is available, complete, and accurate
-Rapidly detecting cooling system degradations
- Defining requirements for dashboards, alerts, and monitoring tools
- Ground-truthing data signals through on-site inspection
- Helping developers and PMs align monitoring logic with real equipment behavior
- Bridging operational engineering teams with the data/analytics team
DAY TO DAY RESPSONSIBILITIES:
- Lead detection, monitoring, alarm triage, and fault isolation for CDUs, HRUs, and rack-level liquid-cooling systems.
- Respond to alarms and perform rapid root cause analysis using telemetry, system data, logs, and trend patterns.
- Conduct on-site validation of telemetry, dashboard logic, and system behavior by spending time on the data-center floor.
- Identify and close telemetry gaps, including missing, inaccurate, or incomplete signals critical to system health and performance.
- Analyze system performance trends to detect early signs of degradation and recommend corrective actions.
- Build and maintain strong working relationships with mechanical, electrical, and site services engineers to ensure seamless collaboration without disrupting operations.
- Define requirements for dashboards, alerting logic, KPIs, and visualization tools, ensuring they support fast and accurate diagnostics.
- Collaborate closely with PMs and developers to translate real-world system behavior into monitoring logic and tooling features.
- Provide weekly progress updates, documenting findings, issues, risks, and opportunities for improvement.
- Support continuous enhancements to reliability, thermal performance, redundancy, and energy efficiency across liquid-cooling systems.
TOP 3 SKILLS:
1. Advanced Liquid Cooling Systems Expertise - Expert Level
1. 3+ YOE Liquid Cooling Systems Expertise
- Hands-on experience with CDUs, HRUs, direct-to-chip cooling, racks, and cooling loops.
- Ability to diagnose system behavior, understand flow/temperature/pressure dynamics, and respond to system faults.
2. 3+ YOE Telemetry Interpretation & Fault Diagnostics
- Ability to perform root cause analysis based on telemetry streams, sensors, alarms, and system logs.
- Skilled at identifying degraded performance early through trend analysis and correlating telemetry with physical system behavior.
3. 8+ YOE Mission-Critical Mechanical Engineering
- 8+ years in data centers, HPC facilities, or mechanically intensive industrial environments.
- Strong understanding of mechanical, thermal, and facilities engineering fundamentals in high-availability systems.
** Strong communication is necessary for the management of on-site relationship
SUCCESS IN THIS ROLE LOOKS LIKE:
- Ensure the liquid-cooling systems operate with minimal downtime and zero customer impact.
- Deliver dashboards and telemetry signals that provide fast, accurate fault detection.
- Establish strong, trusted relationships with onsite engineering teams.
- Identify early signs of thermal or mechanical degradation before they become operational issues.
- Translate real-world system behavior into high-quality monitoring logic and tooling requirements.
- Improve system reliability and operational efficiency over time.
BEST VS AVERAGE:
Best:
- Deep, hands-on expertise with liquid cooling in mission-critical data center or HPC environments.
- Extremely strong diagnostic instincts, able to correlate telemetry with physical system behavior.
- Outstanding collaborator who integrates seamlessly with both site engineers and data teams.
- Comfortable creating, validating, and refining monitoring logic, KPIs, and dashboard requirements.
- Proactively identifies system risks, telemetry gaps, and improvement opportunities.
- Communicates clearly, effectively, and consistently.
Average:
- Has mechanical engineering experience but not specifically with liquid cooling systems.
- Can follow monitoring procedures but struggles to define or improve them.
- Requires direction to identify telemetry gaps or degradation trends.
- Collaborates effectively but may not build the deep cross-team trust this role requires.
- Relies more on documented steps than independent diagnostic judgment.

Additional Skills & Qualifications
- Experience collaborating with data or software teams is highly valued even if not required.
- This is not a purely mechanical design role - diagnostics, monitoring logic, telemetry interpretation, and cross-functional communication are central.
- On-site presence is not negotiable: much of the role's success depends on building relationships and validating telemetry in person.
