Principal Sustaining Engineering Manager - Spark

The role

The Sustaining Engineering Leader owns the performance of Spark physical modules post-deployment. This person drives continuous improvement by managing fleet reliability, field failures, configuration, and component obsolescence.

What you will do

• Participate in production release and ramp readiness reviews.
• Establish as-built baselines, spares strategies, service intervals, and repair-vs-replace policies.
• Serve as the primary engineering interface with the Data Center Facility Operations team.
• Own subsystem failure rates, mean time between failures, and repeat failure metrics.
• Define required telemetry for deployed units.
• Run the Failure Reporting, Analysis, and Corrective Action System (FRACAS) function.
• Drive root-cause analysis to closure.
• Own engineering change orders (ECOs) for fielded generations.
• Maintain as-built and as-maintained configuration baselines.
• Manage component lifecycles using DMSMS practices.

Required qualifications

• Bachelor's degree in Mechanical, Electrical, Reliability, or a closely related engineering discipline.
• 10 to 15 years in sustaining, reliability, or product support engineering for deployed capital hardware or infrastructure assets.
• Track record of converting field performance data into design changes that reduce failure rates and service costs.
• Experience building sustaining engineering processes from the ground up.
• Hands-on management of component obsolescence and supplier end-of-life transitions.
• Reliability Engineering: FRACAS, structured root-cause analysis (8D, 5-Why), MTBF modeling, and population failure rate analysis.
• Configuration Management: PLM workflows, serial-level effectivity, change order management, and as-built control.
• Obsolescence & Service Economics: DMSMS practices, last-time buy modeling, spares planning, and unit service cost drivers.

Nice to have

• Experience with modular, containerized, or prefabricated infrastructure products in the field.
• Direct familiarity with liquid-cooled data center hardware.
• The persistence to chase root causes past obvious answers, paired with the practical judgment needed to manage fleet disruptions.

Benefits
