Principal Sustaining Engineering Manager - SparkActive$225K–$255K

The opportunity

Crusoe is on a mission to accelerate the abundance of energy and intelligence . As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads.

What you'll do

  • Year 1 Ramp & Handover: Participate in production release and ramp readiness reviews for deploying generations as the receiving organization. Establish as-built baselines, spares strategies, service intervals, and repair-vs-replace policies prior to initial fleet launch.

  • Facility Operations Feedback Loop: Serve as the primary engineering interface with the Data Center Facility Operations team. Gather site-level field feedback across broader facility power, thermal, and environmental systems to analyze how site-wide operational dynamics impact individual Spark modules.

  • Fleet Reliability: Own subsystem failure rates, mean time between failures (MTBF), and repeat failure metrics. Define the required telemetry every deployed unit must report to ensure operational visibility.

  • Closed-Loop Corrective Action: Stand up and run the Failure Reporting, Analysis, and Corrective Action System (FRACAS ) function. Drive root-cause analysis to closure with verified fixes, containing safety or fleet-wide risks immediately when issues arise.

  • Post-Release Change Control: Own engineering change orders (ECOs) for fielded generations, quantifying cost and fleet impacts prior to approval.

  • Configuration Baseline: Maintain as-built and as-maintained configuration baselines, ensuring field retrofits precisely target affected units.

What they're looking for

  • Proactive Component Obsolescence: Manage component lifecycles using Diminishing Manufacturing Sources and Material Shortages (DMSMS) practices - modeling last-time buys against fleet demand and qualifying alternate parts before component shortages occur.
  • Retrofits & Maintenance: Issue change packages, preventive maintenance schedules, and acceptance criteria for Field Operations execution.
  • Requirements into Product: Convert fleet and facility operations data into quantified design requirements for future Product Requirement Document (PRD) iterations.
  • Qualification into NPI: Supply field-derived acceptance criteria to NPI, ensuring historical failure modes are designed out of future module generations before release.
