Determine where to self-perform and where to contract regional O&M partners as the fleet’s geography widens.
KPIs & Performance Improvement
Define the operating KPI incl. availability, performance and identifying the most cost-effective operations techniques and actions.
Build the capacity model incl. staff per MW, cycle time per deployment to ensure growth is planned rather than being reactive
People Leadership & Capability Building
Build, mentor, and develop a high-performing team, fostering a culture of technical superiority, collaboration and accountability.
Build and structure the operations organization to be right sized for multiple stages for growth
Design training programs that lets Critical Loop develop technicians internally and externally rather than competing for scarce experienced hires.
Requirements
Required
Bachelor’s degree in Electrical Engineering, Power Systems, or a related technical field, or equivalent practical experience.
10+ years in field operations, commissioning, or service within energy storage, distributed generation, critical power, or a comparable field-deployed power business, with 5+ years leading teams.
Has run a 24/7 field service or fleet operation against uptime or response-time commitments, including on-call rotations and escalation management.
Deep hands-on electrical competence: switchgear, inverters and power conversion systems, transformers, and controls.
Has built and run a commissioning program from scratch incl test procedures, crew certification, defect tracking, and turnover documentation
Has owned an operations budget and shaped service agreements, LTSAs, or warranties with OEMs and contractors.
Based in or willing to relocate to Southern California, with willingness to travel to customer sites in North America.
Preferred
Experience with mobile, temporary, or rental power fleets in addition to permanently sited assets.
Utility utility coordination and interconnection of behind-the-meter assets
Commercial and industrial customer environments: manufacturing, EV charging, and critical infrastructure and data centers.
Experience in a startup or early-stage environment, including building functions that did not previously exist.
