This principal-level role will support the design, monitoring, optimization, and 24/7 operational leadership of control systems operating facility infrastructure and our customized rack manager architecture. You will ensure precise, stable, and efficient control of high-density liquid cooling (100–150+ kW/rack) to maintain thermal performance, prevent excursions, and support hyperscale AI workloads with maximal uptime and efficiency.This is a senior individual contributor/leader position requiring deep expertise in facility and process control for modern liquid-cooled data center equipment.Key ResponsibilitiesOwn operational control strategy and performance for the site systems, including direct-to-chip liquid cooling controls: flow regulation, pressure/temperature PID loops, pump speed/VFD control, valve sequencing, cold plate thermal response, leak detection interlocks, and dynamic setpoints to sustain optimal GPU/CPU temperatures under variable AI compute loads.Lead controls operations for the facility water loop (secondary/tertiary side), encompassing CDU control logic, heat exchanger approach temperature regulation, redundant pump staging, flow balancing, filtration monitoring, coolant quality sensors, warm-water mode transitions, and integration with facility BMS/PLC for seamless primary-to-secondary heat transfer and energy efficiency.Direct and mentor the operations team in full lifecycle management of the customized rack manager design from a controls perspective: embedded controller firmware, sensor/actuator I/O mapping, control algorithms (PID, feedforward, cascade), HMI/SCADA integration, alarm management, trending/data logging, scripting/automation for setpoint adjustments, fault handling, and rapid diagnostics of rack-level control anomalies.Develop, validate, and refine control sequences, logic diagrams, tuning parameters, and safety interlocks specific to supporting GB300 liquid-cooled systems; implement model-based or adaptive controls where applicable to handle transient loads and maintain stability.Monitor and analyze real-time controls performance metrics (loop stability, response time, overshoot, setpoint tracking, valve/pump duty cycles, sensor drift); perform root cause analysis on control-related excursions, oscillations, or failures; tune loops and update logic to achieve ultra-high reliability (>99.99% thermal availability).Lead incident response, troubleshooting, and remediation for controls issues across TCS, water loop, and rack managers, including on-call support for critical AI clusters.Drive preventive maintenance, calibration, and health checks for controls hardware (PLCs, controllers, sensors, actuators) and software; oversee firmware/patch management and version control for rack managers and CDU controllers.Collaborate with NVIDIA partners, cooling vendors, internal facilities, and AI engineering teams to integrate controls reference designs, validate new rack deployments, and support scaling of GB300 clusters while preserving control integrity.Provide technical leadership, training, and knowledge transfer to operations engineers/technicians on advanced controls topics: loop tuning methods, fault-tolerant design, data-driven optimization, and GB300-specific thermal control behaviors.Champion controls-focused continuous improvement: reduce mean time to recovery (MTTR) for thermal events, optimize energy/PUE via smarter loop control, and enhance sustainability through precise coolant management.QualificationsBachelor's degree in Controls Engineering, Electrical Engineering, Mechanical Engineering (with controls focus), Chemical Engineering, or related field (Master's preferred); equivalent experience in process/industrial controls considered.10+ years of experience in controls engineering/operations, with 5+ years in high-density data center environments, liquid cooling systems, or mission-critical thermal/process control (NVIDIA GB200/GB300, HPC, or similar ultra-dense GPU platforms strongly preferred).Deep expertise in control system design and operations for liquid cooling loops: PID tuning, cascade/override strategies, sequence control, VFD/pump/valve actuation, sensor fusion, and leak/pressure safety logic.Hands-on experience with rack-level or CDU controllers, embedded systems, PLCs (e.g., Siemens, Rockwell, Schneider), SCADA/BMS integration, and custom control software for thermal management.Proficiency in controls diagnostics tools, trending/analysis software, scripting (Python, ladder logic, structured text), and data-driven tuning/optimization.Proven ability to lead root cause investigations and implement robust corrective actions for control loop instabilities or failures in 24/7 critical environments.Strong understanding of thermal-fluid dynamics in closed-loop systems, coolant chemistry impacts on control, and high-reliability redundancy/failover strategies.Excellent problem-solving, communication, and leadership skills for mentoring teams in a fast-paced, high-stakes setting with on-call duties.Preferred SkillsDirect experience operating or optimizing controls for NVIDIA GB300 NVL72 or equivalent Blackwell Ultra liquid-cooled infrastructure.Familiarity with integrated controls frameworks (e.g., NVIDIA Mission Control interfaces, vendor CDU controllers) and data center-specific protocols.Background in advanced process control techniques (model predictive, adaptive) applied to cooling systems.","company":"Omniva","rawCompany":"omniva","city":"Houston","state":"TX","isRemote":false,"isActive":false,"createdAt":"2026-11-10T08:37:26.653Z","occupations":[{"code":"11-3051.01","title":"Quality Control Systems Managers","slug":"quality-control-systems-managers"},{"code":"17-2199.05","title":"Mechatronics Engineers","slug":"mechatronics-engineers"},{"code":"17-2071.00","title":"Electrical Engineers","slug":"electrical-engineers"}],"industries":[{"code":"541513","title":"Computer Facilities Management Services","slug":"computer-facilities-management-services"},{"code":"221330","title":"Steam and Air-Conditioning Supply","slug":"steam-and-air-conditioning-supply"},{"code":"333415","title":"Air-Conditioning and Warm Air Heating Equipment and Commercial and Industrial Refrigeration Equipment Manufacturing","slug":"air-conditioning-and-warm-air-heating-equipment-and-commercial-and-industrial-refrigeration-equipment-manufacturing"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Controls Operations Engineer","description":"As a Principal Controls Operations Engineer, you will be the senior technical authority for controls operations of NVIDIA GB300 (Grace Blackwell Ultra) liquid-cooled AI clusters in our Houston Data Center.
