About the role
Senior role focused on owning and developing controls standards, architectures, and integration for mechanical systems in Lambda’s large-scale AI data centers, with emphasis on control narratives, sequences of operation, and cross-team coordination.
Responsibilities
- Own controls standards and reference architectures for mechanical systems supporting large-scale AI data centers.
- Develop control narratives, sequences of operation, points lists, alarm matrices, cause-and-effect diagrams, and controller requirements.
- Define automation for central cooling plants, heat-rejection systems, pumps, heat exchangers, CRAHs, CDUs, liquid-cooling loops, valves, and associated equipment.
- Design system behavior for startup, shutdown, maintenance, component failure, utility loss, and recovery.
- Establish requirements for sensors, actuators, meters, control panels, PLCs, DDC controllers, gateways, and operator interfaces.
- Define BMS integration, mechanical telemetry, trending, alarming, data retention, and interfaces with other operational systems.
- Review partner designs, vendor submittals, control drawings, network architectures, and equipment packages for compliance with Lambda standards.
- Coordinate controls requirements across mechanical, electrical, network, hardware, construction, commissioning, and operations teams.
- Support factory testing, site acceptance testing, commissioning, integrated systems testing, and cooling-system bring-up.
- Troubleshoot control-loop instability, sensor errors, communication failures, nuisance alarms, and sequence deficiencies.
- Incorporate commissioning results and operating lessons into future designs and control standards.
- Travel to project sites, manufacturers, and partner facilities as needed.
Qualifications
- Have experience designing or commissioning mechanical controls for data centers, mission-critical facilities, central plants, or industrial environments.
- Understand chilled-water, condenser-water, heat-rejection, air-cooling, and liquid-cooling systems.
- Can develop and review sequences of operation, P&IDs, control diagrams, wiring diagrams, points lists, and functional test procedures.
- Understand PLC, DDC, and BMS architectures and common protocols such as BACnet, Modbus, and OPC UA.
- Have experience with instrumentation, sensor selection, control loops, alarms, interlocks, and equipment safeties.
- Understand how mechanical systems should respond during equipment failures, power events, and changing thermal loads.
- Can translate operational requirements into clear, testable control behavior.
- Communicate effectively with engineers, programmers, vendors, commissioning teams, and facility operators.
- Hold a bachelor’s degree in mechanical, electrical, controls, or systems engineering, or equivalent practical experience.
