Data Center Facility Telemetry & Controls Engineer

Responsibilities

• BMS / Controls Architecture & Integration
• Architect and manage BMS integration across colocation and Lambda-owned facilities, covering chillers, CRAHs, CDUs (Coolant Distribution Units), cooling towers, UPS systems, PDUs, and automatic transfer switches.
• Define standards for BMS point lists, naming conventions, control sequences, and integration protocols (BACnet, Modbus, SNMP, OPC-UA, RESTful APIs).
• Oversee commissioning and acceptance testing of new BMS deployments and CDU/TCS loop integrations for next-generation liquid-cooled GPU rack systems.
• Collaborate with colocation partners (Equinix, Digital Realty, and others) to ensure telemetry data flows from provider BMS/EPMS into Lambda's monitoring stack.
• DCIM & Telemetry Platform Management
• Own the DCIM platform strategy and roadmap - evaluating, selecting, and implementing tooling for asset management, capacity planning, environmental monitoring, and power chain visibility.
• Develop and maintain real-time dashboards for PUE, thermal performance, stranded capacity, and cooling system efficiency across all Lambda sites.
• Build and maintain telemetry pipelines ingesting data from BMS, PDUs, in-rack sensors, CDUs, and network devices into centralized monitoring and alerting platforms (e.g., Prometheus, Grafana, InfluxDB, or equivalent).
• Define alarm thresholds and escalation workflows for critical facility events including high coolant temperatures, CDU inlet/outlet anomalies, leak detection, and power exceedances.
• Liquid Cooling Controls & High-Density Operations
• Develop control strategies and setpoint frameworks for TCS (Thermal Control System) loops supporting direct liquid cooling at densities of 220-380 kW per rack.
• Evaluate and qualify CDU vendors on controls integration capabilities, telemetry exposure, and remote management interfaces.
• Define and enforce operational procedures for CDU commissioning, setpoint changes, loop pressure management, and fluid quality monitoring.
• Support design and construction coordination for liquid cooling infrastructure in new data center buildouts, ensuring BMS and controls readiness at Day 1.
• Operational Reliability & Incident Response
• Establish and maintain facility event management processes, including on-call response protocols for facility telemetry anomalies.
• Lead root cause analysis for facility system failures and implement corrective actions to prevent recurrence.
• Partner with the data center operations team to maintain and refine emergency response runbooks tied to BMS alerts and automated controls.
• Drive continuous improvement in MTTR for facility-related events through better telemetry coverage and automated remediation.
• Vendor & Stakeholder Management
• Manage BMS integrators, DCIM vendors, and control subcontractors - from RFP through design, installation, commissioning, and ongoing support.
• Serve as the primary technical interface with colocation providers on all BMS/EPMS integration topics.
• Collaborate with Lambda's infrastructure engineering, construction, and procurement teams to align controls requirements with facility buildout timelines.
• Support due diligence and technical evaluation for new colocation sites and modular data center deployments from a telemetry and controls readiness perspective
• You
• Required Experience
• 7+ years of experience in data center infrastructure engineering, with at least 4 years focused on BMS, DCIM, or controls systems in a hyperscale, colocation, or AI/HPC environment.
• Hands-on experience designing and integrating BMS for mission-critical facilities including UPS, PDU, CRAH/CRAC, chiller plant, cooling tower, and liquid cooling (CDU/in-row) systems.
• Strong working knowledge of industrial control protocols: BACnet IP/MS-TP, Modbus TCP/RTU, SNMP, DNP3, and modern API-based integrations.
• Demonstrated experience with DCIM platforms (Nlyte, Sunbird, Vertiv TRELLIS, or equivalent) inc
