Controls Solutions Senior Engineer (U.S.)

Own the end-to-end controls architecture and delivery quality for FläktGroup’s air-side and liquid-side OEM platforms and data-center solutions in the U.S. market. This role is the technical authority (SME) for Sequence of Operation (SOO) design, code development & review, controls parts logistics support, new integrations (BMS/protocols/devices), and drawing/version governance-from design through FAT/SAT/IST, handover, and warranty support. Lead standards, guide cross-functional teams, and serve as customer-facing engineering leadership at critical milestones., Controls Architecture & Standards Ownership

• Define and maintain the primary controls architecture for U.S. air-side and liquid-side platforms, including CRAH, CRAC, FWU, and CDU systems.
• Establish modular code libraries, naming conventions, and safety interlocks to ensure repeatable product quality across all plants.
• Design and maintain mission-critical redundancy logic (N+X configurations) and automatic failover sequences to ensure 100% uptime for data center cooling infrastructure.
• Govern the integration of high-speed sensors, drives, and controllers, ensuring full interoperability across BACnet, Modbus, and third-party APIs.

SOO Development & Release Governance

• Translate system-level sequences into production-grade SOO code while enforcing strict peer code reviews and testing standards.
• Develop specialized “Fast Start” and “Rapid Restart” sequences to minimize thermal spikes in the data hall following power interruptions.
• Engineer dedicated control logic for leak detection, containment, and isolation specifically for liquid-side CDU and FWU platforms.
• Manage global revision control, including versioning, change logs, and rollback plans for all platform-specific and job-specific code derivatives.

Hardware Validation & Test Bench Leadership

• Architect and lead hardware-in-the-loop (HIL) simulated test benches to validate logic, I/O mapping, and fail-safes prior to factory release.
• Define rigorous pass/fail certification gates and testing protocols to maximize “shift-left” defect detection.
• Ensure high-frequency telemetry support for integration with Data Center Infrastructure Management (DCIM) and environmental monitoring platforms.

Technical Documentation & Drawing Governance

• Govern version control for all electrical/controls drawings, I/O lists, wiring diagrams, P&IDs, and panel schedules.
• Maintain absolute traceability between customer requirements, SOO design, released code, and final FAT/SAT documentation.
• Partner with Supply Chain to qualify and sustain approved controls components, proactively managing alternates and end-of-life (EoL) risks.

Project Execution & Customer Leadership

• Lead technical authority for Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), and Integrated Systems Testing (IST).
• Serve as the top-tier subject matter expert (SME) for troubleshooting complex site escalations involving controls logic or system performance.
• Own technical reviews with customers regarding design intent, integration strategy, and commissioning readiness.
• Provide structured feedback to Product Engineering to refine hardware selection and improve commissioning efficiency based on field learnings.

• B.S. in Electrical, Controls, Mechanical (with strong controls), or related Engineering.
• 7+ years in HVAC/BAS controls with hands-on DDC/PLC programming, commissioning, and BMS integration (BACnet IP/Modbus).
• Proven ownership of architecture, code reviews, and release/version control.
• Experience leading FAT/SAT/IST and resolving complex field issues.

Preferred Qualifications

• Data-center or mission-critical cooling experience; redundancy and fail-safe strategies.
• Experience with hardware-in-the-loop test setups and automated test frameworks.
• Familiarity with ERP/MRP signals for parts availability and alternates.
• Exposure to cybersecurity considerations for BAS/OT networks.

Tools & Platforms

• DDC/PLC environments (BACnet/Modbus-capable controllers; function block/structured text IDEs).
• Electrical CAD and revision control tools (e.g., AutoCAD Electrical + PDM/PLM or Git-like DMS).
• Protocol analyzers, simulators, and HIL bench equipment.
