Job description

Senior Controls Solutions Senior Engineer (U.S.)

Department: Controls & Electrical / Data Center & OEM Solutions

Location: U.S. (hybrid; travel as required)

Date: January 28, 2026

Reports To: Director, Engineering & Controls (U.S.)

Position Summary

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.

Key Responsibilities

• 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.
• 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.

Minimum Qualifications

• 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.
• OTD ≥ 95% for controls deliverables (SOO, code, drawings) to production/commissioning gates.
• Bench-Found Defects ≥ 80% of total defects (shift-left) and Commissioning Punchlist ↓ 30–50% vs. baseline.
• Parts EoL Zero Surprise Events on released programs (alternates qualified ≥ 1 per critical component).
