About the Role
We are seeking an experienced Software Engineer specializing in mission-critical environments such as data centers. This role focuses on programming, integrating, and optimizing Building Management Systems (BMS) and Environmental Controls across platforms like Distech/Niagara, Siemens Desigo, Johnson Controls Metasys, and other industry leaders. You will ensure high reliability, redundancy, and compliance with stringent uptime requirements.
 

Key Responsibilities

Programming & Configuration

• Develop and deploy control logic for Distech EC-Net/Niagara N4, Siemens Desigo CC, JCI Metasys, and similar platforms.
• Implement advanced Sequences of Operation for critical cooling systems (CRAC/CRAH units, chillers, economizers, UPS/HVAC integration).
• Configure graphics, alarms, and trending dashboards optimized for 24/7 monitoring.

Data Center-Specific Integration

• Integrate BMS with critical infrastructure systems: cooling towers, generators, UPS, PDUs, and electrical switchgear.
• Ensure redundancy and failover logic for HVAC and environmental controls.
• Support DCIM (Data Center Infrastructure Management) integration and API-based data exchange.

Networking & Cybersecurity

• Configure BACnet/IP, Modbus TCP, and secure Niagara stations with TLS certificates.
• Implement VLAN segmentation, BBMDs, and firewall rules for OT networks.
• Apply cybersecurity best practices for remote access and compliance with SOC 2, ISO 27001, or client-specific standards.

Testing & Commissioning

• Perform Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) for mission-critical systems.
• Validate redundancy, alarm escalation, and fail-safe sequences under simulated failure conditions.

Documentation

• Maintain detailed IO lists, point databases, and as-built drawings.
• Provide compliance documentation for ASHRAE, Uptime Institute Tier standards, and client SLAs.

Qualifications
Required

• 5+ years programming BMS for mission-critical facilities (data centers, large-scale IT environments).
• Expertise in Distech/Niagara N4, Siemens Desigo, and JCI Metasys.
• Strong understanding of BACnet, Modbus, and IP networking fundamentals.
• Experience with redundant cooling systems, CRAC/CRAH units, and chiller plant optimization.
• Ability to work remotely with occasional site visits for commissioning.

Preferred

• Familiarity with DCIM platforms (e.g., Schneider EcoStruxure IT, Nlyte).
• Niagara N4 certification, Siemens Desigo, or JCI Metasys credentials.
• Knowledge of ASHRAE TC9.9 guidelines for data center cooling.

Tools & Tech

• Platforms: Distech EC-Net/Niagara N4, Siemens Desigo CC, JCI Metasys, Schneider EcoStruxure
• Protocols: BACnet/IP, Modbus TCP, SNMP (for IT integration)
• Networking: VLANs, BBMDs, VPN, TLS certificates
• Critical Systems: CRAC/CRAH, chillers, UPS, generators, PDUs
