[Hiring] Director of Building Management System Design @Nscale

Role Description

This role owns the design and technical integrity of the Building Management System (BMS) and Electrical Power Monitoring System (EPMS), including the PLC-based SCADA architecture built on Ignition, per Nscale's standardized PLC/SCADA control architectures.

You'll operate at the intersection of mechanical engineering, automation, and commissioning, working closely with:

• Internal controls engineers
• Mechanical designers
• OEMs
• Skid manufacturers
• System integrators
• Field commissioning teams

You'll author and own Nscale's standard library of control sequences and points lists: a Sequence of Operations (SOO) and a matching points list for every type of mechanical and electrical equipment and system deployed in a North America facility.

This is a senior individual contributor role that carries design authority. You'll set the standard, hold design consultants, OEMs, and system integrators to it through:

• Submittal review
• Factory testing
• Commissioning

What You'll be Doing

• Standard SOO Library: Author, own, and maintain the standard Sequence of Operations for every equipment type and system deployed in an Nscale facility.
• Standard Points Lists & Data Model: Own the standard points list, naming, and tagging convention for each equipment type.
• P&ID Development: Develop, review, and own P&IDs for mechanical and electrical systems.
• BMS & Mechanical Controls Design: Serve as the primary controls SME for datacenter cooling systems.
• EPMS & Electrical Monitoring Design: Define metering topology, breaker and switchgear status monitoring, and alarm hierarchy.
• Vendor, OEM & System Integrator Management: Define required control interfaces and review integrator programming submittals.
• Risk, Reliability & Commissioning: Participate in FMEA sessions and design reviews.
• Documentation & Standards: Ensure BMS, EPMS, and SCADA designs comply with Nscale OT network standards.

Qualifications

• Bachelor's degree in Mechanical Engineering, Electrical Engineering, Controls/Automation Engineering, or a related discipline.
• 10+ years of experience in industrial controls, building automation, or SCADA engineering.
• Demonstrated experience authoring Sequences of Operation and points lists.
• Deep experience with PLC-based SCADA systems.
• Demonstrated experience developing P&IDs for mechanical and/or electrical systems.
• Strong command of integration protocols and industrial networking.
• Strong understanding of datacenter cooling systems.
• Strong communication skills across mechanical, electrical, controls, IT, and operations disciplines.

Nice to Have

• Professional Engineer (P.Eng/PE) license.
• Experience developing controls standards or a sequence library for a multi-site portfolio.

Why this role matters

A standard library of Sequences of Operation is one of the highest-leverage controls deliverables Nscale can own. It converts control behavior from a per-project negotiation into a specified, reusable standard.

Benefits

• Highly competitive package (base + equity) with reviews every 12 months.
• Join the fastest-growing tech startup with opportunities to push boundaries.
• Dynamic progression plan tailored to your ambitions.
• Human-First Flexibility: A flexible workplace that trusts Nscalers to deliver.
