Nscale enables AI-focused companies to achieve superior results by reducing the complexity of AI development. Our GPU cloud bolsters technical capabilities and directly supports strategic business outcomes, including cost management, rapid innovation, and environmental responsibility. We thrive on a culture of relentless innovation, ownership, and accountability, where every team member takes pride in their work and drives it with excellence and urgency.

As an Nscaler, you'll build trust through openness and transparency, where everyone is inspired to do their best work. If you join our team, you'll be contributing to building the technology that powers the future.

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, and field commissioning teams to ensure equipment integrates seamlessly into Nscale's BMS and EPMS environments and supports scalable, repeatable deployments.

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. You'll maintain a governed, versioned, reusable set of sequences and points lists that every project, vendor, and integrator is designed and built to, making control behavior deterministic, comparable, and repeatable across a growing portfolio.

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, and commissioning, and work directly with mechanical, electrical, CSA, construction, commissioning, and Operations teams to make sure what gets built matches what was specified.

• ** Standard SOO Library.
  ** Author, own, and maintain the standard Sequence of Operations for every equipment type and system deployed in an Nscale facility, including chilled water plants, CDUs and liquid cooling, chillers, dry coolers, CRAH/CRAC units, air handling and ventilation, pumping systems, humidification, leak detection, generators, UPS, switch gear and ATS, and building-level systems.
• ** Standard Points Lists & Data Model.
  ** Own the standard points list, naming, and tagging convention for each equipment type, including per-point attributes such as signal type, units, range, alarm limits, and historian requirements.
• ** P&t.
  ** Develop, review, and own P&IDs for mechanical and electrical systems, keeping sequences, points lists, and P&IDs as one coherent, version-controlled design set.
• ** BMS & Mechanical Controls Design.
  ** Serve as the primary controls SME for datacenter cooling systems including CDUs, chillers, dry coolers, CRAH/CRAC units, and direct-to-chip liquid cooling skids.
• ** EPMS & Electrical Monitoring Design.
  ** Define metering topology, breaker and switch gear status monitoring, power quality capture, and alarm hierarchy across the electrical distribution chain.
• ** Vendor, OEM & System Integrator Management.
  ** Define required control interfaces, issue Nscale sequences and points lists as the binding technical basis for vendor scope, and review integrator programming submittals.
• ** Risk, Reliability & Commissioning.
  ** Participate in FMEA sessions and design reviews, and own controls scope through HAT, FAT/CAT, SAT, and integrated systems testing.
• ** Documentation & Standards.
  ** Ensure BMS, EPMS, and SCADA designs comply with Nscale OT network standards, and drive continuous improvement of controls design standards based on field performance.

• 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, including significant experience in mission-critical or industrial environments (datacenters strongly preferred).
• Demonstrated experience authoring, not merely reviewing,…
