Energy Systems Architect

ENERGY SYSTEMS ARCHITECT- PHILADELPHIA, PA (REMOTE)
The Select Group’s Telecommunication vertical is seeking an Energy Systems Architect. In this role, the Architect will act as the technical lead for the energy and microgrid layer of a Virtual Building Automation System (VBAS) program. They will design and validate the microgrid simulation platform, define the digital twin architecture, and lead the AWS-hosted platform architecture. This is a senior individual contributor role requiring deep power systems engineering knowledge paired with AWS IoT, digital twin, and modern data engineering skills. There is a strong preference for candidates local to the New Jersey, New York City, Maryland, Delaware, Virginia, or Connecticut areas for occasional onsite meetings in Philadelphia; however, the role is otherwise open to remote candidates.

What You'll Bring:

• 7+ years in power systems engineering, energy storage, or microgrid design 
• Hands-on experience with SCADA/BMS protocols: BACnet/IP, BACnet MS/TP, Modbus TCP/RTU, OPC-UA, DNP3, or IEC 61850 
• Experience with digital twin or simulation platforms: GridLAB-D, HOMER Pro, MATLAB/Simulink, or AWS IoT TwinMaker 
• Familiarity with DER assets: UPS systems, battery storage, generators, demand response programs, and curtailment programs 
• AWS IoT services depth: SiteWise, IoT Core, IoT Greengrass, IoT TwinMaker (or equivalent cloud IoT platform experience with willingness to adopt AWS) 
• Ability to produce IEEE/ANSI-aligned architecture documentation and one-line diagrams 
• Experience integrating with cloud data pipelines: REST APIs, MQTT (mTLS with X.509 device certificates), and managed time-series storage (Amazon Timestream, InfluxDB, or Historian) 
• Bachelor's degree in Electrical Engineering, Power Systems, or related; PE license a strong plus 

• Experience with critical facility, large-scale datacenter, or telecom headend infrastructure 
• Knowledge of ASHRAE A2 thermal thresholds and critical facility cooling systems 
• Familiarity with Amazon Managed Grafana or operational dashboarding tools 
• Experience with California 72-hour battery backup mandate or similar utility resiliency requirements 
• Familiarity with NERC CIP or NIST SP 800-82 (Operational Technology security) 
• NABCEP, CEM, or LEED credentials 

• Design and document the microgrid simulation architecture: DER topology, BMS/SCADA integration points, data flows, and AWS service mapping (AWS IoT SiteWise for asset modeling; AWS IoT TwinMaker for digital twin scenes; SageMaker for simulation compute) 
• Define simulation parameters: charge/discharge cycles, depth of discharge, curtailment triggers, peak-load dispatch logic, and AI-load surge thresholds 
• Lead the digital twin calibration process against historical actuals; own the +/-5% accuracy validation target across six scenarios (peak demand curtailment, battery-first dispatch, generator failover, AI-load surge, demand response participation, time-of-use arbitrage) 
• Establish the shared data lake schema in coordination with Data Engineers; ensure the schema supports both energy simulation and HVAC automation use cases 
• Design the national three-tier platform architecture (Tier 1 site collectors, Tier 2 regional analyzers, Tier 3 national platform) and CMDB baseline supporting expansion to the full footprint 
• Serve as platform architecture authority for VBAS national operations, SLA governance, and use case registry growth 
• Provide BMS/SCADA API advisory to the HVAC/BAS Integration Engineer on the controller integration layer 
• Coordinate with the AWS Solutions Architect on AWS service selection, landing zone validation, and Pro Services engagement 
• Produce architecture documentation, topology diagrams, one-line electrical diagrams, and integration specifications for review
