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
