Summary

Position Tittle: OT System Integration Engineer
Location: Remote (Strongly preferred location in Tri State area to come into Downingtown office as needed
Duration: Long Term
 
Job Details:

The OT System Integration Engineer is the controls specialist who designs and implements the Virtual Building Automation System (VBAS) automation logic at Comcast facilities. They build the stage-up and stage-down automation sequences that respond to thermal and electrical threshold triggers, integrate with existing HVAC controller interfaces from Eaton, Siemens, Liebert (Vertiv), and other vendors, and implement the safety interlock and manual override framework. The VBAS POC operates at two Downingtown pilot sites in Recommend Mode (operators approve every recommended action; no autonomous execution until a separate Change Order is approved). This role requires deep HVAC controls engineering knowledge with hands-on familiarity with industrial protocols (BACnet/IP, BACnet MS/TP, Modbus TCP, OPC-UA), and is supported by AWS IoT Greengrass v2 and SiteWise Edge for protocol translation at the edge. The integration engineer works as part of the joint Comcast/AWS/TSG team.

Must Have Skills:

5+ years in HVAC controls engineering or building automation systems integration. 
Programming experience with industrial protocols. Hands-on experience designing programs that integrate via BACnet/IP, BACnet MS/TP, Modbus TCP, Modbus RTU, OPC-UA, or LON (read and write configuration). 
Automation logic programming. Experience designing, developing, and modifying automation logic programs in BAS platforms: Johnson Controls Metasys, Siemens Desigo CC, Schneider EcoStruxure, Honeywell, or equivalent. 
Knowledge of ASHRAE A2 thermal environment specifications for data centers or critical facilities. 
Field commissioning experience — must be comfortable on-site at live operating facilities. 
Ability to interpret HVAC drawings, sequence of operations, and control panel documentation. 
Edge gateway programming. Familiarity with edge gateway concepts; AWS IoT Greengrass v2 component program experience preferred (willingness to adopt is acceptable). 

 

Nice to Have Skills:

Experience with Comcast, co-location, telecom headend, or hyperscaler datacenter facility environments. 
Familiarity with AWS IoT SiteWise Edge or equivalent industrial cloud gateway programs. 
Experience designing programs for AI/ML-driven automation platforms or predictive control systems. 
Familiarity with Eaton Foreseer or vendor-specific monitoring platforms in the Comcast footprint. 
Python programming for automation logic test programs or API integration programs. 
Knowledge of NIST SP 800-82 (Operational Technology security) or Purdue Model network segmentation. 
Certified Control Systems Technician (CCST) or equivalent credential. 
Experience with containment systems: hot-aisle/cold-aisle containment, in-row cooling. 

Day to day responsibilities: 

Automation logic program design and development. Apply systems analysis techniques to determine functional specifications; design, develop, document, test, and modify stage-up and stage-down automation logic programs based on ASHRAE A2 thermal thresholds and electrical load signals. 
Integration program development. Design and modify integration programs connecting the automation control logic with existing HVAC controller interfaces using BACnet/IP (primary), BACnet MS/TP (legacy serial), Modbus TCP/RTU, OPC-UA (preferred for newer systems), or vendor-specific APIs from Eaton, Siemens, Liebert, and Foreseer. 
Edge component program deployment. Design, develop, document, deploy, and modify AWS IoT Greengrass v2 component programs at site for protocol translation and local buffering during connectivity loss. 
SiteWise Edge gateway configuration program. Design and modify AWS IoT SiteWise Edge gateway configuration programs to consume facility telemetry via BACnet, Modbus, and OPC-UA connectors. 
Safety interlock program implementation. Design, develop, test, and modify safety interlock programs: manual override capability, minimum cycle time enforcement, alert escalation, override audit trail. 
POC execution and program validation. Execute the HVAC Automation POC at the two Downingtown pilot sites in Recommend Mode with the Comcast facilities team supervising every recommendation; analyze program output and modify automation programs based on operator feedback. 
POC results analysis and documentation. Document POC results: response latency, setpoint accuracy, false-positive rate, operator feedback, PUE and EPCB outcome metrics against pre-POC baseline. 
Automation sequence validation. Validate automation sequence programs against Comcast-approved operating parameters; coordinate vendor support engagements (Eaton, Siemens, Liebert) where controller access requires vendor configuration. 
Test program collaboration. Support the QA/Integration Analyst during test execution; analyze test results and design corrective program modifications. 
Specification documentation. Produce automation logic program specifications, control flow diagrams, and commissioning documentation.
