Position Overview
We are seeking an experienced Building Automation / Facilities Controls Technician to support critical facility, utility, and HVAC systems in a highly regulated manufacturing environment. This role is focused exclusively on Siemens Building Automation Systems (BAS) and PPCL programming and is not a PLC programming position.
The site utilizes Siemens PXC BACnet controllers programmed in PPCL (Powers Process Control Language) to control HVAC, utilities, and facility systems that directly support manufacturing operations. Candidates must have hands-on Siemens BAS experience, including PPCL coding, troubleshooting, and system maintenance.
The primary objective of this role is to maximize facility and system reliability, prevent production interruptions, and continuously improve building and utility control systems.
Key Responsibilities
Work independently under the guidance of a supervisor or technical lead to support facility automation and controls systems
Perform daily monitoring, troubleshooting, and maintenance of Siemens BAS-controlled systems
Write, modify, and troubleshoot PPCL code for Siemens PXC controllers
Support HVAC, utility, and facility systems including air handlers, chillers, and related infrastructure
Identify control system issues and implement corrective actions to prevent production downtime
Assist operations and engineering teams in troubleshooting system issues and assessing potential impacts to production
Participate in the design, improvement, and optimization of facility and control systems
Support start-up of new systems and troubleshooting of existing facilities and equipment
Maintain system documentation, monitoring logs, Best Operating Practices (BOPs), and training materials for regulatory compliance
Recommend improvements related to system design, installation, start-up, and long-term maintenance strategies
Exchange technical information with engineers, project teams, management, contractors, and outside consultants
Ensure compliance with applicable safety, regulatory, and company policies and procedures
Required Qualifications
Hands-on experience with Siemens Building Automation Systems (BAS)
Strong PPCL coding experience (writing, modifying, and troubleshooting)
Experience working with Siemens PXC BACnet controllers
Siemens Apogee Insight
Siemens Desigo
Strong knowledge of HVAC systems and facility controls (air handlers, chillers, utilities, etc.)
Solid understanding of HVAC sequences of operation
Minimum 5 years of relevant technical experience supporting facility or building automation systems
High School Diploma or GED required
Technical school certification or completion strongly preferred
Working knowledge of basic regulatory requirements in a manufacturing or regulated environment
Important Notes (Must Read)
This is a Building Automation / Facilities Controls role — NOT a PLC role
PLC programming experience alone will not translate to this position
PPCL is a proprietary Siemens BAS language used exclusively with Siemens PXC controllers
The site does not use PLCs for Siemens controls
Manufacturing systems depend on BAS-controlled facilities and utilities, requiring high reliability and attention to detail
