Key Responsibilities

Review, test, and support implementation of DCS, SIS, HMI, SCADA, and related control-system

application changes.

Integrate project deliverables into the er Automation and Control System in accordance with

approved procedures, specifications, and cybersecurity requirements.

Support Honeywell Experion/C300 and Triconex-based systems, orparable industrial control and

safety platforms.

Review and interpret P&IDs, cause-and-eAect diagrams, shutdown narratives, control narratives,

system requirements, I/O lists, logic diagrams, alarm requirements, graphics, and instrument

documentation.

Coordinate configuration and data validation for analog and digital I/O, controllers, remote I/O, logic

solvers, junction boxes, networks, HMI graphics, SCADA points, alarms, and operator interfaces.

Participate in and support FAT, software testing, SAT, loop checks, functional testing, SIS testing,

startup,missioning, and post-installation verification.

Verify that SIS logic, interlocks, permissive, trips, bypasses, alarms, and final-element responses

match approved project and process-safety requirements.

Support alarm configuration and validation in accordance with approved alarm-response

assessments, critical-alarm requirements, site standards, and project documentation.

Develop, maintain, and execute installation, test, checkout, cutover, andmissioning procedures.

Manage technical questions, field discrepancies, punch-list items, redlines, as-built updates, and

turnover documentation throughpletion.

Support configuration backup, version control, document control, and traceability of approved system

files and changes.

Follow site requirements for cybersecurity, virus-free file verification, access control, media handling,

and transfer of project files to the Automation and Control System.

Identify technical, schedule, interface, constructability, and operability risks andmunicate

mitigation needs to the project team.

Provide field and startup support during planned maintenance windows, turnarounds, and project

execution activities, including occasional extended or oA-shift coverage when required by the work

scope.

Promote safe work practices, process safety, management-of-change discipline, andpliance with

applicable Phillips 66 procedures and standards.

Required Qualifications

Demonstrated experience integrating, configuring, testing,missioning, or maintaining industrial

DCS and SIS applications.

Experience working in refining, petrochemical, chemical, power, or another process-industry

environment.

Working kledge of control-system engineering and implementation documentation, including I/O

lists, cause and eAects, control narratives, shutdown narratives, logic diagrams, alarm requirements,

and HMI graphics, marshalling and termination drawings. Experience supporting FAT, SAT, loop checks, functional testing,missioning, startup, or control

system cutover activities.

Ability to troubleshoot control-system, instrumentation,munication, and application issues in a

structured and safety-focused manner.

Ability to read and technical specifications, approved procedures, P&IDs, electrical and

instrument drawings, and vendor documentation.

Strong written and verbalmunication skills, with the ability to coordinate across Operations,

Maintenance, Engineering, Construction, vendors, and contractors.

Ability to work independently, manage priorities, and document technical decisions and field results.

Willingness to work at an operating refinery, including field assignments and occasional oA-hours

support when required.

Preferred Qualifications

Experience with Honeywell Experion PKS, C300, Honeywell

TPS, TDC

3000, Triconex, orparable

DCS/SIS platforms.

Experience with DCS/SIS migration, modernization, brownfield integration, remote I/O, electronic

marshaling, SCADA, HMI, or control-network interfaces.

Familiarity with SIS lifecycle activities, safety requirements specifications, SIL concepts, LOPA/PHA

interfaces, interlock testing, proof-test requirements, and bypass management.

Experience developing or reviewing installation procedures, FAT/SAT plans, test scripts,missioning procedures, turnover packages, and punch-list closure documentation.

Kledge of industrial control-system cybersecurity practices and process-control-network access

controls. Experience supporting turnaround planning, hot cutovers, cold cutovers, or staged control-system

installations.
