Phillips 66 & YOU - Together we can fuel the future
As a Sr Engineer I, Advanced Process Control (APC) Engineer , you will help optimize complex refining processes through innovative control solutions. You will join a collaborative Process Engineering team that partners closely with various teams to safely maximize unit performance, reliability, and margin. In this role, you will work independently and provide guidance on APC strategies that keep our refinery running safely, efficiently, and competitively.
What You'll Do

Lead the design, implementation, tuning, and optimization of advanced process control (APC) applications to improve refinery unit stability, throughput, and yields, using Honeywell Forge APC and related tools.

Design and refine process control strategies and equipment specifications for capital and expense projects, defining instrumentation and control strategy requirements related to APC.

Create and maintain APC documentation, standards, safe work practices, and training materials for operators and technical staff; lead Management of Change (MOC) and periodic audits for APC applications.

Analyze process and APC data to identify improvement opportunities, recommend new technical developments, and quantify benefits in terms of energy use, margin, and reliability.

Lead or contribute to small and medium APC projects from concept through startup, coordinating with multi-functional teams and vendors to deliver on scope, schedule, and cost.

Provide technical guidance and mentoring to less experienced APC and process engineers while continuously building your own expertise in emerging APC technologies and best practices.
