Senior Process Engineer

Senior Process Engineer

We are seeking a highly skilled and motivated Senior Process Engineer to join our Technology Team. This position serves as a critical technical resource bridging the Technology Team's process design capabilities with the operational needs of our Sulfuric Acid and Spent Acid Regeneration (SAR) manufacturing network. The successful candidate will be an experienced chemical engineer with a deep passion for process design, rigorous technical problem-solving, and a proven ability to drive projects from concept through execution.

This role operates with a broad mandate — developing and owning front-end process designs, scoping capital and improvement projects, and providing expert-level technical support to plant operations across our UPA and SPPC Spent Acid site network. The ideal candidate thrives in an environment where they can pivot between deep technical analysis and hands-on plant engagement.

Qualifications

• Proven ability to scope and lead engineering projects from concept through implementation
• Strong technical troubleshooting skills with the ability to diagnose complex process issues and drive resolution
• Ability and willingness to travel to plant sites as needed (estimated 20–40%)
• Excellent written and verbal communication skills for technical and non-technical audiences

Strongly Preferred Qualifications

• Sulfuric acid plant experience (contact process, double absorption, SO₂ handling, converter operations, acid towers/absorbers) — strongly preferred
• Spent acid regeneration (SAR) process experience — a significant plus
• Proficiency in Aspen Plus and/or Aspen HYSYS — strongly preferred
• Experience with HAZOP/PHA facilitation and MOC processes
• Capital project development experience (AACE cost classes, FEED studies, project scoping)
• Prior experience in a technology center, R&D, or corporate engineering function is desirable

Work Environment & Physical Requirements

Position may be based at a UPA site (Tulsa, OK; Riverton, WY; Cairo, OH) or an SPPC Spent Acid Regeneration site (Beaumont, TX; Anacortes, WA; Richmond, CA; Toledo, OH) although a remote option will be considered with significant sulfuric acid experience.

Must be comfortable working in both office/laboratory environments and industrial plant environments, including exposure to heat, noise, and chemical processing areas

Must be physically able to perform plant walkthroughs, climb stairs and ladders, and conduct field inspections in PPE-required environments

Travel to other company sites, conferences, and vendor/contractor facilities will be required

Responsibilities

• Process Design & Engineering
• Project Scoping & Execution Support
• Technology Development & Knowledge Management
• Plant Technical Support & Troubleshooting
