Ecovyst Process Engineering Role
Backed by an over 130-year history, Ecovyst has evolved into a platform of leading sulfur solutions united by a shared commitment to reliability, innovation, and performance. We have carefully cultivated our reputation as a premier provider of virgin sulfuric acid, sulfuric acid regeneration services, and sulfuric acid derivatives. We provide specialty grade high-purity virgin sulfuric acid for a number of diverse and growing end uses.
Among them are mining, particularly copper for electronics applications, production of electric vehicles and the ongoing expansion of data centers across the globe, and industrial applications including our customers' production of nylon precursors, production of lead acid batteries for all types of vehicles, industrial and municipal water treatment, and refining and petrochemical processes.
Ecoservices provides sulfuric acid regeneration, produces virgin sulfuric acid, and offers chemical waste handling and treatment services. Calabrian produces high-value sulfur dioxide and derivative solutions, enabling us to serve a broader set of essential industries. Chem
32 sulfides and activates catalysts for refining and renewable fuel processes.
What we offer:
- Competitive pay
- Full benefit package
- 401k matching
- Tuition Reimbursement
Serve as the primary process engineering resource embedded within the production operation provide day-to-day process engineering support to the Production Supervisor and operating team for troubleshooting, process optimization, and unit performance improvement.
What you will be doing:- Monitor and analyze process data using OSIsoft PI Vision — track key process variables (temperatures, pressures, flows, concentrations, conversion efficiency) across all production units; identify trends, deviations, and developing issues; generate process performance summaries and reports for the Production Supervisor and Operations Manager.
- Provide production troubleshooting support — assist the Production Supervisor and operators in diagnosing process upsets, off-spec production, equipment deviations, and unit inefficiencies; develop and communicate corrective operating guidance; participate in post-event reviews and document learnings.
- Own MDC (Maximum Daily Capacity) testing and debottlenecking — design and execute MDC tests in coordination with the Production Supervisor; analyze test results; identify process and operational constraints that limit throughput; develop and implement operating recommendations to maximize production to MDC rate; document results and track improvement actions.
- Own VMC (Variable Manufacturing Cost) oversight — monitor and track variable manufacturing cost drivers per ton of acid produced including water, electricity, Mag Hydroxide, and sulfur/spent acid feed ratios; compare actual usage to budget targets; identify deviations and opportunities to reduce operating costs; develop and implement operating changes to improve VMC efficiency; report VMC performance to Operations Manager on a regular cadence.
- Participate actively in PHAs and the site PHMP (Process Hazard Management Program) — serve as an active technical contributor in all PHA and HAZOP reviews per the PHMP revalidation schedule; ensure current operating conditions, known deviations, and production constraints are accurately represented in hazard scenarios; track and drive closure of PHA action items assigned to the operations function in Enablon; support accurate maintenance of PHMP documentation.
- Support the MOC (Management of Change) process for operational and process changes — provide process engineering review and technical input on MOCs affecting production operations; assist with documentation and training coordination.
- Own and maintain standard operating procedures (SOPs) for assigned production units — ensure procedures accurately reflect current operating conditions, approved operating limits, and best practices; initiate MOCs for any required procedure revisions.
- Support production KPI tracking and reporting — assist in developing and maintaining production dashboards covering OEE, MDC rate, VMC, and SUMO status;…
