Role Overview
The Senior Process Engineer will own the process engineering scope for M2X’s bio-methanol and RNG facilities across the full asset life cycle — site and process design, commissioning and startup, day-to-day operations support, and ongoing performance improvement. This individual will be the technical authority on gas conditioning, separation, and conversion unit operations: developing and maintaining PFDs, P&IDs, and heat and material balances; running simulations to evaluate design and off-design cases; troubleshooting alongside operators in the field; and identifying and executing improvements in methane recovery, yield, uptime, and safety. The ideal candidate is a hands-on chemical engineer who is equally comfortable in a simulation file, a HAZOP session, and a control room at 2 a.m. during a startup.
Key Responsibilities
1. Operations Support & Troubleshooting
-
Serve as the process engineering point of contact for operating sites, supporting operators and technicians on day-to-day performance, upsets, and equipment issues.
-
Lead root-cause analysis on process deviations, off-spec product, and equipment underperformance; drive corrective actions to closure.
-
Monitor plant data and KPIs (methane recovery, product quality, energy intensity, availability) and translate trends into actionable engineering recommendations.
2. Process & Site Design
-
Develop and maintain PFDs, P&IDs, heat and material balances, equipment datasheets, line lists, and BOMs for new sites and modifications.
-
Build and review process simulations (HYSYS, Aspen, or equivalent) to size equipment and evaluate design, turndown, and off-design operating cases.
-
Specify and evaluate gas conditioning, separation, and conversion equipment — including PSA, TSA, membrane, cryogenic, and absorption/stripping systems, plus compression, refrigeration, heat exchange, and phase separation.
3. Commissioning & Startup
-
Support pre-commissioning, commissioning, and startup in the field, including system walkdowns, punch-list resolution, and operating procedure development.
-
Execute performance and acceptance testing with technology vendors; document results and close out guarantees.
-
Train operations personnel on process intent, normal operating windows, and abnormal-condition response.
