Senior Process Engineer – Biofuels Operations

About this role

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.

4. Continuous Improvement & Optimization

• Identify, justify, and execute debottlenecking and reliability projects that improve throughput, methane recovery, energy use, and operating cost.

• Own management-of-change for process modifications, from concept and economic justification through field implementation and as-built documentation.

• Capture lessons learned across sites and feed them back into standard designs and operating practices.

5. Process Safety & Compliance

• Lead or actively participate in HAZOP/PHA, LOPA, and relief-system reviews; track and close resulting action items.

• Ensure designs and modifications comply with applicable codes and standards (e.g., ASME, API, NFPA) and site permit conditions.

• Partner with HSE and regulatory teams on emissions, monitoring, and reporting requirements for renewable fuels assets.

6. Vendor & Cross-Functional Collaboration

• Work with technology vendors, consulting engineers, and EPC partners on equipment selection, design reviews, and field support.

• Coordinate closely with project management, construction, controls, and operations to keep design intent intact through execution.

• Stay current on emerging bio-methanol, RNG, and gas-conversion technologies and bring relevant options to the team.

Required Qualifications

• B.S. in Chemical Engineering (or closely related discipline) and 10+ years of process engineering experience in gas processing, chemicals, refining, or renewable fuels.

• Hands-on design and operating experience with gas separation and treating unit operations — PSA, TSA, membrane, cryogenic, and/or chemical absorption and stripping — plus supporting equipment such as compression, refrigeration, heat exchange, and phase separation.

• Demonstrated ownership of PFDs, P&IDs, heat and material balances, and BOMs, and active participation in HAZOP or other process hazard analyses.

• Proficiency with process simulation software (HYSYS, Aspen, Pro/II, or equivalent) applied to real design, performance, and troubleshooting problems.

• Field-proven commissioning, startup, and troubleshooting experience, with the communication skills to work shoulder-to-shoulder with operators, contractors, and vendors, and willingness to travel to project and operating sites as needed.

Preferred Qualifications

• Direct experience with RNG, landfill gas, biogas upgrading, or methanol/bio-methanol production — highly desired, though not required.

• Experience commissioning and starting up new facilities, including vendor-witnessed performance testing.

• Familiarity with reciprocating engines and generator sets, reactors, thermal oxidizers or flares, and rotating equipment in remote or lightly attended service.

• Experience in a start-up or small-team environment where engineers own problems end to end; EIT or PE licensure a plus.
