Senior Process Engineer – Biofuels Operations

Job description

**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. **Compensation & Benefits** M2X Energy offers excellent benefits and career opportunities. We believe our company's strength is a product of our employees, which are the most important element of our company. Our company embraces a highly collaborative, supportive, and ambitious work culture. - Health, dental, and vision insurance - 401(k) - Paid time off and holidays - Professional development assistance **Job Type:** Full-time **Work Location:** Rockledge, FL, Hybrid or Fully Remote **Travel:** Approximately 40% **Work Authorization:** Must be eligible to work in the United States. **Equal Opportunity Employer:** At M2X Energy, we are working toward a low-carbon, sustainable future for everyone in the world. We are committed to creating an inclusive environment for all our employees and are seeking to build a team that reflects the diversity of the people we hope to serve with our global, revolutionary products. M2X Energy is proud to be an equal opportunity employer. **About the Company** M2X Energy is converting wasted methane into low-carbon methanol using modular systems to create immediate environmental and economic value.
