Senior Project Engineer – Oxy-Combustion

• Own the island process design basis: heat and material balances, operating envelopes, and air-fired, oxy-fired and transition cases across load and ambient conditions

• Review and approve PFDs, P&IDs, datasheets, line lists and control narratives from the design engineer and OEMs; lead 30/60/90 design and model reviews

• Define and manage process interfaces with the ASU, CPU, steam turbine-generators and air-cooled condenser (O₂ purity and pressure, flue gas composition to CPU inlet spec, air in-leakage limits, steam conditions)

• Lead HAZOP, LOPA and SIL reviews with focus on oxygen service, oxygen-enriched and high-CO₂ atmospheres; drive action close-out

• Collaborate with Supply Chain on: technical specifications, RFPs and material requisitions for island packages

• Prepare technical bid evaluations and recommend awards

• Manage OEM technical deliverables, vendor document review and design changes; protect performance guarantees

• Witness shop inspections and factory acceptance tests for critical equipment

• Serve as owner's technical lead on site for the island; resolve RFIs, field changes and nonconformances

• Develop and own the island commissioning strategy with the commissioning lead: system turnover, first fire on air and staged transition to oxy firing

• Lead troubleshooting and tuning of flue gas recirculation, oxidant flow and O₂ trim control with the OEM and controls team

• Plan and witness performance and guarantee testing; close punch items through COD; deliver turnover packages and operations readiness

• Maintain the island technical risk register, interface register and change log; flag engineering-driven schedule risk early

• Support cost and schedule updates for stage gates; manage technical change orders

• Develop engineering procedures, design guides and lessons learned so the island becomes more repeatable at each Energy Park campus

• Bachelor's in Chemical or Mechanical Engineering (Chemical preferred); PE a plus

• 10+ years of engineering experience on power or industrial process projects, including 5+ as a project or lead engineer

• Delivered at least one major combustion, steam generation, gas processing or similar process unit from detailed design through commissioning and startup

• Hands-on field experience during construction, commissioning and startup troubleshooting

• Oxy-combustion, oxy-fuel or carbon capture experience is a strong plus

• Process engineering: heat and material balances, PFDs and P&IDs, process simulation (Aspen Plus/HYSYS, Thermoflex or equivalent)

• Boilers/HRSGs, burners, flue gas recirculation, burner management systems and combustion controls

• Process safety: HAZOP, LOPA, SIL; oxygen service design and cleaning (CGA G-4.4 / EIGA practices)

• Flue gas treatment (SCR, direct contact coolers) and CO₂ compression, purification or cryogenic air separation interfaces

• Performance testing to ASME PTC standards; performance guarantees and OEM warranties

• Technical bid evaluation, vendor document control and scheduling tools (Primavera P6 or MS Project)

• Experience working with internal and external stakeholders (internal SMEs, OEMs, owner's engineer, contractors, GC)

• Owns outcomes end to end; holds vendors and designers to specification and guarantee

• Ability to unblock blockers, anticipate and resolve issues in a dynamic, early-stage environment

• Strong safety leadership around oxygen handling and high-CO₂ atmospheres

• Willing to travel ~50% to vendor shops and the West Texas site, and to take an extended onsite assignment during construction and commissioning

• Willingness to learn new technologies, evaluate and explore new ideas
