The Senior Project Engineer owns the technical delivery of Heirloom's oxy-combustion island cradle to grave, from detailed design through procurement, construction, commissioning, performance testing and COD. A process engineer at heart, the role owns the island's heat and material balances, and the interfaces where steam generation, oxygen supply, flue gas treatment and CO₂ processing meet, then drives designers, OEMs and contractors to deliver on performance, schedule and safety. Provides technical oversight of: process design basis and heat and material balances, PFDs and P&IDs, equipment specifications and datasheets, control narratives, HAZOP/LOPA/SIL, technical bid evaluations, vendor document review, inspection and test plans, FAT, commissioning, and performance and guarantee testing. Process Design & Integration 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 Procurement & Vendor Management 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 Construction, Commissioning & Turnover 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 Project Controls 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 Education/Qualifications/Experience 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 Knowledge/Skills (including Technology) 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) Attributes/behaviours 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 Our Commitment to Diversity, Equity, and Inclusion We encourage you to apply if you identify as Black, Native Hawaiian or Pacific Islander, American Indian or Alaskan Native, Hispanic or Latino, LGBTQ+ – or with any other underrepresented group – even if you don’t tick all the boxes in the description below.
