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
