Reporting to the System Design Manager, this role encompasses system design, engineering documentation, oversight, and systems engineering functions.

Key Responsibilities

1. Lead the design and development of gas and fluid systems from conceptual requirements through final design and commissioning.
2. Conduct technical trade studies and make informed decisions to refine system architecture.
3. Oversee supplier activities related to the development and fabrication of gas processing, filtration, and monitoring equipment.
4. Evaluate component designs within the context of complete system integration.
5. Prepare and review technical specifications, operational narratives, and system documentation.
6. Identify and resolve plant- and system-level integration challenges.
7. Support and participate in design reviews and ensure alignment with project requirements.
8. Develop and manage detailed design packages, including calculations, design reports, drawings, and specifications.
9. Interface with cross-functional teams to support P&IDs, 3D models, and interface drawings.
10. Coordinate with mechanical, I&C, civil, and nuclear engineering disciplines to define and meet system performance criteria.
11. Propose, initiate, and support system development testing and qualification programs.
12. Provide oversight and analysis during testing and compile comprehensive test reports.
