The Mechanical Engineer for the New Unit Business (NUB) is in conjunction with the Project Manager and the Procurement Buyers. Ensures the major sub-order equipment meets the technical requirements outlined in the Customer and MCO technical standard. Expedite the required deliverables from internal/external stakeholders and facilitate timely deliveries of the orders. Responsible for documentation in the execution stage for Lube Oil System and other major sub-order equipment, such as Surface condenser, Gearbox, etc. Also, to have technical support on technical trouble at the vendor/MCOI factory or at the site for the Lube Oil System.

The Auxiliary Engineer serves as an MCO-I in-house extension of the MCO engineering team, supporting execution of auxiliary systems (e.g., lube oil consoles and packaged equipment) at the vendor and at Pearland Works as needed.

The role initially focuses on strengthening and expediting the effectiveness of Lube Oil Consoles through technical support, including validation of vendor progress, resolution of engineering issues, and improved schedule visibility. Over time, the role evolves to provide MCO-I in-house engineering decision-making authority and support the expansion of auxiliary scope and capabilities at MCO-I.

This position bridges engineering, project management, procurement, and vendor execution to ensure timely delivery, technical compliance, and scalable in-house capability development.

Roles and Responsibilities

1) Technical Support to Expediting (Initial Focus)

• Support expediting activities by validating vendor-reported progress against engineering scope and milestone completion
• Confirm that reported progress aligns with actual engineering completion and readiness
• Identify and resolve technical blockers impacting schedule execution
• Provide real-time engineering clarification to vendors during fabrication and assembly
• Support development and tracking of milestone-based progress (in lieu of % complete where required)

2) Vendor Execution Oversight

• Participate in vendor meetings and site visits to provide engineering decision support
• Verify that fabrication, assembly, and testing align with design intent and specifications
• Challenge and validate vendor progress using technical criteria and engineering standards
• Support identification of critical path activities and technical risks

3. Engineering Issue Resolution

• Act as the primary MCO-I interface between the vendor and MCO Engineering
• Expedite resolution of:

1. 1. 1. Design clarifications
      2. Material substitutions
      3. Instrumentation and piping questions
      4. Test procedures and deviations

• Reduce engineering response cycle time to support schedule adherence

4. Milestone & Readiness Validation

• Define and validate engineering-based milestone gates (e.g., assembly complete, FAT readiness, Ready-to-Ship)
• Ensure milestones are technically achieved before being reported complete
• Support accurate and objective progress visibility for project teams

5. Transition to MCO-I Engineering Authority (Planned Evolution)

• Progressively assume defined engineering decision-making authority within approved limits
• Support local approval of:

1. 1. 1. minor design adjustments
      2. vendor clarifications
      3. non-critical deviations

• Reduce dependency on MCO for routine engineering decisions

6. Localization & Scope Expansion

• Identify opportunities to increase local execution of auxiliary systems
• Support development of local fabrication, assembly, and integration capabilities (GSMs, Local Gauge Boards, etc.)
• Collaborate with Procurement and Operations to:
  • • qualify local vendors
    • expand local work scope
    • improve cost and lead time competitiveness

• Support standardization of auxiliary designs for local execution

7. Cross-Functional Collaboration

• Work closely with:

1. 1. 1. Project Management (schedule and execution alignment)
      2. Procurement (vendor performance and escalation support)
      3. HQ Engineering (design authority and technical alignment)

• Provide technical input to support commercial and execution decisions

8. Risk Identification & Mitigation

• Identify risks related to:

1. 1. incomplete engineering
   2. vendor misinterpretation
   3. design ambiguity
   4. rework potential

• Proactively recommend actions to prevent schedule delays and execution issues

9. Role Boundaries (Critical Clarification for long-term view of role)

• This role does not perform routine expediting administration, including:

1. 1. daily status chasing
   2. report ownership
   3. schedule tracking ownership

• The role enhances expediting through technical expertise and engineering authority, not administrative coordination.
• Other duties, responsibilities, and activities may change or be assigned at any time with or without notice.
