Piping Valve Vessel Engineer

Position: Piping Valve Vessel Engineer
Location: Afungi, Mozambique
Rotation: 28/28
Duration: 12 months renewable
Start date: October 2026

The Site Piping & Valve Engineer acts as the bridge between home-office engineering and on-site construction execution. The role ensures the technical integrity of all piping and valve systems from construction through to pre-commissioning and mechanical completion, working in close collaboration with EPC Contractors, QA/QC teams, and commissioning stakeholders.
 
Key Responsibilities

Technical Support — Engineering to Construction Interface

• Provide day-to-day discipline technical support for all piping and valve matters on site.
• Ensure correct interpretation and application of engineering deliverables: isometrics, valve datasheets, material specifications, piping layouts, and 3D model extracts.
• Process and respond to Contractor Technical Queries (TQ), Deviation Requests (DER),

Concession Requests, and site clarifications in a timely manner.

• Coordinate with home-office engineering to resolve design discrepancies or information gaps impacting site execution.

 
Construction Support

• Assist construction teams with technical clarifications for piping and valve installation, welding, testing, flushing, and reinstatement.
• Review construction documentation: ITPs, WPS/PQRs, erection plans, and test packs.
• Participate in joint inspections for piping and valves including weld/NDE checks and material conformity verification.
• Monitor proper handling, preservation, and installation of all valve types (manual, actuated, control, and cryogenic).

 
Pre-Commissioning & Commissioning Assistance

• Support preparation and review of pre-commissioning and commissioning procedures: hydrotest, pneumatic tests, cleaning, drying, and leak testing.
• Verify test pack completeness, punch list closure, and discipline walkdowns.
• Follow progress of as-built mark-ups, mechanical completion dossiers, and ICAPS inputs.

 
Interface & Coordination

• Interface with Civil, Mechanical, Electrical, Instrumentation, QA/QC, and Commissioning teams on piping and valve topics.
• Participate in interdisciplinary meetings to report discipline issues, flag constructability concerns, and support practical solutions.
• Liaise with Contractor engineering teams and vendors to clarify technical points and follow up on pending actions.

 
HSE & Quality

• Apply and promote Project HSE requirements across all piping and valve activities.
• Support quality control activities: welding inspections, NDE follow-up, valve testing, and discipline documentation verification.

 
Required Profile

Education

• Engineering degree in Mechanical, Piping, Petroleum, or equivalent field.

Experience

• 10+ years of experience in piping and valve engineering on major oil & gas projects, including LNG.
• Strong background in piping design, layout, materials, valves, stress and vibration analysis, fabrication, welding, testing, FAT, and construction methods.
• Experience with cryogenic valves and large-bore valve systems.
• Proficiency with engineering deliverables: P&IDs, isometrics, 3D models, and site construction workflows.

 
Languages

• English: fluent written and spoken — mandatory.
• Portuguese or French: beneficial for local interface.
