Requirements

At least 7 years of relevant engineering experience, supported by evidence of complex technical delivery, checking, and mentoring.
A relevant engineering degree, such as Mechanical, Civil, Electrical, Chemical, or Ocean Engineering, according to discipline, with demonstrated application.

Responsibilities

Develop discipline calculations, technical procedures, drawings, P&IDs, and engineering content for work packs, establishing assumptions, design basis, applicable codes, and acceptance criteria; use approved, validated calculation tools and understand their limitations.
Independently check others’ work within demonstrated competence, document review findings, confirm closure before authorized release, and maintain separation of preparation, checking, and approval.
Lead engineering for assigned ES and IIS scopes, which may include pipeline pre-commissioning, pigging, hydrotesting, dewatering, drying, nitrogen and leak testing, flange management, umbilicals, and inspection and integrity services.
Act as the principal technical contact for assigned scopes, coordinate technical discussions and clarifications with clients, Project Managers, and operations, resolve technical queries within delegated authority, and assess changes through management of change.
Specify equipment and engineering mobilization requirements and support pre-mobilization trials, function testing, and readiness reviews with maintenance, workshop, and logistics teams.
Provide technical leadership during site execution, working with the Project Manager and site supervisor to confirm compliance with approved procedures, resolve technical issues, and assess proposed changes within delegated authority.

Maintain controlled technical records, capture closeout lessons, and contribute reusable procedures, templates, and verified calculation methods to the global framework.
Plan and coordinate engineering activities, deliverables, resources, and interfaces to support agreed project milestones; report progress, dependencies, and delivery risks.
Develop and monitor engineering estimates and allocated budgets, identify variances, and recommend improvements that support project profitability without compromising safety or technical requirements.
Prepare and review technical requisitions, evaluate supplier technical submissions, and resolve technical clarifications with procurement and vendors.
Recommend engineering resources and competency requirements, allocate assigned engineering tasks, and identify specialist support needs.
Coordinate interfaces with other engineering disciplines and service lines to ensure an integrated and executable technical solution.
Provide verified technical progress records, completion evidence, and scope-change information to support project reporting, variations, and invoicing.
