Vacancy Details & Baseline Criteria

Estimating Engineer

• Department: Capital Program Management Division
• Employment Type: Full-Time (Exact schedule to be specified in the formal job offer)
• Job Location: Within the Kingdom of Saudi Arabia (Dhahran / Specific location to be confirmed in the formal offer)
• Target Audience: Expatriate / US Candidates (and eligible global applicants)

• Degree: Bachelor's degree in an Engineering discipline from an approved and recognized university. Preference will be given to degrees in Mechanical Engineering, Civil Engineering, Chemical Engineering, or Electrical Engineering.

Required Experience & Technical Skills

• Industry Experience: A minimum of ten (10) years of direct experience in capital project cost estimating, budgeting, and project controls within the oil and gas, petrochemical, or heavy industrial construction sectors.
• Cost Estimation Methodologies: Deep understanding of Association for the Advancement of Cost Engineering (AACE International) standards for Class 1 through Class 5 project cost estimates.
• Estimation Software Mastery: Proven proficiency using industry-standard estimation and simulation platforms such as Aspen Capital Cost Estimator (ACCE), Timberline, Timberline Precision, or equivalent enterprise software.
• Project Scheduling Frameworks: Practical familiarity with project scheduling tools like Primavera P6 to analyze how project duration, escalation, and resource constraints affect total capital expenditure (CAPEX).
• Data Science & Analytics Tools: Advanced skills in data manipulation, cost indexing, and forecasting using Excel, Power BI, SAP, or equivalent enterprise resource planning systems.
• Commercial & Market Acumen: Proven ability to analyze global commodity pricing, labor market productivity rates, fabrication yard capacities, and supply chain logistics to calculate accurate regional escalation factors.
• Preferred Certifications: Holding professional credentials such as Certified Cost Professional (CCP), Certified Estimating Professional (CEP), or Project Management Professional (PMP) is highly advantageous.

Key Responsibilities & Job Duties

• Develop, review, and validate comprehensive capital cost estimates for mega-projects during all phases of development, from initial scoping and conceptual design to final investment decision (FID).
• Utilize deterministic and probabilistic estimating techniques to generate highly accurate equipment, material, labor, and construction cost breakdowns.
• Collaborate closely with project management teams, front-end engineering design (FEED) contractors, and procurement departments to capture all aspects of project scope.
• Conduct detailed risk assessments and Monte Carlo simulations to establish appropriate project contingency levels and risk-exposure profiles.
• Analyze contractor commercial bids and structural estimates, identifying variances, cost-drivers, and potential optimization areas.
• Establish and update standard cost-estimating databases, historical data files, and benchmarking metrics to improve future estimating accuracy.
• Present finalized cost estimates, risk analyses, and financial business cases directly to senior corporate executive committees for project approval.
• Track global supply chain trends, currency fluctuations, and localized labor productivity to adjust escalation models dynamically.

Expert Advice for Applicants

• Differentiate by Project Scale: Saudi Aramco deals primarily with mega-projects and giga-projects. When drafting your CV or portfolio, do not just say you estimated projects; explicitly state the monetary size and type of assets you managed (e.g., "Led Class 2 cost estimation for a $1.5 Billion downstream refinery expansion").
• Align with AACE Terminology: The screening team relies heavily on structural definitions from AACE International. Ensure your experience descriptions clearly reference specific estimate classes (Class 5 to Class 1) and stage-gate frameworks to prove your formal methodological training.

Highlight Contingency Modeling Skills: Precision is critical. If you have practical experience running quantitative risk analyses (QRA) or setting up statistical contingency modeling using specialized simulation tools, feature this heavily on the first page of your profile to distinguish yourself from baseline estimators.
