Job Description

Company Overview

AESC is a general leader in lithium‑ion and LFP battery technology, with a fast‑growing footprint across Japan, the UK, France, China, and the USA—now expanding in Spain with a €1‑billion gigafactory in Extremadura that will create up to 900 direct jobs in phase one. The Spanish facility is designed as the first net‑zero industrial park gigafactory in the country, aligning with AESC’s mission to pioneer sustainable battery manufacturing.

Role Purpose

The Cost Engineer will own the cost control of the construction of AESC’s battery gigafactory in Navalmoral de la Mata, acting on behalf of AESC as owner/end-user. The role will prepare and maintain project estimates and budgets, define and review quantities for civil works and MEP packages, monitor actual cost against budget and forecast, and assess the economic impact of changes and risks. Working closely with the Commercial Manager, the Global Infrastructure & Construction (GIC) team, Chinese project/engineering teams, EPC contractors and consultants, the position will provide management with accurate and timely cost information to support decision-making.

Key Responsibilities

- Prepare cost estimates, budgets and cost analyses for civil works and MEP systems, and review preliminary and official budgets and reference prices.
- Define and review quantities, measurements and Bills of Quantities (BoQ) with engineering firms and consultants, to be used for tendering and cost control.
- Manage the full project cost control cycle: cost planning, monitoring,



variance analysis and forecasting (actual vs. budget, committed cost, forecast at completion).
- Prepare monthly cost reports and dashboards for management, highlighting deviations, trends and risks.
- Verify executed quantities and progress on site as the basis for certifications and payments to contractors and suppliers.
- Assess the cost and budget impact of scope changes, design modifications and claims, providing the technical-economic basis to the Commercial Manager.
- Identify economic risks early, quantify exposure and propose the required contingency.
- Analyse market prices for materials, equipment, labour rates and productivity, using local benchmarks.
- Support tender processes with cost input: bid comparison, price analysis and consistency between budget, contracts and procurement.
- Build and maintain the project cost database for benchmarking, and support the final cost close-out of the project.

Led by a diverse and experienced management team, AESC employs more than 14,000 professionals worldwide.
