Project Engineers - Carbon Capture Plant & Water Treatment Systems

HERACLES Group, Greece's leading company in innovative and sustainable building solutions and a member of HOLCIM, is seeking to recruit two Project Engineers to join the OLYMPUS Carbon Capture project core team.

With sustainability at the core of our strategy, OLYMPUS is a pioneering project aiming to fulfill our zero-carbon commitment. The project will transform our cement production plant in Milaki, Evia, into a net zero carbon facility through the implementation of innovative carbon capture technologies and supporting infrastructure.

Based in our Athens Head Offices, you will join a large-scale industrial project that will spearhead the decarbonization of energy intensive industries in Europe. OLYMPUS is a flagship project in Holcim’s European decarbonization roadmap and was selected in 2023 for funding by the EU Innovation Fund. With a target operational date of 2030, the project aims to capture and store 1 million tons of CO₂ annually.

We are currently looking for two engineering professionals who will support the technical coordination and engineering execution of the following project areas:

●    Project Engineer – Carbon Capture Plant
Responsible for the engineering coordination and execution of the Carbon Capture Plant, including detailed design follow-up, technical coordination, and site support activities. The role requires previous experience in cryogenic plants, gas producing facilities, refineries, or similar industrial process installations. 

●    Project Engineer – Water Treatment & Desalination Plant
Responsible for the engineering coordination and execution of water treatment plants, including industrial wastewater and desalination facilities, ensuring proper integration with the overall industrial infrastructure and project requirements. The role requires previous experience in similar industrial process installations.

The Role
The Project Engineers will be responsible for the coordination, execution, and technical follow-up of their assigned project scope throughout all project phases, from engineering and procurement to construction and commissioning.
Working closely with Engineering Providers, Vendors, Subcontractors, and the Project Management Team, the successful candidates will ensure that engineering, procurement, and construction activities are delivered according to project specifications, budget, schedule, quality standards, environmental requirements, and strict Health & Safety criteria.

Key Responsibilities
●    Manage and coordinate all engineering activities related to the assigned project area. 
●    Support permitting and environmental activities by coordinating technical inputs and engineering deliverables. 
●    Review and approve engineering deliverables issued by Engineering Providers, Vendors, and Subcontractors, ensuring technical compliance, quality, completeness, and timely issuance. 
●    Lead and participate in technical reviews, including HSED reviews, constructability reviews, layout reviews, and design maturity assessments. 
●    Ensure technically robust and cost-effective engineering solutions while proactively identifying project risks and mitigation actions. 
●    Manage interfaces and technical coordination between subcontractors, vendors, utilities, and existing plant systems. 
●    Organize and maintain technical documentation and ensure proper document control throughout the project lifecycle. 
●    Prepare technical specifications and technical sections for engineering services, procurement packages, and construction contracts. 
●    Lead technical clarifications during tendering processes and participate in vendor/subcontractor evaluation, technical bid analysis, negotiations, and selection. 
●    Coordinate technical follow-up of vendors and suppliers, ensuring compliance with project requirements, applicable regulations, and safety standards. 
●    Provide technical support during construction and commissioning phases, including handling modifications, resolving non-conformities, and ensuring timely delivery of engineering documentation to site teams. 
●    Participate in the preparation of construction schedules, commissioning activities, acceptance procedures, and project implementation planning. 
●    Monitor engineering progress, identify schedule deviations and potential cost impacts, and support project controls and reporting activities. 
●    Apply collaborative working methodologies and engineering digital tools while ensuring proper collection and organization of final project documentation. 
●    Support maintenance readiness activities by ensuring proper documentation, inspection routines, and maintenance requirements for new equipment.

Key Success Factors & Prerequisites:
●    Ability to manage and coordinate complex technical scopes and multidisciplinary engineering interfaces.
●    Strong problem-solving and decision-making skills with a proactive and structured approach.
●    Effective coordination and communication with engineering partners, contractors, suppliers, and internal stakeholders.
●    Strong organizational and planning capabilities with clear reporting and progress monitoring skills.
●    Ability to work effectively in demanding, fast-paced industrial project environments.
●    Strong commitment to Health, Safety, and Environmental compliance.
●    Availability for meetings and visits to Designers, Vendors, Subcontractors, and project sites.

What are we looking for

●    Bachelor’s degree in Engineering; Master’s degree is considered an asset.
●    Proven experience in engineering management and project execution in heavy industries.
●    Experience in large-scale industrial projects relevant to the role.
●    Strong multidisciplinary technical background enabling effective review and coordination of engineering deliverables.
●    Good understanding of industrial utilities, equipment integration, and construction interfaces.
●    Experience in managing Engineering Providers, Vendors, and Subcontractors in complex industrial environments.
●    Knowledge of relevant industrial standards, engineering practices, and regulatory requirements.
●    Proficiency with engineering and coordination tools (AutoCAD, Navisworks, or similar).
●    Strong leadership, communication, and interpersonal skills.
●    Ability to perform effectively in demanding, fast-paced project environments.
●    Solid understanding of industrial safety standards and procedures.

What we offer you

●    Participation in one of Europe’s most ambitious industrial decarbonization projects.
●    A collaborative work environment in a leading industrial organization.
●    Competitive compensation and benefits package.
●    Professional growth and long-term development opportunities.

All applications will be treated with strict confidentiality.
