Project Engineer

HERACLES Group, Greece's leading company in innovative and sustainable building solutions and a member of HOLCIM, is seeking to recruit a Project Engineer. With sustainability at the core of our strategy, the "OLYMPUS" is a pioneering project aiming to fulfill our zero-carbon commitment. Our goal is the green transformation of our Group's cement production plant in Milaki, Evia, into a net zero carbon facility, utilizing innovative carbon capture technologies. 

Based in our Athens Head Offices, you will join our Project Team for this large-scale CO2 emissions avoidance "OLYMPUS" Carbon Capture project that will spearhead the decarbonization of energy intensive industries. OLYMPUS is a flagship project in Holcim’s European decarbonization roadmap. It will lead to the development of storage capacity in southern Europe. With a target operational date of 2028, the project aims to capture and store 1 million tons of CO₂ annually. In 2023, the project was selected for a grant from the EU Innovation Fund.

The Role

The Project Engineer will be responsible for the engineering coordination, execution, and overall technical integrity of assigned project areas within the OLYMPUS project. The role covers a wide spectrum of related facilities (cement line retrofitting, WHR, alternative fuels, carbon capture plant, jetty, utilities, etc.) and requires close collaboration with Engineering Providers, Vendors, Subcontractors, and the Project Management Team. You will ensure that engineering, procurement, and construction activities meet project specifications, budget, quality standards, environmental and permitting requirements, as well as strict Health & Safety criteria.
●    Manage and coordinate all engineering activities related to the assigned process areas, ensuring alignment with project specifications, environmental and permitting requirements.
●    Review and approve engineering deliverables from Subcontractors and Vendors, ensuring technical compliance, quality, completeness, and timely issuance.
●    Oversee interface management and battery limit definitions between different engineering entities, vendors, and subcontractors.
●    Lead and participate in technical reviews, including HSED, constructability, layout, and basic/detailed design reviews.
●    Ensure cost-effective and technically robust design solutions; identify risks and define mitigation actions.
●    Manage technical queries, design changes, modifications, and promptly resolve engineering issues.
●    Organize and maintain technical documentation, ensuring proper distribution to stakeholders.
●    Prepare technical specifications for engineering services, procurement packages, and construction contracts.
●    Lead technical clarifications during tendering, participate in vendor/subcontractor evaluation, bid analysis, negotiations, and selection.
●    Follow vendor manufacturing progress, coordinate inspections, ensure equipment compliance with regulations, and monitor delivery schedules through clear dashboards.
●    Provide technical support to the construction phase, including handling modifications, resolving non-conformities, and ensuring that construction teams receive all necessary technical documentation.
●    Participate in preparing construction and commissioning schedules and acceptance procedures for process facilities.
●    Coordinate technical teams (including Vendors and Engineering Providers) to support jobsite needs, ensuring work fronts are available and delays/claims are minimized.
●    Monitor progress and schedule deviations, assess cost impacts, and prepare relevant documentation to support project controls and negotiations.
●    Apply collaborative working methodologies and engineering digital tools; participate in gathering final documentation.

Key Success Factors & Prerequisites:

●    Ability to manage and coordinate complex technical scopes and multidisciplinary interfaces.
●    Strong problem-solving and decision-making skills with a proactive, structured approach.
●    Clear and transparent reporting, progress monitoring, and risk visibility.
●    Effective collaboration with engineering partners, contractors, and internal stakeholders.
●    Strong commitment to H&S and environmental compliance.
●    Availability for site visits and meetings with Designers, Vendors, and Subcontractors.

What are we looking for

●    Bachelor’s degree in Engineering ; Master’s degree is an asset.
●    Proven experience in project execution within heavy industries (cement, power, gas treatment, oil & gas, or manufacturing).
●    Experience in managing large-scale projects with budgets above €50M.
●    Strong technical background enabling effective review of multidisciplinary engineering deliverables.
●    Proficiency with engineering tools (AutoCAD, Navisworks or similar).
●    Strong organizational, communication, and interpersonal skills.
●    Ability to perform effectively in demanding, fast-paced industrial project environments.
●    Solid understanding of safety protocols and regulatory frameworks.

What we offer you

●    Opportunity to contribute to a pioneering CCS project with major environmental impact.
●    A collaborative work environment in a leading industrial organization.
●    Competitive compensation and benefits package.
●    Professional growth and long-term development opportunities.
