About the company:

KIEFER is building Greece's integrated AI ecosystem. From renewable energy infrastructure and AI systems to robotics and enterprise applications, we connect the technologies that power Europe's intelligent future. Founded in 2014, KIEFER has delivered 600MW+ of energy projects and is now developing sovereign AI infrastructure, enterprise AI products and physical AI systems for Greece and Southeast Europe.

KIEFER TEK Ltd is a leading EPC contractor in the renewable energy sector, delivering complex energy infrastructure projects across Greece.

As our Battery Energy Storage Systems (BESS) portfolio continues to grow, we are strengthening our project delivery team and looking for an experienced Project Manager to take end-to-end ownership of utility-scale BESS projects — from contract award and project planning through engineering, procurement, construction, commissioning and final handover.

This is a head-office–based role with selective site presence, designed for a Project Manager who can maintain the full project picture: contract, scope, schedule, cost, risk, client and overall delivery.

What You Will Own

Take end-to-end accountability for BESS projects, from project kick-off through commissioning and final handover

Define and drive the project execution strategy, programme, budget, milestones and key deliverables

Ensure compliance with EPC contractual obligations, technical requirements and agreed project milestones

Own project financial performance, monitoring budget, forecast, cash flow, cost-to-complete and commercial exposure

Act as the primary project interface with the client, maintaining clear communication, alignment and timely decision-making throughout the project lifecycle

Coordinate Engineering, Procurement, Construction, HSE, Finance, subcontractors, consultants and suppliers around a single integrated delivery plan

Ensure engineering, procurement and construction activities remain aligned with project priorities and contractual milestones

Provide direction and coordination to Construction and Site Management teams, while retaining overall accountability for project performance and delivery

Identify project risks and critical issues early, establish mitigation actions and drive them through to resolution

Manage project changes, variations and claims in coordination with Commercial, Engineering and Construction teams

Lead project progress meetings, reviews and reporting with clients, internal stakeholders and senior management

Maintain effective oversight of construction progress through targeted and purposeful site visits, without being responsible for day-to-day site supervision

Drive projects toward safe, timely and commercially successful completion

Who We’re Looking For

Engineering degree, preferably in Electrical, Mechanical, Civil Engineering or another relevant discipline

Proven experience in Project Management within EPC, energy, renewable energy or major infrastructure projects

Strong understanding of the interaction between engineering, procurement, construction, contracts, cost and schedule

Experience managing complex projects with multiple internal and external interfaces

Strong commercial awareness and confidence working with budgets, forecasts, variations, contractual requirements and project risks

Confident client-facing communication, stakeholder management and negotiation skills

Structured, accountable and proactive approach, with the ability to maintain control of multiple priorities

Previous experience in BESS, renewable energy, substations or complex electrical infrastructure will be considered a strong advantage

Ability to understand site realities while maintaining focus on overall project performance rather than day-to-day construction supervision

Interest in long-term involvement and professional growth within a rapidly expanding energy-storage portfolio
