DATA4'S MISSION

DATA4 creates Smart & Scalable digital facilities for our customers. Our network of highly connected, resilient and sustainable data center campuses underpins our customers’ digital growth in Europe.

DATA4 Group finances, designs, constructs and operates its own data centers. Delivered through our data center campus model, we provide our customers with secure, scalable and high-performance data hosting solutions.

DATA4 VALUES

At DATA4, we are driven by our values. These are the core of everything we do – from the proactivity we show in delivering great outcomes for our clients, to the responsibility we show as a key contributor to the digital economy. Our three values are:

1. To be entrepreneurial – we are teams of doers who make things happen - with autonomy, energy and a sense of responsibility
2. To always take responsibility – for our impact on the people we work with, the society we are part of, and the environment in which we operate
3. To constantly be adaptable – our business is designed to adapt, answering not only today’s challenges, but also anticipating what’s coming next.

ABOUT THE ROLE

Delivering a data centre on time is about far more than a date on a program. Power availability, long-lead equipment, commissioning sequences and customer handover all have to come together at exactly the right moment. As our Senior Planning & Risk Engineer, you will be the person who sees that picture clearly and helps everyone else see it too.

You will own the integrated schedule and the schedule-risk view for a major campus development, starting at Marcoussis. That means building and assuring the master program, holding contractors to credible plans, managing the critical path, running quantitative risk analysis and giving leadership forecasts they can trust and act on. It is a hands‑on leadership role with real influence over how our projects are delivered.

RESPONSIBILITIES

Build and own the integrated schedule

• Develop, maintain and assure integrated Level 1-4 schedules covering design, permitting, procurement, construction, energization, commissioning, handover and Ready for Service (RFS).
• Bring multiple project and contractor programs together into one coherent campus master schedule, with clear interfaces, milestones, logic and ownership.
• Make sure every schedule is fully logic‑linked, resource‑aware where it matters, aligned with contractual obligations and backed by credible progress evidence.
• Set up and maintain baselines, coding structures, calendars, WBS, schedule narratives and change‑control records in Primavera P6 EPPM.

Protect the critical path and forecast with confidence

• Analyze critical and near‑critical paths, float, constraints and schedule drivers, and keep a clear distinction between contractual, deterministic and risk‑adjusted dates.
• Constructively challenge contractor updates, progress measurement, productivity assumptions and sequencing, using evidence rather than opinion.
• Prepare scenario analyses, time‑impact assessments and recovery plans with clear actions, owners and decision dates.
• Keep a close eye on long‑lead equipment, grid power availability, utility interfaces, testing and commissioning dependencies that could affect energization or RFS milestones.

Lead schedule risk management

• Lead risk identification, qualitative assessment and quantitative schedule risk analysis, including risk workshops and Monte Carlo simulation.
• Keep the integrated schedule, risk register, assumptions, opportunities and mitigation actions aligned with one another.
• Use Primavera Risk Analysis, Safran Risk or equivalent tools to produce P50, P70 and P90 forecasts, sensitivity analysis and the key drivers behind them.
• Turn risk outputs into practical mitigation priorities and clear, decision‑ready recommendations for project and senior leadership.

Communicate, influence and raise the bar

• Produce concise weekly and monthly schedule reports, milestone dashboards, look‑aheads, variance analysis and management narratives.
• Explain complex schedule and risk information in plain terms to project directors, design, procurement, construction, commissioning and operations teams, contractors and external stakeholders.
• Chair planning reviews and risk workshops, follow actions through to close‑out and raise material threats early with fact‑based recommendations.
• Champion consistent planning standards, mentor planners and help improve our project controls processes and data quality.

REQUIREMENTS

Experience

• At least 15 years of progressive experience in construction planning, project controls or schedule risk management on major capital projects.
• A bac
