As Environmental Manager for the Grand Paris Express infrastructure management directorate (GIGP), you will oversee operational environmental compliance and performance across major transit assets. You will translate broad environmental policies into ground-level action across maintenance depots, rail networks, and operational teams, steering regulatory oversight, incident preparedness, and continuous monitoring.
This role places you at the heart of Europe’s largest urban mobility buildout, directly driving decarbonisation, resource preservation, and climate resilience for critical public transport infrastructure. By embedding circular economy practices, curbing pollution, and managing biodiversity risks within day-to-day railway maintenance, you will help secure a durable footprint for the capital’s automated metro lines.
This suits someone who blends deep regulatory expertise in industrial operations with the field diplomacy required to anchor sustainable practices across technical and engineering teams.
Job FAQs
What are the main missions and responsibilities of this role?
The primary mission is to operationalize RATP Infrastructures' environmental policy across the Grand Paris infrastructure unit. You will lead regulatory compliance across critical assets, ensuring strict adherence to environmental legislation such as ICPE frameworks, waste streams, water management, and contaminated soils. Additionally, you will steer environmental management systems (ISO 14001), track performance metrics, and carry out regular field audits and inspections.
On an ongoing strategic level, you will guide investment, maintenance, and operations projects toward lower environmental impacts across their whole lifecycle. This includes deploying concrete roadmaps for asset decarbonization, climate change adaptation, circular economy loops, and biodiversity protection. You will also manage response protocols for unexpected environmental incidents and lead internal feedback loops to prevent recurring operational risks.
Key learning opportunities for this job
Working within the Grand Paris Express ecosystem provides an unparalleled vantage point on large-scale sustainable transit engineering. You will gain in-depth expertise in integrating ISO 14001 and ISO 50001 standards into newly commissioned, high-tech rail infrastructures from the handover phase through long-term maintenance.
The role also offers opportunities to build specialized knowledge in industrial climate adaptation methodologies, life-cycle assessments of railway assets, and complex French environmental regulatory procedures (such as ICPE and water laws). Operating within a matrixed multi-thousand-person business unit will significantly sharpen your ability to negotiate change management across public authorities, engineering contractors, and technical operations.
How does the ideal candidate look like (experience, skills)?
The ideal candidate brings around five or more years of professional experience in operational environmental management, preferably acquired within industrial facilities, transport networks, or complex infrastructure projects. A Master's degree (Bac+5) in environmental engineering, energy, or civil engineering provides the expected technical backbone.
Key competencies include a sharp mastery of French environmental regulations (ICPE, waste, soil, water) and proficiency in standard management frameworks like ISO 14001. Beyond technical and analytical acumen, strong interpersonal communication, field credibility, and change-management skills are vital to engage operational staff who may prioritize daily operational output over environmental constraints.
Advice to stand out and make a successful application
To stand out, highlight specific operational achievements rather than generic environmental strategy concepts. Detail instances where you successfully managed regulatory inspections, audited industrial or technical sites, or resolved non-conformities under strict operational deadlines.
Demonstrating familiarity with the specific technical realities of rail or public transport maintenance will give you a decisive edge. In your cover letter or interview prep, articulate how you bridge administrative and compliance requirements with on-the-ground support for maintenance teams, showing that you act as an enabler for operational resilience rather than just an auditor.
What aspects of the company's sustainability is this role likely to focus on?
This position concentrates on the operational and ecological footprint of transport infrastructure. Key priorities include tracking and reducing resource consumption, managing chemical and hazardous substances, ensuring proper industrial wastewater handling, and protecting local ecosystems and biodiversity adjacent to transit corridors.
Furthermore, the role addresses climate adaptation and asset decarbonization, planning resilience measures against heat waves, flooding, or severe weather that could disrupt network continuity. Circular economy initiatives, particularly the reuse and recycling of construction and maintenance materials, will also form a core pillar of your mandate.
What are the main challenges someone in this role might face?
A primary challenge will be navigating the transition from infrastructure delivery to live maintenance operations on the newly constructed Grand Paris Express lines. You will need to establish operational environmental routines from scratch across unfamiliar facilities while keeping pace with strict project handovers.
Another significant hurdle is instilling an environmental culture among technical, maintenance, and engineering teams that operate under intense pressure for network reliability and service continuity. Balancing formal compliance obligations with pragmatic, fast-paced field requirements will demand high emotional intelligence, diplomacy, and persistence.
How could a typical day look like for someone in this position?
A typical day could start with reviewing site monitoring data and environmental metrics, such as energy usage or waste tracking, from maintenance centers. Mid-morning might involve conducting an on-site audit or environmental inspection at a rail depot or station technical room, evaluating chemical storage and containment procedures alongside maintenance managers.
In the afternoon, you could participate in cross-functional working sessions with project engineers to integrate circular economy criteria into asset renewal plans or draft action plans following a minor environmental anomaly. The day often concludes with preparing regulatory reporting or tailoring internal awareness briefings for frontline technicians.
What are the opportunities for professional growth and development in this role?
As a critical managerial function within the high-visibility Grand Paris Express program, success in this position opens strong internal progression tracks across RATP Group. You could advance toward senior QEHS management, group-level sustainability strategy, or director-level roles within infrastructure operations.
Given RATP’s vast international footprint through RATP Dev, opportunities also exist to export your infrastructure management and environmental expertise to international transit concessions and major capital rail projects worldwide.
The main stakeholders you might be interacting with
Internal stakeholders encompass operations and maintenance teams, infrastructure site directors, project managers, and the wider QEHS and CSR teams within RATP Infrastructures. You will work closely with site technicians, maintenance planners, and executive leadership to align ground practices with corporate policy.
Externally, you will frequently liaise with public bodies such as Société des Grands Projets (SGP), environmental inspection authorities (DREAL/DRIEAT), municipal agencies, and third-party contractors delivering maintenance, waste handling, or environmental remediation services.
