1. The Hook & Strategic Vision

«The future of modern Information System and Data protection is being built right here, at the crossroads of Cloud, Web applications, and Artificial Intelligence.»

The traditional «moat-and-castle» security model of the past has been rendered obsolete. With a mature, public cloud-native and SaaS-first strategy, Veolia Group DB&T is driving a shift to Zero Trust that unleashes the cloud's full potential: rather than relying on heavy perimetric network overlays, we secure each component of the digital chain: Identity, Devices, Transport, Applications, and Data Access.

We are looking for a visionary Cloud Architect to lead this transition and support the global Zero Trust roadmap for a world leader in ecological transformation.

2. The Value Proposition

- Global Impact: Directly protect the digital ecosystem enabling Veolia's ecological transformation. By aligning security with strategic business stakes, you will make digital trust an accelerator of ecological solutions and safeguard the water, waste, and energy solutions of tomorrow.

- Architectural Agility: Design custom, adaptive security postures that match the actual maturity and criticality of each environment—leveraging modern browser-level Zero Trust for high-speed cloud business, while pragmatically securing legacy and OT scopes. Orchestrate safe growth, instead of enforcing static checklists.

- Synergy and rationalisation: Rationalize and simplify our global protection stack—reducing architectural complexity, eliminating redundant tools, and co-designing elegant, unified standards—by federating and animating a vibrant international community of Zero Trust contributors and experts across our Business Units. Turn our technical diversity into a streamlined strength!

3. The Core Missions

Strategy Definition & Secure-by-Design Architecture

Act as the senior technical referee. You will define, validate, and promote the Zero Trust architecture blueprint across Group teams and global BUs. You will steer technical choices away from legacy, network-dependent constraints and advocate for modern identity-centric, browser-enforced, and resource-level controls.

Cyberlab Leadership & Prototyping

Lead the technology watch and build practical proof-of-concepts (PoCs) within our Cyberlab. This involves validating advanced solutions and determining their fit for Veolia's maturity and scopes criticality.

For instance, you will have to consider the protection of AI components (LLMs, generative AI, and autonomous agents) as well as develop specific integration models (such as SASE/ZTNA) designed exclusively to securely integrate legacy software and OT/SCADA environments into our trust framework.

Global Support for Business Units (BUs)

Democratize Zero Trust and native protection of our assets. You will build and publish reusable «blueprints», starter kits, and architectural templates to facilitate easy migration paths for local teams.

When local BUs face unique architectural hurdles, you will use your pragmatism and expertise to design secure workarounds, ensuring security acts as an enabler to business delivery rather than a blocker.

The Design & Legal Assessment (DLA)

Contribute as an expert to the DLA process to support DLA team in evaluating and auditing newly introduced or renewed Group solutions (SaaS, PaaS, Mobile, and complex multi-cloud deployments).
