Lead Data & AI Architect, FR

The Lead Architect plays a pivotal role at vector8. You will define, design, and build enterprise-grade data and AI solutions for some of the most complex organisations in France. You are not only an architect, but you are also a hands‑on solution designer and occasional coder who shapes systems and guides teams through implementation.

You bring deep expertise in enterprise and solution architecture for data and AI, combined with the willingness and ability to dive into code, validate architectural decisions, and help delivery teams move forward. You are comfortable navigating complex system landscapes, legacy environments, and strict requirements around security, compliance, and data protection.

In close partnership with vector8’s Principal Cloud & Enterprise Architect, you co‑design the cloud, data, and AI foundations that enable organisations to scale AI from individual use cases to a sustainable, enterprise‑wide capability.

The role is based primarily in France, with travel to client sites and collaboration with teams across Europe.

Job requirements

Extensive and demonstrable experience in data engineering, AI solution architecture, and enterprise architecture.

Deep expertise in designing and building complex AI solutions (MLOps, streaming, APIs, orchestration).

Strong hands‑on engineering skills – comfortable coding in Python, SQL, or similar languages and working with modern data/AI toolchains.

Strong understanding of hybrid architectures combining on‑prem systems with cloud data and AI services.

Experience with at least one cloud provider: AWS, Azure, or GCP; multi‑cloud familiarity is a big plus.

Experience optimising cost, security, and scalability in cloud deployments.

Knowledge of data governance, responsible AI, security frameworks, and operational controls, ideally coupled with experience in highly regulated industries with strict requirements for security, privacy, compliance, and data governance.

Excellent stakeholder‑management and communication skills, able to influence both executives and engineering teams.

Ability to convert complex challenges into clear architectural decisions and actionable delivery plans.

Bachelor’s or Master’s degree in Computer Science, Mathematics, Physics or a related field.

You are fully proficient in both French and English, with German considered a valuable plus.

Willingness to travel within France and occasionally to European delivery hubs.
