Job summary

Sia is seeking an experienced Solution Architect to join its AI Platforms team in Paris. You will be the technical authority on client engagements, translating business requirements into robust data and AI architectures across cloud, ML, and generative AI domains.

You will work with senior stakeholders to define vision, remove delivery impediments, and ensure architectural choices meet security, compliance, and cost constraints.

Qualifications

• Master's degree in computer science, engineering, or a related field.
• 5 to 8 years of experience in solution architecture, cloud architecture, or a senior engineering role with significant design responsibilities.
• Deep expertise in at least two of the following technology ecosystems: AWS, Microsoft Azure, Google Cloud Platform, Databricks, OpenAI, Anthropic, NVIDIA.
• Strong command of cloud architecture patterns — networking, security, compute, storage, and managed AI/ML services.
• Solid understanding of the data and AI landscape: classical ML, deep learning, generative AI, autonomous agents, and data engineering.
• Proven ability to engage with senior client stakeholders (CIO, CISO, VP Engineering) and translate business needs into technical solutions.
• Excellent communication and presentation skills — able to convey complex technical concepts to both technical and non‑technical audiences.
• Fluent in French; professional proficiency in English.

Responsibilities

• Define and own the end‑to‑end technical architecture for data and AI projects — covering cloud infrastructure, data pipelines, ML/DL model serving, generative AI applications, and agent‑based systems.
• Act as the primary technical point of contact for client stakeholders, aligning architectural decisions with business objectives, security policies, and regulatory requirements (GDPR, EU AI Act).
• Lead architecture reviews, design sessions, and technical governance forums to ensure quality and coherence across workstreams.
• Remove technical impediments for engineering teams and provide hands‑on guidance when needed.
• Oversee the full project lifecycle: from advisory and assessments through prototyping (POC/MVP) to full‑scale production deployment.
• Ensure solutions are designed for production readiness — addressing scalability, reliability, observability, and cost optimization.
• Support business development by contributing to technical scoping, architecture proposals, and effort estimations during the sales cycle.
• Participate in client presentations and workshops to demonstrate Sia’s technical capabilities and build trust.
• Identify expansion opportunities within existing accounts by surfacing new use cases and technical needs.
• Mentor junior consultants and engineers, helping them grow their architectural thinking and client‑facing skills.
• Contribute to building internal IP, accelerators, and reference architectures that leverage frontier technological developments.
• Stay current on the evolving landscape of cloud services, AI frameworks, and industry best practices.
