About the job

As AWS Cloud Engineer within our Cloud Engineering team, you'll design and build the cloud foundation that powers Sanofi's most critical solutions. From evolving our AWS Landing Zone to enabling teams across the organization to leverage cloud at scale, you'll be a key enabler of innovation — championing infrastructure-as-code practices and engineering excellence every step of the way. Ready to get started?

Our Cloud Engineering team is made up of passionate cloud experts who own the AWS Landing Zone and its foundational services. We work hand-in-hand with infrastructure and application teams, supporting cloud migration journeys and helping build cloud-native solutions. It's a collaborative, forward-thinking environment where your ideas shape how a global biopharma company harnesses the power of the cloud.

Main responsibilities

• Design and build cloud foundations — Own the AWS Landing Zone and core cloud services, ensuring they are secure, scalable, and ready to support business-critical workloads (400 AWS accounts).
• Develop reusable infrastructure components — Write and maintain modular infrastructure-as-code using Terraform, building a library of standardised, reusable modules that accelerate delivery across teams.
• Automate deployments end-to-end — Create and maintain CI/CD pipelines to automate cloud provisioning, configuration management, and service deployment reliably and at scale.
• Embed security and compliance by design — Implement cloud security controls, access policies, and network safeguards to ensure every deployment meets Sanofi's standards and regulatory requirements.
• Keep the platform visible and reliable — Set up monitoring, logging, and alerting solutions so teams have full visibility into platform health and can respond quickly when issues arise.
• Contribute to cloud migration initiatives — Guide the migration of on-premises workloads to AWS, minimizing disruption while applying cloud architecture best practices throughout.
• Enable and uplift cloud capability — Act as a trusted technical advisor for engineering teams, sharing knowledge on cloud patterns, best practices, and tools to raise the bar across the organisation.

About you

• Cloud expertise — Deep, hands-on experience with AWS services and cloud architecture, with a strong ability to design scalable and resilient solutions.
• Infrastructure as code mindset — Strong proficiency in Terraform (including module development), CI/CD pipelines (GitHub Actions preferred), and automation tooling such as Ansible.
• Security and networking know-how — Solid understanding of AWS security principles, IAM, networking concepts, and compliance controls.
• Collaborative and communicative — You thrive in cross-functional environments, can explain complex technical concepts clearly, and enjoy helping others grow their cloud skills.
• Engineering excellence advocate — You treat infrastructure like software — tested, versioned, and continuously improved — and bring a DevOps culture wherever you go.
• Nice to have — AWS certifications and/or hands-on experience leading cloud migration projects are a plus.
