Site Reliability Engineer

At Thales, trust is the foundation of the digital world. Our Digital Identity & Security (DIS) division helps businesses and governments protect identities and secure digital interactions. Within DIS, the On-Demand Connectivity (ODC) business line plays a pivotal role in powering secure eSIM technology, enabling seamless, remote connectivity for devices around the globe.
With eSIM solutions, you would help companies in deploying IoT devices, manage remote workforces, and launch connected products without the delays and logistics of physical SIM cards. Imagine logistics fleets updating routes on the fly, smart factories remotely optimizing production lines, or wearables connecting instantly to local networks during international travel—all with zero physical intervention.

We’re looking for a Site Reliability Engineer (SRE) who thrives in both application-level problem-solving and infrastructure design. This role is about more than just keeping systems running — it’s about applying software engineering practices to make our ODC applications more reliable, scalable, and performant in a cloud-native, production-grade environment.

What You’ll Do

As part of the SRE team within Thales ODC, you'll be instrumental in bridging the gap between application development and operations.

You will:

• Work in a DevOps environment, supporting ODC products running on Google Cloud Platform (GCP), with a focus on applying SRE principles for reliability and automation.
• Take ownership of both applications and infrastructure, ensuring the availability, performance, and scalability of our cloud-based services.
• Develop and maintain Infrastructure-as-Code (IaC) and automation pipelines using tools like Terraform, Helm, and GitLab CI/CD.
• Collaborate with development teams to enhance product reliability using a “you build it, you run it” mindset.
• Act as a key technical voice during Change Advisory Board (CAB) reviews for high-impact changes, providing Tier II expertise.
• Manage real-time system monitoring and drive continuous improvements in observability and alerting.
• Support the end-to-end deployment of ODC applications in the cloud — from design and configuration to rollout and performance tuning.
• Perform operational readiness reviews and shape product roadmaps with a focus on stability and scalability.
• Guide technical documentation, incident response processes, and SLA compliance across tiers.
• Participate in on-call support rotations (24/7) to ensure production systems remain resilient.

What You Bring:

• A degree in Computer Science or a related technical field.
• 4+ years of experience with application deployment, system operations, and cloud infrastructure.

Proficiency with:

• GCP services and Kubernetes in production environments
• Automation tools like GitLab, Terraform, Helm
• Linux systems, networking, and HTTP(S)/TCP/IP protocols
• Scripting languages like Shell or Python
• Experience with Agile methodologies and a DevOps/SRE mindset.
• A strong understanding of CI/CD pipelines, system integration, and monitoring tools.
• Ability to translate business requirements into scalable technical solutions

Preferred qualifications:

• GCP and/or Kubernetes certifications
• Experience in the Telecom domain or with eSIM technologies
• Familiarity with Scrum, incident management, and service delivery frameworks

Why Thales?

• Be part of a mission-critical team enhancing the future of connected technology.
• Work on cutting-edge applications that impact millions of users worldwide.
• Collaborate in a global, agile environment where your voice and ideas matter.
• Take ownership of solutions across the full lifecycle — from build to run — and be empowered to drive meaningful change.

At Thales, we don’t just operate infrastructure — we engineer it to support applications that keep the digital world connected and secure. If you're passionate about reliability, automation, and cloud-native applications, we invite you to apply and be part of our journey.
