Thales in the Czech Republic employs over 400 people from 45 different nationalities. A total of 15 teams work on projects for government agencies, banking, mobile services and the Internet Of Things (IoT) technology. At the core of our business is the development of software which we configure and embed in a multitude of different devices and form factors. These include many kinds of payment cards, SIM cards, travel passes, secure eBanking devices, authentication tokens, machine identification modules (MIM), and secure ID documents including ePassports, eID and eHealth cards, as well as eDriving licenses. Because of the international environment surrounding us every day, it comes as no surprise that English is our official corporate language.

We are seeking a versatile Platform DevOps Engineer to join a team that sits at the intersection of product development and field deployment. Our team is responsible for the core platform as a product that enables our cloud-native products to run reliably in customer data centers specifically optimized for offline/air-gapped scenarios.

This is a dynamic, collaborative role where you will act as a technical enabler for our development and deployment teams. You will contribute to the evolution of our core platform, maintain our internal Platform-as-a-Service (PaaS) infrastructure and support production deployments.

Key Responsibilities:

• Production & Deployment Support: Act as a technical subject matter expert during critical deployment phases. This role could involve occasional travel to delivery center locations to provide hands-on support for production deployments, ensuring platform integrity and reliability in customer environments.
• Platform Development: Contribute to the engineering and maintenance of our core platform, built on Kubernetes and supported by an ecosystem of open-source components (e.g., logging, monitoring, managed databases, and message queues).
• Internal PaaS Management: Administer, automate, and evolve our internal Proxmox-based Platform-as-a-Service (PaaS), ensuring R&D teams have robust, scalable infrastructure.
• Engineering Support & Troubleshooting: Act as a bridge to product teams by analyzing complex service interactions. You will debug and optimize application performance by leveraging your understanding of protocol-level behaviors (e.g., messaging queues, database connections, and authentication flows like OIDC).
• Pipeline & Delivery Automation: Maintain CI/CD pipelines (GitLab CI) and support our platform delivery mechanisms, utilizing GitOps practices (such as Flux) to ensure consistency across environments.

Core Technical Requirements:

• Kubernetes & Storage: Deep experience in Kubernetes orchestration, with a understanding of Kubernetes storage concepts, Networking and workload distribution
• Infrastructure Automation: Experience with Ansible and Python for configuration management and orchestration.
• Protocol & Service Understanding: Ability to debug at the protocol level (Message Queues, Databases, OIDC/Authentication flows, etc.).
• Databases & Observability: Experience in Relational Database configuration (e.g., MySQL) and cluster monitoring/alerting (e.g., Prometheus, Grafana, ELK).
• OS & Virtualization: Solid foundation in Linux administration and experience with virtualizationtechnologies (Proxmox).
• CI/CD & GitOps: Familiarity with GitLab for CI/CD and experience with modern deployment tooling (e.g., Flux).
