NTT Data is currently looking for a System Engineer for one of our clients in the public sector based in Brussels. The role is performed in a hybrid role.
Job Description: The organisation is working on the development of an Internal Developer Platform (IDP), including the associated platform services, with the goal of supporting development teams by providing them with a modern, efficient, and secure development environment. This platform is set up according to the "platform-as-a-product" principle and represents a strategic initiative within Enterprise IT Services (EITS).
Role:
As a Platform Engineer, you are part of the team responsible for the further development of the IDP and related platform services. You contribute to the design, implementation, and maintenance of a platform where self-service, automation, and an optimal developer experience are central. In this role, you work closely with developers, security, operations, and architects to deliver a robust and scalable environment.
Assignment Description
The assignment has three equally important objectives:
- Expanding and professionalizing the OpenShift platform into a stable, scalable, and reusable platform capability.
- Increasing Kubernetes maturity within application teams through enablement, guidance, and the provision of clear platform mechanisms.
- Embedding platform engineering principles into daily operations, both technically and organizationally, in close collaboration with architecture and product management.
The assignment is product- and capability-driven.
Core Tasks and Responsibilities
Expansion and Operationalization of the OpenShift Platform
As a Senior Platform Engineer, you are responsible for:
- Designing, implementing, and refining the OpenShift cluster architecture, including multi-environment setup, security, networking, storage, and lifecycle management.
- Building reusable platform building blocks, such as standard namespaces, policies, base Helm charts/operators, and standardized deployment and runtime patterns.
- Developing a GitOps-first approach using Argo CD for platform and application configuration.
- Ensuring the stability, maintainability, and evolvability of the platform, including upgrades, versioning, and lifecycle management.
- Establishing collaboration with EITS domains (such as networking, security, observability, and databases) to correctly integrate platform capabilities.
Platform Enablement and Increasing Application Team Maturity
In this role, you guide application teams in:
- Containerization challenges and Kubernetes deployments.
- Correct integration with platform services such as CI/CD, IAM, observability, and secrets.
- The evolution of teams from "containers as an infrastructure detail" to "Kubernetes as a standardized runtime."
- Jointly developing golden paths and opinionated defaults that provide guidance without enforcing a one-size-fits-all approach.
- Contributing to documentation, templates, and self-service flows via Backstage and Git.
- Coaching teams on ownership thinking ("you build it, you run it") within the boundaries of the platform.
Platform Engineering Culture and Collaboration
As a Senior Platform Engineer, you:
- Work closely with platform engineering, product management, and architecture.
- Act according to the platform-as-a-product principle.
- Collect user feedback and focus on scalability and repeatability, avoiding team-specific customization.
- Break down silos between infrastructure, platform, and application development.
- Contribute to clear responsibilities, realistic expectations, and strengthening trust in the platform.
Expected Results
- A more stable and consistent OpenShift platform with clear standards.
- Application teams that can work more independently with Kubernetes concepts.
- Fewer ad-hoc solutions and more reuse within the platform.
- Platform mechanisms that are well-documented, easy to find, and repeatable.
- Increased trust between platform, infrastructure, and application development.
Profile:
- Bachelor's or Master's degree in IT, or equivalent experience.
- Proven experience in platform engineering and DevOps.
- Strong knowledge of container technologies such as Docker and Kubernetes.
- Experience with CI/CD tools (GitLab CI, Jenkins, Argo CD, etc.).
- Knowledge of cloud-native technologies such as Helm, Prometheus, and Grafana.
- Experience with scripting and automation (e.g., Bash, Python, Terraform).
- A team player with a product mindset and an eye for developer experience and change management.
- Certification in platform engineering is a plus.
- Experience working in a government or regulated environment is a plus.
Languages:
- Proficiency in Dutch or French, with passive knowledge of the other national language and English.
