Platform Engineer

Platform Engineer (Freelance) - 5 months - Brussels Belgium

Where Builders Build the Future

At RELYzIT Talent, we don’t recruit — we build. We unite the top 2% of builders — engineers, architects, creators — into a movement across Europe and the GCC. Vetted through our VECTOR7™ Signal Stack, you’re not just hired, you’re chosen. This is more than work. This is where builders build the future.

We are seeking a Platform Engineer (Freelance) for a 5-month engagement with our client in Brussels. This is your opportunity to architect, automate, and empower teams at scale — shaping the very foundations that enable innovation.

Why This Role Matters

As a Platform Engineer, you will be the force multiplier for development teams, accelerating delivery and raising the bar for security, reliability, and automation. Your work will directly impact how software is built, tested, and shipped — ensuring our client’s teams can focus on what matters: building products that move the business forward. The stakes are high: your expertise will drive consistency, compliance, and velocity across the organization.

What You’ll Be Doing

• Designing, building, and maintaining Azure Kubernetes Service (AKS) clusters — including node pool configuration, networking, ingress, autoscaling, and confidential compute workloads.


• Managing and evolving the Azure cloud platform: subscriptions, resource groups, Key Vault, Azure Container Registry, Service Bus, Storage Accounts, and SQL databases.


• Operating and supporting OpenShift environments where applicable.


• Ensuring platform security, reliability, and compliance with organizational standards (network policies, managed identities, TLS, RBAC).


• Developing and maintaining shared, reusable CI/CD pipeline templates (YAML) in Azure DevOps, consumed by all application repositories.


• Building and optimizing multi-stage deployment pipelines for .NET 8 applications, including container image builds (Docker/ACR), database deployments (DACPAC/sqlpackage), and Service Bus provisioning.


• Authoring and maintaining PowerShell Core 7+ modules and scripts for pipeline logic, configuration generation, deployment map parsing, secret retrieval, Terraform variable construction, and Helm-based deployments.


• Enforcing security, quality gates (SonarQube), and environment promotion controls (DEV → TST → VAL → Manual Gate → PRD) within pipelines.


• Standardizing deployment patterns for consistent, auditable release workflows across all project teams.


• Designing, authoring, and maintaining Terraform modules for provisioning and configuring Azure resources, including AKS workloads, Keycloak identity clients, SQL users, managed identities, Key Vault HSM keys, and Service Bus RBAC.


• Automating provisioning, scaling, and lifecycle management of infrastructure resources using Terraform, Azure CLI, and PowerShell.


• Managing Terraform state (Azure Storage backend with AAD auth) for safe, repeatable deployments across environments.


• Administering shared Common/devops repositories and deployment configuration repositories.


• Supporting version control practices, branching strategy (GitFlow: DEV/MAIN/hotfix), and PR validation workflows.


• Managing Azure DevOps service connections, agent pools, variable groups, and environment approvals.


• Serving as the bridge between infrastructure and application development teams, enabling integration of platform capabilities into workflows.


• Providing guidance and support on platform standards, deployment map configuration, pipeline extension patterns, and troubleshooting.


• Writing and maintaining documentation (README, schema references, onboarding guides) for consuming teams.


• Reviewing contributions to shared platform code for architectural consistency and backward compatibility.

What We’re Looking For

• Hands-on experience operating and configuring Azure Kubernetes Service (AKS) — networking, ingress, node pools, autoscaling, confidential compute, Helm chart deployments.


• Strong understanding of DevOps practices: CI/CD principles, GitFlow branching, environment promotion, and deployment automation.


• Familiarity with .NET 10 build toolchain (dotnet build), NuGet, solution/project structure, and containerizing .NET applications.


• Proficiency in PowerShell Core 7+ — writing modules (.psm1), classes, Pester 5+ tests, and robust scripting with proper error handling.


• Broad experience with Azure services: Key Vault, Container Registry, Service Bus, Storage Accounts, SQL Database, Managed Identities, RBAC.


• Understanding of cloud architecture principles — scalability, high availability, security, cost management.


• Experience with Azure DevOps (TFS) — YAML pipelines, extends templates, repositories, service connections, agent pools, artifacts.


• Ability to author and maintain multi-stage YAML pipeline templates with parameterization, conditions, and template composition.


• Experience writing and maintaining Terraform configurations — modules, providers (azurerm, helm, keycloak, mssql, kubernetes), state management, plan/apply workflows.


• Understanding of network concepts relevant to AKS and Azure — VNets, NSGs, private endpoints, DNS, ingress controllers, proxy configuration.


• Ability to reason about system architecture — separation of concerns, shared platform design, module boundaries, and extensibility.

Nice to Have

• Experience with Keycloak or OpenID Connect identity management.


• Familiarity with Docker and container image build optimization.


• Knowledge of database deployment automation (DACPAC, sqlpackage).


• Experience with SonarQube or similar code quality tooling.


• Familiarity with confidential computing on Azure.


• Experience with OpenShift container platform.
