Why your role matters

As a Senior Platform Engineer (Kubernetes), you will be crucial in designing, implementing, and maintaining our on-prem platform infrastructure, with a primary focus on our private cloud, particularly Kubernetes orchestration and containerization. While Kubernetes will be a key area of focus, you will also work across various middleware and infrastructure technologies. You will collaborate closely with internal stakeholders to enhance our platform’s reliability, scalability, and overall user experience, driving innovation and best practices in the platform engineering domain.

You will support and help lead the architectural design and implementation of our internal Kubernetes cluster (IKS - i3D Kubernetes Service), which we currently use internally and plan to offer to external customers in the future. It’s important to think about the product in a way that makes sure our solutions not only work for today but can also scale and evolve as we grow.

Key Responsibilities

• Design and Build Platform Features: You’ll develop new platform features, making sure they’re scalable, reliable, and work smoothly across middleware components like Kubernetes. You’ll also play a big part in shaping and building out our internal Kubernetes cluster (IKS).

• Automate and Optimize Infrastructure: You’ll automate the setup and management of infrastructure, improving the performance and efficiency of systems like databases, web servers, and message queues.

• CI/CD Pipeline Development: You’ll create and maintain CI/CD pipelines that help keep our development process smooth and efficient, enabling continuous integration and delivery across different environments.

• Monitor and Log Platform Health: You’ll implement and manage monitoring and logging solutions to make sure everything’s running smoothly, using tools like Prometheus, Grafana, and others.

• Collaborate on Platform Strategy: You’ll work closely with other teams to make sure the platform engineering strategies align with business goals and the overall product roadmap.

• Ensure Security and Compliance: You’ll put security best practices into action and ensure that we meet all relevant standards and regulations to keep our platform safe and sound.

• Promote DevOps and GitOps Practices: You’ll advocate for DevOps and GitOps practices, helping create a culture of continuous improvement and operational excellence across the team.

• Mentorship and Knowledge Sharing: You’ll mentor junior engineers and share your knowledge with the team, encouraging best practices and a focus on learning and growth.

Tech stack

At i3D.net, you’ll work with:

• Languages: Golang (primary), PHP (legacy), .NET

• Infrastructure & Tools: Docker, Kubernetes, Ansible, GitLab pipelines, OpenSearch

• Databases: MariaDB

• Practices: Test-Driven Development (TDD), CI/CD pipelines, Agile methodologies—we follow a "you build it, you deploy it, you support it" philosophy

What success looks like in the first year

• You’ve made our Kubernetes cluster, and platform features more reliable, efficient, and scalable.

• You’ve automated tasks and streamlined systems to reduce overhead.

• You’ve contributed to the platform’s direction and future roadmap.

• You’ve put security first with solid measures that meet industry standards.

• You’ve mentored junior engineers and helped build a more collaborative team.

About you

• Kubernetes Expertise: Direct experience running and maintaining self-hosted Kubernetes clusters, including upgrades, scaling, troubleshooting, and working on cluster networking and control plane components. Experience with on-prem or bare metal environments (for example, Talos or other container-optimized operating systems) is a big plus.

• Networking Solutions: Proficient in Kubernetes networking, using tools like Cilium or Calico, with a focus on security and policy management.

• GitOps Experience: Hands-on experience with GitOps workflows, particularly with Argo CD for automated delivery.

• CI/CD Knowledge: Familiar with GitLab CI/CD or similar platforms for building and deploying containerized workloads.

• Security and Compliance: Strong understanding of security best practices and compliance in on-prem environments.

• Collaboration & Mentorship: Passion for working in teams, sharing knowledge, and helping others grow.

• Remote vs Onsite: This is a hybrid role, so you'll spend some time working onsite at our Rotterdam office. If you're already in the Netherlands, great! If not, we're happy to support your move with our relocation services (a valid EU work permit is required).
