This is a remote position.
Job Title: Senior Kubernetes Specialist
Location: Portugal
Work Regime: Full-time & Remote
Overview / Summary:
We are looking for an experienced Senior Kubernetes Specialist to lead the design, implementation, and management of our containerized infrastructure. The ideal candidate is not just a user of Kubernetes, but a deep specialist capable of architecting complex, scalable, and secure clusters. While the core focus is on Kubernetes mastery, we are specifically seeking candidates with experience in Red Hat Openshift (OKD), Google Cloud Platform (GCP) and Hybrid Cloud environments (connecting onpremises infrastructure with public cloud).
Responsibilities and Tasks:
- Cluster Architecture & Management: Design, deploy, and maintain high-availability Kubernetes clusters in production environments.
- Infrastructure as Code (IaC): Automate infrastructure provisioning using tools like Terraform, Ansible, or Crossplane.
- Hybrid Connectivity: Manage networking, latency, and security challenges between on-premise data centers and cloud environments.
- Security & Compliance: Implement best practices for cluster security, including RBAC, network policies, secrets management, and container scanning.
- Observability: Design robust monitoring, logging, and alerting strategies (Prometheus, Grafana, ELK/EFK stack).
- CI/CD Integration: Build and optimize pipelines for seamless container deployment (GitHub Actions, ArgoCD, Atlantis).
- Migration: Act as a pinpoint in various application migrations from OKD to GKE/k0s, handling the specifics of each application and managing the various keyplayers.
Requirements
Mandatory Requirements:
- Experience: 5+ years in DevOps/SRE roles, with at least 3+ years of hands-on experience managing production Kubernetes clusters.
- Deep K8s Knowledge: Proven expertise in Kubernetes internals (etcd, API server, controllers, schedulers) and troubleshooting complex cluster issues.
- Containerization: Knowledgeable of Docker/Containerd/Podman runtimes and image optimization.
- Scripting & Automation: Some proficiency in a programming or scripting language, like Python, Go, or Bash/ZSH/Fish scripting.
- OKD: Some knowledge in Openshift environments, knowing where RedHat took some opinionated options towards kubernetes
Complementary Requirements:
- GCP Specialization: Experience with GKE (Google Kubernetes Engine) and GCP networking (VPC, Cloud Interconnect, Cloud NAT).
- Hybrid/Multi-Cloud: Experience managing hybrid infrastructure, ideally using tools like RKE or k0smotron, and managing connectivity between on-premises hardware and public cloud.
- Certifications: CKA (Certified Kubernetes Administrator) or CKAD (Certified Kubernetes Application Developer).
Soft Skills & Culture Fit:
- Problem Solver: A "fixer" mentality—someone who digs deep into root causes rather than applying band-aid solutions.
- Communication: Ability to explain complex infrastructure decisions to stakeholders and developers, ability to handle various levels of skills and understand lacks in knowledge on the audience, adapting the discourse.
- Adaptability: Comfortable working in environments where legacy on-prem systems must coexist with modern cloud architecture.
