* Set up and administer Kubernetes and Docker Swarm clusters (infrastructure, storage, network, backup) for the client, ensuring high availability, performance, and resilience.
* Develop and automate deployments via Ansible and CI/CD (GitHub Actions, Azure DevOps), aligning client delivery practices with reliability and repeatability standards.
* Implement and manage observability platforms based on the Grafana LGMT stack (Mimir, Loki, Alertmanager, Alerta, Traefik) to ensure end-to-end visibility and proactive incident response at the client.
* Participate in the implementation of disaster recovery plans and in the migration of Linux environments (Ubuntu, Red Hat, CentOS) for the client's critical workloads.
* Collaborate with support and project management teams to guarantee the stability and performance of services across the client's environment.
Candidate Profile:
* Higher education in computer science (or equivalent by experience).

* Tackle challenges such as HA cluster design, DR orchestration, multi-tenant observability with Grafana LGMT, and robust CI/CD for infrastructure and applications.
Turbo-Charged Learning and Development:
* Access Keystone Solutions' coaching, certifications support (e.g., Kubernetes, cloud, automation), and knowledge-sharing guilds focused on SRE, Platform Engineering, and Observability.
* Benefit from peers' reusable blueprints (Ansible roles, GitHub Actions templates, Kubernetes add-ons) to accelerate delivery at client sites.
Ambition Skyrocketing within a Consultancy Framework:
* Shape your career through varied client engagements: lead migrations, formalize DR runbooks, introduce GitOps, or mentor client teams on platform standards.
* Progress from delivery ownership to technical leadership while Keystone Solutions supports you with mission planning and career pathway mapping.
Keystone Solutions Values in a Consultancy Context:

* Curiosity and integrity: challenge assumptions, uphold best practices, and document clearly.
Consulting Impact for the Systems/DevOps Engineer:
* Apply deep expertise in Kubernetes, Nutanix/VMware, and CI/CD to design highly available platforms tailored to each client's constraints (storage, networking, security, backup).
* Implement unified observability leveraging Grafana LGMT (Mimir, Loki, Alertmanager, Alerta, Traefik) plus Prometheus/Tempo to enable proactive reliability management.
* Automate end-to-end with Ansible and pipelines (GitHub Actions, Azure DevOps), standardizing builds, releases, and infrastructure changes.
* Drive Linux migrations (Ubuntu, Red Hat, CentOS) and formalize disaster recovery strategies with testable runbooks and recovery objectives.
* Partner with support and project management to maintain SLA/SLO compliance and continuous service improvement.
Interview Questions for This Mission:
* Describe how you would set up a highly available Kubernetes platform on Nutanix or VMware, detailing the storage, networking, monitoring, and CI/CD aspects.
* Provide a concrete example of a project where you automated a complex deployment or migration (for example with Ansible or a CI/CD pipeline). What challenges did you face and how did you resolve them?
