Position overview

We’re seeking a Senior Platform Reliability Engineer to keep our Kubernetes-centric provisioning and Linux estate running smoothly. You’ll coordinate fixes when OS builds or upgrades hit exceptions working across teams to find root causes from logs/metrics and recommend changes.

You’ll automate repeat work (Bash/Python), strengthen runbooks and observability, and document configurations and procedures. You’ll be partnering with hands-on engineers and architects in a highly technical, delivery-focused environment.

Responsibilities

• Operate and improve a Kubernetes-centric, open-source platform across provisioning and maintenance workflows.
• Coordinate resolution of exceptions in a multi-stage (≈10) provisioning pipeline; engage the right owners with clear, actionable context.
• Build and maintain automation and runbooks (Bash/Python) to reduce toil and increase reliability.
• Lead triage, log analysis, and root-cause investigation to minimize downtime.
• Enhance observability (metrics/logs/traces) and promote SLO-oriented practices.
• Operate and tune distributed data stores (e.g., Cassandra) and platform services.
• Evolve OS/network provisioning (PXE boot, Subiquity, Foreman, imaging) and server management (BMCs, multi-NIC).
• Partner with platform teams to improve automation, performance, security, and cost efficiency.
• Document system configurations, procedures, and changes for repeatability.

Requirements

• Strong Linux administration and troubleshooting (Ubuntu/Debian preferred).
• Production experience with Kubernetes (or similar orchestrator).
• Hands-on network/OS provisioning (PXE, Foreman, Subiquity, imaging) and server hardware management (BMCs, multiple NICs).
• Proficiency in scripting (Bash, Python) for automation and diagnostics.
• Ability to debug across the stack (infrastructure, workloads, automation, networks) and deliver RCA.
• Experience with distributed databases (Cassandra or similar).
• Familiarity with runbooks, incident management, and SRE/reliability practices.
• Clear communicator and process facilitator: knows whom to engage, what signals to collect, and how to drive issues to closure.
• CI/CD and IaC mindset (Git and pipelines; Terraform/Ansible a plus).

Nice to have

• Observability stacks (Prometheus, Grafana, ELK/EFK, OpenTelemetry).
• Workflow systems and retry logic (Argo Workflows, Jenkins).
• Python for internal tooling (Go a plus).
• Distributed systems fundamentals (consistency, replication, partition tolerance).
• Experience operating Cassandra at scale.
• Experience with Agile development methodologies.
• Experience working with foreign clients.
