Role Description

We're looking for a Sr. DevOps Engineer to help reshape how our infrastructure and delivery pipelines are built - not just automating tasks, but engineering the platforms and AI-assisted tooling that let our engineers ship faster, safer, and with more confidence. You'll report to the DevOps Sr. Manager.

This isn't a "keep the lights on" role. You'll take real ownership of how our CI/CD and infrastructure evolve, with the autonomy to decide where AI-assisted tooling (copilots, LLM-driven diagnostics, intelligent automation) can remove toil and accelerate the software delivery lifecycle for the teams that depend on us. If you like turning messy, manual processes into reliable, self-service platforms, you'll feel at home here.

Location
Working at least 3 days a week from the office in Caesarea

What you will be doing:

• Operate and extend our Kubernetes and container-based platforms, orchestrating deployments across AWS.
• Own and evolve CI/CD pipelines spanning Debian packaging, container orchestration, and cloud-native deployments — increasingly augmented with AI-assisted testing, anomaly detection, and self-healing automation.
• Design and build Python modules, tools, and services that power our CI frameworks, packaging processes, and operational automation — with AI coding assistants (e.g., Claude Code, Copilot) as a standard part of your workflow for scaffolding, refactoring, and code review.
• Partner with development teams to diagnose and resolve complex issues across build systems, APIs, and dev environments, leveraging AI-assisted log analysis and root-cause tooling to cut time-to-resolution.
• Maintain and improve automated build/test pipelines using Jenkins and Argo Workflows.
• Apply infrastructure-as-code practices with Terraform, ArgoCD, and Helm to keep environments reproducible and easy to reason about.
• Explore and pilot AI-driven observability and incident-response tooling (e.g., anomaly detection on metrics/logs, automated runbook suggestions) to make our systems more self-diagnosing over time.
• Champion the use of AI/LLM tooling to eliminate manual, repetitive DevOps work — and share what works so the whole team levels up.

What you should have:

• 5+ years of experience as a DevOps Engineer in Linux environments
• 5+ years of Python development experience
• Hands-on expertise with Linux, Containers, Kubernetes, and AWS
• Strong proficiency in Shell scripting and CI/CD pipeline design
• Proven problem-solving ability and strong communication skills
• Experience leading Agile projects, including sprints and Scrum ceremonies
• Curiosity and hands-on comfort with AI-assisted development tools (Copilot, Claude Code, or similar) is a strong plus — we'll help you level up if you're new to them
