Senior Network Site Reliability Engineer – NetSRE

Jobtailor; Deutschland; Vor Ort; EUR 85.000 - 110.000; Vollzeit

Zusammenfassung

Jobtailor is seeking a reliability-focused engineer in Germany to own service SLIs/SLOs, incident response, and post‑mortems. You will drive observability, design safe change workflows, and partner with network engineers to embed operability into designs.

You should bring strong Linux fundamentals, networking knowledge, and hands-on HA experience, plus ability to automate with Go or Python and use modern IaC/CI‑CD tooling to streamline operations.

Qualifikationen

• Strong production Linux fundamentals and structured debugging of complex systems.
• Solid understanding of networking basics and failure modes.
• Experience operating high-availability systems and driving improvements.
• Ability to write and maintain software/automation (Go or Python).
• Experience with modern infrastructure tooling (IaC, CI/CD, containers).

Aufgaben

• Define and own reliability goals for network services and critical paths (SLIs/SLOs, availability targets, error budgets).
• Drive reliability improvements across the whole network: services, site readiness, inter-site connectivity, and operational standards.
• Own incident response for your areas, lead investigations/post-mortems, and implement durable fixes.
• Build and evolve observability: metrics/logs/traces, alerts, and faster debug loops during incidents.
• Design safer change workflows: automation, CI/CD, test/staging environments, canarying, rollbacks, and auditability for network changes.
• Work closely with network engineers and platform teams to embed operability into designs.

Jobbeschreibung

Responsibilities

• Define and own reliability goals for network services and critical paths (SLIs/SLOs, availability targets, error budgets where it makes sense)
• Drive reliability improvements across the whole network: not only services, but also site readiness, inter‑site connectivity (DCI), and operational standards
• Own incident response for your areas, lead investigations/post‑mortems, and turn failures into durable fixes (not repeated firefighting)
• Build and evolve observability: actionable metrics/logs/traces, alerting, and faster debug loops during and after incidents
• Design safer change workflows: automation, CI/CD, test/staging environments, canarying, rollbacks, and auditability for network changes
• Work closely with network engineers and platform teams to embed operability into designs and keep operations practical and fast

Requirements

• Strong production Linux fundamentals and a structured approach to debugging complex systems
• Solid understanding of networking basics and how real networks fail (control plane vs data plane, latency/loss, failure domains, etc.)
• Hands‑on experience operating high‑availability systems and improving them over time (not just "keeping lights on")
• Ability to write and maintain software/automation (Go is common for us; Python is also welcome)
• Experience with modern infrastructure tooling (e.g., IaC, CI/CD, container platforms) and comfort automating operational workflows
