Sr. Network Site Reliability Engineer (SREs)

We provide end-to-end IT solutions and services including Applications services, Data & Analytics services, AI/ML Technologies and Professional services in the UK and EU market.

Job Description

Overview

We are seeking a highly experienced Senior Network SRE with deep expertise across multi-vendor network infrastructure, automation, and reliability engineering. The ideal candidate will possess strong technical leadership, hands-on engineering capabilities, and a passion for building resilient, scalable, and observable network environments.

Key Responsibilities

• Design, implement, and maintain highly available network solutions across routing, switching, firewalling, and wireless technologies.
• Apply SRE principles to improve network reliability, scalability, and performance.
• Develop and maintain automation workflows using Ansible, Salt, and related frameworks to reduce operational toil.
• Build and operate monitoring, alerting, and observability dashboards using tools such as Grafana and Splunk.
• Proactively identify network bottlenecks, performance issues, and reliability risks, implementing long-term fixes rather than reactive solutions.
• Support incident response, root cause analysis, and post-incident reviews with a focus on continuous improvement.
• Collaborate with cross-functional engineering, security, and operations teams to ensure network solutions meet business and technical requirements.
• Contribute to documentation, runbooks, design artifacts, and operational standards.
• Participate in capacity planning, network modernization initiatives, and automation-first strategies.

Required Skills & Experience

• 10+ years of hands-on experience in enterprise or service provider network engineering.
• Expertise in multi-vendor routing, switching, firewalling, and wireless technologies.
• Deep understanding of network protocols (BGP, OSPF, EIGRP, STP, VXLAN, VPNs, QoS, MPLS, etc.).
• Strong experience with infrastructure automation using Ansible and Salt.
• Proficiency with observability tooling such as Grafana, Splunk, or equivalent.
• Solid understanding of SRE practices including SLIs, SLOs, error budgets, and proactive reliability.
• Strong troubleshooting, analytical, and performance optimization skills.
• Excellent communication and collaboration skills, with the ability to influence and guide technical stakeholders.

Nice to Have

• Experience with network programmability (Python, API-driven networking, NetConf/RESTConf).
• Exposure to cloud networking (AWS, Azure, GCP).
• Knowledge of zero-trust, SD-WAN, and network security best practices.
• Experience creating self-healing or fully automated network workflows.
