Network Reliability Engineer

We are seeking a Network Reliability Engineer (NRE) with hands-on experience across hybrid and cloud network environments, including on‑premises data centres and AWS/Azure cloud platforms. The role focuses on reliability, availability, scalability, automation, and observability of network and security platforms using NRE/SRE principles, CI/CD practices, and deep API‑driven integrations. Candidates should have experience in network domain automation using the Ansible Automation Platform.

Key Responsibilities

• Own end‑to‑end reliability and performance of hybrid and cloud‑connected network services.

• Apply Network Reliability Engineering (NRE) principles to reduce operational toil and improve service resilience.

• Design, implement, and continuously improve highly available hybrid and cloud network architectures.

• Perform deep technical troubleshooting and root cause analysis for complex network and security incidents.

• Build automation and self‑healing workflows supporting Day‑1, Day‑2, and Day‑N operations.

• Integrate infrastructure changes into CI/CD pipelines with proper testing, validation, and rollback.

• Define, monitor, and improve SLIs, SLOs, and error budgets for network services.

• Partner with cloud, security, application, and platform teams to meet business KPIs and KRAs.

Ansible

• Develop, maintain, and optimise Ansible playbooks, roles, and inventories to automate network device configuration, deployment, and operational activities across multi‑vendor environments.

• Automate routine network tasks such as configuration management, backups, compliance checks, firmware upgrades, and provisioning to reduce manual effort and improve reliability.

• Translate network SOPs, runbooks, and BAU activities into reusable Ansible‑based automation workflows (Infrastructure‑as‑Code) for scalable and consistent execution.

• Implement event‑driven and self‑healing automation by integrating Ansible playbooks with monitoring systems, APIs, and ITSM tools to enable automated remediation and faster incident resolution.

• Ensure network consistency and compliance by using Ansible to validate device state, detect configuration drift, and enforce standardised configurations across network infrastructure.

Hybrid, Cloud & Data Centre Networking

• Hands‑on experience supporting Cisco ACI fabrics integrated with hybrid connectivity models.

• Strong working knowledge of Cisco IOS‑XE and Cisco NX‑OS in enterprise and data centre environments.

• Experience managing Cisco Wireless LAN Controllers (WLC).

• Practical experience with AWS networking, including VPC design, routing, security groups, NACLs, Transit Gateway, VPN, and Direct Connect.

• Practical experience with Azure networking, including VNets, UDRs, NSGs, VPN Gateway, ExpressRoute, and Azure Firewall.

• Understanding of hybrid connectivity patterns such as internet, MPLS, site‑to‑site VPN, client VPN, and secure cloud access.

Network Security & Proxy Platforms

• Hands‑on experience with enterprise firewalls: Check Point, Palo Alto, and Cisco Firepower (FTD).

• Experience using AlgoSec for firewall policy lifecycle management and automation across hybrid and cloud environments.

• Strong expertise with proxy and secure web gateway solutions, including Bluecoat ProxySG (SGOS), BMC, and CAS.

• Cloud‑delivered security experience with Zscaler ZIA, ZPA, and ZTNA supporting hybrid and remote access models.

Application Delivery & Traffic Management

• Hands‑on experience with F5 VELOS chassis.

• Strong expertise in F5 LTM, GTM, and APM modules.

• Experience designing resilient application delivery for on‑prem and cloud workloads.

Monitoring, Observability & Telemetry

• Hands‑on experience with Datadog for monitoring hybrid and cloud network services.

• Experience with Cisco DNA Center (DNAC) for assurance and network automation.

• Experience with Forescout for network visibility, device profiling, and compliance.

• Strong experience building dashboards and alerts using Prometheus and Grafana.

Automation, CI/CD & Engineering Skills

• Strong experience with Ansible for network and security automation.

• Hands‑on experience integrating GitHub for version control, peer reviews, and change traceability.

• Experience building CI/CD pipelines for infrastructure and network changes.

• Experience using REST APIs, SDKs, CLI tools, and GUIs to integrate network, security, and cloud platforms.

• Experience developing tools, services, or dashboards using Python and Django.

• Ability to implement Infrastructure as Code (IaC) and automated validation workflows.

Skills & Competencies

• Strong reliability engineering mindset with focus on automation and scalability.

• Proven experience operating production hybrid and cloud network environments.

• Excellent troubleshooting and analytical abilities.

• Ability to translate business KRAs into measurable technical reliability objectives.

• Strong documentation, collaboration, and communication skills.

Qualifications

• Relevant experience in Network Engineering, Network Security, Cloud Networking, or NRE/SRE roles.

• Relevant certifications (e.g., CCNP/CCIE, AWS/Azure Networking, PCNSE, CCSA/CCSE, F5) are a plus.
