Location- Ireland (Dublin)

Why Confluence?

At Confluence, we’ve always been driven by a commitment to innovation, precision, and partnership in the investment data space. Our global footprint now spans multiple countries, giving our employees the opportunity to get exposure to other countries and cultures. And it stands to reason that none of this would have been possible without the hundreds of hard-working employees who work at Confluence.

More about the role & team

This is a senior, hands-on networking opportunity where you’ll own enterprise infrastructure end-to-end — from initial design through implementation and into steady-state operations. Working closely with infrastructure and business stakeholders, you’ll deliver complex network solutions while ensuring they are scalable, secure, and fully embedded into ongoing support. This role exists to strengthen internal expertise and reduce reliance on external vendors, placing you at the center of critical infrastructure transformation initiatives.

You’ll operate as a true Subject Matter Expert and technical escalation point, leading troubleshooting, optimizing performance, and driving continuous improvement across the network estate. Beyond delivery, you’ll play a key role in enabling the wider team through knowledge transfer, documentation, and best practices. This role suits a senior network engineer who enjoys both building and owning solutions, and who thrives in environments where they can influence standards, drive change, and work across large-scale, multi-site infrastructure.

Own the full network lifecycle — from design through to operations, not just delivery
Step into a true SME role with visibility and influence across infrastructure decisions
Work hands-on with modern Cisco technologies, including SD-WAN transformation
Drive real impact by building internal capability and reducing vendor reliance
Gain exposure to enterprise-scale, multi-site environments and cross-functional initiatives

Based in a major tech hub (e.g., Toronto, US, or Ireland), this is an attractive opportunity for candidates looking to work on modern Cisco technologies and SD-WAN transformation within an enterprise-scale environment. You’ll gain exposure to cross-functional initiatives, cloud-integrated infrastructure, and projects with real business impact—ideal for those ready to step into a visible, high-impact engineering role with long-term growth

What skills and experience do I need to succeed?

8+ years’ experience in enterprise IT infrastructure or networking roles
Strong hands-on experience with Cisco technologies (Firepower, ISE, SD-WAN – Viptela/Catalyst)
Deep knowledge of network infrastructure (routing, switching, firewalls, VPNs, load balancing)
Expertise in routing protocols (BGP, OSPF, EIGRP) across multi-site environments
Proven experience designing, implementing, and transitioning solutions into production
Strong troubleshooting skills, including root cause analysis and incident resolution
Experience maintaining infrastructure health (patching, upgrades, configurations)

Experience in SaaS or cloud-based environments
Exposure to virtualized infrastructure (e.g., VMware)
Familiarity with enterprise storage platforms (e.g., NetApp)
Experience with scripting or automation (PowerShell, Python, Terraform, Ansible)
Cisco certifications (CCNP or CCIE)
