Job description

We are partnering with a well-established financial institutions to secure a Head of Infrastructure Architecture. This is a rare, high-leverage mandate that sits at the intersection of executive strategy and elite engineering.

We are not looking for an "ivory tower" governance profile. We need a formidable technical leader who can author the strategic blueprint for a massive multi-cloud evolution, while possessing the engineering grit to command a war room during complex, multi-layer production escalations. This executive role is critical to aligning technology investments with the institution's long-term strategic objectives.

What You'll Be Doing

• Command the Architecture: Dictate the multi-year architectural roadmap and reference blueprints across a sprawling on-prem estate and secure public cloud landing zones.
• Design for Autonomy: Architect resilient, automated patterns for network segmentation, storage fabrics, and hyper-converged compute using advanced Infrastructure-as-Code (IaC) paradigms.
• Elite Escalation: Serve as the apex technical authority. When a critical cross-layer incident hits production, you are the one diagnosing BGP route leaks, ARP flux, and hypervisor resource contention—turning those deep-dives into automated safeguards.
• Engineering Alignment: Act as the strategic bridge between fragmented operations, security, and application divisions, forging a unified, zero-trust engineering culture.

What We're Looking For

You bring over 15 years of combat-tested experience in enterprise infrastructure, with a track record of driving systems from whiteboard design into high-velocity live operations.

• Enterprise Networking: Deep mastery of Cisco/Arista/Juniper routing protocols (BGP/OSPF), edge security, F5 load balancing, and complex L2/L3 topologies.
• Compute & Virtualization: Unrivaled expertise in the VMware ecosystem. You understand the granular mechanics of NUMA boundaries, CPU scheduling, and memory pressure.
• Storage Fabrics: High-performance SAN/NAS/Object storage tiering, latency optimization, and multi-site replication for mission-critical RPO/RTO mandates.
• Public Cloud Vanguard: Proven experience designing and securing AWS/Azure/GCP landing zones, bridging legacy data centers with modern cloud architecture.

This is a defining career move for an architect who refuses to step away from the technology. You will wield massive scale, enjoy high executive visibility, and operate with absolute technical autonomy to shape the future of the technology landscape.
