Job description

Location: Central London / Hybrid (2 Days On-Site)

Contract Model: Inside IR35

Duration: 12 Months (Phased Multi-Year Transformation)

The Mandate:

Are you an elite AWS Infrastructure Architect looking to design cutting-edge hybrid cloud environments for one of London’s largest, highly complex infrastructure estates?

We are deploying a global, zero-touch deployment factory to modernise high-availability, low-latency edge environments. We need a hands-on Cloud Infrastructure Architect specializing in AWS Outposts, hybrid routing, and automated site provisioning to own the reference architectures and IaC templates driving this rollout.

What You'll Be Building:

• Edge & Hybrid Architecture: Architecting multi-site AWS Outposts estates seamlessly integrated via Transit Gateway, Local Gateway routing, and custom ENI design.
• Zero-Touch IaC Factories: Designing standard and variable IaC site templates ("Terraform / AWS CDK") that turn complex infrastructure provisioning into repeatable pipeline runs.
• High-Performance Storage & Data Planes: Defining storage, replication, and data-plane architectures optimized for ultra-low-latency, mission-critical workloads.
• Operational Excellence: Authoring infrastructure standards, resilience frameworks, and disaster recovery architectures across distributed hardware estates.

What We're Looking For:

• AWS Edge Mastery: Hands-on experience with AWS Outposts ordering, installation, base configuration, and lifecycle management.
• Advanced Networking: Deep expertise across AWS VPC, Transit Gateway, Local Gateway routing, and ENI design.
• IaC Engine: Advanced proficiency in Terraform or AWS CDK for modular, immutable infrastructure provisioning.
• Certifications (Preferred): AWS Certified Solutions Architect - Professional or AWS Certified Advanced Networking - Specialty.
• Nice-to-Haves: Exposure to Telco 5G/CNF cloud architecture, Cilium/eBPF pod networking, or ultra-low-latency financial/trading infrastructure.

Why Apply?

This is not an advisory oversight role-It’s a high-impact, practitioner-led engagement delivering mission-critical infrastructure transformation alongside elite engineering teams.
