Infrastructure Architect - Cloud, DevOps & AI/ML

We are looking for Infrastructure Architects and experienced Cloud Infrastructure professionals to design and support secure, resilient, scalable, high-performance, and cost-effective infrastructure across cloud, on-premises, and hybrid environments. The role focuses on designing the infrastructure foundation for modern enterprise solutions, with particular emphasis on cloud platforms, compute, storage, networking, containerisation, Infrastructure-as-Code, high availability, disaster recovery, and data-intensive/AI/ML workloads. Candidates with different levels of experience are encouraged to apply, from strong infrastructure/cloud engineers looking to move into architecture through to experienced Infrastructure Architects. Requirements Key Responsibilities - Design end-to-end infrastructure architectures across cloud, on-premises, and hybrid environments - Define architecture across compute, storage, networking, databases, and platform services based on business and technical requirements - Design infrastructure requirements for data-intensive and AI/ML workloads, including GPU compute, high-throughput storage, scalable processing, and inference environments - Establish and maintain standards for Infrastructure-as-Code (IaC), environment management, automation, and configuration consistency - Design highly available infrastructure architectures with appropriate backup, disaster recovery, business continuity, RTO and RPO requirements - Ensure infrastructure designs meet security, compliance, data residency, and regulatory requirements - Perform capacity planning and cost optimisation, including resource right-sizing based on workload requirements - Review infrastructure architecture and technical changes and provide guidance to infrastructure, cloud, DevSecOps, and engineering teams - Support implementation teams by providing architecture guidance, technical standards, and recommended design patterns - Evaluate emerging cloud and infrastructure technologies and provide recommendations for adoption where appropriate - Contribute to infrastructure modernization, cloud migration, scalability, resilience, and performance improvement initiatives Core Technical Skills Cloud & Hybrid Infrastructure Experience with one or more major cloud platforms: - AWS - Microsoft Azure - Google Cloud Platform (GCP) - Hybrid cloud environments - On-premises infrastructure Candidates with strong expertise in one cloud platform are welcome, while multi-cloud experience will be an advantage. Compute, Networking & Storage Strong understanding of infrastructure architecture across: - Compute - Networking - Storage - Virtualisation - Load balancing - High availability - Disaster recovery - Backup and recovery - Business continuity - Performance and capacity planning Containers & Platform Technologies Experience with: - Docker - Kubernetes - Container orchestration - Container-based infrastructure - Cloud-native platform architectures Infrastructure-as-Code & Automation Experience with Infrastructure-as-Code and configuration management tools such as: - Terraform - AWS CloudFormation - Azure Bicep - Ansible - Other infrastructure automation tools Strong understanding of environment management, configuration consistency, automation, and repeatable infrastructure deployment is required. AI/ML & Data Infrastructure Experience designing infrastructure for data-intensive and AI/ML workloads is highly desirable. Relevant experience may include: - GPU compute infrastructure - High-throughput storage - Scalable compute environments - AI/ML infrastructure - Model training infrastructure - Model inference environments - Data processing workloads - Performance and capacity optimisation for AI/ML workloads Security & Compliance Strong understanding of: - Infrastructure security - Security architecture - Identity and Access Management (IAM) - Authentication and authorization - Network security - Cloud security - Data protection - Compliance requirements - Data residency - Secure infrastructure design The successful candidate should be able to incorporate security and compliance requirements into infrastructure architecture rather than treating them as an afterthought. High Availability & Disaster Recovery Experience designing resilient infrastructure with consideration for: - High Availability (HA) - Disaster Recovery (DR) - Backup strategies - Business Continuity - RTO - Recovery Time Objective - RPO - Recovery Point Objective - Failure recovery - Resilience and redundancy Architecture & Leadership Responsibilities For senior-level candidates, responsibilities may include: - Reviewing and approving infrastructure designs - Establishing infrastructure architecture standards and reference patterns - Providing technical direction to infrastructure and DevSecOps engineers - Leading architecture discussions and design reviews - Conducting technology evaluations and making adoption recommendations - Mentoring engineers and supporting technical capability development - Driving infrastructure modernization and optimization initiatives Required Qualifications Depending on seniority, candidates should demonstrate relevant experience across: - Cloud infrastructure architecture or engineering - AWS, Azure and/or GCP - Networking and virtualisation - Docker and Kubernetes - Infrastructure-as-Code - Infrastructure automation - Security and IAM - High availability and disaster recovery - Infrastructure performance and capacity planning For senior/architect-level positions: proven experience designing and governing enterprise-scale infrastructure architectures is expected. For junior/mid-level candidates: strong hands-on infrastructure/cloud engineering experience with the ability and ambition to progress into architecture will also be considered. Certifications - Desirable Relevant certifications are advantageous, including: - AWS Solutions Architect - AWS Certified Advanced Networking / Security - Microsoft Azure Solutions Architect - Google Cloud Architect - Kubernetes certifications - HashiCorp Terraform certifications - TOGAF - Other relevant cloud, infrastructure, security, or architecture certifications Preferred Experience Experience in one or more of the following environments will be an advantage: - Enterprise infrastructure - Cloud transformation - Hybrid cloud - Cloud migration - AI/ML platforms - Data platforms - DevSecOps - Financial services / banking - Highly regulated environments - Large-scale distributed systems What We're Looking For We are looking for people who can design, not just operate infrastructure — professionals who understand how compute, networking, storage, cloud, security, automation, resilience, and cost come together to support business-critical workloads. Candidates should demonstrate strong problem-solving skills, technical curiosity, ownership, and the ability to work collaboratively with architecture, engineering, security, data, AI/ML, and DevSecOps teams. Experience Levels 0-5 Years: Cloud/Infrastructure Engineers with strong hands-on exposure and a clear interest in architecture. 5-10 Years: Senior Cloud/Infrastructure Engineers with architecture and design experience. 10-15 Years: Infrastructure/Cloud Architects with enterprise-scale design and governance experience. 15+ Years: Lead/Principal Infrastructure Architects capable of owning complex enterprise and hybrid-cloud architecture strategies.
