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 SkillsCloud & 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 Levels0–5 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.
