Infrastructure Architect

- On-premises infrastructure
- Virtualisation
- Scalable compute environments
- Secure infrastructure design 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.

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 engine
