Job Description

The context:

Scyne runs a multi-cloud workplace that supports our consultants, our internal platforms and the AI capabilities we build for clients. Our business systems, including Dynamics 365, SharePoint and other SaaS applications, are connected through an integration platform built on Azure Integration Services. Day-to-day operations are delivered with a managed service provider (MSP). This role is the technical authority that makes the three clouds and the integration platform work as one secure, well-governed estate.

As the Lead Cloud Architect, you will own the design, build, security and ongoing health of Scyne's cloud platforms across Microsoft Azure, Amazon Web Services (AWS) and Google Cloud Platform (GCP), and of the integration platform that connects Scyne's business systems. This is a hands-on leadership role: you will set the architecture and guardrails, and you will also write the infrastructure code, review the changes and resolve the hard problems yourself.

You will define how workloads land in each cloud, how identity, networking, logging and security controls are applied consistently, and how changes move safely from design to production.



You will maintain and uplift the existing integration platform so it is secure, observable and ready for new integrations. You will direct the MSP's work, hold them to agreed standards and service levels, and make sure that what is built matches the architecture Scyne has approved.

In this role, you will:

- Own the end-to-end cloud architecture across Azure, AWS and GCP, including landing zones, account and subscription structure, identity, networking, logging and shared services.
- Design, deploy and maintain cloud infrastructure hands-on using infrastructure as code (such as Terraform or Bicep) and CI/CD pipelines in GitHub Actions or Azure DevOps.
- Define and enforce guardrails in each cloud, such as Azure Policy, AWS Service Control Policies and Control Tower, and GCP Organisation Policies, so that secure configuration is the default.
- Lead the security posture of the cloud estate, including identity and access management, privileged access, encryption and key management, network segmentation, and vulnerability and configuration management.
- Own Scyne's integration platform on Azure Integration Services (Logic Apps, API Management, Service Bus, Azure Functions and Event Grid), keeping existing integrations reliable, secure and well supported.
- Lead the uplift of the integration platform: define the target architecture, reusable integration patterns and API standards,



and deliver improvements to resilience, security, monitoring and deployment automation.
- Design and deliver new integrations between business systems such as Dynamics 365, SharePoint and other SaaS applications, applying secure authentication (managed identities, OAuth) and secrets management.
- Operate and tune cloud-native security tooling (such as Microsoft Defender for Cloud, AWS Security Hub and GuardDuty, and GCP Security Command Center) and work with the security team to act on findings.
- Orchestrate the MSP: set technical direction, review designs and change requests, approve or challenge implementation approaches, and track delivery against service levels.
- Prepare and present cloud changes at the Change Advisory Board, and ensure every change has a clear implementation, test and rollback plan.
- Align cloud controls with relevant frameworks and obligations, including the ASD Essential Eight, the Information Security Manual (ISM), ISO/IEC 27001 and CIS Benchmarks.
- Manage cloud cost and capacity, applying FinOps practices such as tagging standards, budgets, right-sizing and reserved capacity.
- Produce and maintain architecture decisions, standards, patterns and as-built documentation that others can rely on.
- Support the AI Engineering team with secure, scalable platforms for AI workloads, including model hosting, data services and workload identity.
- Lead cloud incident response and problem management with the MSP, and drive root-cause fixes.

- 10+ years' experience in infrastructure, cloud or platform engineering, including at least 5 years designin
