We're partnering with a growing SaaS business to hire a senior Platform Architect to own the design, security, reliability, and operational management of their AWS platform and internal IT function.

* Own platform security, secure SDLC, CI/CD pipelines, IaC, and software supply chain governance.
* Drive developer productivity through automation, self-service tooling, and platform standardisation.
* Provide senior oversight of IT operations including service desk governance, endpoint management, onboarding/offboarding, patching, ITAM, and MSP/vendor management.
* Act as a senior escalation point for critical incidents, outages, and operational issues.
About You:
* Experience within a platform, infrastructure, or software engineering within SaaS environments.
* Strong AWS expertise including EKS, IAM, networking, KMS, RDS, and multi-account architecture.
* Hands-on Kubernetes, CI/CD, Terraform, and cloud security experience.
* Strong understanding of SRE, observability, incident response, and disaster recovery.
* Experience operating within regulated environments such as ISO 27001, SOC 2, or GxP.
* Comfortable balancing strategic leadership with hands-on operational delivery.
* AWS Solutions Architect - Professional certification required.
* CKA or CKS certification highly desirable.
