About the Role:


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

This is a hands-on leadership role in a lean organisation where you'll shape cloud architecture, modernise a legacy platform into a cloud-native environment, and provide senior oversight across platform engineering, security, SRE, CI/CD.


Key Responsibilities:

  • Own the AWS platform architecture and modernisation roadmap, including migration from a Java monolith to microservices on EKS.

  • Define standards for containers, runtime environments, observability, tenancy, security, and infrastructure automation.

  • Lead SRE practices including SLI/SLOs, incident management, DR/BCP planning, post-mortems, and operational resilience.

  • 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.

  • 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.
