As an Infrastructure Engineering Manager at Unifonic, you will lead the engineering and operations of production cloud platforms, combining Infrastructure Engineering, Site Reliability Engineering (SRE), Cloud Platform Engineering, and AI-native engineering to ensure reliability, scalability, security, performance, and automation. You will remain hands-on by reviewing infrastructure code and architecture, troubleshooting complex production issues, working with Kubernetes and cloud services, and using AI engineering tools such as Claude Code daily. You will focus on Google Cloud Platform (GCP) and Oracle Cloud Infrastructure (OCI), with strong practical GCP expertise to support the ongoing migration to GCP, while collaborating with the Infrastructure Engineering Manager – Developer Experience, who is responsible for non-production environments, CI/CD, and developer tooling.

Help us shape the future of communication by:

• Owning the architecture, engineering, operation, and continuous improvement of production infrastructure across GCP and OCI.
• Taking a leading technical role in migrating production workloads to GCP.
• Designing highly available, scalable, resilient and secure production platforms.
• Setting engineering standards for compute, networking, storage, IAM and cloud-native services.
• Making sure the architecture meets availability, performance, capacity and disaster recovery requirements.
• Establishing consistent engineering patterns across GCP and OCI instead of treating each cloud as an isolated platform.
• Owning production Kubernetes platforms and their supporting ecosystem.
• Keeping clusters secure, observable, scalable, resilient and automated.
• Owning platform capabilities including ingress, service networking and service mesh, monitoring and logging.
• Working with application engineering teams to improve workload reliability and operational readiness.
• Building automation and self-service capabilities that reduce manual infrastructure work.
• Establishing and improving SRE practices across production infrastructure.
• Driving reliability through meaningful SLIs, SLOs, and operational metrics.
• Improving availability, capacity management and production resilience.
• Leading infrastructure-level troubleshooting during complex production incidents.
• Championing rigorous root-cause analysis and permanent corrective actions.
• Reducing operational toil through engineering and automation.
• Improving monitoring, observability, and early detection of infrastructure problems.
• Building reliability into architecture and design, not only after incidents.
• Driving an Infrastructure-as-Code-first operating model.
• Keeping strong discipline around Terraform, reusable modules, automated validation and controlled production changes.
• Making sure infrastructure changes follow software engineering practice: source control, pull requests, peer review, testing and automated deployment.
• Using Bitbucket as the core of the infrastructure engineering workflow.
• Holding infrastructure repositories to the same standards as production application code.
• Embedding AI into daily infrastructure engineering, not as an occasional add-on.
• Using Claude Code to understand repositories, develop and review infrastructure code, investigate problems and automate workflows.
• Building and using MCP (Model Context Protocol) servers that connect AI agents to infrastructure tooling.
• Applying AI to infrastructure monitoring, optimisation, incident investigation and root-cause analysis.
• Using AI to develop, validate and review Terraform.
• Defining where human validation and approval remain essential.
• Making sure AI is used safely around production systems, credentials and sensitive operational data.

Oversee critical production platform and backing services, including their lifecycle, standardisation, automation, availability, security, backup and disaster recovery:

• Databases and data infrastructure (for example MySQL, PostgreSQL)
• Caching (for example Redis)
• Messaging and middleware
• Kubernetes platform services
• Networking and connectivity
• IAM and secrets management
• Observability platforms
• Backup and recovery services
• Build security into infrastructure design and day-to-day engineering.
• Own IAM, network security, segmentation, secrets management and infrastructure hardening.
• Partner with Security Engineering on vulnerabilities and production risks.
• Make sure AI-assisted engineering follows security and governance controls.
• Keep infrastructure changes auditable through Infrastructure as Code and source control.
• Put guardrails and human oversight on production automation.
• Lead, mentor and grow a high-performing team of Infrastructure and SRE engineers.
• Stay technically credible: guide architecture, review solutions and join complex troubleshooting.
• Build a culture of engineering ownership rather than ticket handling.
• Challenge manual processes and find opportunities to automate.
• Drive adoption of AI-native engineering and coach engineers on Claude Code, MCP tooling and AI-assisted workflows.
• Partner with Product Engineering, Security and other teams on production platform strategy.
• Set clear engineering standards and keep documentation and knowledge sharing strong.
