The Platform Engineer is responsible for designing, building, and maintaining the internal developer platform that enables software engineering teams across Sanlam Fintech to deliver value efficiently and reliably. This role focuses on creating self‑service infrastructure abstractions, standardised tooling, and automated workflows that reduce cognitive load on development teams while enforcing organisational best practices for security, compliance, and operational excellence.

You will work at the intersection of software development and infrastructure operations, applying software engineering principles to infrastructure challenges. Your primary customers are fellow engineers, and your success will be measured by developer productivity, platform adoption, and reduction in operational toil across multiple diverse teams.

• Design and implement self‑service developer portals and golden paths that enable development teams to provision infrastructure, deploy applications, and manage services independently
• Build and maintain internal developer portal capabilities that provide service catalogues, documentation, and operational dashboards
• Create intuitive abstractions that hide infrastructure complexity while maintaining flexibility for diverse team requirements

• Develop and maintain reusable Terraform modules and Cloud Formation templates that encode organisational standards for AWS resources

• Implement Git Ops workflows and automated deployment strategies including blue‑green and canary deployments
• Leverage AI tools (Claude, GPT) to accelerate development, improve automation quality, and enhance documentation

• Deploy, operate, and optimise Kubernetes clusters (EKS) and containerised workloads
• Develop Helm charts, Kubernetes operators, and standardised deployment manifests for platform consumers

• Implement comprehensive observability using Datadog including custom dashboards, alerts, and SLO tracking
• Define and monitor platform SLIs, SLOs, and error budgets to ensure reliability standards are met

• Work across multiple diverse teams to identify optimisation opportunities and drive adoption of platform capabilities
• Collaborate with development teams to understand their needs and build appropriate abstractions that improve their workflows
• Maintain comprehensive documentation in Confluence and manage work effectively using Jira and the Atlassian suite

• 5+ years of experience in software engineering, Dev Ops, platform engineering, or site reliability engineering
• Demonstrated experience building and operating production infrastructure at scale
• Track record of improving developer productivity and implementing self‑service capabilities
• Experience working across multiple teams to drive adoption of platform capabilities
• Relevant tertiary qualification in Computer Science,…
