Qualifications

• Experience in platform engineering, DevOps, infrastructure engineering, backend engineering, SRE, or developer tooling.
• Strong hands‑on experience with Kubernetes, Docker, CI/CD, and modern deployment workflows.
• Comfortable writing production‑quality automation or tooling in Go, Python, TypeScript, or JavaScript.
• Familiarity with infrastructure as code and GitOps workflows (Terraform, Argo CD, Helm, Kustomize).
• Experience with CI/CD systems such as GitHub Actions or similar tooling.
• Understanding of how applications are built, containerised, deployed, configured, monitored, and operated.
• Strong design fundamentals around reliability, scalability, observability, and maintainability.
• Product‑minded approach to platform engineering; building platform as a product.

Responsibilities

• Build and improve internal platform capabilities used by engineering teams and customers.
• Design and implement tooling, automation, workflows, and integrations to boost developer velocity.
• Collaborate with backend engineers to simplify building, testing, deployment, observation, and security of services.
• Create platform primitives for lifecycle management, provisioning, deployment automation, configuration, and secrets.
• Develop golden paths, reusable templates, and self‑service workflows for engineers.
• Work with Kubernetes, Docker, Terraform, Argo CD, GitOps, GitHub Actions, Helm, Kustomize, registries, and CNCF tooling.
• Write code and automation in Go, Python, TypeScript, or JavaScript.
• Improve CI/CD pipelines, release workflows, deployment safety, and environment management.
• Integrate platform tools into cohesive workflows rather than fragmented infrastructure pieces.
• Evaluate and operationalise CNCF tools to enhance the platform.
• Build systems that work across GCP, on‑premise, bare‑metal, sovereign cloud, air‑gapped environments.
• Contribute to observability, alerting, logging, tracing, dashboards, and production debugging workflows.
• Define platform standards, reusable templates, and operational patterns.
• Collaborate with infra engineers on platform vs core infrastructure boundaries.
• Take ownership of defined projects and grow into broader technical responsibility.
