What does this role do?

Platform Engineers build and operate Internal Developer Platforms (IDPs). They abstract the complexity of cloud and infrastructure so that product teams can focus on shipping features.

  • Design and maintain the internal developer platform (IDP)
  • Build golden path templates for application deployment
  • Operate the shared Kubernetes platform across all teams
  • Manage IaC foundations with Terraform and Bicep modules
  • Provide self-service CI/CD pipelines and platform tooling
  • Own platform reliability: SLOs, on-call, and incident management

Industry Context

Platform Engineering has emerged as a mature discipline from "DevOps teams" as organizations grow. It is driven by the recognition that every product team shouldn't rebuild infrastructure from scratch.

Platform Engineers typically own Kubernetes clusters, Terraform module registries, shared pipelines, and developer portals like Backstage.

  • High demand in companies with 50+ engineers
  • Often senior DevOps engineers who transitioned to platform focus
  • Progression: Platform Engineer → Staff Platform Engineer → Principal

Your 10-Step Roadmap

Master the complete platform engineering stack from containers and IaC through to observability and SRE practices.

01
🐧 LinuxFoundation

Systems-level Linux knowledge is required. Process management, namespaces, cgroups, networking, and storage — the foundations that containers are built on.

02
🐳 DockerContainers

Container runtime internals, image optimization, multi-stage builds, registry management, and container security — the base layer of the platform stack.

03
☸️ KubernetesCore Orchestration

Deep Kubernetes knowledge: custom resources, admission controllers, network policies, RBAC, storage classes, and cluster management for platform teams.

04
🏠 AKSManaged Kubernetes

Operate AKS clusters at platform scale: system and user node pools, cluster autoscaler, AAD integration, workload identity, private clusters, and upgrade strategies.

05
⎈ HelmApplication Packaging

Build and maintain the organization's Helm chart library. Chart versioning, library charts, chart testing, OCI registry publishing, and golden path chart templates.

06
🏗️ Terraform + BicepIaC Platform

Build the IaC module registry that all product teams consume. Terraform module versioning, Bicep templates, and automated IaC testing pipelines.

07
⚡ GitHub ActionsCI/CD Platform

Build reusable workflows, shared action libraries, and self-service pipeline templates that product teams call without managing pipeline code themselves.

08
📊 Prometheus + GrafanaObservability Platform

Build the shared observability platform: federated Prometheus, Thanos for long-term storage, Grafana with team-level dashboards, and alerting infrastructure.

09
🌐 Azure NetworkingPlatform Networking

Design the shared network foundation product teams build on: hub-spoke VNets, Private Endpoints, DNS zones, and network policies for multi-tenant Kubernetes clusters.

10
🛠️ SRE PracticesReliability

Apply SRE principles to the platform itself: define platform SLOs, error budgets, on-call runbooks, and reliability reviews for teams onboarding to the platform.

What You'll Actually Build

Internal Developer Platform

Build a self-service platform where any team can provision a new microservice environment (AKS namespace, CI pipeline, monitoring dashboards, secrets) in under 10 minutes via a portal form.

Shared Terraform Module Registry

Create a versioned Terraform module library covering AKS, networking, Key Vault, and monitoring. Teams consume modules as dependencies — infrastructure becomes standardized and auditable.

Multi-Tenant Kubernetes Platform

Operate an AKS cluster shared by 20 product teams with namespace isolation, RBAC, network policies, resource quotas, and per-team observability dashboards — all managed via GitOps.

Common Interview Questions

Fundamentals

What is an Internal Developer Platform (IDP) and how does it differ from DevOps tooling?
What is GitOps and how does it apply to platform engineering?
How do you isolate teams on a shared Kubernetes cluster?

Intermediate

How do you design a Terraform module that is reusable across 50 teams with different configurations?
How do you handle cross-team dependency management in a shared platform?
What is workload identity and why is it preferred over service principals on AKS?

Scenario-based

A product team says your platform is too slow to onboard. How do you measure and improve the experience?
Two teams are fighting over AKS node pool capacity. How do you design fair resource allocation?
A Terraform module change breaks 15 downstream services simultaneously. How do you prevent this in future?
