How to Become a Platform Engineer

Platform Engineers build and maintain internal developer platforms (IDPs) that enable software development teams to deploy, run, and manage applications efficiently. They create self-service infrastructure tools, automate workflows, and abstract away complexity so developers can focus on building features rather than managing infrastructure.

What makes this role unique: Platform Engineers treat their platform as a product—designing it for internal developer customers. Unlike DevOps engineers who may work directly with development teams on deployments, platform engineers create abstracted, self-service tooling that enables developer autonomy at scale.

Best suited for: Engineers who enjoy building tools that make other developers more productive. Best suited for those who think in systems, enjoy automation, and want to have multiplied impact—improving the productivity of entire engineering organizations rather than shipping individual features.

With 451,360 professionals employed nationwide and 3% projected growth, this is a strong career choice. Explore Computer Science degree programs to get started.

'Too many tools' is the core of what makes platform engineering difficult. It's not just individual tools—it's cloud providers, internal components, dependencies, scripts your team wrote, and everything else that makes up this highly interconnected infrastructure you're supposed to simplify for others. Continuous learning is essential as the landscape evolves constantly.

Morning: Review monitoring dashboards and alerts for platform services. Triage any overnight incidents. Check pipeline failures and help development teams unblock. Review and merge infrastructure-as-code PRs.

Afternoon: Work on platform improvements—building new automation, improving developer tooling, or designing new platform capabilities. Meet with development teams to understand their needs and gather feedback on platform features.

Core daily tasks include:

• Building and maintaining CI/CD pipelines
• Managing Kubernetes clusters and containerized workloads
• Writing Infrastructure as Code (Terraform, Pulumi)
• Creating developer self-service tools and portals
• Implementing observability and monitoring solutions
• Automating operational tasks and toil reduction

Essential Tools: Platform Engineers rely heavily on these core technologies:

• Kubernetes: Container orchestration platform—the foundation of most modern platform engineering. Deep expertise in cluster management, operators, and service mesh required.
• Terraform: Leading IaC tool (71% of platform engineers use it). Modular, cloud-agnostic infrastructure management. Essential for declarative infrastructure.
• Prometheus/Grafana: Monitoring and observability stack. Prometheus used by 54.59% of platform teams. Real-time metrics collection and visualization.
• ArgoCD/Flux: GitOps deployment tools for Kubernetes. Enable declarative, git-driven deployments and configuration management.
• Docker: Container runtime and image building. Understanding containerization fundamentals is essential for platform work.

Also commonly used:

• GitHub Actions/Jenkins: CI/CD platforms for automating build, test, and deployment pipelines.
• HashiCorp Vault: Secrets management—securely managing API keys, credentials, and sensitive configuration.
• Crossplane: Kubernetes-native IaC enabling teams to define cloud resources using CRDs. Growing in platform engineering (13% adoption).
• Python/Go/Bash: Programming languages for automation scripts, tooling, and custom operators. Go particularly popular for Kubernetes tooling.
• DataDog/ELK: Observability platforms for log aggregation, APM, and system monitoring.

Emerging technologies to watch:

• OpenTofu: Open-source Terraform alternative (7% adoption), providing similar functionality without vendor lock-in concerns.
• Backstage: Spotify's open-source developer portal for building internal developer platforms with service catalogs and documentation.
• Spacelift: Platform-as-a-service for IaC—sophisticated CI/CD for Terraform, Pulumi, Kubernetes, and Ansible.

Start with AWS certification for your cloud platform, followed by CKA for Kubernetes. 'Certs are for HR. Your GitHub/projects are for the hiring manager.' The certification gets you the interview; practical problem-solving gets you the job. The knowledge gained studying for CKA is often more valuable than the certificate itself.

Beginner certifications:

• AWS Solutions Architect Associate (Amazon): $150, 2-4 months prep - Foundational cloud certification. AWS experience is highly valuable—many companies seek engineers with AWS core services expertise.
• KCNA (Kubernetes and Cloud Native Associate) (CNCF/Linux Foundation): $250, 1-2 months prep - Entry-level Kubernetes certification. Good starting point before pursuing CKA.

Intermediate/Advanced certifications:

• CKA (Certified Kubernetes Administrator) (CNCF/Linux Foundation): $445, 2-4 months prep - The most sought-after Kubernetes certification. 100% performance-based exam in live command-line environment. Huge resume booster for platform roles. Over 3,000 jobs explicitly require it.
• Terraform Associate (HashiCorp): $70.50, 1-2 months prep - Validates Terraform fundamentals. Useful for IaC-focused platform roles.

Must-have portfolio projects:

• See detailed requirements in the sections above

Projects to avoid: Simple tutorial follows without modifications, Projects without proper documentation or architectural explanation, Single-tool demos that don't show integrated platform thinking, Outdated technology stacks - these are too common and won't differentiate you.

GitHub best practices: Build a mini 'platform' in a cloud environment with IaC, CI/CD, and monitoring; Include README files explaining architectural decisions; Show GitOps workflows and infrastructure versioning

Platform engineering interviews typically include 1-2 system design rounds focused on infrastructure, hands-on technical assessments (often involving Kubernetes or IaC), and behavioral interviews. Over 70% of senior candidates at major tech companies face system design rounds. Be prepared to demonstrate practical skills, not just theoretical knowledge.

Common technical questions:

• "How would you design a scalable and fault-tolerant platform?" - Testing system design skills. Cover multi-AZ deployment, auto-scaling, load balancing, and isolation strategies for multi-tenant platforms.
• "Describe how you would architect a Kubernetes platform with security and scalability in mind." - Evaluating Kubernetes depth. Discuss cluster layout, RBAC, network policies, and maintainability as the team grows.
• "How would you migrate on-premise infrastructure to the cloud?" - Testing migration experience. Cover assessment, planning, phased approach, and risk mitigation strategies.
• "How do you approach reducing toil and improving developer productivity?" - Evaluating platform mindset. Discuss automation opportunities, self-service tooling, and measuring developer experience.
• "Describe your experience with CI/CD pipelines and GitOps." - Assessing practical experience. Discuss pipeline design, GitOps principles, and tools like ArgoCD or Flux.

Behavioral questions to prepare for:

• "Tell me about a time you had to balance platform improvements with urgent production issues." - Testing prioritization and on-call experience. Platform engineers must balance proactive work with reactive support.
• "Describe a situation where you had to advocate for a technical decision against resistance." - Platform engineers often face resistance to change. Show you can influence without authority.
• "How do you gather and incorporate feedback from developer users?" - Testing product mindset. Platform success depends on treating developers as customers.

Take-home assignments may include: Set up a Kubernetes cluster with CI/CD and monitoring using IaC; Design a multi-tenant platform architecture with security isolation; Build a self-service developer tool or automation workflow

Common challenges platform engineers face:

• Tool complexity and sprawl—managing highly interconnected infrastructure across multiple tools
• Small teams supporting large organizations—often 5-10% of engineering headcount
• Build vs buy dilemma—vendor tools may not fit organizational workflows
• Continuous learning burden—landscape evolves constantly

Common misconceptions about this role:

• That it's just DevOps with a new name—platform engineering has a distinct product-oriented mindset
• That you can just hire a team and expect immediate results—there's often an initial productivity dip
• That engineering is the biggest challenge—product management and organizational skills matter equally
