Platform Engineering

With expertise in Platform Engineering, you become the person building the foundation that other engineers build on. Internal tools, developer platforms, deployment systems—you create the infrastructure and abstractions that make your entire engineering team 10x more productive.

What You'll Actually Be Doing

As the Platform Engineering go-to person, your Thursday might look like building an internal API that abstracts away AWS complexities for product teams, then creating developer documentation because people keep asking how to deploy services, followed by optimizing the internal platform that handles 500 deployments per day.
  • Build internal platforms and tools for engineering teams
  • Create abstractions that simplify infrastructure complexity
  • Develop developer portals and self-service tools
  • Implement CI/CD systems and deployment automation
  • Design platform APIs that other teams build on
  • Monitor platform usage and optimize for developer experience

Core Skill Groups

Building Platform Engineering competency requires Kubernetes mastery, Docker expertise, and strong programming skills (Java/Python) for infrastructure platforms

Container Orchestration

ESSENTIAL
Kubernetes, K8s, OpenShift, EKS, AKS, GKE
Kubernetes appears in ~70% of Platform Engineer postings overall and ~70% at entry level. OpenShift appears in ~5%. Cloud-managed Kubernetes (EKS, AKS, GKE) add incremental coverage. Kubernetes completely dominates platform engineering—this is THE defining skill. Entry-level percentage identical to overall shows immediate expectation.

Containerization

ESSENTIAL
Docker, Container technologies
Docker appears in ~55-60% of Platform Engineer postings across all levels and entry level. Docker is the container runtime foundation beneath Kubernetes. Combined with Kubernetes, containerization expertise approaches 80%+ of postings. Essential baseline for platform work.

Programming & Automation

FOUNDATION
Java, Python, Go, C++, Bash
Java appears in ~20% of Platform Engineer postings overall but drops to ~20% at entry level. Python appears in ~15% overall and ~25% at entry level, showing strong growth for junior roles. Go appears in ~5%. C++ appears in ~5%. Programming proficiency is foundational for building platform tooling and automation. Python growing especially at entry level.

Infrastructure as Code

ESSENTIAL
Terraform, Ansible, Helm, CloudFormation
Terraform appears in ~20% of Platform Engineer postings overall and ~20% at entry level. Ansible appears in ~5-10%. Helm appears in ~5%. Combined IaC tool mentions reach ~25-30%. IaC is essential for platform engineering—managing infrastructure and Kubernetes deployments declaratively.

CI/CD & GitOps

COMPLEMENTARY
Jenkins, GitHub Actions, GitLab CI, ArgoCD, GitOps
Jenkins appears in ~5-10% of Platform Engineer postings. GitHub Actions appears in ~5%. ArgoCD appears in <5%. GitOps practices appear in <5%. CI/CD tools complement platform work for automated deployment and GitOps workflows. Lower than pure DevOps roles but still valuable.

Version Control

FOUNDATION
Git, GitHub, GitLab, Bitbucket
Git appears in ~10% of Platform Engineer postings overall and ~15-20% at entry level. GitHub, GitLab, Bitbucket add coverage. Higher entry-level emphasis shows Git as baseline expectation. Essential for managing platform code and configurations.

Cloud Platforms

COMPLEMENTARY
AWS, GCP, Azure, Cloud infrastructure
AWS appears in ~15% of Platform Engineer postings. GCP appears in ~5-10%. Cloud platforms complement platform engineering as Kubernetes often runs on cloud infrastructure. Important but secondary to core Kubernetes expertise.

Service Mesh & Networking

ADVANCED
Istio, Service mesh, API Gateway, Load balancers
Istio appears in <5% of Platform Engineer postings. Service mesh and advanced networking represent advanced platform capabilities—traffic management, observability, and security for microservices. Typically senior-level depth rather than entry-level.

Monitoring & Observability

COMPLEMENTARY
Prometheus, Grafana, Monitoring tools
Prometheus appears in ~5% of Platform Engineer postings. Grafana appears in <5%. Monitoring tools complement platform work for infrastructure observability. Valuable for ensuring platform health and reliability.

Databases & Data Persistence

COMPLEMENTARY
PostgreSQL, MySQL, MongoDB, Redis
Databases appear in <5% of Platform Engineer postings individually. Database knowledge complements platform work for stateful applications and data persistence in containerized environments. Helpful but not core focus.

Skills Insights

1. Platform = Kubernetes

  • K8s in ~70% of platform roles
  • Docker ~60%
  • Container orchestration IS platform
Platform without K8s like web without HTML.

2. Terraform Learned Later

  • Terraform <10% entry
  • IaC not expected upfront
  • Ansible similar pattern
K8s first. IaC month 2.

3. Python Over Java

  • Python stronger at entry
  • Go valued but not required
  • Scripting over application dev
Platform engineers automate. Python wins.

4. AWS Leads, Others Matter

  • AWS dominant presence
  • GCP better entry ratio
  • Multi-cloud future, single present
One cloud deep. Others broad.

Platform engineering is the evolution of DevOps - focus on abstractions and developer productivity
💎

Hidden Value & Differentiation

Undervalued skills that set you apart:

  • API design for internal platforms
  • Developer documentation and onboarding
  • Platform metrics and adoption tracking
  • Cost showback and resource optimization
  • Security and compliance automation
Treat internal developers as customers - platform success depends on adoption and satisfaction

What Separates Good from Great Engineers

Technical differentiators:

  • Building internal platforms that feel like products (great UX for internal users)
  • Abstraction layer design that hides complexity without limiting power users
  • Understanding infrastructure patterns that benefit multiple teams
  • Creating self-service capabilities that reduce ticket queues

Career differentiators:

  • Treating internal customers like external customers (support, docs, feedback)
  • Building platforms that teams actually want to use (not mandated)
  • Measuring platform value through team productivity metrics
  • Creating migration paths when platform needs to evolve
Your value isn't in building infrastructure—it's in creating platforms that multiply engineering productivity across teams. Great platform engineers obsess over developer experience and measure success by how many teams they enable.
