Platform Engineer

Definition

A Platform Engineer is a technical professional who designs, builds, and maintains software systems using programming languages and development frameworks. This specialized role requires deep technical expertise, continuous learning, and collaboration with cross-functional teams to deliver high-quality software products that meet business needs.

Platform Engineer is a fundamental concept in tech recruiting and talent acquisition. In the context of hiring developers and technical professionals, platform engineer plays a crucial role in connecting organizations with the right talent. Whether you're a recruiter, hiring manager, or candidate, understanding platform engineer helps navigate the complex landscape of modern tech hiring. This concept is particularly important for developer-focused recruiting where technical expertise and cultural fit must be carefully balanced.

What Google Cloud Developers Actually Do


GCP roles vary significantly by company needs:

Cloud/Platform Engineers

Build and manage infrastructure on GCP:

  • Compute Engine, GKE (Google Kubernetes Engine) management
  • Cloud Functions and Cloud Run (serverless)
  • Infrastructure as Code (Terraform, Deployment Manager)
  • Multi-region deployments and networking

Data Engineers

Leverage GCP's data strengths:

  • BigQuery for data warehousing and analytics
  • Dataflow for stream and batch processing
  • Pub/Sub for event-driven architectures
  • Cloud Storage for data lakes
  • ML pipelines with Vertex AI

ML Engineers

Build machine learning systems:

  • Vertex AI for model training and deployment
  • AutoML for no-code ML solutions
  • TensorFlow integration (Google's ML framework)
  • MLOps pipelines and model serving

Kubernetes Specialists

Manage containerized workloads:

  • GKE (Google Kubernetes Engine) expertise
  • Multi-cluster management
  • Istio service mesh integration
  • Container-native development

Skill Levels

Level 1: GCP User

Can deploy and manage basic resources:

  • Console navigation and basic services
  • Compute Engine VMs
  • Cloud Storage buckets
  • Basic IAM understanding

This is application developer level—fine for devs who deploy to GCP.

Level 2: GCP Practitioner

Can architect and manage production systems:

  • Infrastructure as Code (Terraform preferred)
  • GKE cluster management
  • Networking (VPC, Cloud Load Balancing)
  • IAM policies and service accounts
  • Cost optimization strategies

This is what most "GCP experience" job requirements mean.

Level 3: GCP Expert

Can design and optimize complex systems:

  • Multi-region architecture
  • Advanced BigQuery optimization
  • ML pipeline design
  • Security hardening and compliance
  • Cost optimization at scale

This is senior Cloud/Data Engineer territory.


GCP's Unique Strengths

1. BigQuery: The Data Warehouse Leader

BigQuery is GCP's standout service:

  • Serverless, petabyte-scale analytics
  • SQL interface with ML functions
  • Real-time streaming inserts
  • Integration with Google Analytics, Ads

Look for: Candidates who've optimized BigQuery queries, designed data pipelines, or built analytics dashboards.

2. Kubernetes: Born at Google

GKE (Google Kubernetes Engine) benefits from Google's Kubernetes expertise:

  • Managed Kubernetes with advanced features
  • Multi-cluster management
  • Integrated with Google's networking
  • Strong security defaults

Look for: Kubernetes experience often translates well to GCP, especially GKE.

3. Machine Learning Integration

GCP excels at ML workflows:

  • Vertex AI unified ML platform
  • AutoML for non-ML engineers
  • TensorFlow integration
  • MLOps tooling

Look for: ML engineers often prefer GCP for its ML-first approach.

4. Global Network Infrastructure

Google's private fiber network:

  • Low-latency global connectivity
  • Premium network tier
  • Edge locations worldwide

Look for: Candidates who understand network architecture and latency optimization.


Interview Focus Areas

Must Assess

  1. BigQuery/data experience - If you're data-heavy, this is critical
  2. Kubernetes/GKE knowledge - Especially if containerizing
  3. ML pipeline experience - If building ML products
  4. Cost awareness - GCP can be expensive without optimization

Common Mistakes

  • Testing AWS knowledge and expecting GCP expertise
  • Over-emphasizing certifications without production experience
  • Not understanding GCP's data/ML strengths
  • Assuming AWS experience directly translates (it mostly does, but differences matter)

GCP vs AWS: Key Differences

When GCP Makes Sense

  • Data-heavy workloads: BigQuery is superior to Redshift
  • ML/AI focus: Vertex AI and TensorFlow integration
  • Kubernetes-first: GKE is more mature than EKS
  • Google ecosystem: Already using Google Workspace, Analytics

When AWS Might Be Better

  • Larger ecosystem: More services and third-party integrations
  • Enterprise support: More enterprise-focused features
  • Market share: Easier to find AWS talent
  • Cost: AWS often cheaper for basic compute

For hiring: GCP developers often have deeper data/ML backgrounds. AWS developers can learn GCP quickly, but BigQuery and ML services have learning curves.


Recruiter's Cheat Sheet

Questions That Reveal Skill Level

Question Junior Answer Senior Answer
"How would you optimize a slow BigQuery query?" "Add more slots" "Check query plan, optimize JOINs, consider partitioning/clustering, review data types"
"What's the difference between Cloud Functions and Cloud Run?" "Both are serverless" "Cloud Functions is event-driven, Cloud Run is container-based with more control"
"How do you manage GKE clusters at scale?" "Use the console" "Terraform for IaC, GitOps with ArgoCD, multi-cluster management, monitoring"

Resume Green Flags

  • Specific GCP services mentioned (BigQuery, GKE, Vertex AI)
  • Data engineering or ML background
  • Production scale experience ("Managed 50TB BigQuery datasets")
  • Cost optimization achievements ("Reduced GCP costs by 40%")
  • Kubernetes experience (especially GKE)

Resume Red Flags

  • Only lists "cloud experience" without specifics
  • Claims GCP expertise but only used Compute Engine
  • No mention of BigQuery or data services (if hiring for data roles)
  • Never worked with Infrastructure as Code

Common Hiring Mistakes

1. Assuming AWS Experience = GCP Experience

While concepts transfer, GCP has unique services:

  • BigQuery is very different from Redshift
  • GKE has different defaults than EKS
  • IAM model differs from AWS

Better approach: Test for GCP-specific knowledge if that's what you use.

2. Ignoring GCP's Data/ML Strengths

If you're hiring for data or ML roles, GCP's strengths matter:

  • BigQuery expertise is valuable
  • Vertex AI knowledge is rare
  • Dataflow experience indicates strong data engineering

Better approach: Prioritize candidates with relevant GCP service experience.

3. Over-Emphasizing Certifications

GCP certifications (Professional Cloud Architect, Data Engineer) indicate knowledge but don't guarantee production skills.

Better approach: Ask about real projects: "Tell me about a BigQuery optimization you did" or "How did you design a GKE cluster?"

4. Not Understanding Cost Structure

GCP pricing differs from AWS:

  • Sustained use discounts vs Reserved Instances
  • Network egress costs can surprise
  • BigQuery pricing based on data scanned

Better approach: Ask candidates about cost optimization strategies specific to GCP.

Frequently Asked Questions

Frequently Asked Questions

GCP has a smaller talent pool but stronger in data/ML. AWS developers can learn GCP quickly for general cloud work, but BigQuery and Vertex AI require specific experience. If you're data/ML-heavy, prioritize GCP experience. For general cloud infrastructure, AWS experience often transfers well.
