Backend Developer

Definition

A Backend Developer 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.

Backend Developer is a fundamental concept in tech recruiting and talent acquisition. In the context of hiring developers and technical professionals, backend developer plays a crucial role in connecting organizations with the right talent. Whether you're a recruiter, hiring manager, or candidate, understanding backend developer 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.

AWS Developer Archetypes

"AWS developer" is broad. Clarify which role you need:

1. Cloud/Platform Engineer

Focus: Infrastructure as code, CI/CD, developer productivity
Primary Services: EC2, ECS/EKS, Lambda, CloudFormation, CDK
Daily Work: Terraform modules, deployment pipelines, developer tooling

2. DevOps/SRE Engineer

Focus: Reliability, monitoring, incident response
Primary Services: CloudWatch, X-Ray, Auto Scaling, Route 53
Daily Work: SLA management, on-call rotation, performance optimization

3. Data Engineer

Focus: Data pipelines, warehousing, analytics
Primary Services: S3, Redshift, Glue, Athena, Kinesis
Daily Work: ETL development, data modeling, cost optimization

4. Solutions Architect

Focus: System design, cross-team technical leadership
Primary Services: All of them—breadth over depth
Daily Work: Architecture reviews, vendor evaluation, technical roadmaps

5. Backend Developer with AWS

Focus: Application development on AWS services
Primary Services: Lambda, API Gateway, DynamoDB, SQS
Daily Work: Feature development, serverless functions, API design


Core AWS Competencies

Must Understand for Any AWS Role

1. Identity and Access Management (IAM)
Security foundation. They should explain:

  • Least privilege principles
  • Role-based access vs. user-based
  • Cross-account access patterns
  • When to use service accounts

2. Networking (VPC)

  • Public vs. private subnets
  • Security groups vs. NACLs
  • VPC peering and Transit Gateway
  • Why this matters for security and cost

3. Compute Options Trade-offs

  • EC2: Full control, predictable workloads
  • ECS/EKS: Container orchestration
  • Lambda: Event-driven, auto-scaling, cold starts
  • Fargate: Serverless containers

4. Cost Awareness
AWS bills can explode without attention. Good candidates discuss:

  • Reserved Instances vs. Spot vs. On-Demand
  • Right-sizing resources
  • Cost monitoring and alerts
  • Architecture decisions that affect cost

Certification vs. Experience

The Certification Reality

AWS certifications signal:
✅ Baseline knowledge of services
✅ Ability to pass structured exams
✅ Investment in learning

Certifications don't guarantee:
❌ Production architecture experience
❌ Debugging skills under pressure
❌ Cost optimization intuition
❌ Security best practices in practice

How to Evaluate

Ask about real projects:

  • "Tell me about an architecture you designed from scratch"
  • "Walk me through a production incident you resolved"
  • "How did you reduce AWS costs at your last company?"

Red flags:

  • Can only speak in certification terminology
  • No experience with Infrastructure as Code
  • Never worked on high-availability systems

Interview Questions That Reveal Skill

Architecture Understanding

Q: "How would you design a system that needs 99.9% uptime across multiple regions?"

Good answer includes:

  • Multi-AZ and multi-region deployment
  • Route 53 health checks and failover
  • Database replication (RDS Multi-AZ, Aurora Global)
  • Cost implications of redundancy

Red flag: Only mentions putting everything in "us-east-1"

Security Awareness

Q: "An application needs to access DynamoDB. How do you grant access?"

Good answer:

  • IAM role attached to the compute resource
  • Least privilege policy
  • No hardcoded credentials
  • Discusses cross-account scenarios if relevant

Red flag: Suggests embedding access keys in code

Cost Consciousness

Q: "You've inherited an AWS account with a $50K monthly bill. How do you approach optimization?"

Good answer:

  • Start with Cost Explorer analysis
  • Identify unused resources (idle EC2, unattached EBS)
  • Evaluate Reserved Instance opportunities
  • Consider architecture changes (serverless, right-sizing)

Common Hiring Mistakes

1. Over-indexing on Certifications

A developer with Solutions Architect Professional cert but no production experience will struggle. Prioritize hands-on experience over credentials.

2. Testing Console Knowledge

Clicking through the AWS console is different from writing Terraform. Modern infrastructure is code. Ask about IaC tools and practices.

3. Ignoring Cost Awareness

AWS makes it easy to overspend. Candidates who've never thought about cost optimization may rack up bills. Ask about their cost management experience.

4. Hiring Generalists When You Need Specialists

An EC2/ECS expert may not know Redshift deeply. Clarify which services matter for your use case and hire accordingly.

EKS/ECS Container orchestration services
IAM Identity and Access Management (security)
Terraform Infrastructure as Code tool

Frequently Asked Questions

Frequently Asked Questions

Treat certification as a positive signal, not a requirement. Certified candidates without production experience often struggle. Uncertified candidates with real architecture experience are usually stronger. Use certification as a tiebreaker, not a filter.
