2️⃣ Must‑Have Technical Skills (✓ = essential)

Skill	Why it matters for the role
AWS networking – VPC, Subnets, Route Tables, NAT, TGW, Direct Connect, Route 53, hybrid connectivity	Core of the job – you’ll design and maintain the whole network fabric.
Terraform (or other IaC)	Required to build repeatable, version‑controlled environments.
Python / Go scripting	Needed for automation, custom Lambda functions, or tooling around Terraform/CI‑CD.
AWS security services – IAM, SG, NACL, WAF, GuardDuty	UST emphasizes “secure, scalable” clouds.
CI/CD pipelines (Jenkins, GitHub Actions, CodePipeline, etc.)	To push IaC changes automatically.
Linux/Unix administration	Underlying OS for most AWS workloads and automation scripts.
Networking fundamentals – DNS, BGP, routing, latency troubleshooting	Directly tied to the “troubleshoot complex networking issues” responsibility.

---

3️⃣ Nice‑to‑Have / Preferred Extras

Skill	How to showcase it
Multi‑account AWS environments (AWS Organizations, Control Tower)	Mention any landing‑zone or cross‑account automation you built.
Hybrid cloud connectivity (VPN, Direct Connect, SD‑WAN)	Highlight any on‑prem ↔ AWS integrations you’ve delivered.
DevOps culture (GitOps, automated testing, policy as code)	Cite examples of using tools like OPA, Sentinel, or Checkov.
Cloud governance frameworks (AWS Well‑Architected, CIS Benchmarks)	Note any compliance audits you’ve passed or frameworks you’ve implemented.
Other IaC tools (CloudFormation, CDK, Pulumi)	Shows flexibility; list if you have experience.
Monitoring & Logging (CloudWatch, CloudTrail, ELK, Prometheus)	Mention dashboards or alerting pipelines you built.

4️⃣ Sample Resume Bullets (Tailor to your own experience)

AWS Cloud Networking Engineer – XYZ Corp (2021‑Present)
• Designed and deployed a multi‑region, multi‑account AWS network using Transit Gateway, VPC peering, and Direct Connect, reducing inter‑VPC latency by 30 % and cutting VPN costs by $45 K/yr.
• Built a Terraform‑based landing‑zone (AWS Organizations, Control Tower) that provisioned new accounts in under 15 min, with automated guardrails for IAM, Security Groups, and GuardDuty.
• Implemented Infrastructure‑as‑Code pipelines in GitHub Actions that run terraform plan/apply with automated policy checks (Checkov, Sentinel), achieving zero‑drift environments across 12 production accounts.
• Developed Python automation scripts for bulk security‑group remediation and for generating Route 53 health‑check reports, decreasing manual effort by 80 %.
• Integrated AWS WAF, Shield, and GuardDuty with centralized logging to Splunk; created dashboards that cut mean‑time‑to‑detect (MTTD) security events from 4 h to 15 min.
• Conducted root‑cause analysis of DNS‑routing incidents, applying BGP troubleshooting and VPC flow‑log analysis to resolve latency spikes within 30 min.

Cloud Infrastructure Engineer – ABC Ltd (2017‑2021)
• Automated provisioning of VPCs, subnets, NAT gateways, and Route 53 zones using Terraform; managed state with S3 + DynamoDB locking.
• Built CI/CD pipelines (Jenkins + Terraform) for nightly infrastructure validation, reducing configuration drift to < 1 %.
• Authored Go micro‑service that queried AWS Config to enforce tagging policies, achieving 100 % compliance across 25 accounts.
• Designed and maintained Hybrid connectivity via Site‑to‑Site VPN and Direct Connect, supporting a 5 TB/month data pipeline between on‑prem data‑center and AWS.

5️⃣ Cover‑Letter Paragraph (One‑paragraph hook)

I am excited to apply for the Cloud Engineer – AWS Networking & Infrastructure role at UST. With 7 years of experience building secure, highly‑available AWS environments—most recently architecting a multi‑account, Transit‑Gateway‑centric network for a global SaaS platform—I have a proven track record of delivering the exact capabilities you describe: end‑to‑end VPC design, Terraform‑driven IaC, and rigorous security controls (IAM, GuardDuty, WAF). My hands‑on work with Python automation, CI/CD pipelines, and hybrid connectivity (Direct Connect & VPN) aligns perfectly with UST’s focus on resilient, compliant cloud solutions. I look forward to bringing my expertise in cloud networking, governance, and DevOps culture to help UST’s clients accelerate their digital transformation.

6️⃣ Interview Prep – Quick Cheat‑Sheet

Topic	Sample Question	Key Points to Mention
VPC design	“How would you design a VPC for a multi‑tier web app with public & private subnets?”	Public subnet for ALB/NAT, private subnets for app/DB, route tables, NACLs, SGs, use of NAT Gateway for outbound, VPC endpoints for S3/ DynamoDB.
Transit Gateway vs. VPC Peering	“When would you choose TGW over VPC peering?”	TGW for hub‑spoke, many‑to‑many, centralised routing, easier scaling, reduces route‑table limits.
Terraform state management	“How do you protect Terraform state in a multi‑account environment?”	Store in S3 with versioning + DynamoDB lock table, use workspaces or separate backends per environment, enable encryption.
Security	“Explain how you’d implement a least‑privilege IAM strategy for a new account.”	Use AWS Organizations SCPs, IAM permission boundaries, role‑based access, MFA, rotate keys, enable GuardDuty/Config.
CI/CD	“Describe your CI/CD pipeline for IaC.”	Git repo → PR → Terraform fmt/validate → plan (review) → policy check (Checkov) → apply on merge via GitHub Actions/Jenkins, with notifications.
Hybrid connectivity	“What are the trade‑offs between Direct Connect and VPN?”	Direct Connect: higher bandwidth, lower latency, dedicated link, higher cost, longer provisioning. VPN: quick, lower cost, uses internet, encryption overhead.
Troubleshooting	“A user reports high latency accessing an RDS instance in another region. How do you investigate?”	Check VPC flow logs, Route 53 latency‑based routing, TGW route tables, BGP health, CloudWatch metrics, cross‑region replication, DNS resolution.
Governance	“How do you enforce compliance across many AWS accounts?”	Use AWS Control Tower, Service Catalog, Config Rules, GuardDuty, automated remediation via Lambda, centralised logging (CloudTrail + S3 + Athena).
