Requirements

~1 min read

BA/BS in Computer Science, Engineering, or equivalent hands-on experience

Strong verbal and written communication in English
Self-motivated; works well in a fast-paced, collaborative team
Eager to learn new tools and apply them quickly
Passionate about solving problems in a principled, elegant way
Comfortable both teaching and learning from teammates

AWS hands-on: EKS, ECR, IAM/IRSA, MSK, S3, ALB, VPC, Security Groups
Terraform: write modules, manage remote state, integrate with CI
Kubernetes: RBAC, ingress, network policies, HPA, resource tuning — cluster management via Rancher or K9s
Helm + Ansible: author charts and playbooks, manage versioning
Docker: multi-stage builds, image optimization
Linux/Windows systems administration

Bitbucket Pipelines, GitHub Actions, or TeamCity — write and maintain, not just use
ArgoCD: sync policy, health checks, rollback
PR-based deployments; no direct commits to main/prod

Prometheus, Grafana, CloudWatch, Elasticsearch — setup and maintain
Structured logging, alert routing, dashboard authoring

Least privilege: IAM, IRSA, K8s RBAC — no wildcard permissions
Secret management: External Secrets / AWS Secrets Manager, zero hardcoded credentials
Supply chain: dependency scanning (Blackduck / Snyk / Trivy), CVE triage by CVSS score
Network segmentation: private subnets, Security Groups, ingress/egress control
Working knowledge of ISO/IEC 27001 and SOC 2 Type II — access control, audit trail, change management
Familiar with CIS Benchmarks for Kubernetes and Linux hardening

Python and/or Go — scripting, tooling, automation
Able to read Node.js/TypeScript code to debug service issues independently

Actively uses AI coding tools (GitHub Copilot, Cursor, Claude) in daily workflow — writing scripts, Terraform modules, Helm templates, and debugging
Knows how to prompt effectively, verify AI output, and not blindly trust generated infrastructure code

Experience in the cybersecurity industry
Knowledge of compliance frameworks: NIST CSF, HIPAA, GDPR — applied to real infrastructure
Istio: mTLS, VirtualService/DestinationRule, traffic management
KEDA advanced: custom metrics, scale-to-zero, cooldown tuning
Kafka (MSK) operations: topic management, consumer lag, AKHQ
Policy-as-code: OPA/Gatekeeper or Kyverno
OWASP container and API security principles
Coralogix / Datadog with OpenTelemetry — custom pipelines, alert routing
Kubecost cost analysis, Kubeshark traffic capture
Experience with large-scale systems: 30M+ requests/day
Azure exposure (secondary to AWS)
Has used AI to generate, review, or optimize infrastructure-as-code (Terraform, Helm, bash scripts) and understands its limitations: hallucinations, outdated API references, security blind spots
Experimented with AI APIs (OpenAI, Anthropic) to build internal automation or tooling
