DevOps to $3000

About the Role

We're looking for a hands-on Senior DevOps Engineer to own our entire cloud infrastructure on AWS and drive engineering velocity through world-class CI/CD pipelines. You'll be the go-to person for reliability, scalability, security, and developer experience across our high-traffic e-commerce platform handling millions of transactions monthly.

You'll work directly with engineering and product teams to ensure infrastructure scales predictably during peak traffic (flash sales, holidays), maintaining 99.9%+ uptime while keeping costs optimized.

Overview

• Department: Engineering / Infrastructure
• Reports to: CTO / VP Engineering
• Location: Remote (EU/US timezone preferred)
• Experience: 4–8 years in DevOps / Platform Engineering
• Employment: Full-Time

Core Stack

AWS · Terraform · GitHub Actions · Docker · Kubernetes (EKS) · PostgreSQL/Aurora · Redis/ElastiCache · CloudFront · Datadog · ArgoCD

Key Responsibilities

AWS Infrastructure

• Architect, provision, and maintain production AWS infrastructure across multi-AZ, multi-region setups using Terraform
• Manage and optimize ECS/EKS, RDS Aurora, ElastiCache, S3, CloudFront, ALB, Route 53, WAF, SQS/SNS
• Design and enforce VPC architecture, security groups, IAM roles following least-privilege principles
• Implement auto-scaling strategies for flash-sale traffic spikes (EC2 ASGs, ECS task scaling, Lambda concurrency)
• Own infrastructure costs — right-sizing, reserved instance planning, Savings Plans analysis
• Manage secrets and configuration via AWS Secrets Manager and Parameter Store

CI/CD & Developer Experience

• Design and maintain end-to-end CI/CD pipelines (GitHub Actions / GitLab CI) for microservices, frontend, and mobile backends
• Implement blue/green and canary deployments with automated rollback triggers
• Build reusable pipeline templates and shared actions to accelerate developer velocity
• Manage multi-environment promotion workflows (dev → staging → production) with environment-specific gating
• Maintain Docker build pipelines with layer caching, vulnerability scanning (Trivy/Snyk), and ECR lifecycle policies
• Implement feature flag infrastructure for zero-downtime releases

Kubernetes & Container Orchestration

• Administer EKS clusters: node groups, cluster upgrades, add-on lifecycle (CoreDNS, CNI, cluster-autoscaler)
• Design Helm chart templates and ArgoCD manifests for all services
• Implement HPA, VPA, and KEDA for event-driven scaling
• Manage ingress controllers (AWS ALB / NGINX) and certificate management (cert-manager, ACM)
• Enforce resource quotas, network policies, and pod security standards

Observability & Reliability

• Own the full observability stack: metrics (Datadog / Prometheus + Grafana), logs (OpenSearch / CloudWatch), traces (X-Ray / Jaeger)
• Build dashboards and SLO/SLA alerting for critical e-commerce flows (checkout, payment, inventory)
• Lead incident response, runbook creation, and post-mortem culture
• Implement chaos engineering to proactively identify reliability gaps
• Define and track error budgets, MTTR, and deployment frequency as core KPIs

Security & Compliance

• Implement and maintain AWS GuardDuty, Security Hub, Config Rules, Inspector
• Manage SSL/TLS lifecycle, WAF rule sets, and DDoS mitigation via AWS Shield
• Conduct regular security reviews and remediate findings from automated scanning
• Ensure PCI-DSS readiness for payment infrastructure; support SOC 2 audit evidence collection
• Implement secrets rotation, KMS encryption at rest, and encryption in transit

Database & Data Infrastructure

• Manage RDS Aurora PostgreSQL: parameter tuning, read replicas, failover testing
• Administer ElastiCache Redis clusters for session storage and catalog caching
• Own backup strategies, PITR configuration, and DR runbooks
• Collaborate with engineering on connection pooling (PgBouncer/RDS Proxy) and schema migrations

Disaster Recovery

• Design and maintain RTO/RPO targets; conduct quarterly DR drills
• Implement cross-region replication for S3, RDS, and ElastiCache
• Maintain IaC for rapid environment recreation; document runbooks for all critical failure scenarios

Requirements

Must-have:

• 4+ years of hands-on DevOps/SRE/Platform Engineering in production e-commerce or high-traffic SaaS
• Deep AWS expertise — Solutions Architect or DevOps Engineer certification (Professional level preferred)
• Strong Terraform proficiency: module design, state management, Atlantis or Terraform Cloud
• Production EKS experience: cluster operations, Helm, GitOps with ArgoCD or Flux
• CI/CD pipeline expertise with GitHub Actions, GitLab CI, or equivalent
• Solid scripting in Bash and Python
• Docker multi-stage builds, image optimization, and container security scanning
• Strong networking fundamentals: VPC design, subnetting, routing, DNS, load balancing, CDN
• Observability experience: Datadog, Prometheus/Grafana, or equivalent
• Production PostgreSQL and Redis management
