About the Role

We're seeking an experienced Platform Engineer to own and evolve our AWS infrastructure. You'll design, build, and maintain the systems that enable our engineering teams to ship reliably. This is a hands-on role where you'll work across Kubernetes orchestration, infrastructure-as-code practices, cloud networking, and identity management. You'll balance strategic infrastructure improvements with operational excellence.

What we're looking for

You're someone who understands that infrastructure is a product for your internal users. You think holistically about reliability, security, and developer experience. You communicate technical concepts clearly to both engineers and leadership. You're comfortable making trade-offs between perfection and pragmatism, and you own the systems you build. You're curious about how things work under the hood and stay current with infrastructure trends.

Primary Responsibilities

Design, deploy, and manage Kubernetes clusters on AWS EKS with a focus on reliability, security, and cost efficiency

Develop infrastructure-as-code using Terraform, CloudFormation, or similar tools; maintain version control and CI/CD integration for all infrastructure changes

Architect and implement AWS networking solutions including VPCs, security groups, load balancing, and service mesh technologies

Design and implement identity and access management (IAM) strategies, including RBAC, service accounts, and cross-account access patterns

Establish observability and monitoring across infrastructure, troubleshoot production issues, and drive continuous improvement

Partner with development teams to enable self-service capabilities and reduce operational friction

Document architectural decisions and maintain runbooks for critical infrastructure

Required Qualifications

5+ years of experience with infrastructure engineering or equivalent platform engineering experience

Strong hands-on experience with Kubernetes (production deployments, resource management, troubleshooting)

Demonstrated expertise in infrastructure-as-code (Terraform, CloudFormation, or similar)

Solid understanding of AWS services, particularly EC2, ECS/EKS, RDS, S3, VPC, and related networking components

Deep knowledge of IAM principles and hands-on experience implementing least-privilege access controls

Experience with networking fundamentals (TCP/IP, DNS, TLS, load balancing, service mesh concepts)

Proficiency in at least one programming/scripting language (Go, Python, Bash, or similar)

Experience managing containers and container orchestration in production environments

Strong problem-solving skills and demonstrated ability to handle on-call escalations

Experience with service mesh technologies (Istio, Linkerd)

Familiarity with GitOps workflows and tools (ArgoCD, Flux)

Experience with observability and monitoring tools (Prometheus, Grafana, DataDog, New Relic)

Knowledge of security best practices for Kubernetes and AWS (pod security policies, network policies, SIEM integration)

Demonstrated comfort using Claude.ai or similar AI tools to enhance productivity and accelerate problem-solving

Experience with cost optimization and capacity planning in AWS

Involvement in on-call rotations and incident response experience

What you'll work with:

AWS services: EKS, EC2, RDS, S3, VPC, IAM, ALB/NLB, Route 53, CloudWatch

Infrastructure tools: Terraform, Kubernetes, Docker, Helm

Observability: CloudWatch, or similar monitoring/logging platforms

Collaboration tools: Git, CI/CD platforms, issue tracking systems

AI-assisted development: Claude.ai for code generation, documentation, and troubleshooting
