External Description:

Job Description: Senior AWS DevOps Engineer (100%
Hands-on)
We are seeking a high-octane, 100% hands-on AWS DevOps Engineer to join our
engineering team. This is not an architectural or high-level strategy role; we need a "builder"
who thrives in the terminal, writes clean Infrastructure as Code, and can manage the
end-to-end lifecycle of production-grade ML and data platforms.
The ideal candidate has deep expertise in Kubernetes (EKS) and a proven track record of
automating complex MLOps workflows. AWS Certifications are a significant plus.

### Core Responsibilities (The "Must-Haves")
● EKS Mastery: Lead the end-to-end implementation and day-to-day operations of
Amazon EKS, including cluster provisioning, networking, and hosting complex
microservices/apps.
● Infrastructure as Code: Maintain and scale our environment using Terraform as the
primary provider.
● MLOps Pipeline Engineering: Build and manage CI/CD pipelines specifically for Machine
Learning, including automated model registry updates, feature store synchronization, and
automated deployments.
● Cloud Security & Identity: Implement rigorous IAM best practices specifically for ML
workloads and ensure data isolation through VPCs, subnets, and private endpoints.
● Data Persistence & Governance: Manage S3 (lifecycle policies, performance tiering),
Secrets Manager, KMS encryption, and Parameter Store.
● Observability: Own the monitoring stack using CloudWatch, Prometheus, and Grafana to
ensure system health and proactive alerting.

### Technical Requirements & Skills
Infrastructure & Platforms:
● Primary: Amazon EKS, Terraform, Airflow (Orchestration).
● Secondary: Kubeflow or equivalent MLOps tooling.
Database & Analytics:
● Relational: RDS/Aurora (PostgreSQL/MySQL).
● NoSQL: DynamoDB (expert-level capacity planning and data modeling).
● Data Engineering: AWS Glue (ETL), EMR (EMR on EKS/Serverless).
Machine Learning Operations:

● Deep experience with Amazon SageMaker (training jobs, endpoints, pipelines, and
notebooks).

### Engineering Principles
We expect you to live and breathe the AWS 5 Pillars (The Well-Architected Framework):
1. Cost Optimization: Proactive management of cloud spend.
2. Performance Efficiency: Selection of evolved resource types based on workload.
3. Reliability: Designing for recovery and change management.
4. Resiliency: Implementing Multi-AZ/Multi-Region patterns.
5. Security: Operating under the principle of Least Privilege and cloud security best
practices.

### Qualifications
● Minimum 5+ years of experience in an AWS DevOps or Site Reliability role.
● Proven experience supporting Data Science teams and ML production environments.
● Ability to troubleshoot complex networking and container orchestration issues in
real-time.
● Must be 100% hands-on.
