Cloud Engineer SME

Job Description

We are seeking a highly skilled Cloud Engineer Subject Matter Expert (SME) to join our team. The Senior Cloud Engineer (Cloud Engineer SME) is the senior technical implementation lead responsible for designing, building, and operationalizing secure, scalable AWS-based environments supporting modernization of complex, interdependent systems.

This role requires deep AWS engineering expertise and advanced Python development skills, as well as active participation in discovery, legacy system analysis, and phased migration planning. The Cloud Engineer SME will work closely with the Systems Architect and Technical Program Manager to assess existing environments, design migration-ready architectures, and implement cloud-native solutions aligned to modernization sequencing and governance requirements.

This is not a pure infrastructure role — the Cloud Engineer SME must be capable of analyzing legacy systems, evaluating migration paths, and translating architectural strategy into deployable cloud solutions.

Write production-quality Python code with testability, logging, secure coding practices, and modular design. Review and support Python refactoring patterns during legacy modernization. Ensure Python runtime environments are reproducible and aligned with CI/CD standards. Embed quality and compliance gates into pipelines. Automate environment provisioning and deployments. Ensure version-controlled infrastructure and reproducible deployments.

• Discovery, Legacy Analysis & Migration Planning
• Participate in structured discovery efforts across legacy systems.
• Analyze existing application architectures, infrastructure dependencies, batch schedules, data flows, and integration points.
• Contribute to formal system inventory documentation.
• Identify cloud readiness gaps and modernization constraints.
• Support classification of systems using the 7 Rs migration framework.
• Provide technical input into phased migration roadmaps and sequencing plans.
• Assess operational risk, integration complexity, and environment dependencies during modernization planning.
• Document current-state (As-Is) technical architecture and assist in defining target-state (To-Be) environment patterns.
• Cloud Infrastructure & Environment Engineering
• Design and implement AWS cloud environments aligned to enterprise provisioning constraints.
• Develop and maintain Infrastructure-as-Code (IaC) using Terraform or Cloud Formation.
• Establish repeatable environment patterns for development, testing, staging, and production.
• Implement secure network architecture (VPC segmentation, IAM least privilege, encryption).
• Design for high availability, resiliency, and disaster recovery.
• Align environment provisioning with migration waves and modernization sequencing.
• Python Engineering for Cloud-Native Applications (Required)
• Develop and maintain Python-based cloud components including:
• Serverless functions
• Orchestration utilities
• Data validation and transformation scripts
• Automation tooling
• Cloud-Native Application Enablement
• Implement scalable AWS compute solutions (Lambda, ECS/EKS/Fargate, Glue, Aurora/PostgreSQL, S3, Batch).
• Evaluate serverless vs containerized approaches based on workload characteristics.
• Support refactoring efforts by providing optimized cloud runtime patterns.
• Improve performance, scalability, and observability for data-intensive workloads.
• Dev Sec Ops  & CI/CD Implementation
• Design and implement CI/CD pipelines integrating:
• Automated builds
• Unit and integration tests
• Regression validation
• Security scanning
• Observability & Operational Readiness
• Implement monitoring, logging, and alerting standards.
• Establish performance baselines and capacity thresholds.
• Support load testing and scalability validation
