CyberGate Defense is seeking a Senior Cloud & Application Modernization Engineer to lead secure scalable transformation of legacy systems into modern cloud-native architectures across multi-cloud environments with strategic emphasis on AWS, Oracle Cloud, and Microsoft Azure.

The ideal candidate will combine expertise in containerization (Docker/Kubernetes), SharePoint development, API-driven integrations, and cloud security to accelerate digital transformation initiatives. This role moves beyond traditional DLP and MDM focusing instead on modern application delivery, secure DevOps, and resilient hybrid-cloud solutions for defense and government clients.

Key Responsibilities

• Modernize legacy applications by refactoring and containerizing (Docker) and orchestrating workloads using Kubernetes (AKS, EKS, OKE) across Azure, AWS, and Oracle Cloud.
• Design, develop, and deploy custom SharePoint Online solutions including SPFx web parts, Microsoft Graph integrations, Teams embeds, and secure collaboration sites.
• Implement secure API architectures (REST/GraphQL) with authentication (OAuth 2.0, Entra ID, AWS Cognito, Oracle IDCS), rate limiting, and monitoring.
• Conduct multi-cloud security gap assessments aligned with ISO 27001, NIST, and CIS benchmarks; deliver prioritized remediation roadmaps.
• Enforce cloud-native security controls:
  • Identity & access (Entra ID, AWS IAM, Oracle IAM)
  • Network policies (NSGs, Security Groups, OCI NSGs)
  • Secrets management (Azure Key Vault, AWS Secrets Manager, Oracle Vault)
  • Container image scanning and runtime protection
• Automate provisioning, configuration, and compliance using Infrastructure-as-Code (Terraform, ARM, CloudFormation) and scripting (Python or PowerShell).
• Build custom monitoring and compliance dashboards (e.g., Power BI, Grafana, native cloud tools) to track application health, security posture, and modernization KPIs.
• Embed security into CI/CD pipelines (Azure DevOps, AWS CodePipeline, Oracle DevOps) with automated testing, dependency checks, and policy gates.
• Collaborate with architects, developers, and compliance teams to ensure secure, scalable, and maintainable application designs.
• Evaluate and integrate third-party services via secure API consumption and publishing patterns.

Mandatory Requirements

• 68 years of experience in cloud engineering, cybersecurity, or application modernization with hands-on work across at least two of: Microsoft Azure, AWS, Oracle Cloud.
• Proven SharePoint development expertise:
  • Modern SharePoint Online (SPFx, Microsoft Graph REST APIs)
  • Integration with Power Platform, Teams, and Entra ID
• Strong experience with Docker and Kubernetes:
  • Building, securing, and deploying container images
  • Managing clusters (AKS/EKS/OKE), Helm charts, ingress/egress controls
• Demonstrated experience in application modernization (e.g., monolith-to-microservices, API-first design, event-driven architectures).
• Solid understanding of Zero Trust, identity-centric security, and data protection in cloud-native apps.
• Experience performing cloud security gap assessments and delivering remediation roadmaps aligned with compliance standards.

Preferred Qualifications (Added Advantage)

• Scripting & automation proficiency in Python and/or PowerShell (e.g., automating deployments, log parsing, API calls).
• API design and integration experience:
  • RESTful services, OpenAPI/Swagger
  • API gateways (Azure API Management, AWS API Gateway, Oracle API Gateway)
• Relevant certifications such as:
  • CKA / CKAD (Certified Kubernetes Administrator/Developer)
