• Architect and implement microservices, serverless
  functions, and containerized workloads using AWS services such as Lambda,
  ECS, EKS, Fargate, and API Gateway.
  
• Build and optimize data models, SQL queries, and
  relational database operations.
  
• Participate in architecture reviews, design sessions,
  and backlog refinement.
  
• Conduct code reviews and refactor existing backend
  components for scalability, maintainability, and security.
  
• Integrate backend services into CI/CD pipelines with
  automated builds, tests, and scans.
  
• Ensure secure coding practices and interpret output
  from static and dynamic security analysis tools.
  
• Use scripting languages, including Python and Bash, to
  automate operational and deployment tasks.
  
• Troubleshoot complex backend issues across application
  logic, integrations, data stores, and cloud resources.
  
• Mentor team members in API design, backend
  architecture, and secure coding patterns.
  

What we like to see

• Deep experience with Java and .NET development in
  production environments.
  
• Strong understanding of REST API design, service
  versioning, and integration testing.
  
• Experience deploying and managing backend services in
  AWS using Lambda, ECS, ECR, CloudFormation, RDS, S3, CloudWatch, and IAM.
  
• Experience with microservices or modular service
  architectures.
  
• Strong debugging skills in distributed systems.
  
• Experience working within DoD or regulated environments
  with security compliance requirements.
  
• Comfortable working with minimal day-to-day direction
  and accountable for end to end delivery.
  

You should be familiar with

• Java (Spring Boot or similar frameworks) and .NET (Core
  or Framework).
  
• SQL and relational database design.
  
• Linux administration and scripting.
  
• Containerization with Docker and orchestration
  patterns.
  
• CI/CD tooling such as Jenkins, GitHub Actions, or

  integration, including HTML, CSS, and JavaScript.
  
• OpenAPI Spec 3.x and automated code generation
  
• Agile methodology.
  

Requirements

• Minimum Experience: 5+ years of professional
  development, including at least 3 years of Java development.
