Job description

Java Developer

We are seeking a Java Developer to support a command and control system for the Mobility Air Force. This role focuses on designing and maintaining mission critical backend services in Java and .NET, building and securing RESTful APIs, and implementing cloud native patterns in Amazon GovCloud. You will work across the entire stack, but your primary responsibility will be backend architecture, service reliability, data integrity, and integration with cloud services.

You will operate within an Agile environment and mentor junior developers while contributing to evolving DevSecOps pipelines and secure deployment practices.

What you will do:

  • Design, implement, test, and deploy backend features using Java and .NET in AWS GovCloud.
  • Lead the development of RESTful services, API endpoints, and backend integration patterns.
  • 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:

  • ava (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 GitLab CI.
  • Cloud networking, IAM policies, and secure cloud deployment models.
  • Basic front end technologies for full stack integration, including HTML, CSS, and JavaScript.
  • OpenAPI Spec 3.x and automated code generation
  • Agile methodology

Qualifications:

  • Minimum Experience: 3+ years of professional development, including at least 3 years of Java development.
  • Experience owning backend services or components in production.
  • Bachelor’s degree in Computer Science, Engineering, or related field, or equivalent experience.
  • Prior DoD or federal experience is strongly preferred.
  • Must be eligible to obtain and maintain a US Security Clearance
