What Is a Full Stack Java Developer?

A full stack Java developer is a web developer that uses the Java language in the development of the entire technology stack of a web-based application. The job duties of a full stack Java developer are to create both front-end components, such as user interfaces and back-end components, such as application code and databases. As a full stack Java developer, you must understand how the entire technology stack functions as a whole and have deep expertise of each component. Java is a computer programming language that has become one of the most popular for web application development.

What are the key skills and qualifications needed to thrive as a Full Stack Java Developer, and why are they important?

To thrive as a Full Stack Java Developer, you need strong proficiency in Java, front-end frameworks (such as Angular or React), back-end technologies, and a solid understanding of databases, often supported by a degree in computer science or a related field. Familiarity with version control systems like Git, build tools such as Maven or Gradle, and knowledge of Spring Boot or similar frameworks are typically required, along with relevant certifications. Effective communication, problem-solving abilities, and adaptability are standout soft skills in this role. These skills and qualities are essential to deliver robust, user-friendly applications and to collaborate efficiently across the software development lifecycle.

What are the typical challenges Full Stack Java Developers face when working on cross-functional teams?

Full Stack Java Developers often collaborate with front-end designers, back-end engineers, and QA specialists, which can lead to challenges in aligning technical requirements, timelines, and coding standards. Navigating different priorities and communication styles is common, especially when integrating new features or resolving bugs that span both client and server sides. Success in this environment requires flexibility, proactive communication, and a willingness to quickly adapt to shifting project needs or technologies.

Job description

Job Description
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
  • 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 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.

Requirements
  • 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.
  • Ability to obtain or maintain a government security clearance.
  • Prior DoD or federal experience is strongly preferred.

This position is eligible for remote work in the St. Louis area. However, the position requires a government security clearance, so candidates must be U.S. citizens and eligible for work without a visa sponsorship.
Benefits
  • Competitive Salary
  • Paid Time Off
  • Paid Federal Holidays
  • 401K with matching
  • 100% Paid Medical, Dental, Vision, Long & Short Term Disability, and Basic Life
  • Flexible Spending Account
  • Health Reimbursement Arrangement
  • Work From Home Options
  • Education Assistance
