Mid-level Software Engineer - TS Required

• Java & Spring: You need to be deep in the Spring ecosystem (Boot, Data, Security). We are using modern versions, so familiarity with Spring Boot 3 features is expected.
• Cloud & Containers: We are deploying to AWS. You should have a solid understanding of how to containerize services with Docker and manage them within a Kubernetes environment.
• Automation: We use GitLab CI/CD for the entire lifecycle. You will be responsible for writing and maintaining the pipelines that build, test, and deploy your code.
• The Conversion: You will work with SMEs to extract business logic from legacy systems and architect the new Java-based services. You don't need to know the legacy languages, but you must be able to translate complex requirements into clean, modular code.

Daily Workflow

• Architect and develop microservices using Spring Boot.
• Own and maintain GitLab CI/CD pipelines to ensure high-velocity deployments.
• Design RESTful APIs that are scalable, secure, and well-documented.
• Lead technical design sessions to determine how the new baseline handles scale and performance on AWS.
• Maintain high test coverage with JUnit and Mockito to ensure the new system is more resilient than the one it is replacing.

• 5+ years of professional software development experience with a focus on Java (3+ years with a Masters)
• Proven experience of Spring Boot and its core modules.
• Experience with Git, GitLab CI/CD, and containerization.
• Bachelor's degree in Computer Science or a related technical field.
• Active Top Secret (TS) clearance and willingness to undergo a CI Polygraph.

Location: Chantilly, VA (100% On-site / Secure Facility) Clearance: Active Top Secret (TS) required; must be willing to sit for a CI Polygraph Salary: 155k-185k (up to 195k for exceptional candidates already possessing a CI Polygraph)

The Project We are re-engineering a core software baseline from the ground up. This isn't a migration of existing Java code; it is a full rewrite of legacy components into a modern, distributed architecture. The goal is a clean-room implementation designed to run natively on AWS using Kubernetes for orchestration. Due to the nature of the mission and the secure facility, this role is 100% on-site in Chantilly.
