Full Stack Software Engineer

The Full Stack Software Engineer will support the design, development, modernization, testing, and sustainment of AET's secure mission software products. This position contributes across the full application stack, including user interface components, backend services, API layers, integration and messaging services, relational databases, automated testing, and deployment-support activities.

The engineer will help AET evolve its software products and engineering practices toward a more scalable, secure, AI-enabled, and well-documented product organization. The individual will work with Product Ownership, Mission Systems Engineering, QA, Operations, Program Management, and technical leadership to translate customer, mission, and product needs into maintainable software capabilities.

Primary responsibilities include:

Design, develop, unit test, integrate, and maintain Java and JavaScript-based software capabilities.
• Support message transformation, routing, and integration involving XML, JSON, custom message formats, and mission-specific data exchange patterns.
• Contribute to enhancements, defect resolution, refactoring, and technical debt reduction within AET's existing product baseline.
• Participate in product planning, backlog refinement, technical design discussions, code reviews, implementation, integration testing, release preparation, and post-release support.
• Support Git-based workflows, CI/CD improvements, automated testing, static analysis, dependency review, SBOM generation, security scanning, build automation, release quality gates, and repeatable deployment-support practices.
• Use AI-assisted engineering tools responsibly to improve productivity in code analysis, test generation, documentation, troubleshooting, refactoring support, and workflow automation.
• Support the interface between software development and Mission Systems Engineering by investigating field-reported issues, reproducing defects, evaluating operational feedback, supporting release packaging, and improving product supportability.
• Document design decisions, implementation notes, troubleshooting procedures, support-relevant technical information, build and release practices, test approaches, and lessons learned.

• Years of Experience: Minimum of 5 years of professional software engineering experience; exceptional candidates with 3+ years of highly relevant full-stack, integration, or secure systems experience may be considered
• Backend: Strong Java development experience; ability to work on existing Java codebases and modernize/refactor safely
• Frontend: JavaScript and preferably TypeScript; experience with modern web UI development
• Full Stack Delivery: Ability to work from UI through API/service layer, integration/messaging components, and database persistence
• Integration: Experience with REST APIs, XML, JSON, message transformation, schema-driven data exchange, and custom message formats
• Databases: SQL and relational database experience, such as MySQL, PostgreSQL, SQL Server, or Oracle
• Platforms: Comfortable developing and troubleshooting on Linux and Windows
• Development Workflow Tools: Experience using Jira, Confluence, GitHub, GitLab, Bitbucket, or equivalent tools for issue tracking, documentation, source control, code review, and team coordination
• Source Control: Git experience, including branching, pull requests, code review, and disciplined commit practices
• Testing: Unit testing, integration testing, debugging, and defect resolution
• Remote Work: Proven ability to work effectively in a mostly remote, geographically dispersed team
• Communication: Ability to explain technical work clearly to product owners, Mission Systems Engineering, QA, support, and leadership

Desired Experience

• Secure Messaging / Integration: Experience with enterprise messaging, message brokers, ESB/integration frameworks, Apache Camel, Mule, JMS, AMQP, RabbitMQ, ActiveMQ/Artemis, or similar technologies
• Defense / IC Environment: Experience supporting DoD, IC, federal, or classified software environments
• DevSecOps: CI/CD pipelines, automated analyzers, SBOM generation, security scans, build gates, and release automation
• Containers: Docker or containerized development/test environments; Kubernetes helpful but not mandatory
• Knowledge Capture: Willingness to document design decisions, support runbooks, troubleshooting procedures, and engineering practices
• Product Mindset: Experience balancing roadmap work, customer issues, defects, technical debt, and release readiness
• Quality Systems: Familiarity with ISO/QMS, configuration control, change control, or regulated development practices
• Security Mindset: Familiarity with least privilege, auditability, secure coding, dependency risk, vulnerability remediation, and controlled release practices
