Software Engineer with Security Clearance

U.S. Citizenship Required. Ability to qualify for a US Department of War security clearance required. This is an on-site position located in Ashburn, VA. Build Modern, Mission-Critical Systems with Room to Grow Toyon is seeking an intermediate-level Software Engineer to help design and deliver modern, server-based applications supporting high-impact initiatives. This is not a legacy maintenance role — you’ll be working on actively evolving systems with a clear modernization roadmap, including a future strategic move towards more Kotlin-based development.

You’ll collaborate directly with a small, highly skilled engineering team and client stakeholders, contributing across the full software development lifecycle — from requirements and architecture through deployment and client demonstrations. Because our team is intentionally lean, your contributions will have visible impact, and you’ll have the opportunity to expand your technical footprint beyond backend development over time. This is an ideal role for a Java developer who wants more ownership, broader exposure, and a pathway into emerging technologies. What Makes This Role Different

• Modernization Focus: Work on actively evolving systems with a roadmap toward future Kotlin adoption
• Growth Beyond Backend: Opportunities to expand into front-end development (React), relational database design, and system architecture
• High Visibility: Small team environment where your work directly influences product direction
• Full Lifecycle Ownership: Participate in design, implementation, deployment, demos, and client engagement
• Mission-Driven Impact: Support clients with solutions that matter

What You’ll Do

• Collaborate with engineering team members and client stakeholders to gather and refine requirements
• Design and develop scalable, maintainable server-side applications using Java (17+) with an evolving Kotlin roadmap
• Contribute to architectural discussions, mockups, prototypes, and system enhancements
• Implement features and improvements using modern development practices
• Perform testing, debugging, and deployment to production environments
• Support client-facing demonstrations, presentations, and training sessions
• Participate in both office-based and on-site implementation efforts Requirements
• Education: Bachelor’s degree in Computer Science, Information Systems, or related field — or equivalent professional experience
• Java Expertise: 2+ years of professional experience with Java 17+ and strong object-oriented design skills
• Databases: Solid understanding of relational database concepts and proficiency in SQL.
• Development Tools: Experience with Git, Maven, and a modern IDE (Eclipse, IntelliJ, or similar)

Preferred Experience

• Familiarity with Spring Boot 3.x for building enterprise applications.
• Experience designing or consuming RESTful APIs
• Interest in Kotlin or modern JVM language evolution
• Exposure to front-end technologies such as React (or interest in expanding into front-end work)

Who Thrives Here This role is a strong fit for engineers who:

• Want more than a narrowly defined coding role
• Enjoy learning new technologies and expanding their skill set
• Prefer working on a small, agile team rather than being a small cog in a large organization
• Are motivated by meaningful, long-term projects rather than short-lived feature work

If you're a Java developer ready to grow, expand your architectural influence, and broaden your technical scope into front-end and database design, we’d love to talk with you. WE OFFER AN EXCEPTIONAL EMPLOYEE BENEFITS PACKAGE!
