Using feature driven development, you will build, test, and deploy scalable web applications that directly support the Computer Network Operations (CNO) mission. If you want to collaborate closely with technical leaders, have a real voice in product roadmaps, and work with a modern tech stack, this is the perfect place to grow your career.

• Collaborate on Design: Work hand-in-hand with the Technical Lead to make key architectural decisions, solve complex design problems, and shape the product roadmap.
• Engage with the Mission: Interact directly with customers and operators daily to troubleshoot issues, gather feedback, and propose innovative new features.
• Ensure Quality: Support the end-to-end testing, continuous integration, and deployment of production ready applications.

What you need to have

• Experience:
• 3 or more years of software engineering experience with a Bachelor's degree in a technical discipline.
• Or 7 or more years of experience (substituting 4 years of additional engineering experience in place of a Bachelor's degree).

• Modern Frameworks: Proven experience building and maintaining RESTful web applications using Spring Boot.

• Full-Stack Capabilities: Experience with UI development using modern JavaScript frameworks, specifically Vue.js.
