Job description

Reflexive Concepts is seeking a skilled Software Engineer II (Full-Stack with UI) to join our team!
Reflexive Concepts is looking for a Full-Stack Software Engineer II with strong UI proficiency to join a small, high-impact development team. If you enjoy taking ideas from concept to working prototype in short, iterative cycles, and you like solving challenging problems across the stack, this role will give you the opportunity to have an outsized impact on how the organization operates. You will work as a hands-on engineer on a close-knit team, helping to design and build modern, scalable applications with polished, intuitive user interfaces. Work is performed in a contractor facility in Annapolis Junction.
Responsibilities:
  • Design, develop, maintain, and enhance complex, full-stack software systems based on documented requirements
  • Implement features end-to-end, from UI through backend services and data stores
  • Apply modern software engineering practices (version control, code reviews, automated testing, CI/CD) to deliver reliable and maintainable solutions
  • Build and execute simulations and test harnesses in development and test environments
  • Ensure UI designs adhere to established UX/UI principles, style guides, and accessibility standards
  • Leverage UI libraries, frameworks, and reusable components to accelerate development and maintain consistency
  • Test UI across approved browsers and platforms to ensure a seamless user experience
  • Debug and troubleshoot UI and full-stack issues, performing root-cause analysis and driving fixes
  • Continuously improve the user experience by identifying UX/UI enhancements and performance optimizations
  • Participate in code reviews, providing and receiving constructive feedback to maintain code quality and shared standards
  • Collaborate closely with product owners, designers, and other engineers to refine requirements and deliver incremental value
Requirements:
  • Active TS/SCI with Full-Scope polygraph
  • Bachelor's degree in Computer Engineering, Computer Science, Electrical Engineering, Math, or Physics - or an equivalent combination of education, training, and experience
  • Minimum 14 years of relevant experience in software engineering, modernization, or solution architecture
Required Skills:
  • Strong Java development skills for backend services
  • Proficiency with modern JavaScript frameworks, specifically React, for building rich, responsive UIs
  • Experience designing and consuming RESTful APIs
  • Hands-on experience with containers (Podman and/or Docker)
  • Experience with container orchestration platforms such as Kubernetes
  • Practical experience designing and building microservices-based architectures
Familiarity with Two or More of the Following:
  • Data and processing paradigms: machine learning, streaming data pipelines, and/or batch processing
  • Data stores: MongoDB, ArangoDB, Redis, PostgreSQL
Desired Skills:
  • Experience developing and deploying applications in cloud environments such as AWS or on hyper-converged infrastructure (HCI)
  • Familiarity with logging, monitoring, and observability tools for full-stack applications
  • Experience working in agile or iterative development environments
