This role focuses on building modern, responsive, and data-rich user interfaces that consume real-time information from distributed backend systems. The successful candidate will have deep expertise in JavaScript and TypeScript development, experience building sophisticated front-end applications, and a strong understanding of how front-end systems interact with microservices, streaming platforms, and cloud-native architectures. You will work closely with backend engineers, architects, and mission stakeholders to build intuitive applications capable of processing and displaying large volumes of information in near real-time. Success in this role requires a strong understanding of asynchronous programming, concurrency patterns, API integration, and modern front-end development practices. We use Svelte as its primary front-end framework. Prior Svelte experience is highly desired but not required for candidates with strong modern JavaScript framework expertise and a willingness to learn. Key Responsibilities • Design, develop, and maintain modern cloud-native front-end applications using JavaScript, TypeScript, and contemporary web technologies. • Build highly intuitive user experiences that support mission-critical situational awareness and collaboration workflows. • Develop efficient client-side applications capable of handling large data sets, concurrent requests, and near real-time information updates. • Integrate front-end applications with RESTful APIs, WebSocket services, and distributed backend systems. • Collaborate closely with backend engineers to consume services and leverage event-driven architectures, including Kafka-based data streams. • Implement performant asynchronous data loading strategies utilizing promises, concurrency patterns, and modern browser capabilities. • Optimize application performance, responsiveness, and scalability across multiple operating environments. • Participate in architecture discussions and contribute to technical design decisions. • Conduct code reviews and promote software engineering best practices. • Mentor junior developers and contribute to the overall growth of the engineering team. • Participate in Agile ceremonies and continuous improvement initiatives. Required Qualifications • Minimum of 7 years of professional software development experience, with a strong focus on front-end engineering. • Advanced proficiency in JavaScript and TypeScript. • Experience developing and deploying applications within Linux-based environments. • Strong experience building modern web applications and user interfaces. • Experience consuming and integrating RESTful web services and APIs. • Strong understanding of asynchronous programming concepts, including Promises, async/await patterns, concurrency, and parallel data processing. • Experience building applications that support near real-time data delivery and dynamic user experiences. • Understanding of distributed systems and how front-end applications interact with microservices architectures. • Demonstrated ability to lead technical efforts and mentor junior engineers. • Bachelor's degree in Computer Science, Software Engineering, or related field; or graduation from an accredited coding bootcamp with equivalent experience. • Must possess or be willing to obtain a CompTIA Security+ certification. Preferred Qualifications • Experience with Svelte or other modern front-end frameworks. • Experience developing applications utilizing WebSockets and real-time communication technologies. • Familiarity with Kafka and event-driven architectures, including consuming and visualizing data originating from streaming platforms. • Experience supporting highly concurrent applications with complex data-loading requirements. • Experience with Kubernetes, Docker, and cloud-native deployment environments. • Experience delivering mission-critical applications within government, defense, intelligence, or other secure environments. • Experience designing front-end architectures for highly available and scalable systems. • Security+ certification. Clearance Level: TS/SCI with CI Polygraph • Position requires eligibility to access classified information and secure government facilities in support of program requirements. • Candidates selected for this position must be able to satisfy all government requirements for access to classified information associated with the program. • Experience working in classified environments and supporting mission-sensitive programs is highly desired. • Current TS/SCI eligibility and CI Polygraph are strongly preferred.","company":"Everforth","rawCompany":"everforth","city":"Denver","state":"CO","isRemote":false,"isActive":false,"createdAt":"2026-07-05T03:59:36.277Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1254.00","title":"Web Developers","slug":"web-developers"},{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"}],"industries":[{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"},{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"},{"code":"513210","title":"Software Publishers","slug":"software-publishers"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Front-End Developer with Security Clearance","description":"We are seeking an experienced Senior Front-End Software Developer who will be supporting the development of highly visible, mission-critical cloud-native applications that provide advanced Situational Awareness and Collaboration capabilities.
