- 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.

- 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 withSvelte or other modern front-end frameworks.
- Experience developing applications utilizingWebSockets and real-time communication technologies.
- Familiarity withKafka 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.
