About The Position

Defense Unicorns is seeking a Senior Full-Stack Engineer to join our Fleet team, focused on building and evolving Fleet Management and Edge Management capabilities within the UDS platform. This role is centered on developing complex, data-driven interfaces that allow users to understand, manage, and operate distributed systems across edge and remote environments. These are not simple CRUD interfaces—they are operational control surfaces for real-world systems. You will own and drive the frontend experience, while working across the stack to ensure tight alignment between UI behavior, APIs, and underlying system capabilities. You’ll collaborate closely with backend engineers, platform engineers, and designers to build responsive, reliable, and intuitive experiences on top of complex APIs and distributed system state. While frontend-focused, this role requires strong full-stack awareness—understanding how data flows through systems, how APIs are designed, and how frontend decisions impact system behavior, especially in asynchronous and distributed environments.

Requirements

5+ years of experience in frontend or fullstack development
Strong proficiency with modern frontend frameworks (Svelte or React preferred; Angular or similar frameworks acceptable)
Strong familiarity with modern frontend tooling and build system best practices
Experience with testing strategies across frontend applications
Experience building data-intensive or state-heavy applications
Strong understanding of API design and integration (REST, GraphQL, etc.)
Experience working closely with backend systems and distributed architectures
Strong problem-solving skills and ability to navigate complex systems
Excellent communication and collaboration skills
