Senior UI/UX Software Engineer

Bluestaq US External•Colorado Springs, CO

About The Position

Bluestaq is seeking a Senior UI/UX Software Engineer to design, build, and maintain intuitive, accessible, and high-performance user interfaces for mission-critical government and commercial systems. In this role, you will own significant UI features and user workflows end-to-end—spanning frontend implementation, API integration, and data interaction—while leading design execution from concept through production. You will combine strong frontend engineering expertise with user-centered design thinking to deliver interfaces that operate reliably under real-world operational constraints, including high-stakes, low-latency, and degraded network environments. Why This Role Matters Senior UI/UX Software Engineers serve as the bridge between user needs and technical implementation. Your work directly shapes how operators, analysts, and mission users interact with complex data and systems on a daily basis. From space domain awareness platforms to defense health systems, you will ensure our software is not only functional—but usable, accessible, and resilient when it matters most. This role offers the opportunity to influence UI architecture and design patterns, mentor other engineers, improve long-term maintainability of frontend systems, and solve meaningful problems in a mission-driven environment.
