User Experience Designer

Are you ready to make a significant impact by supporting critical national security infrastructure? T-Rex Solutions is looking for a fully cleared User Experience Designer 2 to join our dynamic team de, MD in support of the Intelligence Community.

• Support the UX Lead by conducting user research sessions (interviews, usability tests, contextual inquiries) to collect raw behavioral and attitudinal data.
• Execute discussion guides, screeners, and research protocols as defined by the UX Lead.
• Observe and document user behaviors, pain points, and patterns during sessions, distinguishing what users say from what they actually do or need.
• Administer quantitative data collection methods (surveys, card sorting, tree testing) in support of research plans set by the UX Lead.
• Compile and organize raw research data (notes, session artifacts) into clean, structured formats for UX lead to synthesize.

• Hands‑on experience conducting usability testing, interviews, and/or contextual inquiry directly with end users.
• Comfortable assisting research sessions alongside a UX lead. Experience independently running research studies end‑to‑end (objective‑setting, study design, execution, and synthesis) is a plus.
• Working knowledge of both qualitative discovery methods (usability testing, contextual inquiry) and quantitative data collection methods (surveys, analytics review, A/B testing, card sorting, tree testing, session observation). Demonstrated experience is a plus.
• Strong note‑taking and data organization skills where they are able to capture and structure raw findings accurately for leadership synthesis and analysis.
• Reliable, detail‑oriented execution of research protocols with minimal need for independent research strategy or stakeholder presentation.
• Comfort operating with ambiguous, evolving requirements typical of mission/IC environments that is able to define research questions when none is handed to them is a plus.

• Analyze user requirements to derive software design and performance requirements
• Debug existing software and correct defects
• Provide recommendations for improving documentation and software development process standards
• Design and code new software or modify existing software to add new features
• Integrate existing software into new or modified systems or operating environments
• Develop simple data queries for existing or proposed databases or data repositories
• Write or review software and system documentation
• Serve as team lead at the level appropriate to the software development process being used on any particular project
• Design or implement complex database or data repository interfaces/queries
• Develop or implement algorithms to meet or exceed system performance and functional standards
• Assist with developing and executing test procedures for software components
• Develop software solutions by analyzing system performance standards, confer with users or system engineers; analyze systems flow, data usage and work processes; and investigate problem areas
• Modify existing software to correct errors, to adapt to new hardware, or to improve its performance
• Design, develop and modify software systems, using scientific analysis and mathematical models to predict and measure outcome and consequences of design
• Design or implement complex algorithms requiring adherence to strict timing, system resource, or interface constraints;
  Perform quality control on team products
• Implement recommendations for improving documentation and software development process standards
• Oversee one or more software development teams and ensure the work is completed in accordance with the constraints of the software development process being used on any particular project
• Confer with system engineers and hardware engineers to derive software requirements and to obtain information on project limitations and capabilities, performance requirements and interfaces
• Coordinate software system installation and monitor equipment functioning to ensure operational specifications are met
• Recommend new technologies and processes for complex software projects
• Serve as the technical lead of multiple software…
