Cesium, WebGL/Three.js), and enough familiarity with the developer toolchain (Git, browser dev tools) to collaborate and hand off cleanly [AI can generate screens all day long, but you're the one who has to make them beautiful, coherent, and loved by the people who use them]Demonstrated ability to design and implement natural language interfaces, including conversational interactions, agentic workflows, and experiences where AI is a critical part of the UI/UX itself, not just the process that built it [Show us an interface where AI made the product better, not just the demo flashier]Exceptional aptitude for building tangible products [Must be able to demonstrate this by a portfolio of shipped interfaces, design systems, or serious side projects]Strong intellectual curiosity [You will be asked to leave your comfort zone early and often, so we're looking for evidence that you've done this on your own before]Preference for self-directed work [You'll work with our top technical talent, but we're looking for evidence that when given a problem to solve, you know how to identify and execute the means for solving it.]Demonstrated history of effective collaboration [You'll be working with multiple other people as part of a variety of integrated teams and must be capable of both shouldering work yourself and leading projects with little guidance. This implies other things like good communication, planning and coordination, and 'soft' skills.]Demonstrated ability to engage customers directly to deeply understand their needs [You'll interact with many stakeholders, from engineers to analysts, operators to program managers, and the best design decisions come from understanding what each of them actually needs, not just what they say they want]Other qualifications we hope you bring to the table:Experience building interfaces for simulations, numerical software, or other data-dense engineering tools [If you've made a complex dataset effortless to explore or turned an engineer-only tool into something anyone can drive, we want to hear about it!]Experience working in a startup environmentFamiliarity with DoD modeling & simulation verification, validation, and accreditation (VV&A) processesA background in physics, electrical engineering, or modeling & simulation [Our sim models real-world phenomena, and domain intuition makes you a better builder of it]Other specifics about this position:Contingent upon contract award?
