Worldscape is looking for an experienced UI Engineer capable of thriving within a rapid development environment. You will be responsible for implementing and optimizing a high‑quality user interface for our next‑generation real‑time simulation platform and game engine. Partnering closely with UX designers and cross‑functional teams, you will translate finalized designs into scalable, performant, and maintainable UI code. Your role will focus on delivering precise, high‑fidelity implementations, ensuring responsiveness, usability, and seamless interaction with complex simulation and visualization systems.

This is an onsite role that will be located in Redmond, WA.

• Partner with UX/UI designers to implement and maintain robust, scalable user interface systems for our real‑time simulation platform, translating defined designs into production‑quality code.
• Develop and evolve high‑performance runtime UI architecture to support complex visualization, editing, and simulation workflows.
• Build high‑fidelity, responsive interfaces across desktop applications, in‑engine tooling, and runtime simulation products, ensuring accurate implementation of design specifications.
• Collaborate with UX designers, technical artists, graphics engineers, and product teams to translate approved concepts and requirements into reliable, production‑ready features.
• Design and implement reusable UI frameworks, components, and widget libraries to promote consistency, scalability, and efficient development across multiple products.
• Optimize UI systems for performance, including memory usage, rendering efficiency, and responsiveness in real‑time environments.
• Develop and maintain internal tools and pipelines that streamline UI implementation, improve developer workflows, and accelerate feature delivery.
• Integrate UI systems with core engine subsystems, including rendering, input, networking, AI, and simulation technologies.
• Contribute to engineering best practices, including code reviews, technical documentation, testing, and long‑term maintainability of UI systems.
• Help drive code quality and technical rigor across the team, including mentoring engineers and promoting scalable, maintainable implementation patterns.
• Deliver UI solutions that ensure reliable, performant user interaction with next‑generation simulation technology across commercial and defense applications.

• 6+ years of professional software engineering experience, with a focus on building UI systems for interactive or real‑time applications.
• Strong proficiency in C++, with experience building and shipping performant, production‑quality systems.
• Experience with Web Application industry standards:
  React, Type Script; architecting and implementing UI frameworks or systems, leveraging open‑source or proprietary technologies, with an emphasis on performance, scalability, and extensibility in games, engines, or simulation platforms.
• Experience developing production‑quality UI implementations using modern frameworks such as Dear ImGui, Unreal UMG/Slate, Unity UI Toolkit, Qt, Coherent, NoesisGUI, or similar technologies.
• Strong understanding of software architecture, object‑oriented design, and component‑based UI patterns, with the ability to build maintainable and extensible systems.
• Experience building and maintaining reusable UI frameworks, component libraries, and shared tooling, rather than one‑off interfaces.
• Solid understanding of event‑driven programming, input systems, state management, animation…
