Senior UI Engineer

About the role

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.

Responsibilities

• 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

Professional Qualifications

• 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, TypeScript
• Experience 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 systems, and responsive layout implementation
• Experience profiling, debugging, and optimizing UI performance in real-time or resource-constrained environments
• Strong debugging, problem-solving, and systems-level thinking skills
• Experience working in cross-functional teams, effectively collaborating with UX designers, artists, and engineers to translate specifications into working systems
• Experience shipping at least one commercial game, simulation product, or interactive application

Preferred Qualifications

• Professional game development experience
• Experience developing editor tooling or in-engine development tools
• Experience building interfaces for simulation, digital twins, GIS, robotics, defense, aerospace, or visualization platforms
• Knowledge of modern rendering pipelines and how UI integrates with real-time graphics systems
• Experience working with ECS architectures and data-driven UI systems
• Experience with GPU-aware UI rendering and performance optimization
• Experience implementing data visualization, dashboards, graphs, timelines, or large-scale monitoring interfaces
• Understanding of multiplayer or networked UI synchronization
• Experience working alongside AI/ML teams or visualization systems
• Experience mentoring engineers and helping define engineering best practices
• Passion for building polished, intuitive user experiences that simplify highly technical workflows

Benefits

• Competitive salary and meaningful equity
• Attractive benefits package
• Flexible time off policy
• Medical, Dental and Vision insurance
• HSA health insurance options
• 401k plan
• Basic and Voluntary Life Insurance
• Fast paced environment with flexibility and ownership
