About The Position

Worldscape is a cutting-edge platform designed to unify distributed data, sensors, and intelligent agents across cloud, on-prem, and edge environments. By combining geospatial intelligence, physics-based 3D simulation, and reward-driven AI, Worldscape enables organizations to build immersive digital twins for predictive modeling, scenario planning, and adaptive decision-making. With a zero-trust security framework, seamless integration with legacy systems, and robust developer tools, Worldscape empowers rapid deployment of agentic applications that drive resilience and efficiency in sectors like logistics, telecom, defense, and infrastructure. 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.

Requirements

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.
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.
