Senior Unreal Engine Developer

**About Us:** Ctruh is a deep-tech company building the infrastructure layer for the spatial internet through a proprietary browser-native, no-code 3D engine and VersaAI, our in-house generative AI engine that transforms text, images, and video into production-ready 3D assets in minutes. **Our Work Rhythm:** This is a 6-day working setup with Monday to Friday operating from office and Saturday as Work From Home (WFH). We believe this model enables stronger collaboration, faster learning, and better team alignment while maintaining flexibility. **About the Role:** We're looking for an experienced Senior Unreal Developer to lead the development of next-generation Digital Twin solutions for Real Estate, Architecture, Automotive, and Smart Infrastructure. You'll build immersive, data-driven, real-time 3D applications that combine Unreal Engine, live data streams, BIM/CAD models, and interactive visualization to enable intelligent decision-making. This role is ideal for someone who enjoys solving complex technical challenges, architecting scalable systems, and building high-performance real-time applications. You'll work closely with Product, Engineering, Design, AI, and client teams while driving the technical direction of Ctruh's Digital Twin platform. **What You'll Own:** * Lead the design and development of large-scale Digital Twin applications using Unreal Engine 5. * Build interactive, real-time 3D environments that integrate live data from APIs, IoT devices, telemetry systems, and enterprise platforms. * Design scalable Digital Twin architectures that support real-time monitoring, analytics, simulations, and operational decision-making. * Develop advanced data visualization experiences including dashboards, heatmaps, overlays, X-ray views, and interactive analytics within immersive 3D environments. * Build intuitive user interactions that simplify complex datasets and improve stakeholder usability. * Leverage Unreal Engine 5 features including Lumen, Nanite, and modern rendering pipelines to deliver photorealistic visual experiences. * Optimize rendering performance, memory utilization, scalability, and runtime efficiency across large and complex 3D environments. * Build and maintain BIM/CAD integration pipelines using Revit, Rhino, Datasmith, and related workflows while preserving geometry, metadata, and model accuracy. * Collaborate with Architecture, Engineering, Product, and AI teams to ensure seamless data integration and technical alignment. * Deploy Unreal applications using Pixel Streaming to deliver browser-based Digital Twin experiences with low latency and high scalability. * Lead technical architecture decisions, establish Unreal development best practices, and mentor engineering teams. * Continuously improve system performance, development workflows, and platform scalability while staying current with the latest Unreal Engine advancements. **What You Bring:** **Must-Haves:** * 5+ years of professional experience developing applications with Unreal Engine. * Strong portfolio showcasing Digital Twins, Architectural Visualization (ArchViz), Automotive Visualization, or real-time interactive 3D applications. * Proven experience integrating Unreal Engine with external data sources such as REST APIs, JSON, MQTT, WebSockets, or similar technologies. * Strong expertise in Blueprints, Unreal rendering pipelines, gameplay systems, and interactive application development. * Experience building and optimizing large-scale real-time 3D environments. * Strong understanding of rendering optimization, memory management, and performance tuning. * Experience working with Unreal Engine 5, including Lumen and Nanite. * Excellent problem-solving skills with strong architectural and system design capabilities. * Comfortable working in fast-paced, product-driven startup environments. **Good-to-Have:** * Experience with Cesium for Unreal, ArcGIS, GIS, or geospatial visualization platforms. * Strong technical art knowledge including shaders, material systems, lighting, and rendering optimization. * Experience with BIM workflows using Revit, Rhino, Datasmith, or related architectural tools. * Familiarity with Pixel Streaming, cloud deployment, and browser-based Unreal applications. * Experience developing Digital Twin platforms for Real Estate, Manufacturing, Automotive, or Smart Cities. * Leadership experience mentoring engineers and driving technical decision-making. * Exposure to AI-powered visualization, simulation systems, or immersive technology platforms. **What Success Looks Like:** Success in this role will be measured by delivering scalable, high-performance Digital Twin applications, enabling seamless real-time data integration, building immersive visualization experiences, maintaining exceptional rendering quality while optimizing performance, improving platform scalability, and earning strong feedback from clients, Engineering, Product, and Leadership teams. **Why Join Ctruh:** At Ctruh, you'll work on cutting-edge Digital Twin platforms that combine AI, real-time visualization, immersive technologies, and browser-native 3D experiences. You'll help shape the technical architecture of products used across Real Estate, Automotive, Manufacturing, and Smart Infrastructure while collaborating directly with leadership and influencing the future direction of the platform. This is a high-impact role offering significant ownership, technical leadership, and the opportunity to solve complex engineering challenges while building next-generation immersive technology products. **Who Will Thrive Here:** You are a technically strong, systems-oriented engineer who enjoys building large-scale real-time applications that combine visual excellence with engineering precision. You thrive on solving complex architectural challenges, integrating live data into immersive experiences, and creating scalable systems that deliver measurable business value. You take ownership, mentor others, embrace technical excellence, and are excited about pushing the boundaries of Digital Twins, Unreal Engine, and real-time visualization in a fast-paced deep-tech startup.
