Senior Full-Stack UI Engineer (remote/onsite)

📍 Job Overview

Job Title: Senior Full-Stack UI Engineer Company: BeamNG GmbH Location: Bremen, Bremen, Germany (Remote/On-site flexibility) Job Type: Full-Time Category: Software Engineering / UI Development Date Posted: January 30, 2026 Experience Level: Senior (5-10 years implied) Remote Status: Remote OK (with on-site option)

🚀 Role Summary

• Drive the end-to-end development of in-game user interfaces using Vue 3 and JavaScript, focusing on real-time data rendering and user intent forwarding.
• Optimize UI performance and stability to achieve a consistent 60 FPS feel and ensure leak-free, long-running sessions within a demanding game engine environment.
• Collaborate closely with Lua specialists to define clear UI-to-engine contracts, ensuring business logic remains within the Lua backend.
• Implement robust navigation and input handling systems, prioritizing gamepad and keyboard-first experiences for a broad user base.
• Enhance the overall developer experience through practical tooling improvements, debugging aids, and performance instrumentation.

📝 Enhancement Note: While the title is "Senior Full-Stack UI Engineer," the description emphasizes a strong focus on UI development with a "backend" being Lua. The "full-stack" aspect appears to refer to the ability to handle UI implementation, data contracts, and basic integration glue code, rather than traditional web backend development. The role requires a deep understanding of browser rendering and JavaScript runtime, suggesting a strong focus on the client-side of the UI.

📈 Primary Responsibilities

• Build and implement Vue 3 Single File Components (SFCs) using the Composition API, integrating with SCSS for styling.
• Define and maintain clean contracts between the JavaScript UI layer and the Lua game engine for seamless data exchange and event handling.
• Develop UI features that remain highly responsive and stable while processing discrete events and high-frequency data streams (telemetry).
• Implement and refine scoped navigation and input systems, ensuring correct behavior with gamepad and keyboard inputs, and managing input propagation.
• Profile, diagnose, and optimize rendering, layout, and update frequencies to meet stringent performance targets, aiming for a fluid 60 FPS experience.
• Collaborate with Lua specialists to ensure business logic and data conversions reside within the Lua backend, keeping the Vue frontend focused on presentation and state management.
• Contribute to the improvement of development workflows, tooling, debugging capabilities, and performance instrumentation for the UI team.
• Provide code reviews, offer mentorship to junior engineers, and uphold high-quality standards without unnecessary complexity.

📝 Enhancement Note: The responsibilities highlight a "Lua-first" architecture, where the UI's primary role is rendering and forwarding user intent. This implies that the engineer must be comfortable working within these constraints and collaborating closely with engine/gameplay programmers. The emphasis on performance and stability for long-running sessions is critical for a game engine UI.
