Job Description:

We are focused on creating a state-of-the-art, real-time, soft-body physics engine and making it widely available for entertainment and simulation purposes. Our most widely known product is our game BeamNG.drive, which is now available on Steam in Early Access. In order to support our ongoing and future development plans, we are seeking an experienced Senior Full-Stack UI Engineer with a focus on Vue3 and Lua for our development team, who will support us in finishing the game.

Job Responsibility:

  • Build UI features end-to-end: implement Vue UI, define clean UI↔Lua contracts, and collaborate with Lua specialists (you can handle basic Lua glue when needed)
  • Make UI fast and stable: profile and optimize rendering/layout/update frequency to reach a 60 FPS feel where it matters, and keep long-running sessions leak-free
  • Keep business logic in Lua: keep Vue focused on presentation and simple UI state
  • avoid moving backend logic/data conversions into JS
  • Work with real-time data: design UI that stays responsive while receiving frequent updates from the game/simulation
  • Own navigation/input correctness: integrate scoped navigation and UI event handling so screens behave correctly with gamepad/keyboard and don’t leak inputs to parent scopes
  • Improve developer experience: small, practical improvements to tooling/pipelines, debugging helpers, and performance instrumentation
  • Support the team: review code, help juniors grow, and keep quality high without over-engineering

Requirements:

  • Deep web fundamentals: strong understanding of browser rendering (layout/paint/compositing), the JS runtime (event loop, GC), and how to diagnose performance issues with real tools (performance + memory profiling)
  • Proven performance experience: you’ve shipped UI where performance mattered (large UI surface, frequent updates, long-running sessions) and can explain the trade-offs you made
  • Strong

Nice to have:

  • Experience with embedded browser UIs / game UIs / realtime dashboards / telemetry-heavy UIs
  • Knowledge of input systems
  • Familiarity with C/C++ or engine integration concepts (even if you don’t write engine code daily)
  • Experience migrating legacy UI systems incrementally (keeping features shipping while modernizing)
  • Experience setting up practical UI testing/automation (wishlist for us
  • currently mostly manual)
What we offer:
  • Flexible working hours
  • Language courses
  • Talent development program (training budget, participation in seminars/conferences, and etc)
  • Personal development program (feedback, leadership, conflict engagement, etc)
  • Budget for home office
  • Parental leave
  • Employee assistance program
  • Relocation assistance (if applicable)
