About
Dear Hiring Team,
I am writing to express my interest in the Vehicle Physics / Unreal Engine 5 Developer position for the Formula Circus project.
I previously led the development of a commercial kart-racing game that operated for two years, where I was responsible for the full driving model, handling feel, stability logic, and long-term maintenance. This experience gave me practical, production-tested understanding of simcade-style vehicle handling, including:
Steering behaviour and input response
Tire friction and grip curves
Anti-flip and stabilization logic
Acceleration, deceleration, and speed curve design
Tuning for accessible, responsive driving feel
I am also currently developing a new Unreal-based kart project, which includes support for a simple, customizable track structure (using a light voxel-inspired approach). This work further strengthens my experience with modular systems and runtime level logic.
Additionally, I have ported my kart physics system to WASM and refactored parts of ODE (Open Dynamics Engine) during the process, giving me a solid understanding of rigid-body behaviour, constraint-driven systems, and joint-level control. This background allows me to quickly adapt to your R-Tune Physics System or to help build a modular vehicle physics framework within UE5.
I have strong experience with Unreal Engine 5 C++, Blueprint, Chaos physics, and plugin-based workflows, along with a solid engineering background in building scalable, high-performance systems.
Regarding availability:
I am currently completing a master’s degree in New Zealand and will graduate before August next year. During the academic period, I can reliably provide 20 hours per week of remote work. If needed, I can increase this to 25 hours per week through a visa variation (approx. USD $200 fee).
From mid-December to late January each year, I am available to work full-time.
Thank you for your time and consideration. I would be very happy to contribute to the vehicle physics and system development of Formula Circus, and I look forward to the opportunity to discuss further.
Kind regards,
WeiChen Liu
