R&D PROGRAMMER | RPG game title production company

Hiring Company tri-Ace Inc.
Location Tokyo - 23 Wards, Minato-ku
Job Type Permanent Full-time
Salary 3.5 million yen ~ 5 million yen

Job Description

Scope of Work
tri-Ace Research & Development Department (R&D) is working on the construction of a next-generation game development framework that goes beyond the conventional game engine concept. For example, this framework aims to realize real-time inference processing (millisecond level) of neural network (NN) models in games. Therefore, we are looking for engineers in a wide range of fields, from real-time inference implementation of NN models to the development of machine learning models.
*The expression “AI” in this application guideline does not refer to conventional game AI, but to AI using NN model-based machine learning.

We are looking for the following people:

1. Those who are interested in real-time inference and optimization, and want to apply them to game development.
Engineers who would like to challenge the technology to realize real-time AI inference processing in games. We welcome those who are interested in high-speed inference processing at the millisecond level executed in every frame of a game, verification of inference accuracy, and construction of a test environment to maintain performance.
For example, even if you are not familiar with AI development, we also welcome those with strengths in GPU optimization (shaders, memory access bandwidth, etc.).

2. Machine learning engineers who want to take on the challenge of game engine optimization and AI applications.
Those who would like to take advantage of their experience in developing machine learning models and tools to work in new areas of game development. We welcome those who would like to challenge fields such as real-time inference and optimization in the future.

3. Those who would like to challenge a career as a machine learning engineer by utilizing their game development experience.
Those who have experience in game development in C++, are interested in machine learning, and want to build up their skills as a machine learning engineer in the future. We welcome those who want to learn new knowledge and take on the challenge of developing AI-based game frameworks.
