Why join

Why OpenBoxAI

01

A global player base

Our games are live in more than 40 countries and regions, and the effect of each update can be verified in next-day retention and conversion data.

02

Sustained tech investment

The Character Memory System, Procedural Content Generation and the engine toolchain each have a dedicated R&D roadmap and compute budget.

03

Small, end-to-end teams

Each project team has 5–8 people, with design, engineering and art working side by side for short decision paths and fast iteration.

04

A sustainable pace

Time off in lieu follows every crunch period, so long stretches of overwork never compromise content quality or team stability.

05

Clear career growth

Dual technical and management tracks with reviews every six months. Books, courses and industry conference travel are reimbursed.

06

Local roles, global projects

Work on games and technology research for overseas markets without relocating to a tier-one city.
