This high-impact role offers significant ownership and the opportunity to define the technical frontier of AI-driven game development alongside a world-class team.

The ideal candidate:

• Professional experience building production-ready agentic systems and pushing the frontier of LLM performance.

• Strong software engineering foundations in Python with a focus on testing, version control, and scalable architecture.

• A self-starting, hungry individual comfortable with the high-responsibility and long-hours environment of a founding team.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
