Job Title: Founding Game Designer


Salary: £80k–110k + Equity


Company Description: Pebble – VC-backed generative AI startup


Job Description:

As the first Game Designer at Pebble, you will define the mechanics of a generative learning world for children aged 6–10. You will design the systems, constraints, and voice-driven progression for a procedural environment in Godot 4. This role bridges game design, child development, and AI to create meaningful, adaptive play.


Location: London, UK


Why this role is remarkable:

  • Join a founding team led by former Google and Synthesia leaders who scaled a startup from $3M to $100M ARR.
  • Build the first "generative learning world," a new genre inspired by The Diamond Age where the narrative and world adapt in real-time.
  • Massive ownership as the first design hire with significant equity in a high-growth startup backed by top-tier US investors.


What you will do:

  • Design the exploration systems, pacing, and progression mechanics that drive engagement through genuine curiosity rather than dark patterns.
  • Use AI tools and LLMs to prototype text, image, and voice-driven interactions within a Godot 4 development environment.
  • Define the visual identity and art direction for a procedurally generated 2D world and its central AI companion characters.


The ideal candidate:

  • Has shipped at least one game or interactive product where they owned core systems design, progression, and player economy.
  • Demonstrates strong systems thinking, with a portfolio showing how they design rules for emergent behavior rather than fixed content.
  • Is a creative generalist comfortable with Godot and prototyping quickly for a young audience of children aged 6–10.

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.
