Sean Yo +ai Application · Director of Product, Gaming New Products

What will Mozilla contribute to gaming that would be different because Mozilla built it?

I’m Sean Yo, and I’m applying for Director of Product, Gaming (New Products) at Mozilla. This is exactly the kind of problem I want to spend the next few years thinking about and building around. Below are a few things I’ve made, led, written and explored that show how I might contribute, starting with a production web game you can play right now.

Campus RPG

Playable · in your browser · no install

A JRPG-style exploration of three real college campuses, built so new and international students could learn a place — and how to live in a new country — through exploration and quests instead of an orientation slideshow. You play as Condor, the college mascot. I led product and game design, and ran the transdisciplinary team from definition through delivery.

It ships in a browser, on the open web, for an audience that mostly didn't identify as gamers. That combination is roughly the thing I'd want to be doing at Mozilla.

Campus RPG: a student's dorm room in top-down pixel art, with Condor the mascot saying "It's the first day of school, today."
The opening beat: you play as Condor, in your room, on your first day.

MadCap Adventures

Demo reel · 2 min

Educational video games I led game and interaction design for — a platform funded by the Bill & Melinda Gates Foundation and Pearson Education, developed alongside Sir Ken Robinson, Peter Senge and Michael Fullan. Learning objectives built into gameplay rather than bolted onto it.

Mozilla isn't new to me

I've been working on open, participatory technology for about as long as I've been working.

  • Helped found Hive Waterloo in 2012; it became an official Mozilla Hive Learning Community in 2015 and operated through 2018, with early programming at Communitech.
  • Co-founded and chaired the IMS Global Privacy Task Force, and contributed to the LTI, Caliper Analytics and Accessibility working groups — open standards, written in committee, shipped in products.
  • Years of accessibility work and advocacy, including talks at ConFoo, WordCamp Toronto and Seneca's open-source symposium, plus a closing keynote on programming as a 21st-century literacy.
  • Co-founded Year of Code Waterloo Region; co-editor of Code Like A Girl as it grew toward 40,000 readers. In 2007, three weeks in Nepal helping member organizations of Fair Trade Group Nepal build their own web capacity.

Where the +ai in my name comes from — AI as a collaborator, with judgment and accountability staying human.
How I keep a product organization pointed at one thing when three functions each want their own roadmap.
On emotionally safe leadership, and what it actually costs to build teams that do original work.
Momentum, mass and why some pivots are cheap and others quietly aren’t.
