About Joseph R. Jones (JRJ)

“Scruffy-looking nerd herder (semi-retired) and world’s foremost expert in self-proclaimed thought leadership. Owner, Rimrock Systems”

These days I’m mostly working on apps for Apple Vision Pro, Mac, and iOS shipping as Rimrock Systems. My wife says I’m “in my Victorian Gentleman-Scientist Era” 1 and if that means I get to tinker with what I want to tinker with that suits me just fine.

Back Story

Before Semi-retirement and Rimrock, in reverse-chronological order:

  • Director of Software Engineering at The Walt Disney Company focused on native players in Rust and C++ for the streaming side until I retired in October 2025
  • Founded Virtual Neural in 2020 to explore the intersection of spatial computing and artificial intelligence (being early is the same as being wrong.)
  • A decade (to the day) at Adobe as the Group Product Manager on the Experience Cloud’s identity system and Principal Product Manager on Adobe Primetime Video.
  • 5 years (precisely) at Microsoft in the late 2000s working on Media Foundation, Zune, and Xbox.
  • A decade of startups and early internet companies going back to the early 90s when I was co-webmaster at a community college.

After 30+ years of going where my job was, Rachel and I finally settled down in Arizona rim country. When I was a kid I told myself I was going to retire in Payson because that’s where all our best camping and boy scout trips began. 50 years later, here I am, seeing if I can manage to hit every trail in the area before I die (spoiler alert: probably not unless the more utopian longevity estimates come true.)

Contacting JRJ

The door is more open than it used to be. Anything about a Rimrock app goes to [email protected] or @rimrock-systems on Twitter/X where it’s read by a human 3 with more channels coming soon. Beyond that:

  • GitHub is where work lives, but most not yet open source
  • LinkedIn, though connections stay people I actually know
  • @jrj on X, starting to open up a bit more

Colophon

Static origin via Jekyll as before, but more minimalist Chirpy theme (with minor tweaks.)

  1. The reference was intentional if aspirational, I married well. John Carmack of Doom–>Quake–>Oculus fame (and arguably the most brilliant programmer of my generation) famously said he was was retiring to work on AI “Victorian Gentleman-Scientist Style” and Rachel and I thought it was a rich metaphor at the time. ↩

  2. The Halcyon was the flagship of the Chandrila line. The Star Wars: Galactic Star Cruiser announced it was closing literally as Rachel and I were driving home from our first visit. I consider myself lucky I got to go a second time with my nieces and nephew. I got to spend a week living in Star Wars. I continue to think it’s the most magical thing Disney has ever done. ↩

  3. The human is me at the moment. ↩
