How we know
It hasn't been reposted, listed twice, or left up unusually long, and the posting doesn't say it's a talent pool.
Ghostless records the day it first sees a posting, so a repost can't reset its age. This one was already up when Ghostless started tracking Spellbrush, so its true age is longer.

Ontario requires postings from employers with 25 or more staff to state the pay, whether the vacancy exists, and whether AI screens applicants.
Some employers add pay only on their own site. Check the original posting before you rule it out.

About the role
We’re looking for an experienced HPC infrastructure engineer to lead bringup, administration, and operations on is probably the largest anime AI training cluster in the world . You’ll serve as the bridge between our researchers and the bare GPU machines, helping to make sure that SLURM jobs are running, parallel filesystems are serving, network is transmitting, and that the anime models are training.
You may be a good fit if
You love anime and the anime aesthetic.
This probably one of the only jobs in the world where you will get to combine your love of anime and large-scale GPU systems.
You’re familiar with the modern HPC software landscape
Once upon a time, our team could install SLURM on a few bare metal nodes and get away with it. Now the landscape has become unbelievable complex, with SLURM deploys through Slinky on K8s, provisioning through warewulf/MAAS/ansible, filesystems through WEKA/VAST/Ceph, VPN and access through tailscale, and monitoring via the Grafana/Prometheus stack. We’re looking for someone with relevant experience up and down the stack (and maybe a papercut or two to show for it!)
As well as the traditional sysadmin landscape
Bringing up and managing cluster still requires good old linux sysadmin skills, including wrangling ldap, triaging dmesg, and setting sticky bits on directories for misbehaving users and tools.
You're not afraid of physical computers
We’re building out edge datacenters and our CEO is still personally racking, stacking, and provisioning HGX-based nodes in our living room. Also his VLAN design sucks and he’s bad at fiber routing. Please send help.
And you're comfortable working on small, fast-paced teams.
We currently have a very tiny research team, and you’ll be directly helping some of the AI researchers in the world train the best anime image model in the world.
We also believe in the unmatched speed of in-person teams, and prefer on-site collaboration in either our primary research office in Tokyo (downtown Akihabara), or San Francisco (dogpatch!). Bay area is strongly preferred as we have physical hardware in the Bay Area. Visa sponsorships are available.
