About us
We were tired of courses that assumed we knew nothing
Atrium started as an internal training programme for a platform team that could not find anything at the right level.
Origin
The intermediate gap
There is an enormous amount of material for absolute beginners and a reasonable amount of conference talks for experts. For the engineer with four years of experience who needs to actually operate something, there was almost nothing. That gap is the whole catalogue.
- Courses are re-recorded rather than patched
- Everything downloadable at full quality
- Pass rates published, because a meaningless certificate helps nobody

How we work
Boring on purpose
We would rather run software that is three years old and understood than something new that pages us at 04:00.
Own the path
We buy transit from multiple carriers and peer directly wherever it is possible, so a single bad hop is never a single point of failure.
Write it down
Every incident gets a public write-up. Every design decision gets an RFC. Institutional memory beats heroics.
Some of the people behind it
A quarter of the company has been here since the first rack.
We are hiring
Remote-first across EU time zones, with a small office network for people who prefer one.
