- What we charge
- What others say
We are currently looking for technical consultants for remote and on-site professional services. Up for the challenge? Read on.
What we require (hard qualifications)
What follows is a list of things we really require of people applying for the position. If you meet all of these criteria, please talk to us!
- have a strong Linux sysadmin and operations background. Having worked full-time on Linux systems for 5 years or more is ideal.
- be comfortable interacting with customers on a daily basis, in person, on the phone, and via text, voice and video chat.
- speak and write English to a degree that allows you to both communicate on technical matters, and convey your personal views, thoughts and ideas.
- be comfortable with working from home, in a distributed team whose members you very infrequently meet in person. Please note that this also includes that the people you live with (such as your immediate family) need to be comfortable with this.
What we're also looking for (additional qualifications)
If any of the following apply to you in addition to the above, we definitely would like to talk to you. These are, however, not required, and they are listed here in no particular order of importance.
- You have experience working with the Linux high-availability cluster stack, distributed storage systems like GlusterFS and/or Ceph, or OpenStack.
- You have previously worked as a technical consultant or training instructor (and enjoyed the experience).
- You speak and write Spanish, Mandarin Chinese, French, and/or Russian (in addition to English).
- You have previously worked (full or part time) as a technical writer, documentation specialist, or technical journalist.
- You are a United States citizen or resident, hold a valid Business Visit (B-1 or B-2) visa for the United States, or are able to travel to the United States for business visits under the U.S. visa waiver program.
What will get us even more interested (soft skills)
We're looking for people with a strong sense of responsibility, autonomy, and cultural awareness. We won't ask you about any of the following, but we would be grateful if you told us in case
- you're a parent,
- you have served or are serving in the military, a caregiving organization, a volunteer fire brigade, medical or ambulance service, or the like,
- you've been exposed to multiple cultures and regions by living and/or working there.
What we don't care about
In this century this should go without saying, but we'll still stress the point: if you match the type of skill set we're looking for, we would love to talk to you regardless of
- your gender or gender identity,
- your sexual orientation,
- your religious affiliation,
- your ethnic background.
That doesn't mean we can't talk about it (please share as much about yourself as you're comfortable with!), just that it won't influence our appraisal of your skill set and personality.
Interested? Please let us know!
Getting in touch is real easy. Just drop us a line! We're looking forward to hearing from you.
