ABOUT
Real job market data, analyzed quarterly, to help you make informed career decisions.
LinuxCareer.com exists because career decisions deserve real data, not blog opinions, recruiter hype, or gated whitepapers.
Whether choosing a certification, learning a new skill, or negotiating a salary, the data here comes from what employers are actually asking for.
In the spirit of free software, the data is published under a Creative Commons license -- free to use, share, and build on with attribution. No paywalls, no gated reports, no "sign up to download."
The methodology is documented. Every number comes from real job postings. If something looks off, it can be questioned and corrected.
No sponsored content, no affiliate deals, no guest posts pushing products. Editorial independence is not negotiable.
LinuxCareer.com started in 2013 as a collaboration between myself and Brent Marinaccio of HotLinuxJobs.com. The idea was simple: help Linux professionals navigate their careers with better information.
Life got in the way and the project went quiet. But the need didn't go away. If anything, the Linux job market became more complex. More skills, more certifications, more specialization paths, and less clarity about what actually matters.
In 2025, I picked the project back up with a different approach. Instead of opinions and guesswork, I built a data pipeline that scrapes real job postings from LinuxCareers.com, a job portal I also maintain, and extracts skills, certifications, and salary data. The result is quarterly reports based on what employers are actually asking for, not what someone thinks they should.
It's currently a one-person project, but always open to working with partners and collaborators who want to help make the data better. The tradeoff is speed, but what you get is honest data, no filler, and no sponsored content.
Founder
GNU/Linux system administrator and FLOSS advocate since 2000. Runs LinuxConfig.org (3,000+ articles), LinuxCareers.com (job portal), and this site. All three operated by TOSID GROUP PTY LTD, an Australian company.
Every number on this site comes from real job postings. Here's the process:
Job postings are ingested from LinuxCareers.com, a dedicated Linux job portal. Thousands of postings are processed each quarter.
Each posting is analyzed to extract skills, certifications, salary ranges, seniority levels, and location data. Skills and certifications are tracked separately because they're different things, and the data reflects that.
The raw data is queried for rankings, co-occurrence patterns, lift scores, salary distributions, and quarter-over-quarter trends. Generic skills like "Linux" and "Windows" are excluded from rankings on a Linux-focused board because they'd appear in nearly every job and distort the signal.
Reports are published quarterly. Each update includes skills, certifications, and salary data for the period. The numbers are cumulative, with every quarter adding to the dataset.
Thanks to Brent Marinaccio and HotLinuxJobs.com for the original collaboration that got LinuxCareer started in 2013. The project wouldn't exist without that foundation.
Found something off in the data? Have a suggestion? I'm always happy to hear from people who use the site.
