About the Role: Red Hat's DNS and Operating Systems (D/OS) team owns the foundational infrastructure layer the entire company runs on: DNS, Linux and Windows OS platforms, full-disk encryption, and access and bastion services. We serve everyone from engineering labs to global business operations, and we care about operational excellence, clean automation, and systems that work without heroics. Red Hat is an open source company, and that shapes how we operate - decisions happen in the open, knowledge is shared, and the strongest technical argument wins regardless of title. We are looking for a Principal Information Systems Engineer who has gone deep in infrastructure and is now as comfortable setting direction as executing it. You will drive how our services evolve, work with team leadership to establish the technical standards the team works to, and serve as a credible technical voice with adjacent teams. The team will bring you up to speed on D/OS-specific tooling and institutional knowledge. What we need from you is the experience and ownership mindset to take real technical authority, ramp quickly, and help us improve our portfolio of offerings. What You Will Do Partner with IT leadership and adjacent IT teams as the D/OS technical authority on shared infrastructure concerns. Own major services across the portfolio (DNS, Linux platform, automation, access services) and drive architectural decisions with documented trade-offs. Lead infrastructure changes from scoping through delivery, whether upgrades, migrations, or re-architecture. Define SLOs, close systemic reliability gaps, and lead post-mortems that produce durable fixes. Join the team's global on-call rotation as you ramp in; be a stabilizing presence during incidents. Grow senior engineers through design review, mentorship, and hands-on guidance; document decisions and operational knowledge to outlast any individual. What You Will Bring Leadership & Mentorship: Demonstrated success grow .

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
