What you will do OpenBlue from Johnson Controls is a cyber-secured smart building ecosystem that unifies data, AI, and automation to transform how buildings perform. By connecting systems that have historically stood apart and applying award-winning analytics, we give customers real-time visibility, predictive insight, and automated action across the entire building lifecycle. None of that reaches a customer without the platform underneath it. Our data platform, our enterprise SaaS portfolio, and OpenBlue Airwall run continuously for enterprise, public sector, and government customers, in environments where an outage or a data integrity problem carries real operational consequence for the buildings and the people inside them. Johnson Controls is seeking a Staff Site Reliability Engineer. You will be the senior technical owner of escalated production problems, capable of debugging a failure across application code, data pipelines, cloud services, and network paths, and driving it through to permanent corrective action rather than a restart and a hopeful note in the ticket. You will also plan and execute the infrastructure work that keeps those platforms healthy, with Terraform as your native language and change safety as your standing constraint. You will be a core team member of our engineering department, and participate in the on-call rotation, and occasionally join customer conversations when the severity of an issue warrants an engineer in the room. This role is based in Canada. We support Canadian government customers and commercial customers with Canadian data residency requirements, and this position works directly with those systems and their data.

Here's how to pick the right one and stand out in your application.
144.883Jobs
31.687IN
81%EN
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.
