What does it really feel like to be the person who gets paged when everything breaks?
In this episode, we sit down with Rachel to talk about the reality of on-call engineering — the stress, the uncertainty, the sleepless nights, and the systems that can turn chaos into calm. From false alarms at 3 a.m. to high-pressure incidents with real business impact, Rachel shares honest stories, hard-earned lessons, and practical ways teams can make on-call more sustainable.
We explore what good incident management actually looks like, why alert fatigue is so dangerous, how strong escalation paths and runbooks reduce panic, and why psychological safety matters just as much as technical skill. We also talk about postmortems, monitoring, ownership, and how on-call can become one of the fastest ways to truly understand the systems you build.
Whether you love on-call, fear it, or are still figuring out if it is for you, this conversation is full of relatable moments, useful insights, and real-world advice for bringing more calm to operational chaos.
