Architecting the ResOps Squad: Roles, Skills, and Structure



The digital world is currently obsessed with "speed." We’ve spent the last decade perfecting the art of shipping code in minutes. But as our systems have become more interconnected, they’ve also become more brittle. We’ve built Formula 1 cars that shatter the moment they hit a pebble on the track.

If DevOps and SRE are about keeping the car fast and on the road, Resilience Operations (ResOps) is the specialized crew that ensures the driver survives the crash and the car keeps moving—even if it’s on three wheels.

But who actually sits in the ResOps garage? This isn't just "SRE with a different hat." It’s a strategic pivot from maintaining state to managing shock.

The "Hybrid Persona": The Battle-Scarred Diplomat

You can’t build a ResOps team out of junior devs. You need people who have smelled the smoke of a data center fire (metaphorically or literally). The ideal ResOps lead possesses a "Hybrid Persona":

  • The Technical Grit: They need the "battle scars" of a SecOps incident responder. They understand how systems fail under pressure and how humans panic during a "Severity 1" outage.

  • The Systems Vision: They need the "systems thinking" of an SRE. They see the infrastructure not as a list of servers, but as a living, breathing web of dependencies.

The Three Pillars of the Squad

A functional ResOps team isn't a monolith; it’s a triad of specialized skills designed to map, break, and translate.

1. The Dependency Mappers (The Cartographers)

These specialists use data to visualize how a single API failure cascades into a business shutdown.

  • The Real-World Example: During the 2021 Fastly outage, many companies realized their "internal" dashboards were useless because they pulled a single font file from a CDN that was down. The Dependency Mapper finds these "Shadow Dependencies" before the outage does.

  • Key Citation: Referencing the DORA (Digital Operational Resilience Act), these mappers focus on "N-th party risk"—the vendors of your vendors.

2. The Chaos Designers (The Stress-Testers)

They don't just run "drills"; they design "severe but plausible" fire drills.

  • The Real-World Example: A Chaos Designer might simulate a "Black Swan" event: The loss of a primary cloud region simultaneously with a localized internet backbone failure in a key customer market. * Success Metric: They move the needle on MTRL (Mean Time to Recovery of Logic), ensuring the business can still take orders even if the "Perfect World" tech stack is crumbling.

3. The Business Liaisons (The Translators)

The most critical—and often missing—link. They translate "99.9% uptime" into "Impact Tolerance" levels that CEOs and Boards actually care about.

  • The Metric Shift: They stop talking about "latency" and start talking about "Maximum Tolerable Period of Disruption" (MTPD)—a term championed by the Bank of England’s operational resilience framework.

Why the Reporting Line is Your Secret Weapon

If ResOps reports to the CTO, they will inevitably be "buried" in technical debt conversations. To be effective, ResOps should report to the Chief Risk Officer (CRO) or Chief Operating Officer (COO).

Why? Because resilience is a business risk, not a technical bug.

  • Neutrality: A ResOps lead reporting to a CRO can say "No" to a release that threatens the organization's survivability, without being overruled by a CTO focused on shipping speed.

  • Budgetary Weight: It moves resilience from a "maintenance" expense to a "capital" protection strategy.

Measuring What Matters: The ResOps Vital Signs

You cannot manage what you measure with the wrong yardstick. ResOps trades "Uptime" for "Survivability."

The Takeaway

Architecting a ResOps squad isn't about adding another layer of bureaucracy. It’s about creating a "Strategic Orchestrator" that sits above the silos of IT, Security, and Dev. It’s about hiring people who are comfortable in the chaos and giving them the authority to ensure that when the "unthinkable" happens, your business treats it as just another Tuesday.

In our next post, we’ll look at Part 2: Engineering a "Resilience-First" Culture, and how to stop rewarding "speed" at the expense of "survivability."

I Took My Own Advice in an Interview. Pure Storage Didn't Flinch.

I'm joining Pure Storage on March 2nd to be part of the technical marketing team, and I'm genuinely excited about it. During the interview process, I took my own advice from a blog post I wrote a few weeks ago and asked them the question that makes most candidates nervous: "What concerns do you have about me for this role?" They didn't flinch. They gave me real feedback. We had an actual conversation about fit, not just a polished interview performance. That's when I knew this was the right place. What Got Me Excited The conversations with Pure focused on enablement. Not campaigns. Not metrics. Enablement. How do we help the people in front of customers have better conversations? How do we give them what they actually need to succeed? Those questions resonated with me because I've done that work before. I know what it's like when you have the right materials at the right time. When customer stories are authentic and metrics are real. When enablem...

If I do the homework, you owe me a phone call. The death of decency in hiring.

Honestly, I almost didn't post this. You know how it is. You don't want to look salty. You don't want to look difficult. It’s easier to just roll your eyes and move on to the next application. But I can’t be the only one dealing with this nonsense, so I’m saying it. Here’s the situation: I’m interviewing for a senior role. Things are going great. The hiring manager is cool, we’re clicking, the vision matches. Then comes the homework. And not a 30-minute writing sample. They asked for the full package: A 12-month strategic plan for Analyst Relations. How to position them for MQs, Waves, the works. I sat down and did the work. I audited their competitors. I built the roadmap. I gave them a strategy I would usually charge a consulting fee for. I sent it off, ready to talk shop. The result? Ghosted by the human, rejected by the robot. No feedback. No "hey, thanks for the effort." Just a generic, no-reply template email: “We have decided not to move forward.” Since w...

The One Question That Terrifies Candidates But Wins Offers - It's not "How's the Culture?"

Image
If I’ve been a little quiet on here lately, it’s not because I’m sipping coconuts on a beach. It’s because I’ve been in the trenches. I’ve been doing the rounds—interviewing with a bunch of different companies, shaking hands (or bumping elbows), and sitting in a lot of hot seats. And when you do that many interviews back-to-back, you start to see patterns. You see the same generic questions, the same awkward pauses, and the same moment where the power dynamic shifts. It happens when the interviewer closes their laptop, leans back, and asks: "So, do you have any questions for me?" Most people play it safe here. They ask about work-life balance or what a typical Tuesday looks like. Those are fine, but let’s be real: polite questions don't get you the job. If you really want to stand out—and more importantly, if you want to know if you actually got the gig, you need to stop being a passenger. You need to be bold. You need to ask the questions that make your palms sweat. Her...
