Certifications our operators train against
75% of knowledge workers already use AI at work. 71% of leaders say their team isn't ready to get value from it.
Access isn't the gap — capability is. Staff Stack operators are certified on the AI workflows that actually ship agency work, so the team you hire on Monday is running on Wednesday.

Proof before the interview (not after the first invoice)
Most hiring processes ask you to guess if someone can deliver. We'd rather show you.
Before you interview anyone, you'll see:
- the deliverable from a timed, role-specific practical test
- the QA checklist they used (or missed)
- a 2-minute Loom update (how they communicate async)
- an AI workflow trace (prompt → output → edits → final)
- a tool fluency checklist for your vertical
If it's not in the scorecard, it's not a claim we expect you to believe.
Get a shortlist in 7 days (most roles). No resume flood.
"Every agency tells me the same thing: they don't need more résumés, they need people who can actually ship the work. That's what StackCertified is for — proof before the interview."
The Stack System — Why Agencies Trust Us
We're not a job board. We're delivery infrastructure. Our systems ensure your operators ship quality work from day one.
Ready in 7 Days
Pre-certified operators from our bench, onboarded and delivering within a week — not months.
AI-Native Workflows
Operators who turn messy briefs into shipped work using AI tools — not button-pushers waiting for instructions.
Backup Bench Ready
Pre-certified backup operators in each role family, so replacements happen in days, not weeks.
Your Delivery Infrastructure, Not a Directory
Agencies don't need another job board. They need operators who can take a brief and ship. Our StackCertified process tests for exactly that — AI-assisted work, clear communication, and quality delivery under deadline pressure.
- Role-specific practical tests
- AI workflow proof required
- Loom + async communication screening
- Shareable candidate scorecards
"AI-native" doesn't mean "let the model do it"
AI-native operators aren't magic. They're disciplined.
We look for people who can:
turn a messy brief into a clean plan (and ask the right questions early)
use AI to draft faster, then verify and improve before shipping
document decisions and edge cases so work doesn't get lost in Slack
escalate blockers with context (not panic, not silence)
use AI safely — brand-voice guardrails, hallucination checks, and clear escalation on edge cases
In certification, we score for verification and judgment — not just speed.
AI is part of the workflow. QA is the guardrail.
Built for Agency Verticals
We specialize in three agency types. Each vertical has dedicated certification tracks, role-specific tests, and pre-built SOPs.
Retention & Klaviyo
Production capacity for email, SMS, and CRO agencies. Ship more campaigns without breaking deadlines.
Promise: Ship X campaigns/week with <Y% QA error rate
StackCertified Retention & Klaviyo Roles
What the first 7 days looks like
From intake to stable delivery cadence — here's what happens.
Intake
You share the role + examples of "good work." We align on tools, hours, and KPIs.
Onboarding
Your operator is set up in your tools, briefed on your SOPs, and given a first task bundle.
First outputs
They ship real work. Not training tasks. We review quality against checklists.
QA + refinement
We tighten the workflow: templates, naming conventions, revision loops, escalation rules.
KPI baseline
You get a simple baseline: throughput, turnaround time, QA error rate, communication quality.
Stable week-one cadence
You should know: "Can this person take briefs and ship, without chasing?"
If a role is unusually specialized, we'll tell you upfront if it needs longer than a week.
Staff Stack isn't for every agency
We're a fit if you want:
- one (or a few) full-time operators you can rely on
- proof of execution before you hire
- repeatable delivery — not heroics
We're not a fit if you want:
- the cheapest possible labor
- a dozen resumes by tomorrow
- someone to "figure out your process" with zero direction
If that honesty saves you a bad hire, it's doing its job.
What Agency Leaders Say
Agencies using StackCertified operators to add capacity without adding chaos.
"We added two Klaviyo email builders through Staff Stack. They passed their certification tests before we even interviewed them — we could see their actual flow builds. Now we're shipping 40% more campaigns without adding to our core team."
Sarah Chen
Founder, Retention Agency (Klaviyo Partner)
"Our strategists were drowning in campaign builds and reporting. The ad ops assistant we hired handles all the execution work now. Our strategist time freed up by 15+ hours per week — exactly what we needed to take on more clients."
Marcus Williams
Head of Operations, Performance Media Co
"Project overflow was killing our deadlines. We brought on a StackCertified Shopify developer who hit the ground running — their certification included fixing a real bug under time pressure. That's exactly the test that matters for our work."
James Park
Technical Director, Shopify Plus Agency
"The QA specialist we hired catches issues our team was missing. Links, rendering, UTMs — they have a checklist for everything. Our error rate dropped significantly in the first month. Worth every penny."
Emily Rodriguez
Managing Partner, Email Growth Partners
"We needed reporting capacity fast. The analyst we got can build Looker dashboards, automate reports, and actually understands attribution. They proved it in their certification — not just talked about it in an interview."
David Kim
CEO, Conversion Lab Agency
