New marketing tools have always created new marketing jobs.

Google Analyticscreated the web analyst.
Marketo and HubSpotcreated marketing ops.
A/B testing toolscreated the optimization specialist.

Each time, the marketers who learned to build with the new tool first got the title, the budget and the raise.

AI agentscreated the marketing engineer.

AI agents are the biggest new tool marketing has had. This time the job it creates isn’t a channel. It’s the whole stack: any task that runs by hand can now run as a system.

Most teams haven’t noticed the shift.They use AI mainly for prompting. Everything else still waits on someone.
A few marketers already build systems.They turned a weekly report into a report agent, and built pages for 50 target accounts overnight.
You might already be a marketing engineer.If you’ve built a Zap nobody requested, rebuilt a broken dashboard or wired n8n into a team workflow, your work has outgrown your title.
Companies now have a name for the role.Marketing ops keeps the stack running. A marketing engineer builds on top of it.
We’ve seen this before with CRO.CXL trained the first wave of conversion optimizers when CRO was nobody’s job title. Now it’s a role on every serious growth team. Marketing engineer is next.

Today a landing page waits on a designer and a lead-routing fix waits on engineering. A marketing engineer builds both with AI, the same week, on the CRM and GA4.

“The best part was watching the engine catch things I tell clients all the time. My first brief put the $500 ask in front of cold traffic, and Gate 1 flagged it: don’t lead with the heavy ask.”

No customers yet, so the ICP is built from reviews, Reddit threads and US research, with every unproven line tagged.

“We’ve never used VS Code or Claude Code before. We’ve been running in AI-assisted mode only. This has changed the game entirely… Before the cohort, I was having issues with our chosen ICP, but the dossier exercise helped me nail it down fast.”

Subject: CXL Marketing Engineer certification

I would like to take CXL's Marketing Engineer certification.

When does it start, and how much time does it take?

The cohort starts Monday 11 January 2027 with setup. Live sessions run every Tuesday from 19 January to 9 March at 3 PM UTC (10 AM ET, 4 PM CET). Plan on an average of 1 hour a day: a 90-minute live session each week, plus prep and building at your own pace. Setup comes first, in week 0, opening Monday 11 January: about 3 hours on demand, with technical assistance from the CXL team.

Who is it for?

Marketers with at least 2 years in ops, growth, demand gen or content who want to build what marketing engineer roles ask for, in their current job or the next one.

Do I need to code?

No hand-coding. You describe what you want, AI writes the code and the SQL, and you check the result. Checking is a skill the program teaches, from schema-validated output in week 3 to sanity-checking AI-generated numbers in week 6.

Come with a working laptop and admin rights on the tools you want to connect. You build on your own data, over MCP connections, the standard way AI tools connect to other software. You decide what gets connected and what does not.

What do I build?

One system, a layer a week: a context repo, n8n workflows, LLM steps with evals, and a capstone in one of three tracks. Campaigns goes from brief to reviewed campaign. Content goes from brief to checked draft. AI visibility tracks how ChatGPT, Gemini and Perplexity answer about you, and fixes what they get wrong. On top of it you build a deployed app, a reporting layer and personalization for 50+ target accounts.

How do I get certified?

You pass on seven criteria. It runs unattended for 14+ consecutive days, with 90%+ of runs successful. Its output meets the eval threshold you set in week 1. The result is measured honestly against your baseline. The app and the personalization batch both work. An approval step and a cost cap are set. An assessor can run it from your README. And you defend it in the community, answering the reviewers’ questions.

Show measured improvement over your baseline and you earn the credential with distinction. One resubmission is allowed within 30 days.

What is the defense?

You post your build in the community with a short readout of what your system does and what it moved. Reviewers ask questions in the thread and you answer them. It is the closest thing to a hiring manager asking you to walk them through your work.

How do I prove a system like this is worth it?

A marketer on Reddit asked it directly: “revenue metrics? Calls booked?” Week 6 answers it on your own data: baseline against now, tied to pipeline or hours saved, written up by a weekly report agent. That number headlines your certification.

Is a marketing engineer just marketing ops with a new name?

There is overlap, and the best ops people already work this way. The difference is what you can show: a system you built, running on your own customers and channels, that you can demo and fix. That is what marketing engineer job ads screen for, whatever the title on your CV.

Can I use my company’s data?

Yes, that is the default. You build on your own customers and channels, over connections you control. If you cannot use company data, a sample company dataset is ready for you.

I am in the November sprint. Does it count?

Yes. The sprint builds three layers of this system: the Marketing Brain (week 1), the campaign engine (week 4, campaigns track) and the reporting agent (week 6). You start January with them already built.

What does it cost?

$1,199 until 10 January, 25% off the usual $1,599. It includes the January cohort and future cohorts, every update to the systems, a year in the community, and 80+ on-demand courses and every minidegree on the marketing behind the systems.

How is this different from other marketing engineer courses?

Most teach one vendor’s tool and certify attendance. This one is vendor-neutral, 8 weeks deep, and graded on a system that runs in production, defended in the community.

How is this different from asking ChatGPT?

ChatGPT answers questions. Here you build a system: one that runs on your own customers and channels, that an assessor checks, and that you defend in the community before it counts. ChatGPT will help you do a task faster. It will not run your workflow unattended for 14 days, or check that its output can be trusted at scale.

Can my company pay for it?

Yes. Use the email on this page to send your manager the details. Everything you build runs on the company’s tools and stays with the company.
