A Fractional Marketing Engineer
for your marketing team.
Essential Code is a small senior team that builds the pages, integrations and AI workflows your marketing plan needs when your own engineers are busy with the product. Some companies call the role GTM engineer, growth engineer or marketing technology engineer. Month to month, nobody on your payroll, and small changes to copy, a section or a tracking tag go live the same working day.

The problem
How much of your marketing plan is sitting behind a developer you do not have? Enough work to keep a senior engineer busy, and nowhere near enough to hire one.
New sections and landing pages sit in an IT or agency queue while the campaign they belong to is ready to launch.
Integrations between your CMS, CRM, and analytics are held together with workarounds.
Your team wants to run its work through AI tools, but nothing is wired up, and connecting the stack so AI can draft and publish is senior technical work.
Performance issues, bug reports, and the customer feedback that needs a developer sit unaddressed because nobody owns them.
Freelancers disappear. Agencies quote projects and go quiet between them. Internal developers stay on product.
The Reality
You do not need another project, or another hire you cannot justify. You need senior capability that is just there.
The Cost
What it costs you
None of it shows up as a line in a budget. It shows up as the campaign that ran without its landing page, the launch week where the page went live on the Thursday, and the integration that was going to save your team hours every week and is still next quarter. The work is still there when you finally get to it. The moment is not.
Core Belief
Good marketing teams move faster than their tech.
The gap between what marketing needs to execute and what the technical setup can support does not close on its own. It grows. There is always real work waiting: pages, integrations, performance, a migration nobody has time to run. It arrives in waves, and a wave is the hardest kind of work to staff for.
Hiring fills it slowly and expensively. A senior full-stack engineer in Austria runs around € 90.000 to € 100.000 gross a year (SalaryExpert/ERI, 2026), and employer costs push the real number well over € 120.000. That is a long search and a heavy commitment. There is a lighter way to get the same senior capability, with nobody on the books.
The Payoff
You get your momentum back
A campaign needs its landing page ready to take visitors and its tracking checked before you turn on the ads. We build and test both around your launch plans. When the offer changes, you can bring the update straight to the team that already knows the page and how it connects to your marketing tools.
Scope
What we handle
Three areas, with someone accountable for finishing the work. The note under each one says which tier covers it.
Website development
Momentum and Ownership. New markets and languages are Ownership.
New pages, sections, or components in your CMS
Performance and Core Web Vitals, owned instead of ignored
Technical debt in your frontend, cleaned up as you go
New markets or languages
Migrating your site to a headless stack, quoted as a separate project
The AI control center
Ownership, built and kept running.
MCP and AI workflows set up and kept running, so your team can drive the CMS with their AI tools
A governed publish flow, with a human accountable at every publish
Integration work
Fixes to the integrations you have are Momentum. New integrations and work with your agencies are Ownership.
Connecting your CMS to your CRM, ERP, analytics, or other tools
Search, forms, and third-party integrations
Your SEO and SEA agencies, we speak their language and do the technical work they ask for, so you are not stuck in the middle
Held together properly, instead of with the next workaround
Your Stack
We work best in headless stacks. If your setup is reasonable, we work within it. If it is not, we will tell you.
How It Works
Our process
We get to know your setup
We get access to your website and marketing tools, check how changes go live, and look at what you are about to launch. That gives us the setup and context to get the campaign work moving.
You get a private Kanban board
Add requests whenever something comes up, with the campaign date and any copy or assets we need. You set the priorities, so we know which changes your launch depends on.
We build, check, and publish
We take the work through to the live site and keep you updated on the board. For a campaign page, that includes checking the form and tracking before you send traffic to it.
Pricing
Priced by what we own.
Start with one thing built and live, then pick a monthly tier. The tiers differ by what we own, never by hours or a limit on requests.
You are paying for a small senior team that knows your setup and moves it forward. There is no hourly tracking.
One thing, built and live. You pick it on the kickoff call from these four:
A campaign landing page in your CMS, with the form and tracking checked before traffic arrives
Your main conversion measured correctly, including the consent signal Google requires for EU visitors
Your website form writing leads into your CRM with the lead source attached
Your team’s AI tool connected to your CMS, with a written brief of your brand and buyers
It ends with a walkthrough of what is live. It is not an audit. If your stack cannot take the work, we say so on the kickoff call and you do not pay. Sign up for a monthly tier within 30 days of the walkthrough and the full € 1.990 is credited against your first invoice.
You bring the requests, we get them live.
New pages, sections and components in your CMS, and campaign pages with form and tracking checked before traffic arrives
Small changes to copy, a section or a tracking tag live the same working day
Tags, conversion events and consent signals kept working
Page speed monitored and regressions fixed
Fixes to the integrations you already have
A private Kanban board where you add work whenever it comes up and set the order
A review of what shipped
Everything in Momentum, and we own the technical side of your marketing.
New integrations built between your CMS, CRM and analytics, so they agree on what a lead is and the report on which content produced pipeline keeps running
Your AI control center built and kept running by us
A roadmap we bring: we propose what to fix and build next, and ship improvements you did not have to ask for
Planning calls and a written report on what shipped and what your conversion and speed numbers did
We work directly with your SEO and SEA agencies and your CTO
New markets and languages added to your site
Nothing here is binding. You describe the work, we tell you whether we are the right people for it.
Momentum and Ownership are month to month. Cancel or pause with 30 days notice. All prices are net, excluding applicable VAT.
