Jobbeschreibung

Every company in Germany has to keep books, file VAT and produce annual accounts. It is unavoidable, unloved and far more expensive than it needs to be, and it lands hardest on the smallest businesses.

mika is the infrastructure that takes it off them. None of this work is optional, which is what makes it infrastructure rather than a product, and the point of building it is to lower the cost of doing business in Germany.

From 100 to more than 700 customers in eight months, and still a small team. Which is why this role is broad, why you own an area instead of a slice of one, and why your scope grows at the speed you do. We work in English, we are international, our market is German. y positive surprise. Choosing one is also a big decision: several steps and several touchpoints before anyone moves. One ad and one landing page do not close it.

Tasks

You run our growth experiments end to end. You bring the questions worth answering, agree the hypothesis with the founders, build the test yourself, and measure it properly.

End to end includes the measurement. Instrumentation, attribution and whatever needs fixing in HubSpot for a result to be trustworthy are part of running the experiment, not somebody else's ticket.

We are looking for a marketer who can build, not an engineer who supports marketing. Knowing which hypothesis is worth the week matters more here than the code, and you write the German variants yourself instead of waiting for copy.

what you will do

• Shape the test agenda with the founders, and sync with the rest of growth wherever an experiment touches their area
• Build what the test needs: landing pages, flows, tools, integrations, automations. The simplest version that will confirm or kill the hypothesis, in days (or better hours) rather than sprints.
• Be self-sufficient
• Make the measurement trustworthy. Tracking, attribution, the data model and the HubSpot side of it. Our pipeline data is not yet reliable enough to steer by, and getting it there is part of the job.
• Read results honestly, including when they kill your own idea, and write down what we learned so nobody relearns it in six months

Requirements

what you bring to the table

• AI-native, not AI-curious. Claude or an equivalent is your daily sparring partner rather than a tool you open occasionally. You augment your own output with it and you automate the parts of your job that should not need a human. Here it is a baseline, not a differentiator: you would find working without it slow.
• You are a marketer first. Funnel, messaging, positioning, offer, what actually moves a number. We're not looking for an engineer who "builds what marketing wants"
• We have a strong bias towards people who have been entrepreneurs themselves. You have built and launched something of your own, or run a function as if it were your own company.
• You have run experiments without being handed hypotheses. Talk us through a real one: what you expected, what happened, what you changed.
• Visual and copy judgment. You can lay out a page that looks intentional, write the headline, and say precisely why a weak version is weak.
• Ideally you have worked with Hubspot, BigQuery, Chargebee/Stripe

German at C1 or above is required. You write the variants and the messaging you test, and in this market that judgment cannot be delegated. English at B2 or above, since English is our working language.

the level we are hiring at

This is a senior individual contributor role and it stays one. Your influence grows through the scope of what you own and what you are trusted to decide, not through people reporting to you.

We care about the combination more than the years. Somebody with two years who hasgenuinely run their own experiments end to end beats somebody with ten who has alwayshad the hypothesis handed to them or people who executed for them.

We are relaxed about what this has been called on your CV. Growth engineer, growth hacker, technical marketer, creative technologist, solo founder who built their own funnel: if the description above is you, apply.

Benefits

• Base 70,000 to 100,000 + EUR depending on experience, plus stock options.
• Three rounds: an intro conversation, a working session with a short case, and a final round with the founders. Depending on seniority there is an optional fourth conversation with one of our investors or mentors. One meeting happens in person in Berlin, and you hear back within a week at every stage, including if the answer is no.

why mika?

Real influence on what we test. You shape the agenda with the founders rather than working through somebody's backlog, on a funnel with a lot of untested surface and a budget behind it.

Room, and the expectation that you use it. We hire people who do not need managing and then give them space to grow into more than the job they were hired for. Fully flexible hours apart from the daily standup.
