Marketing Engineer

The Role

• Build and own Fonio’s data foundation, from the raw data to the models.

• Combine data from our own systems and third-party tools in one warehouse.

• Build the models the business runs on, starting with CLTV.

• Make the data easy for anyone in the company to use, and make sure everyone gets the same answer.

• Set up and run the data warehouse (e.g. Snowflake) using off-the-shelf tools: buy the plumbing, build the models.

• Build and maintain ETL and reverse-ETL pipelines, choosing cost-effective tools (e.g. Weld over Fivetran).

• Own the modelling layer in dbt (or similar), and automate as much as possible.

• Build a cohort-based CLTV model first, then other core models such as retention and payback.

• Define the key metrics (CAC, CLTV, churn, activation) once, and document them as the single source of truth.

• Open the warehouse to the team so anyone can query it and build dashboards with Claude, with the right access controls in place.

• Set up data tests and monitoring so people can trust the numbers.

• Work closely with the founders and the marketing team, turning business questions into models.

What you bring

• 3–5 years of hands-on experience with a modern data warehouse such as Snowflake.

• Experience with ETL and reverse-ETL tools.

• Strong SQL and dbt experience.

• You’re comfortable doing both the engineering and the modelling.

• You’re a super dedicated hustler: you own it end to end and move fast without waiting for a team around you.

• You’d rather automate a task than do it by hand twice.

What We Offer

• Competitive Salary: €65.000-€130.000

• Equity - you build it, you should own a piece of it.

• Food & drinks are on us (plus all the drinks your heart desires, and yes, we have protein bars and vitamins too).

• Relocation bonus (if you still need to move)

• Equipment of your choice - whatever makes you happy.
