Job description

Deblock is the fastest-growing consumer fintech in Europe and is on a mission to bring on-chain money to the 99% who have a salary, not a seed phrase. We combine banking-grade compliance with on-chain technology to build a radically better way to save, spend, and invest across euros and digital assets.

This isn’t a role for setting campaigns live and checking back on Friday. You’ll run our paid acquisition in Italy and France day-to-day across Meta, TikTok, Google, and Apple Search Ads. You’ll launch, test, cut, and scale based on data. Expect long hours and high standards: we want work that’s fast and right. You try new things, make mistakes quickly, correct them and improve.

What you'll be working on

• Measure the exact performance of every marketing initiative: CAC, conversion, activation and retention by channel and cohort. No vanity metrics.
• Turn results into clear calls for the next round. What worked, what didn't, and what we change next week.
• Run focused initiatives from idea to launch to post-mortem. Partnerships, communities, local activations: the hard-yards work that compounds.
• Own the weekly numbers, hold the team to its targets, and push the business to grow.
  

What we are looking for

• You live in the data. SQL, agentic workflows, and spreadsheets are second nature, and you can spot real signal from the noise.
• You'll do the unglamorous work yourself, from building the list to running the event to cleaning the data.
• You think in returns, not activity. Every initiative has a cost, a target, and a verdict.
• You hold people to account with numbers, not opinions, and you say what the data says.
• You're a self-starter with a founder mentality. No hurdle is too big.
• You're fluent in Italian

What will make you stand out

• 3+ years in growth, business analytics, strategy or operations
• Experience in fintech, neobanking or a fast-growing consumer app
• Hands-on with SQL and mobile attribution tools and agentic workflows
• Track record of owning and delivering projects from the ground up
• You have a founder mentality
• You speak French

What you'll get

• Competitive salary
• Stock options
• The best tech for your job
• 25 days paid holiday (excl. bank holidays)
