One of the companies we work with at Joppy is looking for a Lead Data Analyst to lead paid search analytics globally. They’re an international two-sided marketplace with several brands across many markets.

The question you’d own The company’s brands often bid on the same searches. When they compete for the same customer, did the business actually grow, or did spend just move from one brand to another?

Your job is to answer that with experiments, causal methods and good judgement, and to turn the answers into decisions on millions in paid search spend.

What you’ll do

- Prove what’s incremental. Design and analyze geo-split, channel and multi-brand experiments, and tell the team what really drives growth.
- Guide investment. Model marginal returns, LTV and payback across brands, and help SEM leaders decide where the next euro should go.
- Separate signal from attribution. Reconcile platform data with internal measurement and build the dashboards everyone trusts.
- Set the agenda. Own the SEM analytics roadmap and act as the go-to thought partner for SEM, Finance and Data Science.
- Raise the bar. Mentor analysts and review their SQL and methods. This is a senior IC role with no direct reports, but real influence.

You’ll likely have





- 6+ years in analytics, with examples of analysis that changed a business decision.
- Advanced SQL, plus Python or R for statistical work.
- Hands-on experience with A/B testing and experiment design. Bonus if you’ve used causal inference or geo-experiments and can explain where they break.
- Comfort leading big analytical projects and presenting to non-technical stakeholders.

Nice to have (they don’t expect all of these) Marketing or paid-search analytics (CAC, ROAS, LTV), marketplaces or multi-brand businesses, MMM, dbt.

Paid search experience is not required. If you’re a strong experimentation analyst from product, pricing or growth, they want to hear from you.

What they offer

- Long-term incentive plan (cash payout tied to company performance)
- Pension plan + private medical insurance
- 25 days PTO
- Adaptable hours, meal allowance, flexible comp (transport, nursery)
- Gym membership + annual wellness budget
- Office with snacks, fruit and regular team events
- Hybrid setup: office on Mondays and Thursdays, the rest is up to you. You need to live in Barcelona or be open to relocating.
