Consolidate and aggregate data from product, marketing, CRM, and transactional systems into reliable datasets.
Perform product analytics to measure feature usage, user journeys, and retention drivers.

Build ML models for revenue optimization, churn prediction, segmentation, and subscription forecasting.
Analyze marketing performance to measure acquisition efficiency, LTV, and campaign ROI.
Translate analysis into action: propose product changes, growth experiments, and operational KPIs.
Report results using concise dashboards, reports, and data storytelling for non‑technical stakeholders.
Work cross‑functionally with product, marketing, engineering, and country managers to standardize metrics and training.
Maintain data quality: identify polluted data, propose remediation, and implement robust ETL checks.

Good to know if you are moving

RealAdvisor is a Swiss company, so international hires may need to navigate Swiss work permit processes if working from Switzerland, but the Spain-based roles are likely remote or based in Spain, offering flexibility.
The company uses Workable for its careers page, indicating a modern and structured hiring process.
Fluency in Spanish is essential for the Spain-focused sales roles, and German is a plus for the Swiss market.
As a PropTech company, RealAdvisor offers a chance to work at the intersection of technology and real estate, a growing sector in Europe.
The company is relatively small, which may offer employees more direct impact and visibility in their roles.
