[Hiring] Senior Data Scientist @Smallpdf

Role Description

We're looking for a Senior Data Scientist to help us answer some of the most important questions shaping Smallpdf's growth:

• How much value does each marketing channel really generate?
• What drives users to convert, subscribe, and stay?
• Where are we missing opportunities to improve our product and business performance?

You'll work at the intersection of Data Science, Product and Growth , using advanced analytics, statistical methods, experimentation, and causal inference to uncover what drives our business and what we should do next.

This is a hands-on, high-impact role for someone who enjoys owning complex problems end to end:

• Understanding the business challenge and working with raw data.
• Building reliable data models, conducting analyses, and turning findings into actionable recommendations.

You'll join our Data team, reporting to the Head of Data and collaborating closely with our Growth and Product leadership. You'll have the autonomy to challenge assumptions, investigate opportunities, and influence decisions that directly impact our business.

We're not looking for someone who simply reports what happened. We're looking for someone who can explain why it happened, what it means, and what we should do about it.

Qualifications

• Strong experience in applied Data Science or advanced analytics, ideally in a SaaS, product-led growth, digital product, or marketing-driven business.
• Advanced SQL and data modeling skills, including experience designing, building, testing, and maintaining reliable data models.
• Strong Python skills, with the ability to perform statistical analyses, develop predictive models, and build practical data products.
• Solid foundations in statistics, experimentation, and causal inference.
• Experience in Growth or Marketing Analytics, with an understanding of acquisition channels, conversion funnels, attribution, incrementality, and customer behavior.
• Strong product and commercial thinking.
• End-to-end ownership across the analytical lifecycle.
• Excellent communication skills.
• Curiosity, initiative, and a proactive mindset.

Requirements

• Experience working in a subscription-based or product-led growth business.
• Hands-on experience with marketing incrementality, attribution modeling, Marketing Mix Modeling (MMM), or quasi-experimental techniques.
• Experience building analytical frameworks or data products that have been adopted and used by business teams.
• Experience working in a small, high-impact data team.
• A demonstrated ability to influence Product, Growth, or Marketing strategy through rigorous analysis and clear recommendations.

Benefits

• Impact the way over 60 million people get work done every month.
• Push boundaries and dare to fail - that’s how we learn!
• Enjoy the flexibility of a remote work environment.
• 30 vacation days that you can take whenever you need them.
• Sabbatical leave for employees who’ve been with us for over 2 years.
• 16 weeks parental leave - 100% of your salary - for all new parents.
• A personal development budget of up to 2000CHF every year, plus days off for courses or training.
• Internal knowledge sharing and external coaching options during your working hours.
• Hack days to challenge you and your team, plus build amazing things.
