In 2025, sunday raised a 21 million dollar Series B led by DST Global Partners to accelerate product development and international expansion.

We are hiring a Senior Business Data Analyst to be a key analytical partner to our leadership, finance, and country teams.

The Role

Our Data team is small, business and product oriented, and focused on outcomes. As a Senior Business Data Analyst, you sit at the intersection of data, business performance, and operations.

You turn data into insights and recommendations that drive revenue growth, profitability, and operational efficiency. You help Sunday understand what is happening in the business, why it is happening, and what we should do next.

What Success Looks Like

Over the next 12 to 18 months, your main challenges will be to:

• Rebuild and roll out our core business dashboards so that leadership and country teams rely on a single, trusted view of performance.
• Bring clarity to our metrics and definitions so everyone at sunday talks about the business in the same way.
• Help leadership and country teams make better decisions on where to invest, which markets to prioritize, and how to improve profitability.
• Increase data self service for internal teams so they can answer most of their day to day questions without relying on the data team.

What You'll Do

• Partner closely with Leadership, Finance, Operations, Sales, Marketing, and Product to frame business problems, translate them into analytical work, and turn results into clear recommendations and decisions.
• Own core business metrics and dashboards. Redesign and maintain the key views we use to run the business so they are trusted, actionable, and used every week by leadership and country teams.
• Build and maintain self service reporting in our BI tools and act as a go to person for internal teams, including country leaders and account managers, to navigate our data, understand tables and metrics, and find the right sources of truth.
• Run deep dive analyses on topics such as country or segment performance, funnels, cohorts, experiments, and unit economics, and work with Analytics and Data Engineers to keep our models, documentation, and metric definitions aligned while driving clear business impact.

In a typical week, you might:

• Join a leadership or country review to walk through performance, explain what is behind the numbers, and align on next actions.
• Spend time with account managers or in restaurants to understand what is happening on the ground and turn these observations into hypotheses to test in the data.
• Deep dive into a specific topic, for example why adoption is stalling in a country or why a segment is underperforming, and turn your findings into a simple narrative.
• Ship an improved version of a core dashboard, announce it to stakeholders, and run a short session to show them how to use it.

About You

• You are a senior analyst with strong ownership. You are comfortable driving a business topic from an open question to a clear decision and pushing back when needed.
• You are highly business minded. You understand revenue models, unit economics, and trade offs and you enjoy working closely with leadership, finance, and commercial teams.
• You thrive in ambiguous, fast changing environments and can structure messy business problems into clear analytical steps.
• You communicate clearly with non technical stakeholders and tell a compelling story with data that connects directly to business impact.
• You are comfortable going on site in restaurants to observe reality, understand operational friction, and build empathy with staff and guests so your recommendations are grounded in the field.

Skills & Experience

• 5+ years experience as a Business or Data Analyst or similar role in a digital or tech company, ideally in a revenue, strategy, or operations focused context, for example business operations, revenue operations, strategy, or finance partnering.
• Strong proficiency in SQL and experience with a modern cloud data warehouse, such as BigQuery.
• Experience with BI and data visualization tools, for example Metabase, Looker, Tableau, or Power BI, and with presenting insights and recommendations to senior stakeholders.
• Strong analytical foundations. You are comfortable with funnels, cohorts, experimentation basics, and unit economics and you can translate them into business language for non technical stakeholders.
• Nice to have: experience with dbt, Dagster, Amplitude, or Python for deeper analysis.

Our Current Stack

• Cloud Platform: Google Cloud Platform (GCP)
• Warehouse and Modeling: BigQuery, dbt
• Orchestration: Dagster
• BI and Product Analytics: Metabase, Amplitude

Compensation, Perks and Benefits

• Competitive salary and stock options
• Location: Paris or London, hybrid (3 day/week on site)
• 100% health coverage for you and your children
• Flexible time off / free vacation policy
